How long can I take Chinese medicine on an empty stomach? Generally, Chinese medicine is taken 2 times a day with an interval of about 12 hours before and after breakfast and dinner. If you want to be in a more urgent and serious condition, you can also take it 3 times a day. If you are seriously ill or have restricted food intake such as ascites, you can also concentrate the soup or take it several times a day, depending on the patient’s condition. If the soup is for the treatment of stomach diseases, it is recommended to take it on an empty stomach, so that it can act directly on the lesion to reduce the impact of food requirements absorption. If it is a soup medicine that breaks the Qi, activates the blood, softens the hardness, and is more stimulating to the gastrointestinal tract, it is recommended to be taken after meals, with an interval of 30-45 minutes between eating.
