The decoction of Chinese medicine should be made in a ceramic pot, soaked for 15-30 minutes, and then decocted according to the order of decoction. The decoction time for different drugs varies between 10-25 minutes, but the general decoction time is 20-30 minutes, and each dose of Chinese medicine needs to be decocted twice, and the combined liquid of the two doses should be taken separately according to the doctor’s prescription. The efficacy of some Chinese medicines is closely related to the method of decoction, such as some drugs need to be decocted first, such as mineral drugs, animal horns and nails, toxic and strong drugs, because the toxic components are not heat resistant, the long heating time can reduce the toxicity of the drug or make the toxicity of the drug disappear. The decoction time is different for herbs with different medicinal effects, such as short decoction time for antiphlogistic drugs, which usually can be kept for 10-15 minutes after boiling, while for tonic herbs, a longer decoction time is needed so that more active ingredients of the drug can be decocted into the liquid to ensure better clinical efficacy. Therefore, if patients choose Chinese herbal medicine, they need to decoct the herbal medicine strictly according to the doctor’s prescription, otherwise it may affect the efficacy of the medicine.
