Cupping therapy is one of the oldest and most widely practised methods of traditional Chinese medicine, used for more than two thousand years alongside acupuncture, herbal medicine and tuina. Rounded cups are applied to the skin to create a gentle suction that draws up the underlying tissue. This lifting and decompression invigorates the circulation of qi and blood, releases tight muscles and fascia, and helps the body to clear stagnation and expel pathogenic factors. Although cupping has recently become familiar in the West through its use by athletes, it has deep roots in Chinese, Middle Eastern and European folk medicine.
A brief history
Records of cupping in China go back to the Han dynasty, where animal horns were used to create suction – the early Chinese term for the practice translates as ‘horn method’. Over the centuries the materials evolved from horn to bamboo, ceramic and, eventually, glass. Cupping is described in classical texts such as Ge Hong’s Handbook of Prescriptions for Emergencies and was refined throughout the Tang and Qing dynasties. Today it remains a core technique in Chinese medicine clinics worldwide.
How cupping works in Chinese medicine
From the perspective of Chinese medicine, free movement is health and stagnation is the root of much pain and disease. Cupping moves qi and blood through the channels and the muscle layer, dispels cold and damp that have lodged in the tissues, and draws stagnation and pathogenic factors to the surface where they can disperse. The suction brings fresh, nourishing blood to the area and frees congestion – which is why cupping is so effective for pain, stiffness and tension. In the language of the channels, it ‘opens’ the surface and the collaterals, restoring flow where it had become blocked.
From a biomedical viewpoint, the negative pressure is thought to increase local blood flow, lift and mobilise the fascia and connective tissue, stimulate the nervous system and lymphatic drainage, and trigger a mild inflammatory healing response in the treated area.
The main methods of cupping
- Retained (stationary) cupping – cups are placed over an area or specific acupuncture points and left in position for five to fifteen minutes. This is the most common method and is excellent for localised pain and tension.
- Sliding (moving) cupping – oil is first applied to the skin and the cup is then glided smoothly over a larger area such as the back or thigh. It feels like a deep, decompressing massage and is ideal for broad areas of muscular tightness.
- Flash cupping – a cup is rapidly applied and removed many times in quick succession over an area, providing gentle, rhythmic stimulation without leaving strong marks; useful for weaker patients and for ‘tonifying’ the area.
- Wet (bleeding) cupping – a few tiny, superficial pricks are made on the skin with a sterile lancet before the cup is applied, drawing out a small amount of blood. This stronger method is reserved for stubborn stagnation, certain heat conditions and acute sprains, and must only be performed by a properly trained practitioner under strict hygiene.
- Needle cupping – a cup is placed over an inserted acupuncture needle, combining the actions of both therapies on a single point.
The cups and how suction is created
Cups may be made of glass, bamboo, earthenware or modern silicone. Suction is created in one of two ways. In fire cupping, a flame is briefly introduced into a glass cup to consume the oxygen, and the cup is then placed quickly on the skin, where the cooling air creates a vacuum (the flame never touches the body). In pump cupping, a hand-operated valve draws the air out of a plastic or silicone cup, allowing precise, adjustable suction. Silicone cups can also be squeezed and applied for gentle sliding work.
What cupping is used for
Cupping is best known for musculoskeletal pain and tension: neck, shoulder and back pain, sciatica, stiffness, fibromyalgia-type aches, and sports injuries. By releasing tight muscles and fascia and improving local circulation, it can bring rapid relief and improved range of movement. It is also traditionally used to support the treatment of:
- Respiratory complaints – coughs, colds, and the early stages of chest congestion, with cups placed over the upper back to help the Lung disperse and descend.
- Digestive and general complaints – some practitioners use gentle abdominal or back cupping to support digestion and general wellbeing.
- Stress and fatigue – many people find a cupping session deeply relaxing, easing the physical tension that accompanies stress.
Cupping is very often combined with acupuncture within the same treatment, the two therapies complementing one another.
What to expect in a session
Your practitioner will first assess your condition and decide which areas to treat and which method to use. The skin may be lightly oiled. As the cups are applied you will feel a firm tightening and a pulling sensation as the tissue is drawn up; most people find this comfortable and even pleasant, and many feel a notable release of tension. Cups are usually left in place for several minutes, or moved over the area. A typical session lasts twenty to forty minutes. Afterwards it is wise to keep the area warm, drink water, and avoid strenuous exercise, alcohol and cold exposure for the rest of the day.
The marks – and what they mean
The most talked-about feature of cupping is the round marks it can leave. These are not bruises in the ordinary sense and are generally painless: they are caused by the suction drawing stagnant blood and fluid from the deeper tissues toward the surface. Practitioners read their colour as a sign of the degree and nature of the underlying stagnation – from light pink (little stagnation) through red and purple to dark purple (marked, long-standing stasis). The marks typically fade within three days to a week as the body reabsorbs them. Areas with little stagnation often show almost no marking at all.
Safety, cautions and who should take care
In trained hands cupping is very safe. Nevertheless it is adapted or avoided over broken, inflamed, irritated or sunburnt skin, over varicose veins, large blood vessels and bony prominences, and on the abdomen and lower back during pregnancy. It is used with extra care – or avoided – in people with bleeding disorders or who take anticoagulant (blood-thinning) medication, in those with very fragile skin or severe oedema, and in the frail or elderly. Wet cupping in particular demands proper training, sterile single-use equipment and safe disposal. As with any therapy, always consult a qualified, registered practitioner who can assess whether cupping is suitable for you.
Frequently asked questions
Does cupping hurt? Most people find it comfortable; you feel a strong pulling or tightness rather than pain.
How long do the marks last? Usually a few days up to about a week.
How often should I have it? This depends on your condition; acute problems may be treated more frequently, chronic ones at wider intervals – your practitioner will advise.
