The black and purple skin after fire cupping usually takes 3~14 days to eliminate, and it is impossible to generalize due to the existence of variability in personal constitution.
Fire cupping is the use of heat generated when the fire burns, the air inside the canister is emptied to form a certain negative pressure, the canister is adsorbed on the skin. As this process will lead to localized congestion and capillary dilation, some patients will experience redness, black and purple skin. Usually, if the patient’s skin black purple range is small, usually more than 3 ~ 7 days can be eliminated on their own.
However, due to individual variability, some patients have a larger area of dark purple skin, the recovery time is relatively longer, it may take 8 to 14 days, and it is impossible to generalize. It is important to make a comprehensive judgment based on your own situation.
If patients experience discomfort after fire cupping, they should report to their doctor in a timely manner.
