Persimmons are sweet, tasty and nutritious, and it is generally recommended to eat 1-2 pieces per day. They are rich in sucrose, glucose, fructose, protein, carotene, amino acids, vitamins and trace elements such as zinc and manganese, and have many effects such as moistening the lungs and resolving phlegm, clearing heat and producing fluid, astringent intestines and stopping dysentery, strengthening the spleen and stomach, producing fluid and moistening the intestines, and cooling the blood to stop bleeding. However, it should be eaten in moderation and not in excess. Persimmons are cold in nature, so people with cold bodies should eat them sparingly and avoid eating them with crab and other cool foods. Persimmons contain a large amount of tannic acid, pectin and gum and are recommended to be eaten after meals. If eaten on an empty stomach, they may react with stomach acid and form clots, known as “persimmon stones”, which are not easily crushed and can easily cause gastric mucosal congestion, erosion, edema, ulcers and, in severe cases, gastric perforation. Persimmons need to be ripe before eating, but when they are not ripe, they can easily cause allergies, which may lead to rashes, itchy skin and other symptoms, and even anaphylactic shock in severe cases.
