Cupping therapy is not recommended for menstruating women. If cupping therapy is not used properly for menstruating women, there may be hazards such as increased menstrual flow or prolonged menstrual period. Cupping is a method of external treatment in which a can is used as a tool, and combustion, suction, steam and other methods are used to create negative pressure inside the can, so that the can is adsorbed to acupuncture points or certain parts of the body surface to produce benign stimulation, to adjust the body’s functions and prevent diseases. Cupping has the effect of activating blood circulation, relieving pain, reducing swelling and dispersing knots. Since cupping has the effect of activating blood circulation, cupping during menstruation may cause discomfort such as increased menstrual flow and prolonged menstrual period. If you need to use cupping therapy, it is recommended to go to a professional medical institution.
