Chinese medicines should be soaked and then decocted, and the boiling method should be adjusted according to different medicinal properties and efficacy as prescribed by the doctor in order to get the best medicinal effect. For example, it is not advisable to decoct for a long time for antidepressants and heat-clearing medicines, and it is necessary to decoct for a long time for ores and poisonous medicines. First of all, the medicine will be washed, soaked in cold water for 30 minutes to 1 hour or so; after that, on the fire decoction, large fire boil and then turn to small fire, about half an hour after the soup will be poured out, and then add cold water to continue to decoction, about half an hour after the soup will be poured out again. Mix the two decoctions and divide them into two or three parts. It should be noted that for some dense or toxic drugs, in order to better decoct the active ingredients or remove the toxicity, they should be decocted for half an hour before adding other drugs; for drugs containing volatile ingredients, in order to prevent the loss of efficacy, they need to be added after 20 minutes of decoction of the other drugs, so as to minimize the volatility of the drugs. The specific decoction method, decoction time, number of times and drinking time of the drugs should be adjusted appropriately according to different medicinal properties and efficacy, and it is recommended to take them according to the doctor’s advice.
