Moxibustion and it’s effectsA search in PubMed (English Database) by keywords “moxa, moxibustion” would reveal 266 articles (June 2020).
The research on moxa in the Chinese Database is significantly larger. A leading researcher published in both; English and Chinese languages is Prof. Chen Ri-Xin. He is author of 8 books and over 100 academic research papers on Moxibustion.
These studies mainly relate to the thermal, radiation and pharmacological effects of moxa and its combustion products. Experimental results show that moxibustion thermal stimulation affects both shallow and deep tissues of the skin, and the warm-heat effects of moxibustion have a close relation to the warm receptors or/and the polymodal receptor. The burning moxa radiation spectrum lies near the infrared portion of the spectrum. There is an amazing consistency in the infrared spectrums of three types of indirect moxibustion and the unified spectrum of acupoints; all have their peaks of radiation near 10 μm.
Lots of ingredients had been identified from mugwort leaves and moxa smoke, which have a variety of biological activities; they were considered to participate in the comprehensive effects of moxibustion. Therefore, there is a growing recognition of the therapeutic benefits of moxa based on contemporary research, Chinese Classics (The Yellow Emperor Canon, Materia Medica of Qing Dynasty) and empirical knowledge. However, there is a need of more research to fully understand the mechanism of moxibustion.
Moxibustion and it’s effectsIn the last decade, research papers on the therapeutic effects of moxibustion were published in the following areas:
