Key Finding
Moxibustion significantly reduced arthritis severity in animal models with large effect sizes (SMD -3.72 for arthritis index) while suppressing pro-inflammatory cytokines and key signaling pathways including NF-κB and NLRP3 inflammasome.
Moxibustion is a traditional Chinese medicine therapy that uses burning mugwort (Artemisia argyi) to warm specific points on the body. It has been traditionally used to treat "Bi Zheng," a condition similar to rheumatoid arthritis (RA), a chronic inflammatory disease causing joint pain, swelling, and damage. Researchers conducted a comprehensive review of 73 animal studies to evaluate whether moxibustion could reduce arthritis symptoms and understand how it works. The meta-analysis examined its effects on arthritis severity, swelling, tissue damage, and inflammatory markers in laboratory models of RA. The results showed that moxibustion significantly reduced arthritis severity scores, paw swelling, and tissue damage in the animals studied. It also decreased levels of inflammatory chemicals like IL-1β, IL-6, and TNF-α that drive joint inflammation and damage. Additionally, moxibustion appeared to suppress key inflammatory signaling pathways including NF-κB and NLRP3, which are important in RA disease progression. These findings suggest moxibustion may work by modulating the body's inflammatory response and blocking molecular pathways that contribute to arthritis. While these animal study results are promising and provide scientific rationale for how moxibustion might help RA patients, it's important to note this research was conducted in laboratory animals, not humans. More clinical trials in people with RA are needed to confirm these benefits and establish optimal treatment protocols. For patients with rheumatoid arthritis considering moxibustion as a complementary therapy, these preclinical findings suggest potential benefit, though human studies are still needed. If you're interested in trying moxibustion for arthritis, seek care from a licensed acupuncturist or traditional Chinese medicine practitioner with appropriate training and credentials.
This PROSPERO-registered systematic review and meta-analysis evaluated moxibustion efficacy in rheumatoid arthritis animal models across 73 randomized controlled studies. Primary outcomes demonstrated significant reductions in arthritis severity: arthritis index (SMD -3.72, 95% CI -4.25 to -3.20), paw volume (SMD -4.59, 95% CI -5.54 to -3.63), and histopathological scores (SMD -2.24, 95% CI -2.80 to -1.67). Secondary outcomes showed substantial suppression of pro-inflammatory cytokines including IL-1β (SMD -3.52, 95% CI -4.19 to -2.86), IL-6 (SMD -3.17), and TNF-α (SMD -3.38), alongside downregulation of key inflammatory signaling pathways: NF-κB (SMD -2.29), NLRP3 inflammasome (SMD -1.74), TLR4 (SMD -6.72), and MyD88 (SMD -9.16). The large effect sizes across multiple inflammatory markers suggest moxibustion's anti-arthritic effects operate through multi-targeted immunomodulation, particularly via NF-κB and NLRP3 pathway inhibition. These preclinical findings provide mechanistic rationale supporting clinical investigation of moxibustion as adjunct RA therapy, though translation to human efficacy requires rigorous clinical trials.

📌 Three transdermal moxibustion compounds—Citral, α-Terpineol, and Borneol—were identified as targeting TNF-α to reduce rheumatoid arthritis through MAPK pathway inhibition and MMP modulation.
📌 Moxibustion as adjunct therapy may improve CD4+ counts and reduce antiretroviral therapy gastrointestinal side effects in HIV/AIDS patients, though evidence quality remains low.
