Types of Moxibustion: Direct, Indirect & Modern Methods Guide
What are the main types of moxibustion?
Moxibustion divides into two primary categories: direct and indirect. Direct moxibustion places a moxa cone on the skin; indirect methods interpose a medium or use a stick held above the point. Modern adaptations add electric and smokeless devices to the classification.
The World Health Organization and classical Chinese texts organise moxibustion into these two fundamental groups based on skin contact [1]. Within each category, specific techniques diverge according to the material used, the duration of burning, and the desired therapeutic intensity.
Moxibustion Classification at a Glance
| Main Category | Subtype | Skin Contact | Scarring Risk |
|---|---|---|---|
| Direct | Scarring | Full – cone burns down onto skin | Yes |
| Non‑scarring | Partial – cone removed before burn | No | |
| Indirect | Moxa stick (suspended) | None – 2–4 cm distance | No |
| Ginger‑partitioned | Via ginger slice | No | |
| Salt‑partitioned (navel) | Via salt layer | No | |
| Needle‑top (warming needle) | Via acupuncture needle handle | No |

How does direct moxibustion differ from indirect moxibustion?
Direct moxibustion applies a smoldering cone onto the skin, creating intense local heat and sometimes a blister or scar. Indirect moxibustion keeps the heat source separated from the skin by a medium or distance, delivering milder, evenly distributed warmth without breaking the skin.
Indirect moxibustion carries a significantly lower burn risk than direct moxibustion and does not produce scarring. A review of 64 adverse‑event cases confirms that direct scarring moxibustion accounts for the majority of serious burns, while indirect methods are associated with fewer thermal injuries [2].
The distinction hinges on two factors: the temperature peak at the dermis and the exposure time. Direct moxa cones can raise the skin surface to over 60°C, activating nociceptors that trigger an inflammatory blister. Indirect moxa sticks, held at 3–4 cm, maintain a safer range of 40–47°C [3].
What is direct scarring moxibustion?
Direct scarring moxibustion burns a small moxa cone completely on the skin until a blister forms and eventually scars. Practitioners select rice‑sized cones for minute, intensely hot points, often at ST36 or CV4, to deliver a potent, sustained immune response.
Scarring moxibustion causes a third‑degree thermal burn intentionally. It must be performed only by experienced practitioners with strict sterilisation protocols because of the infection risk. This technique is contraindicated for cosmetic areas, patients with keloid tendencies, and those with impaired healing [4].
For a detailed comparison of scarring and non‑scarring techniques, including grade levels and cone sizing, read our dedicated guide on direct moxibustion.
What is non‑scarring direct moxibustion?
Non‑scarring direct moxibustion ignites a cone on the skin but removes it just as the patient feels a sharp heat, before a blister forms. This technique achieves deep thermal stimulation without permanent skin damage, making it suitable for children, elderly, and those averse to scars.
The practitioner monitors the patient’s verbal feedback continuously and extinguishes the cone with a swift pinch. Non‑scarring direct moxibustion is classified as a “warming and tonifying” method, frequently chosen for chronic deficiency patterns in traditional Chinese medicine [5].

What is moxa stick moxibustion?
A moxa stick is a cigar‑shaped roll of compressed mugwort wool. The practitioner ignites one end and holds it 2–3 cm above an acupoint, employing sparrow‑pecking or circling motions. This suspended indirect method is the most common form used in clinics and at home.
Moxa sticks burn at a steady rate of approximately 3–5 mm per minute, and a typical session lasts 15–20 minutes per point. Smokeless sticks reduce airborne particulates by over 90% compared to traditional moxa, making them preferable for poorly ventilated spaces [6].
To compare the heat intensity, handling characteristics, and therapeutic profiles of moxa sticks and cones, see our guide on moxa stick vs moxa cone.
How does ginger‑partitioned moxibustion work?
Ginger‑partitioned moxibustion places a thin, fresh ginger slice on the acupoint and a moxa cone on top. The ginger absorbs and evenly distributes heat while adding its own pungent, warming properties that disperse cold and invigorate the middle burner in TCM theory.
This technique typically combines with non‑scarring direct cones: the ginger is perforated to allow heat to penetrate. Studies show ginger‑partitioned moxibustion reduces nausea and abdominal pain effectively, correlating with increased local blood flow and modulation of 5‑HT3 receptors [1].

What is salt‑partitioned moxibustion (navel moxibustion)?
Salt‑partitioned moxibustion fills the navel (acupoint CV8) with clean salt, then burns a moxa cone on top. The salt insulates and diffuses heat deep into the abdomen, treating diarrhoea, abdominal pain, kidney‑yang deficiency, and gynaecological cold‑pattern disorders.
The salt must be dry and fine‑grained; coarse sea salt that dissolves in sweat can cause irritation. This method is contraindicated during acute abdominal inflammation or in pregnancy [4].
To compare salt‑partitioned therapy with other indirect techniques, read indirect moxibustion.
What is warming needle moxibustion?
Warming needle moxibustion attaches a small moxa ball to the handle of an inserted acupuncture needle. As the moxa smoulders, heat conducts down the metal shaft into deeper tissues, simultaneously providing acupuncture stimulation and thermal therapy at the same point.
This technique intensifies needling sensation and is often selected for chronic pain, arthritis, and Bi‑syndrome (painful obstruction). Safety demands a protective disc or guard to prevent ashes from falling onto the skin [3].

How do modern moxibustion methods compare to traditional techniques?
Modern methods include electric moxibustion devices that deliver infrared heat without smoke, and handheld TDP lamps that mimic moxa’s far‑infrared spectrum. These devices eliminate combustion by‑products and lower burn risk substantially, though they lack the pharmacological actions of artemisinin vapour.
Electric moxa devices operate at a precisely controlled temperature range of 40–50°C and are often preferred in hospital settings because they do not produce smoke that can trigger fire alarms. However, a 2023 comparative study found that traditional moxa sticks generated significantly higher pain reduction for knee osteoarthritis than an electric infrared device, suggesting the contribution of non‑thermal factors [1].
Traditional vs. Modern Moxibustion
| Feature | Traditional (moxa stick) | Modern (electric/infrared) |
|---|---|---|
| Heat source | Burning Artemisia vulgaris | Electric element / carbon fibre |
| Smoke production | Yes – significant | None |
| Chemical constituents | Artemisinin, volatile oils | None |
| Burn risk | Moderate (3rd degree possible) | Very low |
| Temperature control | Manual – distance adjustment | Thermostatic – digital setting |
| Evidence strength | Moderate (Cochrane) for breech | Limited comparative trials |

Which type of moxibustion is safest for beginners?
Smokeless moxa sticks or an electric moxa device offer the lowest risk for home users. They require no contact with the skin and produce minimal smoke. Beginners must still maintain a 2–3 cm distance and always extinguish the stick completely after each session.
For those learning with a practitioner, non‑scarring direct moxibustion under supervision provides a controlled introduction. Avoid direct scarring moxibustion and ginger‑partitioned methods until you master distance control and sensation judgement.
