Chinese herbal medicine can be served in a thermos cup after boiling, but it should not be left for too long. Chinese medicine needs to be taken in time after boiling, it is generally not recommended to leave it for too long. If you can’t drink it in time and need to save it, you can put it in the freezer, wait for the temperature to drop to a certain level, and then save it through the thermos cup, which can make the medicine maintain a relatively low temperature, but generally don’t exceed 24 hours. Although thermos cups can preserve medicinal liquids, they are not preferred. The recommended method of preserving Chinese medicines is to boil them, pour them into a ceramic bowl, let them cool and store them in the refrigerator freezer, and then take them out and heat them up when you take them. Do not store Chinese medicine by this method for more than 48 hours at the longest, otherwise it may lead to deterioration and affect the efficacy.
