Herbal medicines are boiled once on the first day and it is usually not recommended to continue the decoction on the next day. Herbal medicine is usually taken as one dose per day, decocted with water and divided between morning and evening. Generally Chinese herbs are to be decocted 2 times. The juice from the two decoctions is usually mixed, divided into 2 portions and consumed within one day. If the decoction is divided into 2 days, because after the first decoction, many of the active ingredients of the Chinese medicine have been decocted. Therefore, if water is added to the second decoction, the active ingredients in the second decoction will be less than those in the first. If the decoction is drunk as it is, then the overall efficacy of the medicine will be discounted. Therefore, it is generally necessary to mix the two medicinal liquids and then evenly divided into two parts, one in the morning and one in the evening. This will ensure that the efficacy of the two medicines is the same.
