11.5 Moxibustion: Mediums, Methods, and Safety

11.5 Moxibustion: Mediums, Methods, and Safety

Quick Answer: Adjunctive modalities expand clinical efficacy beyond manual needling. Moxibustion (Jiu Fa) burns dried mugwort leaf (Ai Ye, Artemisia argyi) to deliver radiant heat that warms the channels, dispels cold, stops bleeding, and restores Yang. Indirect moxibustion utilizes specific mediums: salt at Ren 8 (Yang collapse, diarrhea), ginger (cold vomiting/diarrhea), garlic (scrofula, boils, insect bites), and monkshood/Fu Zi (deep Kidney Yang failure). Moxa is contraindicated in Excess Heat and Yin Deficiency Heat. The 2026 ACPL outline gives moxibustion 5% of the exam: identify its indications, precautions, and contraindications, select the appropriate technique (direct, indirect, warming needle), and adjust it to the patient's response. Cupping, gua sha, and bloodletting follow in Section 11.6, and electroacupuncture, heat lamps, Tuina, and acupressure in Section 11.7.

Moxibustion (Jiu Fa): Pharmacology, Mediums, and Methods

Moxibustion is the therapeutic application of thermal energy generated by combusting dried leaves of Artemisia argyi (Ai Ye, Chinese mugwort; Western texts often say A. vulgaris). In Chinese pharmacology, Ai Ye is acrid, bitter, and warm, possessing affinities for the Liver, Spleen, and Kidney meridians. When burned, it produces steady radiant heat, much of it infrared.

1. Modalities of Moxibustion

• Direct Moxibustion (Zhi Jie Jiu): Small moxa cones placed directly upon the bare skin.
  • Scarring Moxa (Hua Hen Jiu): The cone is allowed to burn completely down to the skin, causing a local second-degree burn, blister, and eventual suppurative healing scar. Classically indicated for severe chronic refractory asthma, systemic debility, and intractable tuberculosis. Rarely used in modern Western practice due to legal and infection risks.
  • Non-Scarring Moxa (Wu Hua Hen Jiu): The cone is ignited on the skin but removed or extinguished with tweezers when 70% to 80% consumed, once the patient reports a sharp, localized heat sensation. Leaves no blister or permanent scar.
• Indirect Moxibustion with Mediums (Jian Jie Jiu):
  • Ginger Moxa (Sheng Jiang Jiu): A fresh slice of ginger root (0.2 to 0.3 cm thick, pricked with needle holes) is placed on the point, and a moxa cone is burned atop it. Combines heat with the acrid, warming action of ginger. Indicated for Spleen-Stomach Cold deficiency, nausea, cold abdominal pain, diarrhea, and painful joints (Cold Bi).
  • Garlic Moxa (Da Suan Jiu): A slice of fresh garlic is placed over the lesion or point. Garlic is warm, resolving toxins and dispersing swellings. Indicated for scrofula (cervical lymphadenitis), early-stage skin carbuncles and boils without ulceration, and insect bites.
  • Salt Moxa (Yan Jiu): Pure dry table salt fills the umbilicus (Ren 8 / Shenque) level with the abdominal skin, topped with a thin slice of ginger or a moxa cone. Indicated for acute Yang collapse, shock, profound hypotension, profuse diarrhea, and severe abdominal cramping from cold.
  • Monkshood / Aconite Cake Moxa (Fu Zi Bing Jiu): A prepared cake of powdered aconite mixed with yellow wine. Monkshood is intensely warm and enters the Kidney to revive Yang. Indicated for Kidney Yang deficiency, Mingmen exhaustion, impotence, chronic diarrhea, and chronic carbuncles that form persistent cold, non-healing ulcerations.
• Warm Needle Moxibustion (Wen Zhen Jiu): A 1.5 to 2.0 cm segment of a moxa roll is impaled onto the handle of a previously inserted metal needle and ignited. Thermal energy conducts down the metal needle shaft directly into deep articular structures. Premier modality for Cold-Damp Bi syndrome, osteoarthritis, and chronic tendonitis.
• Moxa Stick / Cigar (Ai Tiao Jiu): Combustion of a compressed paper-wrapped moxa cylinder held 2 to 3 cm above the skin.
  • Mild-Warm Moxa (Wen He Jiu): Held statically to impart steady, gentle warmth.
  • Sparrow-Pecking Moxa (Que Zhuo Jiu): Moved rapidly up and down like a pecking bird to deliver dynamic thermal bursts.
  • Circular Moxa (Hui Xuan Jiu): Moved in broad circular sweeps over large painful areas.

2. Contraindications to Moxibustion

• Excess Heat and Yin Deficiency Heat Patterns: Patients presenting with high fever, red face, thirst with desire for cold drinks, rapid forceful pulse, or night sweats, hot flashes, and red tongue with peeled coating must not receive moxibustion. Adding heat to heat accelerates fluid depletion and stirs wind.
• Sensitive Facial and Cranial Regions: Direct or intense moxibustion is forbidden on the face, near the eyes, or adjacent to sensory orifices to prevent burns, smoke irritation, and facial scarring.
• Over Major Superficial Blood Vessels: Never apply direct moxa over prominent arteries (e.g., carotid artery at ST 9, radial artery at LU 9).
• Pregnancy: Moxibustion is prohibited on the abdomen and lumbosacral region throughout pregnancy.
• Neuropathic Sensation Loss: Patients with diabetic peripheral neuropathy, spinal cord injuries, or advanced vascular disease cannot accurately gauge heat intensity, leading to high burn risk.

3. Management of Moxa Burns

• First-Degree Burns (Erythema): Apply cold compresses, followed by an application of burn ointment (e.g., Ching Wan Hung) or pure aloe vera. Keep skin clean and dry.
• Small Blisters (< 1 cm diameter): Do not puncture or de-roof the blister. Protect the blister with sterile gauze; it will reabsorb naturally within 3 to 7 days.
• Large Blisters (> 1 cm diameter): Under strict aseptic technique, cleanse the blister with an antiseptic swab, puncture the blister margin at its lowest gravitational point with a sterile needle, gently express the serous fluid with a sterile cotton swab while keeping the epidermal roof intact, and apply antibiotic ointment with a non-adherent sterile dressing.

Adjusting Moxibustion to the Patient's Response

Moxibustion is dosed by the patient's feedback. With direct non-scarring cones, remove the cone as soon as the patient reports strong heat. With a moxa stick, move it farther away or shift to sparrow-pecking if the skin reddens quickly. Moxa smoke can trigger coughing or wheezing, so use smokeless moxa or good ventilation for asthmatic patients. Stop if the patient becomes flushed, thirsty, or agitated, which suggests that heat is aggravating a Heat pattern. Record the number of cones or the minutes applied so that the dose can be repeated or adjusted at the next visit.
