The dosage of liquid medicine needs to vary from person to person. If it is an adult, leave about 300ml of medicine in half a bowl. For children or people who are tired of drinking Chinese medicine, put about 200ml of medicine in a small bowl. The administration method of Chinese medicine decoction is: before breakfast and after dinner, 1, twice a day.
