The following doses have been studied in scientific research:
BY MOUTH:
- For a lung disease that makes it harder to breathe (chronic obstructive pulmonary disease or COPD): 100 mg to 6 grams of Panax ginseng three times daily for up to 3 months has been used.
- For memory and thinking skills (cognitive function): 200 to 400 mg of a specific Panax ginseng extract (G115, Pharmaton SA) taken once daily or in two divided doses for up to 12 weeks, or 200 to 960 mg as a single dose, has been used.
- For erectile dysfunction (ED): 1400 to 2700 mg of Panax ginseng, taken in two or three divided doses per day for up to 12 weeks, has been used.
- For flu (influenza): 200 mg of Panax ginseng extract (G115) daily, starting 4 weeks before getting a flu shot and continuing for 8 weeks after, has been used. Also, 1 gram of Panax ginseng extract three times daily for 12 weeks has also been used.
- For fatigue in people with multiple sclerosis (MS): 250 mg of Panax ginseng twice daily for 3 months has been used.
- For increasing response to sexual stimuli in healthy people: 3 grams of Korean red ginseng, a form of Panax ginseng, daily for 8 weeks has been used. A specific combination product (ArginMax for Women, The Daily Wellness Company), taken daily for 4 weeks, has also been used.
APPLIED TO THE SKIN:
- For early orgasm in men (premature ejaculation): A cream (SS-Cream) containing Panax ginseng and other ingredients has been applied to the glans penis one hour before intercourse and washed off before intercourse. *
Panax Ginseng tends to be taken in doses of 200 to 400 mg daily for general 'preventative' medicine, although some studies on the inclusion of Panax Ginseng in a multivitamin suggest doses as low as 40mg might be bioactive. The 400 mg dose appears to confer most cognitive benefit.
These doses refer to standard 'Ginseng Extract' which is around 2-3% total Ginsenosides, and is a once daily dosage.
Trials using Korean Red Ginseng extract for erectile health and libido enhancement tend to use 3 grams of total KRG extract daily, in three doses of 1000 mg. *
Korean ginseng is usually made into a powdered form from the dry root and taken by mouth as a supplement. Although there is a tincture (a liquid preparation made with alcohol) and tea form available, most of the clinical research studies are performed using ginseng in the powdered/supplement form.
Ginseng should be stored at room temperature and kept dry, away from heat.
Always take Korean ginseng (and any other herbal supplement) as directed by the healthcare provider. The average dose of Korean ginseng is about 200 to 400 mg per day as an overall health promotion/preventative herbal supplement. The 400 mg dose may provide the highest cognitive benefit from Korean ginseng.
Other medical experts recommend 200 mg per day and suggest taking a two-week break from taking ginseng every two to three weeks. This is to avoid the possibility of getting a toxic reaction from the build-up of ginseng in the body. “Most published research studies have used a standardized Panax ginseng extract in a dosage of 200 mg per day,” says American Family Physicians.
Do not take Korean ginseng at bedtime since the side effect of insomnia has been reported. Also, do not take Korean ginseng for long time spans (no more than three months). Be sure to discuss the specific safety precautions of taking Korean ginseng with your healthcare provider. *
