Ginseng Benefits: Uses, Dosage, and Precautions

Dr. Boris Wydoff

Ginseng is a perennial medicinal plant best known for its tonic and restorative properties. According to herbal medicine reference books, preparations made from its root stimulate the central nervous system, improve performance, and help the body cope more easily with physical and mental stress. Traditionally, ginseng has been used for weakness and exhaustion. So, when we talk about the benefits of ginseng, we are primarily referring to its tonic and adaptogenic properties.

What Is Ginseng, What Does It Contain, and How Can You Identify It?

Ginseng is one of the plants that have been used in medicine for a long time. Its scientific name is Panax ginseng. In reference books, the root is listed as Radix Ginseng. The root is considered the plant's main medicinal part.

In the wild, ginseng became widely known in the Russian Far East. According to reference books, it grows in Primorsky Krai, Sakhalin, and the Kuril Islands. The plant gained worldwide recognition as a representative of the medicinal flora of the Far East.

History of Ginseng Research

Ginseng has been used in medicine for centuries. However, the plant's long history does not mean that all its properties have been studied equally well. According to pharmacological reference books, detailed research into different medicinal forms of ginseng began relatively late. Most of these studies were conducted in recent decades, primarily on laboratory animals.

Research into ginseng also sparked interest in other plants from the Araliaceae family. Researchers examined their chemical composition and botanical relationships, which led to the study of new members of this group, some of which eventually became part of medical practice.

In medical literature, ginseng is often mentioned alongside eleuthero, aralia, and devil's club. What these plants have in common is their traditional use as remedies that support overall vitality. However, preparations made from different plants have their own characteristics and are not fully interchangeable.

How to Identify Quality Raw Material

Ginseng root is especially highly valued. In traditional herbal reference books, the quality of the raw material is considered very important. One reference book specifically notes that high-quality plants should be selected for use, particularly Korean preparations.

When choosing ginseng, it is important to consider not only its origin but also the condition of the root. Guidelines for harvesting wild ginseng include a separate classification of root damage. This makes it possible to assess root quality and determine its purchase price.

The root's appearance does not always make it possible to reliably establish its origin or medicinal quality. In addition, similarities between the shapes of roots from different plants can be misleading. That is why, when buying ginseng, you should look for labeling and documents confirming the species and origin of the raw material rather than relying on appearance alone.

Ginseng appears in medicinal reference books for good reason. Its preparations have been studied in considerable detail. At the same time, pharmacological research into different forms of ginseng has mainly been conducted over the past few decades, including studies on laboratory animals.

For me, one simple principle matters here. Ginseng should not be treated as a universal remedy for every problem. Its traditional use is primarily associated with its tonic effects and support for physical and mental performance.

What Are the Benefits of Ginseng for the Nervous System?

According to herbal medicine reference books, one of ginseng's main characteristics is its effect on the central nervous system. Studies of root preparations have reported increased excitatory activity in neurons of the cerebral cortex and brainstem.

Its effects depend on the dose. At low doses, ginseng preparations increased excitatory processes and reduced inhibitory processes. At high doses, the opposite pattern was observed: inhibitory processes became stronger.

This is an important observation. It shows that the amount taken matters. That is why you should not exceed the recommended dose.

Animal experiments have shown that ginseng preparations improve performance and reduce fatigue during significant physical and stressful exertion. A pronounced adaptogenic effect has also been described. In reference books, this means the body's ability to adapt better to unfavorable conditions.

Ginseng preparations have traditionally been used as tonic and restorative remedies. Medical reference books describe their use for weakness and prolonged physical and mental exhaustion.

How Does Ginseng Affect Performance and Overall Vitality?

Ginseng is often associated with supporting overall vitality. According to reference books, root preparations have been used to improve performance and help the body resist stressful situations and unfavorable external influences.

Its use has also been described during recovery after serious illnesses, complex surgical procedures, and prolonged complications. Ginseng has also been used for prolonged physical and mental exhaustion.

Medical observations cited in a reference book report that, after taking ginseng tincture, patients experienced improvements in their general condition, fewer complaints of sluggishness and rapid fatigue, better appetite, and increased overall vitality.

However, this information does not mean that ginseng replaces medical treatment. When someone has an illness or significant weakness, a doctor needs to determine the underlying cause.

Ginseng has also been described as having seasonal effects. One reference book states that taking it in autumn and winter was considered most effective. Smaller doses were recommended during other seasons.

Seasonal Use and Adaptogenic Effects

Traditional ginseng regimens took the time of year into account. Autumn and winter were considered the most suitable seasons for taking root preparations, while lower doses were recommended in spring and summer. This recommendation appears in older reference literature and does not replace current instructions for medicinal products.

Ginseng's adaptogenic effects were also considered in relation to how the body responds to physical and mental stress. In experiments, root preparations increased animals' resistance to stressful conditions and helped them maintain performance when fatigued.

However, an adaptogenic effect should not be understood as protection against every unfavorable condition. It describes the results of specific observations and experiments, not a guaranteed effect of everyday use.

What Is Known About Ginseng's Effects on Other Body Systems?

Reference books describe ginseng's pharmacological effects as broad. Experiments have reported improved blood supply to the brains of cats due to dilation of the pineal vessels, as well as increased oxygen consumption in animals.

Effects on the cardiovascular system have also been described. These effects were not straightforward and depended on the dose. At low doses, ginseng slightly increased blood pressure in different animal species, while at high doses it could lower it.

The preparations were also found to increase the amplitude of heart contractions and slow the heart rate. These findings come from experiments and should not be directly applied to humans as medical recommendations.

Reference books also describe the effects of ginseng preparations on metabolic processes in liver and bone marrow cells. Experiments reported changes in DNA, protein, RNA, and lipid synthesis, as well as effects on certain hormonal and neurotransmitter processes.

The plant's anti-stress properties and its ability to increase animals' resistance to certain unfavorable conditions are also described. There is evidence of increased blood cell production and changes in other physiological processes.

Effects on Metabolic Processes

Experimental studies of ginseng preparations have examined not only the responses of the nervous and cardiovascular systems but also changes in cellular metabolism. In particular, researchers have described increased DNA, RNA, and protein synthesis in bone marrow cells, as well as changes in the activity of enzymes involved in metabolic processes.

Researchers have also noted changes in the levels of certain biologically active substances in the adrenal glands and brains of laboratory animals. Specifically, changes in dopamine, norepinephrine, and serotonin levels were recorded.

Experiments have also found anti-inflammatory effects of ginseng preparations, as well as faster wound healing in animals. However, these results alone do not prove that ginseng root is effective in treating inflammatory diseases or tissue injuries in humans.

This information helps explain why ginseng is classified as a tonic plant. But experimental findings do not provide an independent basis for treating any particular disease.

What Conditions Is Ginseng Used For According to Reference Books?

According to herbal medicine reference books, ginseng preparations have been used as tonic and restorative remedies. The conditions for which this use is described include asthenic states, physical and mental exhaustion, and recovery after serious illnesses and surgery.

Medical literature also describes its use for certain neurotic conditions, insomnia, and reduced overall vitality. Its use for impotence is mentioned separately. There are also more specialized medical applications. For example, ginseng preparations are listed among general tonic remedies for the hypokinetic form of biliary dyskinesia. However, it is especially important here to distinguish traditional use from self-treatment. If you have a diagnosis or persistent symptoms, you should first have a medical examination.

Use During Recovery

Older medical reference books list ginseng among the remedies prescribed during convalescence, meaning recovery after serious illnesses. It was also included in some treatment plans to support patients after complex surgical procedures and during prolonged complications.

Some medical observations reported improvements in appetite, general well-being, and performance indicators in patients taking root preparations. Certain authors described an easier postoperative recovery when ginseng was used as part of a comprehensive preparation plan.

This information relates to specific medical observations and historical treatment approaches. It does not mean that everyone needs ginseng after surgery or a serious illness. The decision to use it during recovery should be made by the treating physician, taking the patient's condition and medications into account.

How Should You Take Ginseng and Its Preparations?

The reference book describes ginseng root for oral use in the form of an alcohol-based tincture or tablets. The tincture is prescribed before meals at a dose of 15–25 drops 3 times a day. The tablet form is prescribed at 0.15–0.3 g 3 times a day. The stated treatment course is 2–4 weeks.

Another medical regimen uses ginseng tincture at a dose of 20 drops 3 times a day, 30 minutes before meals. These regimens come from specific medicinal prescriptions in reference literature.

That is why you should not increase the dose based on the idea that "more means stronger." This is particularly important with ginseng because reference books describe dose-dependent effects. According to the reference book, taking it in the recommended amounts was generally not associated with side effects. However, nausea, vomiting, headaches, and increased blood pressure were sometimes reported.

Medicinal Forms of Ginseng

Several forms of ginseng root preparations are described in medical practice. These include alcohol-based tinctures, tablets, and liquid extracts. The range of available products may vary from country to country.

A tincture is a liquid preparation whose dose is measured in drops. Tablets make it possible to measure the amount of active raw material according to the prescribed dose. Liquid extract is also a ready-made medicinal form, but its concentration and method of use depend on the specific product.

When choosing a medicinal form, it is important to follow the manufacturer's instructions. Even if two products are made from the same plant, their concentrations and dosages may differ. That is why you should not transfer a dosing schedule from a tincture to an extract or tablets without checking the instructions.

Can You Make Ginseng Tea or an Infusion?

Ginseng has traditionally been used in medicinal forms, primarily as a tincture and in tablets. Reference literature also describes ginseng as a tonic plant, but the recipes provided do not specify exact proportions for homemade tea, infusions, or decoctions.

When using a medicinal plant, it is better to follow the dosage of a ready-made preparation and its instructions. This is especially important because ginseng has been described as having dose-dependent effects on the nervous and cardiovascular systems. Increasing the amount of root in a homemade preparation may change the expected effect.

How Is This Plant Harvested and Stored?

Reference literature focuses primarily on the quality of the root. High-quality raw material is valued for medicinal use, and wild ginseng is considered separately.

Guidelines for harvesting describe requirements for wild ginseng and the types of damage that may affect its roots. If natural or artificial damage was present, the purchase price of the raw material was reduced by 10% for first-category damage and by 20% for second-category damage.

Damage categories for wild ginseng roots were defined by GOST 10064-62.

Assessing Root Damage During Harvesting

Historical purchasing regulations for wild ginseng assessed the condition of the roots separately from their origin. Natural or artificial damage could affect the value of the raw material. A 10% reduction in the purchase price was provided for first-category damage and a 20% reduction for second-category damage.

The categories were determined in accordance with GOST 10064-62. This classification was part of the system for assessing harvested raw material, not a recommendation for independently determining whether it was suitable for medicinal use.

Damage matters for more than just the root's appearance. It can make it harder to assess its condition and quality. That is why, for medicinal use, it is preferable to choose raw material with confirmed origin and appropriate labeling.

For home use, this is another reminder of the importance of raw material quality. The root must be intended specifically for medicinal use. You should not use an unidentified plant simply because someone calls it ginseng.

Ready-made preparations have a clearer medicinal form and a specified dosage. When choosing them, it is important to follow the manufacturer's instructions and not exceed the recommended amount.

How to Find Ginseng Abroad

If you live in the United States or Europe, you can find ginseng in pharmacies, health food stores, and specialty tea shops. When buying it, pay attention to the plant's name and the part used to make the product.

• USA: look for Asian ginseng, Korean ginseng, or *Panax ginseng*. These products are sold in pharmacies, health food stores, and online.
• Germany: use the names Ginseng, Ginsengwurzel, or Koreanischer Ginseng. Look for the plant in pharmacies (Apotheke), Reformhaus stores, tea shops, and online.
• France: look for ginseng, ginseng asiatique, ginseng coréen, or racine de ginseng. Ginseng is sold in pharmacies (pharmacie), health food stores, tea shops, and online.

Ginseng is available in several forms:

• whole or sliced dried root;
• ground root for brewing and tea bags;
• tinctures and liquid extracts;
• capsules containing root powder or extract.

White and red ginseng are different ways of processing the root.

What to check on the packaging:

• the Latin name *Panax ginseng* and an indication that the product contains the root (radix, Wurzel, or racine);
• the ingredients and product form;
• proof of organic certification, if the product is labeled organic or bio.

Do not confuse Asian ginseng with American ginseng (*Panax quinquefolius*) or so-called Siberian ginseng (*Eleutherococcus senticosus*). In Germany, medicinal tea (Arzneitee) is also distinguished from ordinary food-grade tea (Lebensmitteltee). In the United States, dietary supplements do not undergo FDA premarket approval before being sold. Each country has its own rules for labeling and selling these products.

What Should You Know About Contraindications?

Current evidence suggests that short-term oral use of ginseng in recommended amounts is generally considered safe for most adults. However, the safety of long-term use has been studied less thoroughly. Ginseng should not be used by anyone with an allergy to it. Caution is needed in people with autoimmune diseases or blood clotting disorders. A doctor should be consulted before use in these situations.

Ginseng may interact with medications. It is particularly important to discuss its use with your doctor if you take anticoagulants or antiplatelet drugs, including warfarin. Evidence about ginseng's effects on anticoagulants remains mixed.

It may also enhance the effects of insulin and sulfonylurea medications, which lower blood sugar levels. Possible interactions have also been reported with MAO inhibitors, including phenelzine, as well as imatinib and raltegravir. For many of these interactions, there is still insufficient evidence.

Before surgery, tell your doctor that you are taking ginseng. MSKCC recommends stopping its use at least one week before a surgical procedure.

Ginseng should not be used during pregnancy or breastfeeding. There is not enough safety data. The EMA does not recommend ginseng root preparations for children under 18 because of insufficient safety information.

The most common side effect is considered to be insomnia. Other possible effects include stomach upset, nausea, vomiting, diarrhea or constipation, itching, hives, nervousness, and a rapid heartbeat.

Severe allergic reactions, pronounced skin rashes, and liver damage have rarely been reported. Improper or excessive use has also been associated with increased blood pressure, insomnia, diarrhea, chest pain, rashes, and confusion.

A toxic dose of ginseng has not been clearly established. That is why you should not exceed the recommended dose of a preparation. The reference book describes signs of intoxication, including a rash, dizziness, headache, and increased blood pressure, after oral intake of 200 ml of tincture or an entire medium-sized root.

When Should You See a Doctor?

If you develop an allergic reaction, a pronounced rash, severe palpitations, vomiting, a headache, or other unusual symptoms after taking ginseng, stop using it and seek medical attention.

During pregnancy and breastfeeding, the decision about using ginseng should be made by a doctor. Children should not use ginseng root preparations without medical advice. If you take medication regularly, especially medicines that affect blood clotting or blood sugar levels, discuss possible interactions with a specialist in advance. People with chronic conditions should also consult a doctor. Ginseng does not replace diagnosis or prescribed treatment.
