Generally, Chinese herbal medicines are more plant-based and belong to the herbal category, which can regulate the balance of the body’s surface and interior, yin and yang, cold and heat, deficiency and reality. Pay attention to a calm diet, as food that is not calm will cancel out the medicinal properties and lead to treatment failure. Therefore, when taking Chinese medicine, doctors will tell patients to have a light diet after prescribing the medicine, and the Chinese medicine boxes are printed with avoidance of spicy and greasy foods, which have an effect on the medicinal properties of Chinese medicine. Excessively oily food is not eaten as much as possible, because herbal medicine absorbs these oily things, which will lead to the spleen and stomach being too thick and not absorbing the medicine, and even too oily will lead to excretion, and the herbal medicine will be excreted before it is absorbed.
