The decoction process is particularly important for Chinese medicine to maximize its therapeutic effect. In order to bring out the therapeutic effect of drugs, traditional healers in the past generations have summed up a set of decoction methods in their long-term practice. In a prescription, some drugs have to be decocted first (e.g. tortoise board, substitution ochre), some have to be decocted later (e.g. rhubarb, sandy sage), and some need to be decocted separately (e.g. ginseng). Self-decoction allows the decoction time to be adjusted according to the actual needs of the prescription. Self-decoction can be adjusted according to the actual needs of the prescription, while decoction by proxy is mainly done by automatic decoction machine in a closed, high-pressure environment. In this case, the decoction cannot be made according to the requirements of the prescription and the decoction time cannot be adjusted according to the requirements of the prescription, which may affect the efficacy of the medicine. The decoction process can be controlled by yourself, so you can take the decoction as you go, ensuring that the soup is fresh and safe to drink.
