对传统艾灸、替代物灸和人体穴位红外辐射光谱的分析比较发现,隔附子饼灸、隔姜灸和隔蒜灸三种传统间接灸与人体穴位归一化红外辐射光谱有惊人的一致性,其辐射峰均在7.5μm附近;而几种替代物灸与相应传统艾灸和人体穴位的辐射光谱相差甚远,其温热作用也远不如传统艾灸;传统艾条薰灸与人体穴位红外辐射光谱也有很大差异. 结果提示,在传统间接灸的治疗效应中,间接灸和穴位的红外共振辐射起重要作用;从艾灸的红外物理特性看,替代物灸尚不能替代传统艾灸.

By analyzing and comparing the infrared radiation spectrums of the traditional moxibustion, the substitute moxibustion and acupoints, it was found that there was a surprising consistency in the spectrums of three types of indirect moxibustion, namely separated with prepared daughter root of common monkshood, ginger and garlic, and the unified spectrum of acupoints of human body. Both had their peaks of radiation near 7.5μm. However, the spectrum of the substitute moxibustion was completely different from them. Its warming function was far less than the traditional moxibustion. And there was also a big difference between the infrared radiation spectrums of the moxa stick smoking and acupoints. The result indicates that in the therapeutic effect of traditional indirect moxibustion the sympathetic vibration of infrared radiation of indirect moxibustion and acupoints play an important role and the substitute moxibustion could not replace the traditional moxibustion in terms of the infrared characteristics of moxibustion.
