Decocting apparatus: casserole, stainless steel, glass, enamel, etc. are preferred. When decocting medicine, avoid using iron, aluminum and copper pots. Because the physical and chemical properties of the former are relatively stable, it is not easy to react with the ingredients in the drug to ensure the curative effect of the drug. However, the iron and copper components are relatively active and easily react with the components in the medicine, which affects the curative effect.
Soaking method: before decocting, put the medicine into the medicine pot, add clean cold water to soak the medicine, add water to submerge the medicine surface for 3-5cm, and soak for 20-60 minutes (if the time is too long, the medicine will go moldy and deteriorate), which is beneficial to decocting the effective components of the medicine.
Decocting method: each dose is boiled twice. For the first time, the soaked medicinal herbs are boiled with strong fire, and then boiled with medium and small fire to keep the herbs boiling; The second decoction requires less water (based on the submerged surface), and the heat is the same as that of the first decoction. You'd better cover it when you blow it up. Under normal circumstances, it is not advisable to open the lid frequently when cooking, otherwise the smell will be lost and the efficacy will be reduced.
Decocting time: the calculated time after the medicine is boiled.

Filtration of liquid medicine: the amount of decoction liquid medicine should be determined according to the patient's condition, age and other specific conditions. The amount of adults is about 200-300ml, and that of children is about 1/4- 1/2, that is, 50- 150ml.
Administration time: one dose per day, once in the morning and once in the evening. Take the first decoction in the morning and the second decoction in the afternoon, so that the concentration and function of the two decoctions in the body can be uniform and reliable. You can also mix the two decoctions and take them twice in the morning and afternoon with an interval of about 6 hours. It is better to take the medicine decocted on the same day than to keep it. Tonics should be taken half an hour before meals; Heat-clearing drugs and drugs that stimulate gastrointestinal tract should be taken half an hour after meals; Please follow the doctor's advice for other drugs.
How to take it: There are three ways to take it: hot, warm and cold. Generally speaking, antiperspirants and warming tonics should be taken warm. Cold-dispelling drugs and drugs for treating joint pain and ulcer should be taken hot, while heat-clearing and detoxifying drugs should be taken cold.
Precautions: Chinese medicines wrapped in paper or gauze are often seen in Chinese medicine bags, which are marked with the words "fry first, then fry, and take orally". Be sure to follow the requirements, otherwise it will affect the effect of the medicine. In the process of decocting, water can be added according to the situation, but it should be constantly stirred to prevent overflow and paste.
