Cupping is an increasingly popular therapy in the field of alternative medicine. It can complement traditional and alternative medical treatments and also is used for relieving stress and relaxing the body.

Cupping Therapy, also known as Myofascial Decompression, can be traced back to ancient Egyptian, Chinese, and Middle Eastern cultures. It’s been described as one of the oldest treatment interventions, and its history dates back to 1500 B.C.In ancient Chinese medicine, people used it for lung conditions, fever and other ailments. Today, practitioners use it for pain relief and musculoskeletal injuries like strains, sprains and back injuries.

Cupping is the application of a vacuum (negative pressure) through a hollow vessel (cup) to the body. This negative pressure pulls the tissue into the cup to gain a response from the tissues themselves (skin, connective tissue, muscles, ligaments and joints), the circulatory system, nervous system and fascia system to create a positive therapeutic outcome.

Cupping helps with pain, inflammation, blood flow, relaxation and well-being, and is often referred to as a reverse type of deep-tissue massage.

Doesn't sound too scary does it??

The mechanical effect of cupping increases local blood flow and stretches the underlying tissue.  According to a 2018 review, the effects of cupping therapy include: promoting the skin’s blood flow, changing the skin’s biomechanical properties, increasing pain thresholds, improving local anaerobic (without oxygen) metabolism, reducing inflammation, and boosting cellular immunity.

Some of the benefits of Cupping include:

• Relieving muscle tension
• Improving Range of Motion (ROM) when there is a decrease from injury or condition
• Improving blood flow & oxygenation to local tissue sites
• Can help clear inflammation by cupping above & below the site of inflammation (never directly over it!)
  Improving mobility & function in scar tissue
• Supporting mobility in fascia restrictions and connective tissue generally
• Calming to superficial pain patterns
  Relieving the issues causing the pain (muscle tension)

It's worth reframing this question honestly: the research base for cupping is dominated by small, low-quality trials, so "conditions cupping treats" is a stronger claim than the evidence supports for most of what follows. A better framing is what's been studied, and how confident the research actually lets us be.

Where the evidence is most consistent (though still generally low-to-moderate quality): chronic pain conditions, specifically low back pain, neck pain, and knee osteoarthritis, along with pain from herpes zoster (shingles) and migraine. Multiple systematic reviews converge on cupping showing a measurable, short-term pain-reduction effect for these, even though individual trials are often small and inconsistently designed.

Where cupping has shown a signal, but usually as part of combined treatment rather than on its own: facial paralysis, cervical spondylosis, and acne. The research behind these mostly evaluated cupping paired with acupuncture or other treatments, not cupping alone, so it's difficult to credit cupping specifically as the active ingredient.

Where the claim needs a significant caveat most cupping content leaves out: hypertension, diabetes mellitus, and rheumatoid arthritis appear on a lot of "conditions cupping treats" lists, including our own previous version of this page. Here's the problem: most of the research behind those specific claims used wet cupping, the bloodletting variant where small incisions are made before suction is applied, not the dry cupping we sell equipment for and that falls within scope of practice for massage therapists. Results for wet cupping and hypertension specifically are mixed even within their own research base; one controlled study found a short-term reduction in blood pressure that didn't hold at longer follow-up, and a formal review of the evidence concluded there wasn't enough to establish effectiveness. Carrying these claims over to describe dry cupping, which is what most people reading this page will actually be doing or receiving, isn't accurate.

The most useful summary comes from a 2011 overview that pooled every systematic review of cupping evidence available at the time and has held up reasonably well since: relatively clear evidence exists for only one use, pain relief, and even there the authors noted real doubts remain given how weak the underlying trials tend to be. Evidence for every other condition cupping gets used for, hypertension and rheumatoid arthritis included, was judged insufficient to draw a conclusion either way.

None of this means cupping does nothing outside of pain. It means the confident, wide-ranging condition lists you'll see across a lot of cupping marketing content overstate what the current evidence actually supports. Pain relief is the place cupping's evidence is strongest; everything else should be understood as an area of ongoing, inconclusive research rather than an established use.

A cupping treatment should generally be comfortable, and a slight tugging sensation when the cups are first applied is normal. If suction feels sharply painful rather than like tugging or pulling, it's likely too strong and should be eased off.

That said, it's worth being straightforward about the marks themselves: whether they're tender afterward genuinely varies. Some people find them painless; others, including experienced practitioners describing their own marks, report tenderness that lasts a day or two. Suction strength, duration, and individual sensitivity all play a role, so telling every client to expect zero tenderness sets up a confusing experience for the person whose marks do ache a little.

Cupping marks are a form of ecchymosis, the general medical term for skin discoloration caused by blood outside the vessels. The marks typically fade within one to two weeks.

Some people report feeling lightheaded, dizzy, or mildly flu-like after a session. If you experience these, mention it to your practitioner.

There's a lot of noise around what cupping marks mean, so here's what's actually established versus what's still just theory.

What causes them: The suction ruptures small surface capillaries, and blood moves into the surrounding tissue, visible as a colored mark. This is a different mechanism from an impact bruise, which comes from blunt-force compression. A 2025 forensic pathology study examined this directly: when researchers looked beneath cupping marks during a postmortem exam, they found no hemorrhage in the deeper fat or muscle tissue, the kind of damage blunt trauma leaves behind. The marks were confined to the surface capillary layer.

Is it a bruise? Not in the blunt-trauma sense (a contusion), since there's no impact involved. But by the actual medical definition, ecchymosis simply means blood outside the vessels causing visible discoloration, and a cupping mark fits that definition. So: not a contusion, but a form of ecchymosis, which is the more precise way to describe it than either "definitely a bruise" or "definitely not a bruise."

What determines how dark a mark gets: Suction strength, how long the cup stayed in place, and individual factors like skin fragility, age, and medications that affect clotting. Generally speaking, a particularly dark or pronounced mark usually just means the cup was left in one spot longer than needed or the suction was stronger than necessary, not that anything unusual happened in the body.

Does mark color mean anything diagnostically? Traditional Chinese Medicine treats mark color as one part of a larger diagnostic picture, not a standalone reading. Outside of that framework, no controlled research has established that mark color reliably indicates anything specific about a person's internal state. That doesn't make the traditional framework meaningless to practitioners who work within it, but it's not something we can present as settled science.

The goal of cupping is to support circulation and provide the therapeutic effect the technique is being used for, not to produce the darkest possible mark. A dramatic mark is not evidence of a more effective treatment.

Even though it is considered safe, Cupping isn’t for everyone. It is not recommended for people with liver, kidney or heart failure or those with a pacemaker. As well, it can’t be used if you have hemophilia, anemia or similar blood disorders, heart disease or are on blood thinners. 

If pregnant, avoiding cupping on the upper and lower abdomen applies at every stage. Views genuinely differ beyond that: some clinical guidance treats pregnancy generally as a reason to avoid cupping altogether, while other guidance, mostly from practitioners with specific prenatal training, describes modified, light-suction treatment later in pregnancy with the abdomen still off-limits. The first trimester calls for the most caution across the board.

If you don't have specific training in prenatal bodywork, the safer default is not to perform cupping on pregnant clients rather than improvising a modified approach. If you do have that training, anemia and blood thinner use still rule it out regardless of trimester.

If there is suspicion of an infection or an open wound, Cupping should not be performed. 

For a full outline on the Contraindications to Cupping. 

Directly, no. A cupping mark is blood that has moved from inside a capillary to just beneath the skin. Nothing is extracted from the body through the skin's surface; the escaped blood is reabsorbed the same way any bruise resolves.

Where cupping plausibly does something relevant is more indirect: it increases local blood flow, which can support the body's own circulatory and lymphatic systems in clearing normal metabolic waste, the ordinary cellular byproducts your body processes on its own regardless of cupping. That's a real, if modest, mechanism. It's a different claim from "cupping pulls toxins out through the skin," which isn't physiologically accurate for dry cupping.

So: does cupping remove toxins directly? No. Can it support the circulatory and lymphatic systems that handle waste as part of their normal function? Plausibly, yes, though this is a supporting role rather than a distinct detox mechanism.

The instructions to not shower after a Cupping treatment stem from the practice of Wet Cupping - where an incision is made on the skin and a cup is placed over that to draw blood out of the body and into the cup. This is generally only practiced in Traditional Chinese Medicine (TCM) and Middle Eastern styles of Cupping such as Hijama.

Dry Cupping leaves the skin intact and is the only type of cupping that is within the scope of practice for Massage Therapists.

So, can you shower after Cupping? If you have had Dry Cupping, absolutely you can. If you have had Wet Cupping, adequate time should be given for the wounds to heal where blood may have been drawn from the skin.

After a Cupping Therapy treatment it’s important to take some precautions to help minimize the risk of side effects and ensure you get the most benefit from the treatment. Some preventive measures to consider after cupping include:

• Avoid exposing the treated area to extreme temperatures. After Cupping, it’s best to avoid exposing the treated area to extreme temperatures, such as hot showers, saunas, or ice baths. This can help minimize the risk of further irritation or injury to the skin.
• Avoid overexerting yourself. It’s important to avoid any strenuous exercise or activity for at least 24 hours after Cupping. This can help prevent further injury or damage to the treated area and give your body time to heal.
• Abstain from alcohol. It’s best to avoid drinking alcohol for at least 24 hours after Cupping. This can help prevent further inflammation or irritation in the body.

If you experience any unusual or concerning symptoms, such as severe pain, swelling, or infection after Cupping, inform your physician.
