There have been some large, well-conducted trials and a variety of smaller laboratory research studies looking into the actual benefits of Asian ginseng. However, the evidence does not strongly support the claimed benefits for the plant.
Currently there are studies looking into Asian ginseng’s potential role in treating insulin resistance, cancer, and Alzheimer's disease.
Short-term use of ginseng at recommended doses appears to be safe for most people. However, some sources suggest that prolonged use might cause side effects. You should consult with your health care provider before using this product.
The most commonly reported side effects are headaches, gastrointestinal problems (such as stomach upset), and sleep difficulties. Ginseng can also cause allergic reactions.
There have been reports of ginseng-containing products causing breast tenderness, menstrual irregularities, and high blood pressure. However, as these products' ingredients were not analyzed, the side effects may be due to another herb or drug in the product.
Asian ginseng has the potential to decrease blood sugar, which can occur more frequently if you have diabetes. Therefore, people with diabetes should use extra caution with Asian ginseng, especially if they are already taking blood-glucose-lowering drugs, or other natural health products such as bitter melon and fenugreek, that may also cause low sugar levels.
Before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking.
