Hypertension is generally not allowed to take ginseng, whether fresh or dried. Modern pharmacological studies on anesthetized animals have shown that small doses can raise blood pressure and large doses can lower blood pressure, but the animals soon develop tolerance, so the effect of ginseng on lowering blood pressure in animal experiments is not satisfactory. The mechanism of hypertension is complex, and the treatment is not only to dilate the blood vessels, such as secondary hypertension, but also to treat the primary disease. In short, hypertension should be treated in a standardized manner, rather than listening to some folk remedies.
