How many milliliters of Chinese medicine to drink in general is mainly determined by the patient’s condition and physical tolerance. Normally, about 200ml of Chinese medicine should be drunk at one time, but for patients who need to restrict water intake such as heart failure, the dose can be reduced under the guidance of the doctor. One dose of Chinese medicine is usually decocted with 400ml and taken twice in the morning and evening, 200ml each time, but for some patients who restrict water intake, such as those with heart failure or renal insufficiency, they can choose to decoct 100ml~200ml in concentrated form, 50ml~100ml each time they take it, so patients can consult with a professional doctor and take Chinese medicine under the guidance of the doctor. Diet during the period of taking Chinese medicine should try to avoid greasy, spicy stimulation, cold food, so as not to aggravate the burden on the stomach and intestines, and it is best to keep a good mood and proper rest during the period of taking medicine.
