Hair growth is a concept of traditional Chinese medicine. Hair has a broad sense and a narrow sense. In a broad sense, hair is food, and its nature and taste are the same as those of some diseases. After eating, it may aggravate the imbalance between yin and yang, and then aggravate or induce some diseases, including fever, wind, damp heat, chills, blood deficiency and so on. In a narrow sense, hair products are foods that can poison and help fire, and may induce old diseases and add new diseases. In real life, people generally refer to hair in a narrow sense.

Chinese medicine believes that eggs are hair in a broad sense, and they are also hair-blowing. They are warm and have a good nourishing effect. But for people with urticaria, eczema, stroke and other diseases, eggs have the properties of rising hair, dispersing qi and clearing heat, which can make evil spirits escape, thus aggravating the above diseases.

Modern medicine believes that eggs may induce or aggravate some allergic diseases, because allergens in eggs combine with human serum IgE to cause allergic reactions. At present, it is found that five protein components in egg white can combine with human serum IgE to cause allergic reaction. They are ovomucin, ovalbumin, ovotransferrin, lysozyme and ovomucin. Therefore, people who are allergic to eggs should avoid eating eggs, and people with allergic diseases should eat eggs carefully. Eggs belong to hair, bread does not belong to hair. Under normal circumstances, food is also food, and moderate consumption will not cause side effects or discomfort to most people, but will only induce diseases related to certain special constitutions. Hair refers to foods that are nutritious or irritating, and are particularly prone to induce certain diseases or aggravate existing diseases. Hair taboo is of great significance in diet and dietotherapy. If you have chronic diseases, don't eat more eggs.
