The interval of cupping depends on the degree of can suction and extraction and the time of staying cupping, at present, there is no strict clinical regulation, usually once a day or every other day, the specific treatment interval needs to be decided by the clinician according to the condition. Cupping can be due to the different degree of can suction and extraction, so that after the opening of the local color of cupping there are different degrees of severity. Generally, cupping can be left for 5-15 minutes, and different degrees of suction force can be chosen according to different conditions, which will result in localized flushing or ecchymosis. If the patient is cupped with higher suction force, the ecchymosis will be heavier. Patients who do not think they can tolerate cupping once a day can choose to do it every other day. The more specialized type of cupping requires bloodletting, so it is usually performed every few days, or once a day if the condition is more severe. If patients want to seek cupping treatment, it is recommended to go to a regular medical institution to ensure the safety of the treatment process.
