Precautions for using American ginseng 1. Don't drink tea: because tea contains a lot of tannic acid, which will destroy the active ingredients in American ginseng, you must take American ginseng 2 to 3 days before drinking tea.　　2. Do not eat radish.　　3. Be alert to adverse reactions: some people will have chills, drop in body temperature, loss of appetite, abdominal pain and diarrhea after taking American ginseng; some will have dysmenorrhea and delayed menstruation; some will have allergic reactions, with upper and lower limbs presenting scattered blisters of varying sizes, itching abnormally, and blisters can be self-absorbed and subside after the medication is stopped.　　Not everyone can serve American ginseng: American ginseng in the treatment of fitness has unique features, but the abuse is also harmful to prevent two kinds of abuse tendency: the first is blindly used for a variety of patients. Clinical studies have shown that the use of American ginseng and its preparations in patients with chronic hepatitis B is not only detrimental to the recovery of the disease, but also aggravates and prolongs it. Another example is that many malignant tumor patients use American ginseng and its preparation after operation or radiotherapy, and some of them even use it for a long period of time in order to recover as soon as possible, but it is often contrary to their wishes, and it has been proved by practice that only when the patients have obvious symptoms of deficiency of lung and stomach yin after operation or radiotherapy can they use it symptomatically to play the actual effect of American ginseng. It can be seen that American ginseng is not suitable for any patient.　　The second one is to take American ginseng as food. As American ginseng has certain anti-fatigue, anti-hypoxia or brain-boosting effects, many people carry American ginseng or its preparations in their daily life to prepare for anti-fatigue. Unbeknownst to them, American ginseng is also a kind of medicine, which can not be taken whenever you want. According to relevant information, about 70% of busy modern people are in sub-healthy state, and the main feature of sub-health is fatigue, so the use of American ginseng to fight fatigue is not symptomatic? Actually not, because fatigue is the performance of relative imbalance of human body's qi, blood, yin and yang, which needs to be comprehensively adjusted through spiritual regulation, balanced nutrition, work and rest time and other aspects, and is not a problem that can be solved by taking American ginseng. Moreover, there are many cases where it is not suitable to use American ginseng to fight fatigue, because American ginseng is only a kind of Chinese medicine that nourishes yin and replenishes qi, not a panacea.
