Wet cupping is a treatment method where blood is drawn using tiny incisions with cupping, and it is especially effective for relieving pains. According to Chinese medicine, ‘where there is proper flow, there is no pain; where there is no proper flow, there will be pain’, as such, pain happens where there is blockage in the meridian system and where chi and blood stagnates. Wet cupping is effective to remove bruises, restore blood flow and revitalizes the meridian system, and it has been used clinically to treat a variety of pains. Modern medicine also supports that wet cupping therapy is capable of stimulating local nerves, regulating corresponding blood vessels and muscular functions, remove spasms in blood vessels and smooth muscle tissues, thus resulting in noticeable pain relief.
