Pineapple does not have the same efficacy and effect as drugs, can only provide the body with water, carbohydrates and other nutrients, if the body is not feeling well, it is recommended that patients follow the doctor’s instructions to standardize the treatment. Pineapple is a fruit, not a drug, so it can not play a role equivalent to the efficacy of drugs, and does not have the role of the treatment of disease, but pineapple can be consumed to replenish the body’s nutrients, such as water, sugar, potassium, vitamin C and so on. Pineapple contains bromelain and glycosides, which may irritate the oral mucosa if consumed directly, and may also cause allergic reactions such as itching and redness of the skin, so it is recommended that pineapple be soaked in salt water before consumption. If the body is unwell, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor for standardized treatment, not blindly use prescriptions, in order to avoid the delay of the condition.
