Abstract
From studies on the reactivity of Chinese traditional (Kampo) medicines, Rikko-san, Daio-kanzo-to, their six herbal constituents, and other substances with human whole saliva, we discussed here a possibility that the human whole saliva plays an important role in both medical effects and oral hygiene. The polyphenol contents of those were measured and the polyphenol's capabilities of complex formation with either saliva or gelatin were determined. Furthermore, their inhibitory effects on in vitro formation of calcium phosphate precipitates together with synergistic effects on it and chelating ability were investigated. From these data, it was concluded that the reactivity of polyphenols of Chinese traditional (Kampo) medicines with human whole saliva might be associated with medical effects and oral hygiene, e.g. anti-calculus formation.
