In the course of clinical treatment, TCM dermatologists often advise patients what not to eat, which are “hairy substances”. So, what is the meaning of “hair products” in Chinese medicine? What belongs to the Chinese medicine “hairy things” A, the definition of hairy things ancestral medicine recognized early on that certain foods may induce skin diseases, such as the Ming Dynasty “Surgical Authentic” said: ” chicken, goose, mutton, clams, puffer fish, shrimp, crab …. For example, in the Ming Dynasty’s “The Art of Surgery”, it was said that “chicken, goose, mutton, mussels, clams, puffer fish, shrimps, crabs, and fishy seafood can move the wind and cause itching. When it comes to “hairy substances”, traditional Chinese medicine believes that it includes both broad and narrow meanings. The broad sense of hair refers to the normal intake of healthy people, or sickness and medicine and post-illness conditioning of the diet process, due to improper diet and induce a disease, stimulate new diseases, hinder treatment, aggravate the disease or affect the body recovery of a class of food. Narrow sense of hair refers to the food that can cause similar to modern medicine refers to allergic diseases. From the clinical analysis of dermatology refers to the narrow category of hair products. Second, the common hairy food and classification according to folk customs and “with the rest of the diet” and other literature, the clinical common hairy food, such as certain meat such as chicken, donkey meat, beef, mutton, dog meat, goose meat, pheasant meat, etc.; carp, silver carp, squat fish, crabs, yellow fish, squid fish, pomfret, shad, perch, sturgeon, grass carp, octopus, flounder, minnow, striped bass, bighead carp, eel, mussels, clams, shrimp, crab and other aquatic products. shrimp, crab and other aquatic and seafood; toon, brassica, coriander, mustard, spinach, bean sprouts, lettuce, eggplant, wild rice, leeks, bamboo shoots, pumpkin, ciguatera, mushrooms and other vegetables; apricots, plums, peaches, ginkgoes, mangoes, prunes, cherries, lychees, melons and other fruits; onions, peppers, ginger, garlic and other spicy and stimulating seasoning food; in addition, there are buttermilk, white wine, wine brew In addition, there are fermented foods such as cheese, white wine, liquor; and peas, yellow soybeans, tofu, tofu milk and other legumes. However, the food sources can be classified as ① edible mushrooms: mainly mushrooms, shiitake mushrooms, etc. ②Seafoods: mainly scallops, yellowtail, pomfret, mussels, shrimps, crabs and other aquatic products. ③Vegetables: mainly bamboo shoots, mustard, pumpkin, spinach, etc. ④Fruits: mainly peaches, mangoes, etc. ⑤ Poultry and livestock: mainly rooster, beef, lamb, etc. From the point of view of dermatology, the above foods can make the skin lesions aggravated. Third, the dermatological identification of disease avoid eating hair food dermatological evidence of common diseases, such as eczema, acne, urticaria, etc.. Many patients do not understand what food can be eaten after the disease, which food can not be eaten, think that after the skin disease all the “hair” are to avoid eating. There is a consensus that hair products can aggravate skin diseases, and from the literature of Chinese medicine, some foods can aggravate the disease, and some foods counteract the medicinal effects of Chinese medicine. However, in clinical practice, it is necessary to identify the disease and avoid food. From the perspective of Chinese medicine, there are many diseases caused by fire, heat and poison, such as hot sores (herpes simplex), snake sores, and dermatitis, etc. In clinical practice, patients are asked to avoid foods that promote fire and heat, such as beef, mutton, chicken and wine. Some diseases are caused by heat, dampness, and phlegm, such as acne, and patients should be asked to eat less spicy, sweet, oily, and other damp and heat-generating products; most allergic diseases are caused by wind, but wind is the longest of all diseases, and clinically, such allergic diseases are most common in outpatient clinics. The main sea fishy products are scallops, yellow fish, pomfret, mussels, shrimp, crab and other aquatic products, most of these foods are salty cold and fishy, for the body allergy, easy to induce allergic disease attacks. Vegetables with volatile odor are mainly bamboo shoots, mustard, spinach, cilantro, etc., because the smell of aromatic has the function of table dispersion. In addition, there are fermented types, brined products, a certain this meat, such as wine, brined meat, kimchi, etc.. Although there are many hair products, I personally feel that there are individual differences in the avoidance of hair products, such as cilantro the same disease in different patients may be able to eat, some can not eat. Especially patients suffering from chronic skin diseases in the treatment process should be self-made summary. Neither affect the absorption of nutrients, but also to prevent the aggravation of the disease.
