If stored properly without deterioration, boiled Chinese medicine can be drunk overnight, which has no effect on the efficacy of the Chinese medicine, especially in summer when the weather is hot and the indoor and outdoor temperatures are high, so if it is not stored properly, it can easily deteriorate, and if it is cloudy and has a bad smell, it cannot be taken orally. Usually, a pair of Chinese medicine can be boiled at once and stored in a refrigerator, and can be heated slightly when taken orally. If you use a decoction machine, many pairs can be boiled at once and stored in a refrigerated cabinet for many days without deterioration. Therefore, if the decoction is stored properly, it can be taken orally even for many days without affecting the efficacy of the medicine.
