Generally, 9 a.m. and 3 p.m. are the prime time for the body to absorb drugs, so this is the best time to take Chinese medicine. However, the time of taking herbal medicines differs for different medicinal properties. Generally speaking, for the treatment of deficiency and gastrointestinal diseases, they should be taken 30-60 minutes before meals. For the treatment of heart and lung diseases and other general diseases, it is usually better to take them 30 minutes after meals to avoid stimulation of the stomach and intestines and to reduce side effects. Chinese medicines that help digestion or stimulate the stomach and intestines should also be taken after meals. The tonic medicines and laxative medicines should be taken on an empty stomach before meals, where laxative medicines such as rhubarb and fire marijuana should be taken in the early morning or during the day, avoiding taking them before bedtime or at night. Deworming medicine should also be taken in the morning on an empty stomach.
