Stomach yin deficiency (insufficient yin fluid in the stomach) suggests choosing foods that nourish yin and clear away heat (nourish yin essence and clear away heat), such as yucca, mulberry, yam, etc. The specific effect is affected by whether the symptoms are right, the severity of the disease and other factors, and there is no such thing as the best food. Due to insufficient depletion of yin fluid in the stomach, it is easy to cause yin deficiency and fire exuberance (deficiency of yin essence in the body and hyperactivity of deficiency fire), which results in hidden pain in the stomach, dry mouth, emaciation, dry stools, and lack of hunger and desire for food. Daily diet should be based on clear tonic products, and it is recommended to consume more fresh vegetables and fruits, such as tomatoes, pears, mulberries and so on. It is not recommended to consume warm and dry products such as green onions, peppercorns, chili peppers, etc., so as not to aggravate the depletion of yin fluid. In addition to dietary modifications, you should go to the hospital in time and follow the doctor’s instructions to avoid aggravation of the condition.
