RESUMO
The scientific basis of moxibustion using moxa was investigated, focusing on the characteristics and thermal stimulation properties of moxa, its biochemical characteristics and actions, and morphological changes in skin tissue treated with moxibustion. The presentations by and viewpoints of the symposists are outlined below:<BR>1) Characteristics and thermal stimulation properties of moxa:The thermal stimulation properties of Artemisia princes Pamp., moxa, materials other than Artemisia princes Pamp., and materials similar to moxa were presented. Re-investigation of the results of common views of Artemisia princes Pamp. and moxa by experiments and a survey were also presented. <BR>2) Biochemical characteristics and actions of moxa:Chemical substances contained in Artemisia princes Pamp. and moxa, and diverse physiological actions of moxa, such as an anti-oxidative stress action, signal transduction, activation of energy metabolism, and anti-inflammatory action, were presented with viewpoints. In addition, biochemical actions were reviewed based on the extraction of new chemical components. <BR>3) Morphological changes in skin tissue treated with moxibustion:Moxibustion-induced morphological changes in the epidermis, connective tissue, blood vessels, and nerve tissue were presented. Regarding skin tissue regeneration, viewpoints were presented, emphasizing that actions of corneocytes and fibroblasts are particularly important, in addition to revascularization, nerve fibers are not regenerated unless the skin tissue is repaired to a certain degree.
