Decoction of Chinese medicine refers to a way of cooking the captured Chinese medicine in a casserole, which can be made by adding cool drinking water, soaking it for 20-30 minutes, then adding water to submerge the medicine, and placing the casserole on the stove over medium heat to cook it. The utensils for decocting Chinese medicine are usually made of casserole, because the material of casserole is stable and will not react chemically with the ingredients of the medicine, so that the heat transfer is even and gentle, but you can’t use iron pots and copper pots and so on, because iron pots and copper pots and so on are unstable chemically and easy to oxidize. It is recommended that patients should preferably decoct Chinese medicines under the guidance of a doctor, and the dosage should follow the doctor’s instructions.
