Cupping is an ancient and very effective therapy in which glass cups are heated to create a vacuum within the cup which is then placed on the skin. They may remain static or be slid along muscles to achieve therapeutic results.

The purpose of cupping is multifaceted however generally the treatment is to help facilitate blood flow, help remove metabolic waste, and restore normal circulation of intracellular fluids to muscles and fascia. Often there is a change of color of the skin after cupping which is a good prognostic sign because it shows that static blood has been drawn from congested tissue into the more superficial capillary beds where it may be properly re-circulated.
