The shelf life of boiled Chinese medicine in the refrigerator has a lot to do with the way the Chinese medicine is stored and the composition of the Chinese medicine. If the boiled herbal medicine is packed in an airtight plastic bag, placed in the refrigerator and refrigerated at 0℃-5℃, the shelf life is about 30 days, and it is recommended to try to take it within 14 days to avoid affecting the efficacy of the medicine. If boiled Chinese medicine is held in a container provided by the patient himself, it is generally recommended to take it on the same day, if the decoction is not seen in the air it can be kept for 3 days, if the Chinese medicine contains more starch, protein, sugar and other substances in its composition, it may be more prone to deterioration. If the herbal medicine belongs to the category of purging heat and detoxifying, the preservation time is relatively longer; if the herbal medicine belongs to the category of tonic, the preservation time is usually relatively shorter. At present, Chinese herbs are usually boiled by hospitals or pharmacies on behalf of the herbs. It is recommended that before taking the herbs home and refrigerating them, avoiding direct sunlight, the preservation time of the herbs may be longer.
