Cupping therapy dates back to ancient Egyptian, Chinese, and Middle Eastern cultures. One of the oldest medical textbooks in the world, the Ebers Papyrus, describes how the ancient Egyptians were using cupping therapy in 1,550 B.C.
In general, Western medical societies are skeptical of the health claims made by cupping therapy supporters. "Available scientific evidence does not support cupping as a cure for cancer or any other disease," states the American Cancer Society. "Reports of successful treatment with cupping are mainly anecdotal rather than from research studies."
But a 2012 study published in the journal PLoS ONE suggests that cupping therapy may have more than a placebo effect. Australian and Chinese researchers reviewed 135 studies on cupping therapy published between 1992 and 2010. They concluded that cupping therapy may be effective when combined with other treatments like acupuncture or medications in treating various diseases and conditions, such as:
But the researchers acknowledge that many of the studies in their review may have contained some bias. They say better studies are needed to draw a definite conclusion.
Types of Cupping Therapy
There are various types of cupping therapy, including:
Dry cupping (suction only)
Wet cupping (combination of suction and controlled medicinal bleeding)
During both types of cupping, a flammable substance such as alcohol, herbs, or paper is placed in a cup and set on fire. As the fire goes out, the cup is placed upside down on the patient's skin.
As the air inside the cup cools, it creates a vacuum. This causes the skin to rise and redden as blood vessels expand. The cup is generally left in place for five to 10 minutes.
A more modern version of cupping uses a rubber pump to create the vacuum inside the cup. Sometimes practitioners use medical-grade silicone cups. These are pliable enough to be moved from place to place on the skin and produce a massage-like effect.
