Back to Acupuncture Methods: Manual, Electro- and Auricular Acupuncture and AcupressureWhat these methods are
Heat is added to acupuncture in several ways. This page covers the ones with research, described only in general terms and with no instructions for doing them.- Warm needle acupuncture places an ignited moxa stick (a burning herb) on the handle of a needle after it has been inserted. [1] The herb is mugwort-based moxibustion, which has its own page: Moxibustion.
- Fire needling heats the tip of a needle until it is red-hot and then inserts it quickly into the skin lesion. [2]
- Heat lamps (often sold as "TDP lamps") are also used near the skin. Proper evidence not found: we searched for trials of heat or infrared lamps with acupuncture and did not find a usable review to cite.
Traditional explanation versus research
Practitioners in China use these techniques, and warm needle acupuncture is commonly used for osteoporosis there. [1] The idea that warmth strengthens the treatment is a traditional belief and was not tested by the reviews below; they only compare outcomes with other treatments. The same review described the claim as anecdotal. [1]What reviews found
Evidence labels: insufficient evidence and promising but limited. Nearly all trials were in China, many were not blinded, and most compared heat plus another treatment with that treatment alone, so extra heat is hard to separate from extra attention or expectation.| Method and use | What the review found | Label |
|---|---|---|
| Warm needle, osteoarthritis | 66 trials. Better total effective rate than oral drugs and equal to hyaluronate injections. Most trials had unclear risk of bias and certainty was very low. No serious adverse events reported. [3] | Insufficient evidence |
| Warm needle, osteoporosis | 9 trials, 572 people. Bone density measures improved when used with usual medicine, but all trials were at high risk of bias and safety was not specifically reported. [1] | Insufficient evidence |
| Fire needle, acne | 10 trials, 904 people. Better than drugs on the effective rate, with no difference in recurrence. [4] | Promising but limited |
| Fire needle, psoriasis | Added to Chinese herbal medicine, it did better than herbs alone on skin scores and recurrence. [5] | Insufficient evidence |
| Fire needle, mouth ulcers | 9 trials, 1,469 people. Pain and healing time improved, recurrence did not differ, and the authors raised concerns about trial quality. [6] | Insufficient evidence |
| Fire needle, neurodermatitis | Alone, no better than usual treatment. Combined with usual treatment, it did better on several measures. Methods had flaws. [2] | Insufficient evidence |
Burns and other risks
Burns are the main concern with any heat method, because the heat sits on or near the skin. In the fire needle trials we read, adverse events were reported for skin reactions: the acne review described burning and tingling as brief. [4] A neurodermatitis review found redness, burning sensation, bleeding and skin peeling, mostly mild, but only four studies reported adverse events at all, so the true rate is unclear. [2] We did not find a review measuring burn or infection rates for fire needling. General acupuncture risks include infection and organ injury when not delivered properly. [7]For burns from moxa and cupping, see Moxibustion and Cupping Risks. Combined treatments are explained in Acupuncture Combined With Cupping, Moxibustion and Other Adjuncts.
Who should take extra care and when to get care
Heat methods are not for self-treatment. People with reduced skin sensation, diabetes, poor circulation, skin disease in the treated area, bleeding problems or implanted devices should ask their own clinician first; we did not read heat-specific guidance on these groups. Get medical care for a blister, spreading redness, pus, fever or pain that is getting worse after any treatment. Use a licensed practitioner: Acupuncture Practitioner Licensing and Training by Jurisdiction.Frequently asked questions
What is a warm needle?
A needle with an ignited moxa stick placed on its handle after insertion. [1]
What is fire needling?
A needle tip heated until red-hot and quickly inserted into the skin. [2]
Does fire needling work for acne?
A review of 10 trials found better effective rates than drugs, with brief burning and tingling. Evidence is promising but limited. [4]
Is it safe?
Reviews reported mostly mild reactions, but few trials reported safety, and burns are a known concern with heat. We did not find burn-rate data for fire needling. [2]
Do TDP heat lamps work with acupuncture?
Proper evidence not found. We searched for trials and found no usable review.
