As a traditional Chinese medicine, American ginseng should not be taken by people with weak middle yang and cold dampness in the stomach, but there is no saying that three kinds of American ginseng should not be eaten. American ginseng is the dried root of Panax ginseng, which is a plant of the family Wujiaceae. It has the effect of tonifying qi and nourishing yin, clearing heat and generating fluids, and is effective in improving or treating qi deficiency and yin deficiency, deficiency and heat, coughing, phlegm and blood, internal heat and thirst (internal fever accompanied by symptoms such as eating, drinking, urinating, etc.), and dryness of mouth and pharynx. Since American ginseng is cold and cold in nature, it can hurt yang and help dampness, so it is not suitable for people with weakened middle yang (spleen yang weakness is more serious) and cold dampness in the stomach. It is worth reminding that American ginseng is incompatible with quinoa, so American ginseng should not be used with quinoa. In addition, do not blindly use Chinese herbs on your own, you should do so under the guidance of your doctor’s diagnosis, in order to prevent adverse effects.
