“Cupping” is a form of alternative therapy that actually originated in China. It involves the placement of glass cups upon the skin to create suction, which is said to facilitate healing with the body’s flow of blood. This process allows for the extraction of unwanted and harmful toxins absorbed into the human body.
Even today, this cupping technique is widely used as a means of alternative medical therapy.
It is also known as Gua sha, Hijama and [simply] a form of acupuncture.
