Where needles cool and sedate, moxa warms and nourishes — the sacred smoke of Artemisia carrying Yang back into a body that has grown cold at its core.
In the vast pharmacopoeia of Chinese medicine, few substances occupy a more revered place than Ai Ye — mugwort, Artemisia argyi. This unassuming herb, with its silver-grey leaves and faintly bitter fragrance, has been used in Chinese healing for over two thousand years. Burned near the skin over acupuncture points, it produces a distinctive penetrating warmth that travels deep into the body along the meridian pathways — reaching places that no needle can, warming patterns of cold that no herb tea can fully address.
Moxibustion (moxa) is not simply heat therapy. The distinction matters: an infrared lamp, a heat pack, or a warm water bottle all provide surface heat that remains superficial and dissipates quickly. Moxa produces a complex spectral output — including far-infrared radiation, electromagnetic fields, and the biological activity of the herb's own constituents (cineole, borneol, artemisinin) — that penetrates the acupuncture points and propagates through the meridian channels. Patients often describe feeling the warmth moving along a pathway — the classic phenomenon of Propagated Meridian Sensation — confirming what classical texts described long before we had the language to explain it.
At Rainbow Medicine, Dr Christine Shen uses moxibustion as a considered clinical tool, not a ritual addition. Its use is determined by pattern diagnosis: Yang deficiency, interior cold, dampness, and certain deficiency conditions respond beautifully to moxa. It is particularly valued in fertility care, pregnancy preparation, and the treatment of chronic fatigue, digestive weakness, and arthritis.
A compressed moxa cigar held 2–3cm above the skin, circling or hovering over acupuncture points. Generates sustained warmth without direct contact. Ideal for large areas and home practice when prescribed.
A metal cylinder containing burning moxa, applied directly to the skin surface through a protective screen. Produces intense, concentrated warmth at specific points — particularly effective for joint pain, cold in the lower abdomen, and fertility protocols.
A cone of moxa is placed on the handle of an inserted acupuncture needle and lit, transmitting heat directly along the needle shaft into the acupuncture point. Combines the precision of needling with the penetrating warmth of moxa — a particularly powerful combination for deep Yang deficiency.
Tiny cones of refined moxa placed directly on the skin at specific points, removed before burning completely. Used in classical Japanese-style practice for immune tonification (ST-36) and deep constitutional warming. Only performed with patient consent and care.
One of the most studied applications of moxibustion — and one of the most remarkable — is the use of moxa at Bladder-67 (Zhiyin), located at the outer corner of the little toenail, to encourage a breech-presenting baby to turn to head-down position. This technique, used in Chinese medicine for over a thousand years, has been the subject of multiple randomised controlled trials, including a landmark study published in the Journal of the American Medical Association (JAMA, 1998) which found that moxibustion at BL-67 significantly increased the proportion of babies who turned to cephalic (head-down) presentation compared to observation alone.
Treatment is typically offered between 33–36 weeks of pregnancy, involves daily home moxa sessions prescribed and taught by Dr Christine Shen, and is always undertaken in close communication with the woman's obstetrician or midwife. It is a gentle, non-invasive option that many women appreciate before considering external cephalic version (ECV).
Modern research has begun to illuminate the mechanisms by which moxibustion achieves its clinical effects, lending physiological substance to observations that classical practitioners made empirically over millennia.
Thermographic studies have confirmed that moxa generates heat that penetrates significantly deeper than conventional heat sources. The far-infrared spectrum emitted by burning mugwort (approximately 0.8–5.6 micrometres) corresponds closely to the absorbance spectrum of biological tissue, meaning it is preferentially absorbed and converted into thermal energy within living structures rather than merely warming the surface.
Research from Japanese and Chinese institutions has demonstrated that moxibustion at ST-36 (Zusanli), the great immune-tonifying point, stimulates the production of white blood cells — particularly neutrophils and natural killer cells — and increases levels of immunoglobulins in the blood. This supports the classical TCM use of regular moxa at ST-36 as a longevity practice and immune preventive. ("If you wish to live long, keep ST-36 moxaed," says a Tang Dynasty text.)
For fertility and obstetric applications, moxibustion has been shown to alter uterine blood flow, increase adrenal cortical activity, and influence placental oestrogen levels. The BL-67 breech-turning mechanism is thought to involve the release of prostaglandins and stimulation of adrenal hormones that increase foetal movement, combined with a direct effect on the myometrium.
Studies on moxibustion in conditions such as rheumatoid arthritis and Crohn's disease have found reductions in inflammatory markers including IL-6, TNF-alpha, and CRP following treatment courses. The herb itself — Artemisia — contains compounds with documented anti-inflammatory properties, which may be released into the skin during treatment.
In TCM, fatigue often reflects Yang deficiency — the pilot light of the body burning too low. Moxa at ST-36, CV-4, and CV-8 can restore the foundational warmth needed for metabolism, digestion, and energy production to function well.
The pattern of cold extremities despite a warm environment suggests Yang Qi failing to reach the periphery. Moxa warms the meridian channels, improves peripheral circulation, and addresses the root — often Kidney Yang or Spleen Yang deficiency — rather than merely the symptom.
A warm uterus in TCM is fundamental to conception. Moxa supports fertility by improving uterine blood flow, regulating the menstrual cycle, supporting progesterone function, and creating the energetically receptive environment in which implantation can occur.
Loose stools, bloating, abdominal cold, and poor appetite following meals reflect Spleen and Stomach Yang deficiency. Moxa at CV-12, ST-36, and SP-3 tonifies digestive Yang, improves gut motility, and restores the Spleen's transforming and transporting function.
Cold-type arthritis — pain that worsens in cold weather, improves with warmth — is a classic indication for moxibustion. Moxa disperses the Wind-Cold-Damp that has settled in the joints, improves local circulation, and reduces inflammation through both thermal and biochemical mechanisms.
Frequent colds, slow recovery from illness, and low resistance reflect Wei Qi (defensive Qi) weakness. Regular moxa at ST-36 — the great tonification point — has been used for centuries as a preventive practice, stimulating the immune response and strengthening constitutional resilience.

Moxibustion is almost always offered as part of a comprehensive acupuncture appointment rather than as a standalone treatment, though it can be prescribed as home therapy with instruction. Your session begins with the standard TCM intake — tongue and pulse diagnosis, detailed symptom history, and constitutional assessment. Dr Christine Shen will identify whether your pattern calls for the warming action of moxa and which specific points are most appropriate.
During treatment, you will notice a distinctive earthy, slightly smoky fragrance — the characteristic scent of mugwort, which many patients find deeply calming and nostalgic. Both clinics are well-ventilated to ensure comfort. The sensation of moxa is one of spreading warmth — gentle, radiant, and penetrating — distinctly different from superficial heat. Most patients find it deeply pleasant; those who run constitutionally hot may find it less comfortable, which itself provides diagnostic information.
A session may involve 15–30 minutes of moxibustion, depending on the severity of the cold pattern and the points being treated. You may be given a moxa stick and instructions for home practice between appointments — particularly for fertility protocols, where daily treatment at specific cycle phases optimises outcomes.
Contraindications include: Heat patterns or excess conditions (red, inflamed joints), high fever, active infection, pregnancy (except at specific points under supervision), and heat-sensitive skin. Dr Christine Shen will assess these considerations as part of your initial consultation.
Whether cold has settled in your joints, your energy has dimmed, or you are preparing your body for the journey of fertility — moxibustion at Rainbow Medicine offers a timeless warming medicine. Dr Christine Shen consults at Lane Cove and Freshwater.
