Hair products generally refer to foods that are irritating and can lead to aggravation of diseases, prolonged healing time or induce disease recurrence after eating. Malantou is a perennial herb, which has the functions of clearing away heat and toxic materials, diuresis and digestion, so it does not belong to hair. Malantou is rich in vitamin C, β-carotene, nicotinic acid, dietary fiber and other nutrients. Proper consumption can provide nutritional supplements for the human body and help to avoid constipation symptoms caused by insufficient dietary fiber intake. However, Malan is cool and contains more cellulose, which will cause irritation to the spleen and stomach after eating. It is not recommended that people with spleen and stomach deficiency and cold and pregnant people eat too much, which will lead to abdominal pain and diarrhea. Hair products are generally irritating, such as mutton, beef and seafood. However, influenced by personal physique, hair products are not exactly the same. Under normal circumstances, people who are sick or recovering from a serious illness and are in poor health are not recommended to eat hair products, which is not conducive to the recovery of the disease and may also lead to prolonged course of disease. It is suggested that a light diet under the guidance of a doctor can effectively shorten the course of disease.
