Present Situation of Reyanbao in Pain Treatment

The Reyanbao therapy skillfully combines acupoint theory, Chinese materia medica, and thermal stimulation.It not only has the advantages of topical medication, transdermal absorption, and direct access to the disease but also avoids the influence of the first-pass effect of the liver on the efficacy of Chinese medicine.However, the current preparation craft of Reyanbao is relatively simple, and the overall research and application range are limited.It is difficult to control the effective drug dose absorbed through acupoints and meridians; The lack of researches on skin and mucosal toxicity of drugs caused limited clinical application, and large-scale studies on the standard operating procedure(SOP) of external treatment of Chinese medicine are even less.In the future, we should make full use of modern science and technology to deepen the research on the basic theories, clinical efficacy and the SOP of TCM external treatment methods, to form a relatively complete TCM technical appropriate SOP to ensure the safety, efficiency, and rationality of its clinical applications.
