It is not better to boil herbal medicines for as long as possible. The duration of decoction needs to depend on the specific type of medicine in order to bring out the best medicinal effect. Please consult a medical professional for specific decoctions and methods of administration. The heat and time of decoction need to be determined according to the performance of the medicine. Generally, antiemetic and diaphoretic medicines need to be decocted with high heat (wu huo) for a shorter period of time; tonic medicines need to be decocted with low heat (wen huo) for a longer period of time. Some medicines have different decoction methods such as first decoction, second decoction, package decoction, another decoction, melting, soaking, rinsing, and decoction of soup instead of water due to different textures. Generally, gold and stone, minerals, shells and other medicines need to be decocted first, and need to be broken and decocted for 20~30 minutes before other medicines are decocted with them. Medicines with aromatic odor need to be put down later, after other medicines have been boiled for 5~10 minutes. Powdered or fluffy medicines need to be wrapped for decoction, and need to be wrapped with gauze for decoction. Valuable herbs need to be decocted separately and need to be decocted separately in another pot for 2~3 hours. Gelatinous or soluble drugs need to be melted, which can be added directly into the decoction and heated to melt. Some medicines which are easily soluble in water or whose efficacy will be destroyed by decoction need to be soaked, and can be soaked directly in boiling water. For light and valuable medicines, they can be powdered into fine powder and taken with warm water or liquid. Some drugs that are easy to make the soup turbid need to be decocted instead of water, and the supernatant should be decocted first to replace the water before decocting other drugs. It is recommended to consult a professional Chinese medicine practitioner for the specific decoction method of Chinese medicine to avoid the incorrect method affecting the efficacy of the medicine.
