TCM in China

Moxibustion: heat, smoke, and a list of people who should skip it

Of all the TCM techniques, this is the one with a published set of cautions that is unusually specific — and unlike cupping or scraping, the main practical nuisance is airborne. You are sitting in smoke, and the heat source is a burning cone.

Reviewed 2026-09-21. The cautions and dose guidance below are quoted from Chinese municipal health authority patient information, cited at the foot of this page. This is general information, not medical advice.

What is being done

Moxa is dried mugwort, and moxibustion is burning it at or near the skin so that heat — and smoke — reach the area. In Chinese practice it is broadly divided by how the burning moxa is held in relation to the body:

• Moxa cones, either placed directly on the skin or with something in between — a slice of ginger, garlic, salt or a cake of processed herbs. The interposed layers are where most of the named variants come from.
• Moxa sticks, held a few centimetres above the skin and either kept still, moved in pecks, or swept back and forth.
• Warm needling, where a needle is inserted first and a section of burning moxa is mounted on the needle handle so heat travels down it. This combines two techniques and is priced as needle work.
• Moxibustion devices — boxes and cylinders that hold the burning moxa against a larger area. This is the version most compatible with doing at home, and the version where you have least feedback about how hot the skin is getting.

In the provincial price schedules the plain hospital item is suspended moxibustion (悬空灸), defined as holding the burning material at a fixed distance from the skin and using gentle warmth and the action of the moxa together.

The smoke is a real issue, not a detail

Moxa produces visible smoke and volatile compounds, and Chinese health authorities treat this as something to manage rather than ignore. Their own patient advice:

• Keep the room ventilated while maintaining warmth — ventilation without a draught on the body.
• Use good quality aged moxa, specifically to reduce the content of moxa smoke and its volatiles. Older, well-stored moxa is the recommendation over fresh.
• Smokeless and electronic moxibustion devices exist and are described by a municipal health authority as a workable alternative for people who cannot tolerate the smoke — with the caveat that a device is not the same product as burning moxa.

If you have asthma or another respiratory condition, or you simply react badly to smoke, the ventilation of the room is not a side matter you can overlook for an hour. Ask whether a room with working extraction is available, or ask for one of the alternatives.

How much is too much

Chinese patient guidance gives unusually concrete limits, which is useful because moxibustion is the technique most often self-administered at home:

• About three times a week.
• No more than three areas in one session.
• About 20 minutes per area as a working maximum.

The stated goal is warmth the person finds comfortable and skin that goes slightly pink — not skin that is being pushed. The guide's own summary is that moxibustion "must not be excessive".

Burns and blisters

Published handling advice is specific, and it distinguishes between a minor reaction and a burn:

• A small blister should not be punctured. Cover it with clean gauze, keep it clean and dry, avoid friction, and it will normally resolve in about a week.
• A large blister, or a burn, should be assessed and treated at a hospital rather than managed at home.
• Graying or pigmentation at the treated site is described as an ordinary consequence and fades over months rather than days.

The form that deliberately blisters

Scarring moxibustion (瘢痕灸) and blistering moxibustion (发泡灸) are intended to produce a burn that forms a sore and then heals. This is not a stronger version of a pleasant warm treatment — it is a deliberate wound, and it is treated that way in the rules.

Chinese health-supervision guidance lists scarring moxibustion and blistering moxibustion among the techniques that non-medical establishments must not use. If a spa offers you either, the problem is not the price. The safety page covers how to check a licence quickly.

What people report afterwards

Municipal health authority information notes that after repeated moxibustion some people experience dryness — dry mouth, throat, eyes, nose — or a runny nose, or changes in sleep and bowel habit. Those reactions are described as usually mild, resolving in a day or two of rest. Some of them are framed in the source as signs the treatment is taking effect; the safer way to read it is simply as a common reaction that settles on its own.

What the same guidance is clear about is that you should not keep going regardless. If something is worsening rather than settling, the advice is to see a doctor rather than continue the sessions.

What it costs

The gap between ¥38 and ¥73.80 for the same named item is the province-level pricing system at work, not an error in either document — and the ¥270 entry shows how far a more elaborate spine protocol can move the number.

The honest version

Moxibustion is the low-tech end of TCM and the least likely of these techniques to break your skin — which is exactly why so much of it happens at home and in wellness settings. The genuine risks are burns and, for some people, the smoke.

If you are pregnant, breastfeeding is not the issue but pregnancy is — ask before, not during. If you have diabetes or reduced sensation in your feet, treat any moxibustion offer as something to discuss with a clinician who knows your feet, and do not accept a home session from anyone who has not asked about it.
