Cupping is a practice used in traditional medicine in several parts of the world. It involves creating suction on the skin using a glass, ceramic, bamboo, or plastic cup.
There has been some research on cupping, but most of it is of low quality. Cupping may help reduce pain, but the evidence for this isn’t very strong. There isn’t enough high-quality research to allow conclusions to be reached about whether cupping is helpful for other conditions.
Cupping leaves temporary marks on the skin. Sometimes, it can cause side effects such as persistent skin discoloration, and it may worsen eczema or psoriasis. If cupping equipment is used on more than one person, it should be sterilized between patients to avoid spreading diseases.
