The number and frequency of fire cupping is mainly related to the purpose of cupping and the patient’s physical condition, and cannot be generalized. The principle of cupping is to use the jar as a tool to consume the air inside the jar by burning the fire, so that the jar becomes negative pressure, in order to achieve the effect of opening the meridians, dispelling wind and cold, reducing swelling and pain. If the patient is currently in pain, catching a cold, or has a high level of evil energy, cupping can be done every other day for 3 consecutive days for better results. For daily health care, daily cupping is not recommended, but once every 3 days to once a week is usually recommended, because the purpose of health care is to smooth the flow of qi and blood, and too many cupping sessions may damage the positive qi and deplete the yang qi. In addition, patients should pay attention to keeping warm after cupping and should not take cold showers to avoid sharp contraction of the open pores, which may lead to cold.
