What Do People Use Cupping For? Common Reasons and What the Research Says

What Is Cupping?

Cupping is a traditional practice in which cups are placed on the skin and the air inside is reduced to create suction. It has been used in traditional Chinese medicine for thousands of years, and similar practices appear in other cultures. Modern cups are usually made of glass, silicone or plastic, and suction can be created by heat, a hand pump or a squeezable cup. Practitioners generally describe a few styles: dry cupping, where cups stay in place on intact skin, moving cupping, where cups are glided over oiled skin, and wet cupping, which involves small skin incisions and is performed by trained practitioners. Because the practice varies so much between practitioners and traditions, research findings on cupping are not always directly comparable, which matters when reading the evidence below.

Why Do People Use Cupping?

People turn to cupping for several reasons, and the motivation often depends on the setting. Within traditional Chinese medicine, practitioners use it based on ideas about balancing the flow of qi and relieving stagnation, which is a cultural and philosophical framework rather than a measured scientific mechanism. In everyday use, people commonly describe it as a way to ease muscle tension and soreness, particularly around the neck, shoulders and back, and some athletes include it in recovery routines. Researchers have also studied it for specific conditions, mainly pain-related ones such as neck pain, low back pain and knee osteoarthritis, and, in smaller bodies of research, acne and facial paralysis. Whether a person finds it relaxing or helpful is personal, and that is separate from the question of what controlled studies can confirm.

What Does the Research Say?

The honest summary is that the evidence is limited and mostly low in quality. An overview of eight systematic reviews, led by researchers at Beijing University of Chinese Medicine, found that the reviews themselves were well conducted but the trials inside them were generally poor, and it concluded that cupping may be beneficial for pain-related conditions, acne and facial paralysis without allowing firm conclusions. A 2023 evidence-mapping study of cupping for pain outcomes found no high-quality evidence of efficacy, with most findings rated very low to moderate quality. For neck pain, low back pain and knee osteoarthritis, some moderate-quality evidence suggested pain scores may improve. A separate review of musculoskeletal and sports rehabilitation rated the evidence for improved soft tissue flexibility as moderate, and for reduced low back or neck pain as low to moderate.

Why Is the Evidence Hard to Pin Down?

Several features of cupping make it difficult to study well. Techniques vary widely, with dry, wet and moving cupping, different cup types, pressures and treatment times all appearing in the research, so the results of one study do not always apply to another. In a review of musculoskeletal studies, most trials compared cupping with no treatment, which cannot separate a real effect from the effect of receiving attention and expecting to feel better. Giving a convincing placebo is also hard, because suction is obvious to the person receiving it. Many trials are small, which is why reviewers keep calling for larger, better designed studies. None of this means cupping does nothing. It means the current evidence is not strong enough to say so with confidence.

How to Think About Cupping

A balanced way to approach cupping is to separate three questions: whether it is a meaningful cultural and traditional practice, whether some people find it pleasant or relaxing, and whether controlled research has confirmed specific health benefits. The first two are matters of tradition and personal experience, and for many people the answer is yes. The third is where the evidence is still limited. If you are thinking about cupping for a particular health concern, it is sensible to speak with a doctor or qualified practitioner first, and to be cautious of any source that promises specific results. Reliable information describes what has been studied, how strong the evidence is and what remains uncertain, rather than presenting cupping as a cure or a proven treatment for any condition.
