Just drink plum and soak in water. Plums are good for people. First, they are widely used in medicine. Huang Yao has the habit of applying dried plums to her navel when she has a headache. In addition, the green plum juice is cooked and put into the bottle. Once you have a stomachache, dip it with chopsticks to relieve the pain. Some people also soaked the plum in white wine and sealed it for a month, which became a mellow and delicious plum wine. Drinking a little plum wine at ordinary times can treat rheumatism, muscle pain, sprain and contusion, and lumbar muscle strain. Li Shizhen wrote in Compendium of Materia Medica: "Plum is the fruit of blood separation, which can strengthen the stomach and astringe the lungs, warm the spleen to stop bleeding and eliminate phlegm, reduce swelling and detoxify, promote fluid production and quench thirst, and treat chronic cough and diarrhea."
