If you take a single dose of Chinese medicine four times as prescribed by the doctor, the effect is usually not affected. If you change the way you take the medicine on your own, it will affect the effectiveness of the medicine. Generally, in cases where the dose of Chinese medicine is large or accompanied by vomiting symptoms, it may be necessary to divide the Chinese medicine into four doses. If a patient takes one dose of Chinese medicine four times under the guidance of a physician, the efficacy of Chinese medicine is usually not affected and there is no need to worry too much. However, unauthorized changes in the dosage and time of administration, such as splitting a pair of Chinese medicines into four doses, will usually affect the efficacy of Chinese medicines to a certain extent. In order to ensure the efficacy of Chinese medicine, patients should also pay attention to their diet during the medication period, avoiding cold, spicy and stimulating foods, such as ice cream and chili peppers. Patients should also pay attention to avoid smoking and drinking alcohol. At the same time, patients should also properly store the Chinese herbs to avoid moisture or mold, which may affect the efficacy of the herbs. Patients are advised to take Chinese medicines according to the doctor’s instructions and not to use or change the dosage without authorization.
