Some modern cupping practitioners have shifted to using rubber pumps to create suction versus more traditional heat methods.
When the hot cup is placed on your skin, the air inside the cup cools and creates a vacuum that draws the skin and muscle upward into the cup. Your skin may turn red as the blood vessels respond to the change in pressure.
With dry cupping, the cup is set in place for a set time, usually between 5 and 10 minutes. With wet cupping, cups are usually only in place for a few minutes before the practitioner removes the cup and makes a small incision to draw blood.
After the cups are removed, the practitioner may cover the previously cupped areas with ointment and bandages. This helps prevent infection. Any mild bruising or other marks usually go away within 10 days of the session.
Cupping is sometimes performed along with acupuncture treatments. For best results, you may also want to fast or eat only light meals for two to three hours before your cupping session.
What conditions can cupping treat?
Cupping has been used to treat a wide variety of conditions. It may be particularly effective at easing conditions that create muscle aches and pains.
Since the cups can also be applied to major acupressure points, the practice is possibly effective at treating digestive issues, skin issues, and other conditions commonly treated with acupressure.
A 2012 review of studiesTrusted Source suggests cupping therapy’s healing power may be more than just a placebo effect. The researchers found that cupping therapy may help with the following conditions, among others:
shingles
facial paralysis
cough and dyspnea
acne
lumbar disc herniation
cervical spondylosis
However, the authors acknowledge that most of the 135 studies they reviewed contain a high level of bias. More studies are needed to assess the true effectiveness of cupping.
