In dietotherapy, ginger can be said to be blindly Chinese medicine. Whether eaten raw or heated to maturity, its spicy taste will not disappear. The ingredient of this spicy substance is curcumin. Curcumin is beneficial to gallbladder in human body. Ginger ketone has the effects of invigorating stomach, appetizing and stopping vomiting. Ginger oil can promote systemic blood circulation and cause sweating. Ginger soup can promote gastric acid secretion and intestinal peristalsis. It can be seen that ginger is quite effective in Chinese medicine. As a vegetable, it can be used for seasoning, but it is not allowed to use shredded ginger and Jiang Mo as cold dishes, and it is not recommended to slice, dice or shred ginger as pickles. In other words, the medicinal value of ginger is far greater than the edible value as a vegetable raw material. As the saying goes, "medicine is toxic in three parts", and a large amount of raw food is toxic to human body. Li Shizhen pointed out in Compendium of Materia Medica: "If you eat ginger for a long time, you will get hot and you will have to taste it again. Anyone who suffers from hemorrhoids will eat and drink more, and it will become very fast. People with carbuncle eat too much, and then the meat goes bad. " This is a sincere warning to people who love ginger. We don't advocate eating ginger in our diet. If you have this hobby, please correct your habits quickly.
