In some of the above studies, it is possible that ginseng was used in insufficient amounts or for an inadequate length of time; a more effective regimen for enhancing endurance performance may be 2 grams of powdered root per day or 200 to 400 mg per day of an extract standardized for 4% ginsenosides, taken for eight to twelve weeks.6 Short-term intense exercise has also not been helped by Asian ginseng according to double-blind trials,7, 8 but one controlled study reported increased pectoral and quadriceps muscle strength in non-exercising men and women after taking 1 gram per day of Asian ginseng for six weeks.9
Used in the recommended amounts, ginseng is generally safe. In rare instances, it may cause over-stimulation and possibly insomnia.10 People with uncontrolled high blood pressure should use ginseng cautiously. Long-term use of ginseng may cause menstrual abnormalities and breast tenderness in some women. Ginseng is not recommended for pregnant or breast-feeding women.
Consuming caffeine with ginseng increases the risk of over-stimulation and gastrointestinal upset.
