In a narrow sense, taboo refers to the dietary taboos when taking medicine for a disease. The taboo is a feature of Chinese medicine, which has been attached great importance by medical practitioners, and its content is also widely found in the “Nei Jing”, “Typhoid”, “Jin Kui” and other medical texts. The broad sense of taboo includes the diet of all sick people, regardless of whether they take medicine or not, and can also include the dietary attention of some special physical people, such as physiologically thin or fat, hot or cold body normal people. These people, although not patients, also need to have some dietary precautions. Allergic skin diseases avoid: onion, garlic, ginger, chili, pepper, chicken, sheep, fish, shrimp, crab, etc., that is, the so-called fishy hair. Hot disease avoid mouth: tobacco, alcohol, spicy, dry, fried, onion, garlic, ginger, chili, pepper, lamb, dog meat and other hot food. General allergic diseases are mostly hot diseases, so the two avoid eating similar. Cold disease avoidance: cold food, such as watermelon, pear, crab, turtle. Food compatibility contraindications: licorice, Huanglian, orris, umeboshi avoid pork; mint avoid turtle meat; poria avoid vinegar; turtle fish avoid amaranth; chicken avoid eel; honey avoid raw onion; asparagus avoid carp; thornbush avoid fish, crab, puffer fish, donkey meat; white atractylodes avoid garlic, peach, plum, etc., but sometimes these compatible foods are sometimes not completely scientific and credible. Seasonal taboos: spring less acid food should eat spicy sweet, summer less hot and humid food, autumn and winter avoid eating cold. Obese body avoidance: fat, sweet and thick, all containing high fat, high sugar, high calorie food; “fat people more phlegm damp”, wood fungus, silver fungus, mushrooms, etc. should be less food. Thin small body avoid: “thin people more fire”, so some warm food should not eat more.
