Moxibustion 艾灸

What it is

The Chinese term for the needle art is zhēn jiǔ — "needling and burning" — and moxibustion is the burning half, older by most accounts than the needles^[1]. Dried mugwort (Artemisia argyi, ài yè) is compressed into sticks, cones, or loose wool and burned near or on acupuncture points: a glowing "moxa cigar" held above the skin, a cone on a slice of ginger or a layer of salt, or a pinch riding the handle of an inserted needle. The tradition reads the deep, penetrating warmth as adding yang — its uses cluster around cold and deficient patterns: cold joints and low backs, weak digestion, exhaustion, and prevention (the famous longevity point Zusanli was moxa'd, not needled)^[1].

What the evidence says

Moxibustion owns one genuinely famous corner of the research literature: turning breech babies. Burning moxa at the tip of the fifth toe (point BL67) has been tested in randomized trials for encouraging a head-down position, and the Cochrane review — updated in 2023 — concludes moxibustion may reduce the need for manual version and finds suggestive but not definitive benefit, with the usual call for better trials^[2]. Beyond obstetrics, trials exist for pain and digestive conditions but are generally small and of modest quality — a familiar verdict in this field.

Safety basics

The obvious one: it is fire. Burns and scarring are the real risks — traditional "scarring moxibustion" burned deliberately, which modern practice largely abandoned — plus smoke sensitivity in closed rooms. Done by a trained practitioner with indirect technique, it is among the gentler procedures in the toolkit. Pregnant women should only receive it from a qualified professional, breech protocol included.

Where it sits in the grove

Moxibustion is why mugwort (ài yè) will eventually earn its own drawer in the herb cabinet, and why the smell of burning ài yè is, for much of Asia, simply the smell of a clinic. Paired reading: what is qi? for the framework the warmth is said to serve.
