1. History, Function, and Use

Ginseng has held a special place in traditional Chinese medicine for more than two thousand years, where the root is regarded as a substance that helps the body maintain its natural balance. This idea aligns with the concept of homeostasis, the body’s ability to keep internal processes stable despite external strain. Ginseng was seen as a plant that reinforces this stability by supporting the body’s capacity for recovery. The root was traditionally used to promote vitality, a term that in medicine refers to the combination of physical energy, mental clarity, and immune system resilience. According to tradition, ginseng was sometimes worth more than gold in earlier times, which reflects not only the scarcity of the wild plant but also the belief that it had a profound effect on the entire organism.

The Chinese name Jen Shen, “human root,” refers to the shape of the tuber, which with a bit of imagination resembles a human body. In traditional medicine, this resemblance was not seen as coincidental but as an indication that the root could support the whole body. This aligns with the old principle of the doctrine of signatures, the idea that a plant’s shape says something about its effect. Although this principle is no longer used as a scientific basis today, modern research has shown that ginseng contains substances that influence multiple physiological systems at once. For example, ginsenosides, the main bioactive compounds in ginseng, can affect both the nervous system and the immune system. The nervous system is the body’s communication network that processes signals and directs responses, while the immune system is responsible for protection against pathogens. The fact that a single plant can influence both systems explains why ginseng was viewed in traditional medicine as a remedy that supports the entire organism.

Ginseng has been known in Europe since the seventeenth century, but it was not until the twentieth century that the plant was cultivated on a larger scale and studied scientifically. Recognition of ginseng as a medicinal plant grew out of studies showing that the root can influence processes such as metabolic regulation, the set of mechanisms by which the body produces and uses energy. These metabolic processes determine, among other things, how efficiently cells convert nutrients into energy and how well the body can adapt to physical or mental strain. Interest in ginseng grew quickly as a result, and the root developed into one of the best-known natural remedies in the world.

Ginseng is especially deeply rooted in Asian culture, where it is used to support both mental and physical performance. The root is often used to support mental clarity, a term referring to the ability to sustain attention, process information, and keep cognitive functions stable. Cognition encompasses all the processes involved in thinking, learning, remembering, and making decisions. Ginseng is also used to support physical performance, which relates to endurance, muscle strength, and recovery after exertion. In this context, the plant is regarded as an adaptogen, a substance that helps the body cope better with stressors. Stressors are stimuli that place a burden on the body, such as illness, fatigue, emotional pressure, or intense physical exertion. Adaptogens influence the stress response by modulating the neuroendocrine system, the system in which the nervous system and the hormonal system work together to regulate stress hormones such as cortisol.

Ginseng is most commonly used in the form of dried powder, which can easily be processed into tea, capsules, or extracts. Within these uses, a distinction is made between red and white ginseng. White ginseng is the dried root in its natural form, while red ginseng is first steamed before being dried. Through this steaming process, the ginsenosides undergo chemical changes, which shifts the composition of the active compounds. These changes can affect bioavailability, a term referring to the extent to which a substance can be absorbed and used by the body. Red ginseng is therefore often considered more potent, while white ginseng is seen as milder. Both varieties are used to support overall vitality, but the choice between red and white depends on the desired intensity of the effect and the sensitivity of the user.

2. Ginseng Species

2.1 Panax Ginseng

The Latin name for ginseng is Panax ginseng. The word Panax is derived from the Greek panakos, meaning “all-healing.” This name reflects the centuries-old belief that the plant can support a broad range of bodily functions. Although the term should not be taken literally, it fits with modern findings showing that ginseng influences multiple physiological systems at once. This is mainly due to the presence of ginsenosides, bioactive compounds capable of modulating both the nervous system and the immune system. The nervous system is the body’s communication network that processes signals and directs responses, while the immune system is responsible for protection against pathogens. The combination of effects on these systems explains why ginseng was regarded in traditional medicine as a plant with an exceptionally broad range of action.

Ginseng is an herbaceous plant that can grow to about thirty-one inches tall. The flowers are small, yellowish-white, and barely noticeable, which is typical of plants that derive their value not from their above-ground parts but from their root. The most characteristic part of the plant is indeed the root, which is cylindrical in shape and has numerous branches. These branches increase the surface area in which ginsenosides are stored, which contributes to the medicinal value of older roots. The root is usually three to five inches long, sometimes longer, and about three-quarters of an inch thick. The bark has a light yellow to light brown color, while the interior is white to yellowish. These color differences reflect the concentration of secondary metabolites, substances the plant produces to protect itself against stressors such as cold, drought, or insects. Secondary metabolites are often the same substances that are used in medicine because of their biological activity.

Ginseng belongs to the ivy family (Araliaceae) and is therefore related to ivy. This family includes plants known for their ability to thrive in shaded, moist environments. The plant originates from the mountain forests of East Asia, where it mainly grows on shaded slopes with a temperate climate. These natural conditions matter because ginseng is sensitive to light intensity, soil quality, and temperature. The plant develops its highest concentration of ginsenosides when it grows slowly in cool, humus-rich soils. This explains why ginseng cannot easily be grown everywhere in the world: the plant needs a precisely defined ecological environment to develop its characteristic composition.

Today, ginseng is primarily cultivated in Korea, known for its high-quality red ginseng, but important growing regions can also be found in Japan and northeastern China. These regions offer the combination of climate, soil structure, and elevation needed for optimal development of the root. The specific growing conditions determine not only the quality of the root but also the ratio between different ginsenosides. This matters because different ginsenosides have different physiological effects. Some influence the stress response through the neuroendocrine system, the system in which the nervous system and hormonal system work together to regulate hormones such as cortisol. Other ginsenosides have an antioxidant effect, meaning they neutralize free radicals. Free radicals are unstable molecules that can damage cells and contribute to aging and inflammation. The variation in ginsenosides explains why ginseng is regarded, in both traditional and modern medicine, as a versatile plant with a broad range of action.

The natural growing conditions for ginseng are thus relatively specific, which means the plant cannot easily be cultivated everywhere. When ginseng is grown under unnatural conditions, for example in environments that are too warm or too bright, the concentration of the main bioactive compounds decreases. This makes clear why authentic Korean and Chinese ginseng is so highly valued worldwide: the geographic and climatic conditions of these regions directly contribute to the pharmacological quality of the root.

2.2 Origin and Distribution

Ginseng originates from the mountain forests of East Asia, an environment that, thanks to its cool temperatures, high humidity, and filtered sunlight, is particularly well suited to the slow growth the plant requires. This natural habitat explains why ginseng mainly occurs in the north of Korea, northeastern China, and southeastern Siberia. In these regions, the root develops a high concentration of ginsenosides, the bioactive compounds responsible for its medicinal effects. Ginsenosides are substances that influence, among other things, the nervous system, which processes signals and directs responses, and the immune system, which protects the body against pathogens. The plant produces these compounds as part of its secondary metabolism, a biological process in which plants create substances to defend themselves against stress, cold, or insects. The harsher the growing conditions, the richer the root generally becomes in these protective substances.

In the past, ginseng roots were mainly gathered from the wild. Because the plant grows slowly and can only be harvested after several years, this method of harvesting quickly led to scarcity. The high value of ginseng in traditional medicine, combined with its limited availability, drove the price up to levels that, according to tradition, sometimes exceeded that of gold. Growing demand made it necessary to begin cultivating ginseng. Through controlled cultivation, growers could replicate the conditions needed for ginsenoside development, although quality still depends heavily on factors such as soil structure, shade, and temperature. Today, ginseng is grown not only in Korea and China but also in Japan and the United States, where suitable climate zones have been found that approximate the plant’s natural conditions.

With the worldwide spread of traditional Chinese medicine, interest in ginseng has grown substantially in other parts of the world. The plant is increasingly regarded as an adaptogen, a substance that helps the body cope better with stressors. Stressors are stimuli that place a burden on the body, such as illness, fatigue, or emotional pressure. Adaptogens influence neuroendocrine regulation, the interplay between the nervous system and the hormonal system that determines how the body produces and breaks down stress hormones such as cortisol. Because of this regulating effect, ginseng is used in many countries to support vitality, recovery, and mental balance.

Awareness of ginseng is also growing in the Netherlands, partly due to increasing interest in natural health products. Cultivation initiatives have emerged showing that, with careful management, ginseng can also be grown in Dutch soil. One example is Holland Ginseng, a family business in Soerendonk that has grown ginseng and still handles its sale. The introduction of ginseng into Dutch agriculture shows that the plant is no longer solely an exotic product but a crop that can adapt to new growing regions when ecological conditions are carefully replicated.

Ginseng has been known in Europe since the seventeenth century, after travelers and missionaries brought the root back from Asia via trade routes. Interest grew in the centuries that followed, but it was not until the twentieth century that conventional medicine began to study the plant systematically. Studies focused mainly on the action of ginsenosides and their influence on processes such as metabolic regulation, the set of mechanisms by which the body produces and uses energy. The positive research results led to ginseng being officially recognized as a medicinal plant. This recognition has contributed to the further spread and acceptance of ginseng in the Western world, where the plant has since gained a firm place in both traditional and modern health practices.

2.3 Varieties of Ginseng

Several types of ginseng are distinguished in trade and in medicine, and although they are often grouped together colloquially, they differ clearly in chemical composition, physiological effect, and traditional use. These differences arise because each species grows in its own ecological region, with unique soil structures, temperatures, and stress factors. Plants respond to their environment through secondary metabolism, the process by which they produce protective substances that often have the same bioactive effects that are used in medicine. As a result, each ginseng species develops its own profile of ginsenosides, the main medicinal compounds that influence, among other things, the nervous system, which processes signals and directs responses, and the immune system, which protects the body against pathogens.

Korean ginseng, usually referred to as Panax ginseng, contains the highest concentration of ginsenosides. This is because the plant grows in cool, shaded mountain regions where the root matures slowly. Slow growth increases ginsenoside production because the plant has more time to build up these protective substances. This high concentration explains why Korean ginseng is traditionally seen as the most potent variety. The root has a pronounced effect on metabolism, the set of processes by which the body produces and uses energy, and on hormonal balance, the system that regulates hormones such as cortisol, adrenaline, and insulin. Because of this broad effect, Korean ginseng is often used for fatigue, stress, and recovery.

Japanese ginseng is also used for medicinal purposes but contains fewer ginsenosides and is therefore considered milder. The plant grows in a warmer, more stable climate, which means it needs to produce fewer secondary metabolites. This results in a gentler effect suitable for people who are sensitive to strongly stimulating herbs.

American ginseng (Panax quinquefolius) has a different ratio of ginsenosides, with relatively more compounds that have a calming effect on the central nervous system, the part of the nervous system consisting of the brain and spinal cord that is responsible for coordination and processing of stimuli. As a result, American ginseng is traditionally used to support mental clarity without strong stimulation.

Siberian ginseng, often referred to as Eleutherococcus senticosus, is strictly speaking not a true ginseng because it does not belong to the genus Panax. The plant contains no ginsenosides but eleutherosides, different bioactive compounds that mainly influence the stress response through the neuroendocrine system, the interplay between the nervous system and the hormonal system that regulates stress hormones. As a result, Siberian ginseng is traditionally used as an adaptogen, a remedy that helps the body cope better with physical and mental strain.

2.4 Red and White Ginseng

In trade and in medicine, a distinction is made between red and white ginseng, a difference that is not merely cosmetic but is directly tied to the chemical composition of the root. White ginseng is the root in its most natural form: after harvesting, it is cleaned, dried, and processed into powder. During this drying process, the original ginsenosides remain largely intact. Ginsenosides are bioactive compounds that affect the body through, among other things, the nervous system, which is responsible for processing stimuli and directing responses, and the immune system, which protects the body against pathogens. Because white ginseng retains these substances in their original form, it is often seen as milder and better suited for people who are sensitive to stimulating plant compounds.

Red ginseng undergoes an additional step: the root is steamed for several hours before being dried. This steaming process causes Maillard reactions, chemical reactions between sugars and amino acids that deepen the color and change the flavor. More importantly, this heating converts certain ginsenosides into new forms that the body can absorb more easily. This increased bioavailability, the capacity of a substance to actually enter the bloodstream and become active, explains why red ginseng is often considered more potent. The heat treatment also changes the ratio between stimulating and calming ginsenosides, which means red ginseng can have a more pronounced effect on energy metabolism and stress regulation. Stress regulation refers to the way the body, through the neuroendocrine system, in which the nervous system and hormonal system work together, keeps hormones such as cortisol in balance.

Both forms are used to support vitality and resistance, but the choice between red and white depends on sensitivity, desired intensity, and purpose of use. Red ginseng is often chosen when a stronger tonic effect is desired, while white ginseng remains suitable for long-term, mild support.

2.5 Ginseng in Holistic and Modern Medicine

In traditional Chinese medicine, ginseng has for centuries been regarded as a root that supports energy, resistance, and balance. In classical medicine, these three concepts form a coherent whole. Energy refers not only to physical strength but also to the body’s ability to keep internal processes stable, a principle known in modern biology as homeostasis. Homeostasis is the mechanism by which the body regulates temperature, hormones, blood pressure, and other vital functions within narrow limits. Ginseng was seen as a plant that strengthens this regulating capacity. In this context, the root is referred to as an adaptogen, a term used in modern pharmacology for substances that help the body adapt to stress and taxing circumstances. In a medical sense, stress refers to any stimulus that throws the body off balance, such as illness, fatigue, emotional pressure, or physical exertion. Adaptogens influence the way the neuroendocrine system responds to such stimuli. This system is the collaboration between the nervous system, which processes signals and directs responses, and the hormonal system, which produces hormones such as cortisol and adrenaline. Because of this regulating effect, ginseng was traditionally used for fatigue, recovery after illness, weakness, and general exhaustion. The root was seen as a tonic that strengthens life energy, or Qi. Qi is the concept in traditional medicine that refers to the vital force that supports all physical and mental functions. Although Qi has no direct modern equivalent, it can be compared to the entire set of physiological processes that contribute to vitality and resilience.

Historically, ginseng was highly prized in China and Korea; according to tradition, the root was sometimes even traded for gold. This high regard stemmed from the belief that ginseng not only relieved symptoms but strengthened the body as a whole. Wealthy families used ginseng to protect their health and extend their lifespan, in the belief that the root slowed the aging process. This idea aligns with modern insights about antioxidants, substances that neutralize free radicals. Free radicals are unstable molecules that can damage cells and contribute to aging and inflammation. Soldiers took ginseng to increase their strength, endurance, and recovery, which in modern terms can be explained by the influence of ginsenosides on metabolism. Metabolism encompasses all the processes by which the body produces, stores, and uses energy. By making these processes more efficient, ginseng may contribute to faster recovery after physical exertion.

In Ayurvedic medicine, the traditional medical system of India, a root with a similar reputation is also used to support vitality and resistance. This is generally not Panax ginseng itself but ashwagandha (Withania somnifera), a botanically different plant that is popularly also known as Indian ginseng. Ayurveda regards such roots as rasayana, remedies that rejuvenate and strengthen the body. Although the plant species differs, the underlying idea is similar: both roots are used to support the body’s ability to recover and maintain balance.

In modern medicine and pharmacology, ginseng has become the subject of extensive research. Scientists have identified a large number of bioactive substances in the root, of which ginsenosides are the most important. Ginsenosides are saponins, a group of compounds that can have wide-ranging effects in the body. They are associated with anti-inflammatory activity because they influence certain signaling pathways involved in inflammation. Inflammation is the medical term for the body’s response to damage or infection. When this response is too strong or too prolonged, it can become harmful. Ginsenosides can modulate these processes, meaning they can influence the intensity of the inflammatory response. In addition, they have antioxidant properties, meaning they neutralize free radicals and help prevent cellular damage. Ginsenosides are also described as immunomodulating, meaning they can strengthen or dampen the immune system depending on what is needed. The immune system is the body’s defense mechanism, which recognizes and fights pathogens. Because of this versatile activity, ginsenosides are seen as the core of ginseng’s medicinal value.

Today, ginseng is used in dietary supplements, capsules, powders, beverages, and extracts. The popularity of these forms is tied to the need for standardized dosing, since the concentration of ginsenosides in natural roots can vary widely. In addition, ginseng is a popular ingredient in skincare products, particularly anti-aging creams. The antioxidant properties of ginsenosides can protect the skin against oxidative stress, a process in which free radicals damage skin cells and contribute to wrinkle formation and loss of elasticity. Because of this protective effect, ginseng is used to strengthen the skin barrier and slow signs of aging. Ginseng is also used in sports nutrition, for example in energy drinks and bars, because the plant can support energy metabolism and promote recovery after exertion. This effect is attributed to the influence of ginsenosides on mitochondria, the energy factories of the cell, which are responsible for producing ATP, the body’s main energy source.

Development in this field continues. Researchers are working on methods to isolate and standardize specific ginsenosides, so that preparations can be targeted for specific purposes such as memory, energy, or stress resilience. Memory depends on processes in the hippocampus, a brain region involved in learning and remembering. Some ginsenosides appear to support these processes by improving communication between nerve cells. Stress resilience is tied to the regulation of cortisol, a hormone produced by the adrenal glands in response to stress. By stabilizing cortisol levels, ginseng may contribute to a more balanced stress response. Fermentation techniques are being studied to improve ginseng’s absorbability. Absorbability, or bioavailability, refers to the extent to which a substance actually enters the bloodstream and becomes active in the body. Fermentation can convert ginsenosides into forms that are more easily absorbed, increasing the effectiveness of ginseng preparations.

There is also growing interest in ginseng’s potential neuroprotective effects in conditions such as Alzheimer’s and Parkinson’s disease. Neuroprotection refers to the ability to protect nerve cells from damage or degeneration. In Alzheimer’s disease, the buildup of harmful proteins and inflammatory processes play a role, while in Parkinson’s disease, the loss of dopamine-producing cells is central. Ginsenosides appear to influence certain signaling pathways involved in cell protection, inflammation reduction, and repair of nerve tissue. Ginseng is also being studied in cancer research, examining effects on tumor growth, immune function, and protection against free radicals. Tumor growth is influenced by processes such as angiogenesis, the formation of new blood vessels that supply tumors with nutrients. Some ginsenosides appear able to inhibit these processes, while others support the immune system in recognizing and fighting abnormal cells.

2.6 Ingredients, Effects, and Dosage

Ginseng is known as a medicinal plant because of the unique composition of the root, which forms a complex whole of bioactive substances that reinforce one another. The main active compounds are the ginsenosides, of which more than fifty different types have now been identified in ginseng. Ginsenosides belong to the saponins, soap-like molecules that foam in water because they contain both water-attracting and fat-attracting parts. This structure allows them to bind to cell membranes and influence biological processes there. The fact that ginsenosides occur exclusively in ginseng makes the plant pharmacologically unique. The plant produces these substances as part of its secondary metabolism, a process in which plants create compounds to protect themselves against stress, cold, insects, and fungi. Secondary metabolites are not direct building blocks of the plant but serve as a defense mechanism. This protective function explains why they often have a regulating or strengthening effect in the human body. Older ginseng plants’ secondary roots in particular contain high concentrations of ginsenosides, because these roots have been exposed to environmental stress for years and have therefore built up more protective substances. This makes older roots more valuable in both traditional and modern medicine.

In addition to ginsenosides, ginseng contains a large number of other components that contribute to the plant’s broad range of action. These substances include minerals such as magnesium, calcium, sodium, manganese, selenium, and iron. Magnesium plays a crucial role in muscle function and the nervous system because it is involved in transmitting electrical signals between nerve cells. Calcium is essential for bone structure and for muscle contraction, while sodium plays a key role in fluid balance and nerve signal transmission. Manganese and selenium function as cofactors for enzymes involved in antioxidant processes, in which harmful free radicals are neutralized. Free radicals are unstable molecules that can damage cells and contribute to aging and inflammation. Iron is necessary for the formation of hemoglobin, the protein in red blood cells that transports oxygen. In addition, ginseng contains B vitamins, which play a role in energy production and nervous system function, as well as essential oils and amino acids that contribute to overall vitality. Potassium, which is also present in ginseng, is important for cell growth and hormonal balance regulation, because it is involved in the electrical activity of cells and the release of hormones. This broad composition explains why ginseng has a tonic effect, a term referring to a remedy’s ability to strengthen and support the body as a whole.

The healing and supportive effect of ginseng root has been demonstrated in various studies. The plant can be used to support the cardiovascular system, because certain ginsenosides affect the elasticity of blood vessels and can improve circulation. The cardiovascular system consists of the heart and blood vessels and is responsible for transporting oxygen and nutrients throughout the body. By promoting blood circulation, ginseng may contribute to better oxygen supply to tissues. In addition, ginseng can strengthen the immune system because ginsenosides affect the activity of immune cells such as macrophages and natural killer cells. Macrophages are cells that detect and clear pathogens, while natural killer cells are involved in destroying infected or abnormal cells. Through this immune-modulating effect, ginseng can help make the body more resistant to infections.

Ginseng also has a stabilizing effect on the nervous system, which is responsible for processing stimuli and directing responses. This stabilizing effect is attributed to the influence of ginsenosides on neurotransmitters, the chemical messengers nerve cells use to communicate with one another. By supporting the balance between stimulating and inhibiting neurotransmitters, ginseng can help the nervous system process stimuli more effectively. In addition, there are indications that ginseng may help lower blood sugar levels. This effect is explained by the influence of ginsenosides on insulin sensitivity. Insulin is a hormone produced by the pancreas that allows glucose to move from the blood into cells. When cells become more sensitive to insulin, blood sugar levels can be better regulated. This makes ginseng relevant for people with fluctuating glucose levels.

There are also indications of a positive effect on potency. This is attributed to the influence of ginsenosides on nitric oxide production in blood vessels. Nitric oxide is a signaling molecule that relaxes the vessel wall, improving blood flow to certain tissues. Better blood flow may contribute to improved erectile function. Although the results are promising, further research is needed to fully confirm effectiveness.

Ginseng is not a remedy with immediately noticeable effects. Its action builds up gradually, because the ginsenosides need time to distribute through the body and exert their regulating effect. For this reason, long-term use is often recommended. Ginseng powder is usually offered in capsule form, at various concentrations. In general, a daily intake of one to two grams of ginseng is cited as sufficient to gain its benefits. This dosage is based on studies in which this amount proved sufficient to achieve physiological effects without unwanted side effects. Fresh root can also be used, for example in vegetable and fruit juices or as a base for tea. Some people chew on pieces of fresh root, since this allows for direct absorption of certain substances through the oral mucosa. In addition, ginseng is used in creams, shampoos, body oils, and oral care products. These products make use of the antioxidant and anti-inflammatory properties of ginsenosides, which can protect the skin from damage caused by free radicals and help support a healthy skin barrier.

Ginseng’s versatility comes from the complex interaction between the many bioactive substances in the root. The combination of ginsenosides, minerals, vitamins, and amino acids creates a synergistic effect, in which the substances reinforce one another. This explains why ginseng is regarded, in both traditional and modern medicine, as a plant with a broad range of action. The root does not support just one organ or system but influences multiple processes at once, from energy production to immune function and from nerve signaling to hormonal regulation. This versatility makes ginseng one of the most researched and highly regarded plants within phytotherapy, the science concerned with the medicinal effects of plants.

2.7 Indications and Everyday Uses

Ginseng is used for a wide range of complaints and situations, and the reason the root is so broadly applicable lies in the combination of bioactive substances that influence multiple physiological systems at once. The root is used for blood pressure fluctuations, because certain ginsenosides can affect the elasticity of blood vessels. Blood pressure is regulated by the tension in the vessel wall and the amount of blood the heart pumps. When ginseng relaxes the vessel wall, this can contribute to more stable blood pressure. In cases of exhaustion and severe fatigue, ginseng’s influence on energy metabolism plays a role. Energy metabolism encompasses all the processes by which the body converts nutrients into usable energy. By supporting the activity of mitochondria, the energy factories of the cell, ginseng may contribute to improved endurance and faster recovery.

For general malaise and reduced endurance, ginseng is used for its tonic effect, a term referring to a remedy’s ability to strengthen the body as a whole. This effect comes from the combination of ginsenosides, vitamins, and minerals that together support resistance and vitality.

Ginseng is also used for erectile dysfunction, although the evidence for this is limited. The possible effect is attributed to the influence of ginsenosides on the production of nitric oxide, a signaling molecule that relaxes blood vessels and improves circulation. Better blood flow may contribute to improved erectile function, but because the studies are not consistent, caution is warranted in drawing medical conclusions.

Ginseng is also used to support more stable blood sugar levels. This effect is linked to the influence of ginsenosides on insulin sensitivity. Insulin is a hormone that allows glucose to move from the blood into cells. When cells become more sensitive to insulin, blood sugar levels can be better regulated. This makes ginseng relevant for people with fluctuating glucose levels.

Ginseng is also used for stress and nervousness, because the root affects the neuroendocrine system, the interplay between the nervous system and the hormonal system that determines how the body responds to stressors. Stressors are stimuli that place a burden on the body, such as illness, emotional pressure, or intense exertion. By regulating the production of stress hormones such as cortisol, ginseng may contribute to a more balanced stress response.

For concentration problems and mental fatigue, ginseng’s influence on neurotransmitters plays a role. Neurotransmitters are chemical messengers that nerve cells use to communicate with one another. By supporting the balance between stimulating and inhibiting neurotransmitters, ginseng may contribute to better mental clarity and cognitive function. Cognition includes processes such as thinking, learning, remembering, and decision-making.

During menopause, ginseng is used to help offset hormonal fluctuations. Menopause is accompanied by changes in the production of estrogen and progesterone, hormones that affect mood, energy, and temperature regulation. By supporting hormonal balance, ginseng may contribute to more stable well-being.

Ginseng is also used to improve general resistance to illness, because the root can affect the activity of immune cells. The immune system is the body’s defense mechanism, which recognizes and fights pathogens. By stimulating the activity of macrophages and natural killer cells, ginseng may contribute to better defenses.

For certain skin conditions, ginseng is used for its antioxidant and anti-inflammatory properties. Antioxidants neutralize free radicals, unstable molecules that can damage cells and contribute to inflammation and aging. By regulating these processes, ginseng may help support the skin barrier.

Ginseng also plays a role in digestion, because the root affects intestinal motility, the movement of the intestines needed for healthy digestion.

Ginseng can be incorporated into daily life in various ways. Some people choose traditional ginseng tea, where the heat helps release the active substances. Others prefer capsules or powder that can easily be added to a smoothie or juice. During periods of increased strain, such as stressful work phases or recovery from illness, ginseng is often used for extra support.

At the same time, it is important to recognize that ginseng is a powerful remedy and that excessive use can lead to side effects. Because ginseng affects hormones, blood pressure, and the nervous system, it is advisable to consult a doctor or specialist when in doubt, especially with long-term use or existing health conditions.

3. Health Benefits

3.1 Stabilization of Blood Pressure and Blood Sugar Levels

Ginseng can play a supportive role in regulating blood pressure and blood sugar levels. Blood pressure is determined by the force with which the heart pumps blood and by the tension in the vessel wall. When blood vessels relax, resistance decreases and blood pressure drops. Ginsenosides influence the production of nitric oxide, a signaling molecule that relaxes the vessel wall. This relaxation improves blood circulation and evens out blood pressure fluctuations. This eases the burden on the cardiovascular system, which consists of the heart and blood vessels and is responsible for transporting oxygen and nutrients.

In addition, ginseng plays a role in regulating blood sugar levels. Blood sugar levels are controlled by insulin, a hormone produced by the pancreas that allows glucose to move from the blood into cells. When cells become less sensitive to insulin, insulin resistance develops, a condition that can lead to elevated glucose levels. Ginsenosides can improve insulin sensitivity by influencing the cellular signaling pathways involved in glucose uptake. As a result, ginseng may contribute to more stable glucose regulation, which is especially relevant for people with fluctuating blood sugar levels or an increased risk of type 2 diabetes.

3.2 Support During Hormonal Transition Phases

During menopause, hormonal fluctuations can lead to a range of complaints, such as mood swings, hot flashes, and fatigue. These complaints arise because the production of estrogen and progesterone declines. Estrogen and progesterone are hormones that play an important role in regulating mood, temperature, energy level, and sleep. When hormone levels fluctuate, the neuroendocrine system becomes unbalanced, which can lead to physical and emotional instability.

Ginseng can help the body better absorb these hormonal changes because ginsenosides influence hormone receptors in the body. Hormone receptors are proteins on cells that respond to hormones and transmit signals. By modulating these receptors, ginseng may contribute to a more stable hormonal balance. In addition, ginseng supports the regulation of cortisol, the stress hormone that is often elevated during menopause. By stabilizing cortisol levels, ginseng may contribute to a more stable energy level and better emotional balance. This explains why ginseng is often used by women seeking support during this stage of life.

3.3 Oxidative Protection and Slowing of Aging

Another important benefit of ginseng is protection against free radicals. Free radicals are unstable molecules that form during normal metabolic processes or as a result of external factors such as air pollution, UV radiation, and stress. Because free radicals are missing electrons, they react readily with cells and tissues, which can lead to oxidative stress. Oxidative stress is a state in which the amount of free radicals exceeds the body’s capacity to neutralize them. This process plays an important role in aging and in the development of chronic disease.

Ginseng contains antioxidants, substances that neutralize free radicals by donating electrons without becoming unstable themselves. Ginsenosides have an antioxidant effect because they stimulate the activity of antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase. These enzymes form a line of defense against oxidative damage. Through this action, ginseng may contribute to slowing aging processes, protecting cells, and maintaining good overall health. These antioxidant properties also explain why ginseng is often used in skincare products, where it can strengthen the skin barrier and reduce signs of aging.

3.4 Calming Effect on the Nervous System

An important health benefit of ginseng is its calming effect on the central nervous system. The central nervous system consists of the brain and spinal cord and forms the body’s control center, where all stimuli are processed and responses are directed. When someone is exposed to stressors, such as emotional pressure, illness, or overexertion, the body activates the stress response. This response is regulated by the neuroendocrine system, the interplay between the nervous system and the hormonal system that produces hormones such as cortisol. Cortisol is a stress hormone that helps the body stay alert, but when chronically elevated, it can lead to overstimulation, fatigue, and mood complaints.

Ginsenosides, the main bioactive substances in ginseng, influence signal transmission between nerve cells. They modulate neurotransmitters, the chemical messengers nerve cells use to communicate with one another. By supporting the balance between stimulating neurotransmitters such as glutamate and inhibiting neurotransmitters such as GABA, ginseng helps the nervous system process stimuli more effectively. This explains why users tend to feel less easily overstimulated and can better cope with emotional and mental strain. This regulating influence on the nervous system contributes to a more stable sense of well-being, because the body reacts less intensely to stress and returns more quickly to a state of rest.

3.5 Help With Erectile Dysfunction

Ginseng is sometimes used by men with erectile dysfunction, a condition in which it is difficult to achieve or maintain an erection. An erection occurs when the blood vessels in the penis relax and fill with blood. This process is regulated by nitric oxide, a signaling molecule that relaxes the vessel wall. Some ginsenosides appear to stimulate nitric oxide production, which can improve blood flow.

Although some studies show a mild to moderate positive effect, as of 2025 there is still insufficient convincing evidence to consider ginseng an effective and reliable treatment for erectile dysfunction. Study results are inconsistent, and the mechanism of action is not fully understood. For erectile problems, it is therefore advisable to consult a physician for appropriate treatment, since erectile dysfunction can also be a symptom of underlying conditions such as cardiovascular disease or diabetes.

3.6 More Energy and Improved Mental Function

Ginseng is known for its ability to support both physical and mental energy. Physical energy is determined by the efficiency of energy metabolism, the process by which cells convert nutrients into ATP, the body’s main energy source. Mitochondria, the energy factories of the cell, play a central role in this process. Ginsenosides can stimulate mitochondrial activity, increasing energy production. This explains why ginseng is used by people who feel weak, exhausted, or chronically tired.

Ginseng also has a supportive effect on cognitive function. Cognitive functions include processes such as concentration, memory, information processing, and mental clarity. These functions depend on effective communication between nerve cells, which occurs through neurotransmitters. Ginsenosides influence the release and uptake of neurotransmitters such as dopamine, serotonin, and acetylcholine. Dopamine plays a role in motivation and attention, serotonin in mood and emotional stability, and acetylcholine in memory and learning processes. By bringing these neurotransmitters into balance, ginseng may contribute to improved cognitive performance. This makes the root appealing to both older adults and people under heavy mental strain from work or study.

3.7 Anti-Inflammatory Effects

The ginsenosides in Panax ginseng have anti-inflammatory properties. Inflammation is a natural response of the immune system to damage, infection, or irritation. In acute inflammation, this response is beneficial because it helps fight pathogens and repair damaged tissue. When inflammation becomes chronic, however, it can contribute to the development of conditions such as arthritis, cardiovascular disease, and autoimmune disorders.

Ginsenosides influence inflammatory processes by regulating the activity of cytokines. Cytokines are signaling molecules that immune cells use to communicate with one another. Some cytokines promote inflammation, while others suppress it. By influencing the balance between these cytokines, ginseng may help reduce excessive inflammatory responses. This explains why ginseng is often mentioned in the context of chronic inflammatory complaints and why the root is being studied as possible support for conditions in which inflammation plays a central role.

4. Risks and Side Effects

Although ginseng has many potential benefits, it is important to also consider its risks and possible side effects, precisely because the root contains powerful bioactive substances that influence multiple physiological systems at once. With oral use of Panax ginseng for longer than six months, hormone-like effects can occur. These effects arise because certain ginsenosides can bind to hormone receptors, proteins on cells that normally respond to the body’s own hormones such as estrogen and cortisol. When these receptors are activated by plant compounds, the body may receive signals resembling hormonal stimuli, which with prolonged exposure can disrupt the body’s natural hormonal balance. This explains why long-term use calls for caution.

The most common side effect is insomnia. Insomnia occurs when the central nervous system remains too active, making it difficult to fall asleep or stay asleep. The central nervous system consists of the brain and spinal cord and governs all stimulus processing. Because ginseng has a mildly stimulating effect in some people, especially when taken late in the day, it can influence the release of neurotransmitters. Neurotransmitters are chemical messengers that nerve cells use to transmit signals. When stimulating neurotransmitters such as dopamine or norepinephrine remain elevated, this can lead to heightened alertness that disrupts sleep.

Less commonly, other complaints occur, such as menstrual problems, chest pain, an increased or decreased heart rate, high or low blood pressure, headache, loss of appetite, diarrhea, itching, skin rash, dizziness, mood swings, and vaginal bleeding. These complaints are generally rare but deserve attention because they point to ginseng’s influence on the cardiovascular system, the immune system, and the neuroendocrine system. The cardiovascular system consists of the heart and blood vessels and responds sensitively to substances that relax or tighten the vessel wall. The immune system, responsible for defense against pathogens, can respond to ginsenosides because they affect the activity of immune cells. The neuroendocrine system, the collaboration between the nervous system and the hormonal system, can become dysregulated when plant compounds affect hormone release or the stress response. These systems are closely interconnected, so a disruption in one system can cause complaints in another.

In rare cases, more serious side effects have been reported, such as severe skin rash, Stevens-Johnson syndrome, liver damage, and severe allergic reactions. Stevens-Johnson syndrome is a rare but serious immune reaction in which the skin and mucous membranes become inflamed and form blisters. Liver damage can occur when the liver, the organ responsible for breaking down substances, becomes overloaded by bioactive compounds that are difficult to metabolize. Severe allergic reactions can occur when the immune system reacts excessively to a component of the plant and releases substances such as histamine, which can lead to swelling, breathing difficulties, or skin reactions. Although these reactions are extremely rare, they underscore that ginseng, despite its natural origin, is a powerful substance that should not be used without limits or without careful consideration.

If unusual or severe complaints occur, it is advisable to stop use and seek medical advice. This is especially important because some side effects may indicate underlying sensitivities or interactions with other substances. Ginseng, for example, can affect how certain medications work because ginsenosides alter the activity of liver enzymes responsible for breaking down drugs. Liver enzymes are proteins that speed up chemical reactions and determine how quickly substances are processed. When these enzymes are inhibited or stimulated, the concentration of medications in the blood can change, which can lead to unwanted effects.

It is therefore wise to approach ginseng with the same care as any other powerful therapeutic remedy. The root has a broad range of action and can offer valuable support, but it calls for responsible use, especially with prolonged intake, high doses, or existing health conditions.

As a Final Note

Ginseng occupies a unique place at the intersection of traditional wisdom and modern scientific insight. Thanks to its broad spectrum of bioactive substances, it can influence multiple physiological systems at once, from energy metabolism and cognitive function to hormonal balance, immune activity, and cardiovascular health. This versatility explains why ginseng has been valued for centuries and why it continues to attract scientific interest today.

At the same time, this powerful action calls for thoughtful and responsible use. The same mechanisms that make ginseng effective, such as its impact on neurotransmitters, hormones, immune cells, and metabolic processes, also mean it can cause side effects or interact with medications. For most people, ginseng can be a valuable addition to a daily health routine, whether for energy, resilience, or overall well-being, but it should be approached with awareness and respect for its potency.

As research advances, our understanding of ginseng’s mechanisms and applications will continue to deepen. What remains clear is that this ancient root offers more than a single benefit: it supports the body as an integrated whole. When used wisely, ginseng can be a valuable ally in maintaining balance, vitality, and health over the long term.
