Asian ginseng is native to China and Korea and has been used in various systems of medicine for many centuries. Asian ginseng is one of several types of true ginseng (another is American ginseng, Panax quinquefolius). An herb called Siberian ginseng or eleuthero (Eleutherococcus senticosus) is not a true ginseng.
Treatment claims for Asian ginseng are numerous and include the use of the herb to support overall health and boost the immune system. Traditional and folk uses of ginseng include:
- Improving the health of people recovering from illness
- Increasing a sense of well-being and stamina, and improving both mental and physical performance
The root of Asian ginseng contains active chemical components called ginsenosides (or panaxosides) that are thought to be responsible for the herb’s medicinal properties.
The root is dried and used to make tablets or capsules, extracts, and teas, as well as creams or other preparations for external use.
- Other studies indicate possible beneficial effects on immune function.
- Although Asian ginseng has been widely studied for a variety of uses, research results to date do not conclusively support health claims associated with the herb. Only a few large, high-quality clinical trials have been conducted. Most evidence is preliminary—i.e., based on laboratory research or small clinical trials.
- NCCAM supports studies to better understand the use of Asian ginseng.
- Short-term use of ginseng at recommended doses appears to be safe for most people. Some sources suggest that prolonged use might cause side effects.
- The most common side effects are headaches and sleep and gastrointestinal problems.
- Asian ginseng can cause allergic reactions.
- There have been reports of breast tenderness, menstrual irregularities, and high blood pressure associated with Asian ginseng products, but these products’ components were not analysed, so effects may have been due to another herb or drug in the product.
