The statement of “which three kinds of people should not take American ginseng” is not accurate enough. Those who are allergic to American ginseng should not take it, and those who have hyperactivity of liver yang and those who have fever and cold need to use it with caution. As ginseng has the effect of tonifying the vital energy (replenishing the root of the body’s vital energy), ginseng can be taken by those who have deficiency of yang qi and patients with cold deficiency, but those who have hyperactivity of liver yang and those who have fever with cold need to be cautious, and those who are allergic to ginseng are prohibited from taking ginseng in order to avoid triggering an allergic reaction. When taking American ginseng, it is not suitable to consume it together with Wu Ling Ling Ling and Anti Veratrum, so as to avoid drug interactions or other adverse reactions. Modern medicine believes that American ginseng contains a variety of amino acids, pectin, niacin and other nutrients, per 100 grams of dried Artemisia ginseng slices containing 309 calories, 55 grams of carbohydrates, 12.6 grams of protein, 0.5 grams of fat, 15.7 grams of cellulose. It can provide nutrition for the body and maintain the normal physiological function of the body. It is recommended to take Koryo under the guidance of a doctor to avoid adverse effects.
