Drinking 500 milliliters of Chinese medicine at one time is a bit too much. Generally, adults are advised to take 200 to 300 milliliters at one time, but if the concentration of the medicine is too low, more can be taken in moderation. If you are decocting the medicine yourself at home, it is recommended to boil out 400 to 600 milliliters of a pair of medicines and take them in two doses, about 200 to 300 milliliters at a time. If it is a good herbal soup dispensed by a doctor, it is recommended to store it under the doctor’s instruction and take it as required. Occasional overdose of Chinese herbal medicines does not affect patients much, but patients who regularly consume excessive amounts of Chinese herbal medicines may have difficulty in drinking and stomach bloating. In addition, overdose of herbal medicines that stimulate the stomach and intestines may cause abdominal pain and diarrhea, etc. The specific dosage is recommended to be taken under the guidance of a physician.
