Where it comes from

Moxibustion is an East Asian therapeutic method that uses the heat of burning herbal preparations made from Artemisia (mugwort) to stimulate acupuncture points. It belongs to the family of traditional Chinese medicine, a system that has evolved over thousands of years. The material, called moxa, is dried mugwort that is aged and ground into a fluff, then burned as small cones or rolled into a cigar-like stick.

The practice spread across East Asia: in Chinese it is called ài (艾), in Japanese the plant is yomogi, and Korean folklore has its own origin story for it. The first Western descriptions came from Portuguese missionaries in 16th-century Japan, and the first Western book on the subject, by Hermann Buschoff, was published in 1674.

Today most research on moxibustion comes from China. Independent reviews describe much of it as low quality, with one notable exception: turning breech babies, where a 2023 Cochrane review found moderate-certainty evidence of an effect.

The principle

The idea is to apply warmth to chosen acupuncture points rather than needles. The heat can range from gentle warming of the skin to, if overdone, tissue damage; researchers note that heat on the skin triggers local inflammatory and blood-vessel responses.

The best-studied example is a point on the little toe (Bladder 67) used late in pregnancy: the warmth is meant to stimulate the uterus and encourage a breech baby to turn head-down. For most other uses, an overview of systematic reviews concluded that considerable uncertainty remains about its therapeutic value.

How it works on the body

Moxibustion works through heat placed on or near the skin over specific points, sometimes combined with acupuncture needles.

A session, step by step

01
Health check
Tell the practitioner about your medical conditions, pregnancy and any medicines you take before treatment starts.
02
Choosing the points
The practitioner selects the points to warm, depending on the tradition and your reason for coming.
03
Indirect moxa
Most often a lit moxa stick is held a short distance above the skin, or a small cone is placed on top of an acupuncture needle to warm it.
04
Direct moxa
Some styles place a small moxa cone on the skin and remove it before it burns; a traditional scarring form also exists, so ask in advance which method is used.
05
Aftercare
Check the skin afterwards for redness or blisters. For breech, some practitioners teach a partner to apply moxa at home, which requires care to avoid burns.

Precautions

Moxibustion carries a real risk of burns and skin infection; say immediately if the heat feels too strong.
In pregnancy, use it only with your midwife's or doctor's agreement: studies report contractions, increased fetal movement, nausea, headache and burns, and safety reporting was poor.
If your skin has reduced sensation, is broken, or has an infection or skin condition, ask a doctor first.
It does not replace medical care: see a doctor for symptoms that persist, return or worsen, and do not stop prescribed medicines.

Complementary practice: does not replace medical advice.

In Thailand

In Thailand moxibustion belongs to the Chinese medicine tradition. Chinese medicine (การแพทย์แผนจีน) is one of the healing-art professions licensed by the Ministry of Public Health under the Healing Arts Practices Act B.E. 2542 (1999), supervised by the Division of Health Facilities and Healing Arts of the Department of Health Service Support; as of 30 September 2025 the division counted 2,370 licensed Chinese medicine practitioners. Anyone can check a practitioner's licence on the division's online register.

Frequently asked questions

Does moxibustion hurt?

It should feel warm, not painful. Burns are the main reported risk, so tell the practitioner straight away if it becomes too hot.

Does it actually work?

Evidence is strongest for turning breech babies (moderate certainty in a 2023 Cochrane review, without a clear drop in caesarean sections). For other conditions, the studies are mostly low quality and the benefit is uncertain.

Is it the same as acupuncture?

Not exactly. It uses the same points but relies on heat rather than needles, although the two are sometimes combined by placing moxa on a needle.

Can I do it at home?

In breech studies, women or their partners applied moxa at home after instruction, and burns from holding the stick too close were reported. Only do this with guidance and with your midwife's or doctor's agreement.
