The term “complete grain does not transform” is a Chinese medical term, which mainly means that the water and rice eaten are still the same as the water and rice excreted in the bowels, and are not digested, which is mostly thought to be a problem with the function of the spleen. According to TCM, the function of the spleen is to transport and transform the food eaten into water and grain and spread the essence throughout the body. If the food eaten and the food expelled are the same, it proves that the spleen is weak to the extreme and should be treated promptly. Otherwise, a malfunction of the spleen, which is the essence of the latter, means that the body is unable to absorb food and will gradually weaken and develop very serious diseases. Failure to complete the grain is relatively common in clinical practice and is mainly seen in children and the elderly as well as in people who are very weak and can be corrected by tonifying the spleen and strengthening the stomach. Common foods and medicines are mainly found in hawthorn and medicines such as Gui Shen Wan and Jian Spleen Wan.
