The evidence for the use of American ginseng to reduce high blood pressure is still conflicting.
Two randomized controlled trials found that supplementation with a specific American ginseng extract reduced systolic blood pressure, but not diastolic blood pressure, in individuals with type 2 diabetes compared to a control.[1][2] However, another study including people with hypertension but without diabetes, which used 6 different American ginseng preparations over an 8-day period, failed to find a significant effect on blood pressure.[3] More research is required to reach a definitive conclusion, as factors such as the duration of treatment, the type of American ginseng extract used, and the baseline medical condition of the participants may influence the outcomes.
