TL;DR: Ai Jiu therapy—also known as moxibustion—is a Traditional Chinese Medicine practice that uses the burning of dried mugwort (moxa) near or on the skin to stimulate healing. Modern research suggests it may help with pain relief, immune function, digestive health, and more, making it a compelling complement to conventional care.

Walk into any Traditional Chinese Medicine (TCM) clinic and you’ll likely notice an earthy, distinctive smell. That’s moxa—dried mugwort—being burned as part of Ai Jiu therapy, one of the oldest healing practices in recorded history. Dating back over 2,500 years, this technique has been documented in ancient Chinese medical texts and remains a cornerstone of TCM practice to this day.

What’s remarkable is that Ai Jiu therapy hasn’t simply survived the test of time—it’s gaining traction in Western wellness circles, integrative medicine clinics, and academic research settings. As more people look beyond pharmaceutical-first approaches to health, practices like Ai Jiu are attracting serious scientific attention. Researchers are now examining how heat, herbal compounds, and acupoint stimulation interact with the body to produce measurable therapeutic effects.

This post covers everything you need to know about Ai Jiu therapy: what it is, how it works, what conditions it may address, and how to approach it safely. Whether you’re curious about complementary health practices or actively exploring options for chronic pain, fatigue, or digestive issues, this guide will help you make an informed decision.

What Is Ai Jiu Therapy, and How Does It Work?

Ai Jiu (艾灸) translates literally to “moxa cauterization” in Chinese. The practice involves burning compressed mugwort—a herb known botanically as Artemisia argyi or Artemisia vulgaris—either directly on or near specific points on the body called acupoints. These acupoints correspond to pathways called meridians, through which, according to TCM theory, vital energy known as qi flows.

From a traditional standpoint, Ai Jiu therapy at Kelly Oriental works by warming the meridians, expelling cold and dampness, and promoting the smooth circulation of qi and blood. Illness, in TCM philosophy, is often linked to stagnation or imbalance in this flow. The heat from burning moxa is believed to penetrate deeply into tissue, reaching beyond what surface-level warmth can achieve.

Western researchers offer a complementary lens. Studies suggest that moxibustion triggers localized vasodilation, increases circulation, stimulates the release of heat shock proteins, and activates transient receptor potential (TRP) channels—biological pathways involved in pain perception and inflammation. The smoke and volatile compounds released during moxa combustion, including cineole and borneol, may also contribute to its effects through inhalation and skin absorption.

What Are the Different Types of Ai Jiu Therapy?

Practitioners use several distinct methods, each suited to different conditions and patient needs:

• Direct moxibustion: A small moxa cone is placed directly on the skin at an acupoint and burned. This method is more intense and less commonly used in modern clinical settings due to the risk of scarring.
• Indirect moxibustion: The most widely used form today. A moxa stick is held near the skin—typically 1 to 3 centimeters away—and moved in circular or up-and-down motions to apply warmth without direct contact.
• Moxa on needle: Moxa is placed on the tip of an acupuncture needle that has already been inserted, combining the benefits of both therapies.
• Salt or ginger moxibustion: Moxa is burned on a layer of salt or a slice of ginger placed over an acupoint. This variation is common for digestive and cold-related conditions.
• Heat lamp moxibustion: A smokeless, modern adaptation that uses infrared or moxa-infused lamps. Often preferred in clinics with ventilation constraints.

What Conditions Can Ai Jiu Therapy Help Treat?

The evidence base for Ai Jiu therapy spans a wide range of health concerns. While research quality varies—and it’s important to note that many studies are preliminary—the clinical findings are increasingly hard to dismiss.

Can Ai Jiu Therapy Relieve Chronic Pain?

Pain management is one of the most studied applications of moxibustion. A systematic review published in Evidence-Based Complementary and Alternative Medicine found that moxibustion provided statistically significant pain relief for patients with knee osteoarthritis compared to control groups. Other studies have explored its effects on lower back pain, neck pain, and fibromyalgia, with results suggesting that regular treatment can reduce both pain intensity and reliance on analgesic medication.

The mechanism appears to involve a combination of heat-induced muscle relaxation, improved blood flow to affected areas, and modulation of pain-signaling pathways in the nervous system.

How Does Ai Jiu Therapy Support Digestive Health?

In TCM, many digestive complaints—including irritable bowel syndrome (IBS), bloating, and poor appetite—are attributed to “spleen qi deficiency” or “cold in the stomach.” Ai Jiu therapy applied to acupoints such as ST36 (Zusanli) and CV12 (Zhongwan) is a traditional approach to these issues.

Research backs this up to a degree. A clinical trial published in the World Journal of Gastroenterology found that moxibustion at ST36 significantly improved symptoms and quality of life in patients with Crohn’s disease compared to medication alone. Separate studies have shown improvements in gut motility and reduced inflammation markers in IBS patients following moxibustion treatment.

Can Moxibustion Support Immune Function?

ST36—the acupoint located just below the knee—is arguably the most studied point in moxibustion research. Traditional texts describe it as a master point for tonifying the body’s overall vitality. Modern studies suggest there’s something to this: moxibustion at ST36 has been shown in several animal and human studies to increase white blood cell count, elevate natural killer cell activity, and upregulate interleukin production, all of which are markers of enhanced immune response.

For cancer patients undergoing chemotherapy, some integrative oncology programs have incorporated moxibustion as a supportive therapy to counteract treatment-induced immunosuppression, fatigue, and nausea.

What Role Does Ai Jiu Play in Women’s Health?

One of the most well-known applications of moxibustion in the West is the correction of breech presentation in late pregnancy. A landmark study published in the Journal of the American Medical Association (JAMA) in 1998 found that moxibustion at acupoint BL67 (Zhiyin) significantly increased fetal activity and the rate of cephalic (head-down) presentation compared to a control group.

Beyond pregnancy, Ai Jiu is frequently used by TCM practitioners for menstrual irregularities, dysmenorrhea (painful periods), and menopausal symptoms. The warming nature of the therapy is considered particularly beneficial for conditions associated with “cold uterus” in TCM.

How Does Ai Jiu Therapy Address Fatigue and Low Energy?

Chronic fatigue—whether linked to burnout, post-illness recovery, or age-related decline in vitality—is another common reason people seek out Ai Jiu. TCM attributes fatigue to deficiencies in qi and yang energy, and moxa’s warming action is specifically designed to replenish these reserves.

Practitioners typically target points like CV4 (Guanyuan), CV6 (Qihai), and ST36. Some practitioners recommend seasonal moxibustion during the transition to autumn and winter as a preventive measure to strengthen the body ahead of the colder months.

What to Expect During an Ai Jiu Therapy Session

If you’re new to Ai Jiu therapy, knowing what to expect can ease any apprehension. Sessions typically begin with a consultation—your practitioner will ask about your health history, current symptoms, and constitution according to TCM principles. This informs which acupoints will be used and which method of moxibustion is most appropriate.

During the session, you’ll lie on a treatment table, and the practitioner will apply moxa heat to the selected points. Most people describe the sensation as deeply warming and pleasant—similar to a heating pad, but more penetrating. Sessions generally last between 30 and 60 minutes. The room will have a distinctive herbal smell from the moxa smoke, though smokeless alternatives are increasingly available.

Side effects are rare but can include mild skin redness, temporary dizziness (especially in those who are highly sensitive to heat), or a slight aggravation of symptoms before improvement. These effects are typically short-lived.

How to Choose a Qualified Ai Jiu Practitioner

Ai Jiu therapy should always be administered by a trained practitioner, particularly for internal or therapeutic applications. Look for:

• A licensed acupuncturist or TCM practitioner: In the US, look for credentials from the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM).
• Experience with moxibustion specifically: Not all acupuncturists routinely practice Ai Jiu. Ask directly about their training and frequency of use.
• A clean, well-ventilated clinic: Moxa smoke can be irritating, particularly for those with respiratory conditions. Reputable clinics will have proper ventilation or offer smokeless options.

Avoid self-administering direct moxibustion without professional guidance. Indirect moxa sticks are more commonly sold for home use, but even these carry a burn risk and should be used with care.

Is Ai Jiu Therapy Right for You?

Ai Jiu therapy is not a universal solution, and it’s not intended to replace conventional medical care for serious conditions. Choose Ai Jiu therapy if warmth-responsive symptoms, chronic pain, digestive complaints, or fatigue are central concerns and you’re open to complementary approaches. It’s particularly well-suited for individuals who feel cold easily, have poor circulation, or have found limited relief from other interventions.

Those who should avoid moxibustion or consult a doctor first include pregnant women (outside of the specific supervised use for breech presentation), people with heat-sensitive conditions, individuals with compromised skin integrity, and anyone running a fever.

The Takeaway on Ai Jiu Therapy

Thousands of years of use and a growing body of scientific evidence suggest that Ai Jiu therapy is far more than a cultural relic. It’s a nuanced, targeted practice that addresses some of the most common complaints people bring to both TCM practitioners and conventional physicians—pain, fatigue, digestive dysfunction, and immune vulnerability.

The best approach is an informed one. Talk to a licensed TCM practitioner to assess whether Ai Jiu therapy aligns with your health profile, and treat it as part of a broader wellness strategy rather than a standalone cure. The heat may be ancient, but the benefits are very much relevant today.

Frequently Asked Questions About Ai Jiu Therapy

What is the difference between moxibustion and acupuncture?
Acupuncture uses thin needles inserted at specific acupoints to stimulate qi flow. Ai Jiu therapy uses heat from burning mugwort at the same points. The two therapies are often used together and share the same theoretical framework, but they are distinct techniques with different mechanisms and applications.

How many Ai Jiu sessions are needed to see results?
This varies depending on the condition being treated and the individual’s response. For acute conditions, improvement may be noticed after 1–3 sessions. Chronic conditions typically require a series of 6–12 sessions, often scheduled weekly or twice weekly. Your practitioner will reassess and adjust the treatment plan as needed.

Is Ai Jiu therapy safe during pregnancy?
Most moxibustion points are avoided during pregnancy due to potential stimulating effects on the uterus. The exception is the use of BL67 for breech presentation correction in the third trimester, which should only be done under the supervision of a qualified practitioner. Always disclose pregnancy to your TCM provider.

Can I do moxibustion at home?
Moxa sticks designed for home use are widely available, but home use carries risks including burns, fire hazard, and incorrect point selection. If you’re interested in home practice, have a practitioner train you first and stick to indirect methods only.

Does Ai Jiu therapy hurt?
When performed correctly, Ai Jiu therapy is not painful. Most people find the warmth deeply relaxing. You should feel comfortable heat, not burning or stinging. If you experience discomfort, tell your practitioner immediately so the distance or intensity can be adjusted.

Is there scientific evidence supporting Ai Jiu therapy?
Yes, though the quality and volume of evidence varies by condition. The strongest evidence currently exists for pain management, breech presentation correction, and digestive conditions such as Crohn’s disease and IBS. Research is ongoing, and Ai Jiu therapy is increasingly studied within integrative medicine frameworks.
