If you've been watching the Olympics over the past week, you may have
noticed some of the competing athletes are sporting more than medals.
Spectators are noticing the red, circular marks on the skin of athletes.
This is a result of a technique called cupping. Cupping is a traditional Chinese medicine (TCM) practice that involves
placing cups on the skin to create suction. This practice dates back
over 2,000 years but has received recent attention in the media due to
its use by world-class athletes for injury relief. The cups used in
cupping are typically made of bamboo, glass, or earthenware.
