Cupping Therapy

About this therapy

Cupping therapy is a traditional Chinese medicine technique where glass, bamboo or plastic cups are placed on the skin to create suction or negative pressure. This is believed to improve blood flow, relieve muscle tension, promote healing, dispel cold and dampness, and balance qi. Cups may be stationary, moved across the skin, or combined with acupuncture or bleeding. It commonly leaves temporary circular red or purple marks (cupping bruises) that fade in 3-10 days. Widely used as a safe complementary therapy for pain and other conditions when performed by trained practitioners in clinical settings. It is promoted in China's grassroots TCM services and recognized in WHO traditional medicine training references.

How it works

In TCM theory, the suction draws out pathogenic factors (such as wind, cold, dampness), stimulates blood and qi circulation, relaxes fascia and muscles, reduces stagnation and inflammation. Modern views suggest it increases local blood flow, may affect connective tissue, and triggers anti-inflammatory responses. Techniques include retained cupping, flash cupping, moving (sliding) cupping, medicinal or wet cupping (with minimal bleeding).

What to expect

A typical session lasts 10-30 minutes. Patients lie comfortably while cups are applied (often on back, shoulders or painful areas) creating a pulling/tight sensation that is usually tolerable. Skin under cups reddens or bruises mildly. Marks peak in 1-3 days and resolve in 7-10 days. A course typically involves 6-12 sessions, 1-3 times per week, tailored to condition. Generally relaxing; mild soreness or warmth may follow.

Typical programme

20 min per session, about 8 sessions per course

Cautions

• Avoid on broken, infected, ulcerated or highly sensitive skin
• Contraindicated for bleeding disorders, anticoagulants, or severe anemia
• Avoid abdomen/lower back in pregnancy; caution in menstruation
• Not for severe heart failure, renal/liver failure, or extreme edema/weakness
• Risk of burns (fire cupping), blisters (prolonged suction), or bruising; use only by qualified practitioners
• Those prone to dizziness/fainting or with malignant tumors at site should avoid

Often used for

• Chronic low back painMultiple meta-analyses (PubMed) show short-term pain reduction and improved function vs usual care; moderate quality evidence, high risk of bias common (Cochrane-style reviews note promising but limited high-quality RCTs).
• Chronic neck painMeta-analyses indicate significant pain relief and functional improvement; low-to-moderate quality evidence per recent PubMed reviews, stronger for function than pain.
• Herpes zosterChinese systematic reviews and older meta-analyses suggest higher cure rates and reduced post-herpetic neuralgia vs antivirals alone; evidence quality low, needs better trials.
• Knee osteoarthritisEvidence maps and reviews show potential pain relief; moderate quality in some metas but overall low-quality evidence.
• MigraineSystematic review and meta-analysis (PubMed 2024) supports effectiveness as complementary treatment for pain; evidence limited by study quality.
• Facial paralysis (Bell's palsy)Traditional use and some reviews show benefit when combined with acupuncture; evidence from Chinese trials, quality limited.
• AcneSystematic reviews indicate potential benefit alone or combined; low quality evidence per overviews.
• Shoulder and back musculoskeletal painCommon TCM indication; low-to-moderate evidence from metas for pain relief in sports rehab and chronic pain (PubMed reviews).
• DysmenorrheaListed in NATCM-linked platforms as applicable; small studies suggest symptom relief, evidence limited.
• Hypertension (adjunct)Some RCTs and reviews report blood pressure reduction as add-on; evidence low quality, not first-line.
• Cough and asthmaTraditional TCM application for respiratory symptoms; evidence mainly from case series and older reviews, limited modern rigor.
• IndigestionTraditional indication per NATCM verified sources; clinical observations support use, but rigorous evidence is limited.
