The duration of taking Chinese medicine is related to the disease to be treated, the composition of the medicine and the side effects, and cannot be generalized. Different diseases are treated by different drugs and require different methods of administration. In terms of drug composition and efficacy, for example, deworming drugs are usually taken in the morning on an empty stomach; tonic drugs are recommended to be taken on an empty stomach to facilitate maximum absorption of drug components; tranquilizers are usually recommended to be taken before bedtime to facilitate a peaceful sleep; stomachic drugs are usually recommended to be taken after meals to facilitate elimination of accumulation; and in critical cases, they can be taken at any time, regardless of the time. In addition, some drugs have side effects such as gastrointestinal irritation, so it is recommended to take them after meals to avoid nausea, vomiting, diarrhea and other discomforts. There are certain contraindications during the consumption of Chinese medicine, such as abstaining from spicy stimulation and alcohol. It is recommended to consult a doctor or herbalist before taking the medication, and take the medication according to the medical advice according to different diseases and different drug ingredients.
