The shelf life of Chinese medicine decoction depends on the packaging, ambient temperature and the composition of the medicine, and cannot be generalized. If the herbal medicine is packed in an airtight vacuum bag, it can have a shelf life of one week at room temperature, but the shelf life is usually no more than 2-3 days when the room temperature is higher than 25℃; if it is refrigerated at 0-5℃, the shelf life is about 30 days, and it is recommended to take it within 7 days as much as possible. However, if the Chinese medicine is not held in an airtight vacuum container, it is generally recommended to take it on the same day; if you want to continue taking it on the next day, it is recommended to put it in the refrigerator’s freezer and it should not be kept for more than 3 days. If the ingredients of herbal medicines contain more starch, protein, sugar, etc., which are more prone to deterioration, they should be taken as soon as possible. In addition, the Chinese herbal medicine decoction should also be kept in a cool and ventilated place to avoid deterioration of the medicine and affect the therapeutic effect, and patients should take it as soon as possible according to the course of treatment. After all of them are taken, you can go to the relevant departments of the hospital for follow-up to see the therapeutic effect.
