    Panax quinquefolius, commonly referred to as “American ginseng”, appears to be useful in preventing some viral upper respiratory tract infections. It may also have hypoglycemic properties (may reduce blood glucose) and improve cognition. However, more research is needed.

    Overview

    Dosage information

    American ginseng is typically used in dosages of 200–400 mg once or twice daily.[1][2]

    Some condition-specific studies, such as studies assessing the effect of American ginseng on diabetes, blood pressure, or workout capacity, have used larger dosages (2–3 grams daily) of standardized extracts for up to 12 weeks.[3]
