For example, when taking traditional Chinese medicine for clearing internal heat, hot foods such as onion, garlic, pepper, mutton and dog meat should not be eaten; When taking warm traditional Chinese medicine to treat "cold syndrome", we should fast cold food. There are also a lot of records in ancient literature: licorice, coptis, platycodon grandiflorum and ebony avoid pork; Mint avoids turtle meat; Poria cocos is jealous of vinegar; Turtle fish avoid amaranth; Chicken avoid eel; Honey turns into onions; Asparagus avoids carp; Schizonepeta avoids fish, crabs, puffer fish and donkey meat; Atractylodes macrocephala avoids garlic, peaches and plums. This shows that when taking certain drugs, you should not eat certain foods. If you eat taboo food, the curative effect will be unsatisfactory or counterproductive. In addition, due to the disease, all foods that are not easy to digest or have special irritation, such as cold, greasy and fishy, should be avoided during taking the medicine. For example, when you have a cold or a rash in children, you should not eat cold, sour and greasy food; When treating chest distress and abdominal distension caused by qi stagnation, beans and sweet potatoes should not be eaten because these foods are easy to cause flatulence. Others, such as edema patients eat less salt; Patients with asthma and allergic dermatitis should eat less "hair food" such as chicken, sheep, pig's head, fish, shrimp and crab.
"Taboo" can't be absolute, and it varies from person to person and due to illness. For general patients, especially chronic patients, if they are "taboo" for a long time and there are many kinds of fasting, they can't maintain the normal intake of nutrients needed by the human body, but reduce the resistance of the human body, which is not good for restoring health. Therefore, under the guidance of doctors, they can eat foods that increase nutrition appropriately to avoid nutritional deficiency.
