Hair is food or substance that can trigger or induce diseases or lead to the recurrence or even aggravation of the original diseases. Hair will make the body's balance of Yin and Yang imbalance, mostly some highly nutritious or irritating items. The word "fawu" was first recorded in Puji Fang in the Ming Dynasty, and since then, 74 food names have appeared in the documents that do not eat "fawu", and * * * involves 15 categories of food. Some scholars have summarized the common "hair products" according to the characteristics of four qi and five flavors and diseases, and found that sweet and pungent "hair products" account for a large proportion, especially pungent and warm "hair products", most of which have the function of dispelling cold and tonifying, and are easy to fire and help damp, so people with yin deficiency, yang excess and body dampness need to avoid eating. Other kinds of "hair" can be summarized as moving wind, accumulating cold, moving blood, moving qi, etc. These hair can induce or even aggravate wind syndrome, cold syndrome or latent diseases.
However, the "hair" should vary from person to person, and the "taboo" should also be based on its own actual situation. Whether a food is a "hair" for a person or a disease should be determined according to the patient's physique, the nature of the disease, the course of the disease, the severity of the disease and other factors. It is recommended to consult a doctor according to your own condition to determine whether there are related taboos.
