The practice of cupping, which has roots in Chinese, Egyptian, and Middle Eastern cultures, was originally used as a traditional healing method. However, it has gained popularity in the fitness community as a recovery aid. Cupping therapy involves the application of cups to the skin using either heat or suction to promote peripheral blood flow, alleviate pain, detoxify the body, treat migraines and acne, lower cholesterol, and boost immunity.
There are two primary forms of cupping: dry and wet. The initial step for both dry and wet cupping is the same. The practitioner ignites a flammable material such as alcohol inside the cup and places it on the skin, causing a vacuum to form as the fire goes out. The cup is left in place for three to five minutes to increase blood flow to the surface of the skin. In wet cupping, the therapist proceeds by removing the cup and making superficial incisions or punctures on the affected area of the skin. The therapist then applies a second round of suction to remove a small amount of blood.
Doctors who practice conventional "Western-style" medicine generally assert that there is no conclusive scientific evidence supporting the effectiveness of cupping, and no clear explanation for its purported advantages. Meanwhile, practitioners of traditional "Eastern-style" medicine emphasize the more than 2,000 years of practical experience with cupping, as well as its holistic approach to promoting overall health and wellness.
Cupping's benefits may be attributable to a range of mechanisms, some or all of which may have a global effect, although additional research is needed to provide definitive proof. The Immune Modulation theory suggests that altering the skin's microenvironment modulates biological signals to activate the neuroendocrine immune system. According to the Genetic theory, mechanical and oxidative stress on the skin activate and inhibit gene expression. The Pain-Gate theory proposes that inducing pain in one area may alleviate pain in other areas. Cupping may release Nitric Oxide, according to the Nitric Oxide theory, promoting vasodilation and blood flow mediation. Wet cupping therapy's superficial scarifications could activate a cascading wound-healing effect. Finally, the placebo theory contends that the benefits of cupping may be attributed to the expectation of beneficial effects, which can result in measurable results.
Various clinical studies have investigated the effects of cupping, but conducting a scientifically rigorous study can be difficult. The primary challenge lies in conducting a double-blind, placebo-controlled trial in which neither the participant nor the researcher knows whether the treatment administered is the actual therapy or a placebo.
A review of 135 randomized clinical trials found that the majority of studies on cupping lacked scientific rigor. The majority of these studies focused on treating acne and skin breakouts, and 85% of the studies were deemed to have a high risk of bias. Additionally, many studies combined multiple treatments rather than solely focusing on cupping. In contrast, a separate analysis of 75 randomized control trials investigating the use of cupping to alleviate neck pain found that cupping did offer meaningful benefits in reducing short-term pain, similar to the effects of acupuncture. Furthermore, a small but well-designed study revealed that wet cupping therapy was able to remove oxidants and decrease oxidative stress, and had similar benefits to donating blood. At present, the scientific literature does not provide conclusive evidence regarding the mechanisms and efficacy of cupping as a standalone treatment.
Although cupping therapy is generally considered safe, rare side effects can occur. These may include skin discoloration that can last for several days, as well as uncomfortable pinching sensations caused by the suction. Wet cupping may result in scar formation. Other potential adverse effects include headaches, dizziness, muscle tension, nausea, skin infections, or pain at the cupping site.
Cupping remains a controversial topic, but it is a relatively inexpensive, noninvasive, and generally low-risk therapy that can be a valuable addition to your health-promoting routine. Combining cupping with other therapies such as acupuncture, acupressure, and massage can enhance its potential benefits. However, if you are uncertain about the scientific efficacy of cupping, it may be prudent to wait until further research has determined a more definitive answer before undergoing the therapy yourself.
