Is this Chinese medicine decocted first and then taken?

There is no medicine that decocts first and then decocts. Before decocting the medicine, remember to soak the medicine in cold water for half an hour, and then decoct the medicine in the soaked water, so that it is easier to decoct the effective components of the medicine. Decoct the decoction with strong fire for 20 minutes, and then with low fire 15 minutes. A pair of medicine should be decocted twice, once in the morning and once in the afternoon, and the amount of water should be too much and too little.
