The length of medication is not clearly defined in TCM, and the specific duration of medication is usually based on the actual situation, commonly in 3 days, 7 days, 15 days, or 1 month. Generally, at the beginning of the disease, the doctor will diagnose the patient by looking, smelling, asking, and cutting, and then determine the amount and duration of medication according to the disease and physical condition, and then decide to reduce, add, adjust, or stop the medication according to the patient’s response to the medication after the initial medication. In addition, the doctor may also consider the patient’s medical insurance reimbursement, if the local medical insurance departments related to outpatient prescription course restrictions, the prescription of too many drugs will not be reimbursed, then the doctor may only prescribe the prescribed course of drugs, and then prescribe the remaining amount of drugs in batches. If a patient has doubts about the amount of medication prescribed, or feels that the amount prescribed does not improve his or her symptoms, he or she can ask his or her treating physician for more or less medication, if necessary, according to his or her actual situation.
