Tannins: In regard to the antidiar-rheal and anti-inflammatory properties mentioned above, one might set the hypothesis that condensed tannins such as cinnamtannin B1, proantho-cyanidins A1 and epicatechin-(4p ^

7)-catechin which display strong anti-oxidant properties experimentally (Ho KY et al., 1999) are involved. Epicatechin-(4 p ^ 8)-epicatechin-(4p ^ 8, 2p ^ O ^ 7)-catechin inhibits the proliferation of the periodontal pathogen Porphyromonas gingivalis and Porphyromonas intermedia cultured in vitro (Ho KH etal., 2001). Such tannins are notably present in tea. A water extract of Vaccinium vitis-idaea L. inhibits platelet activating factor-induced exocytose in vitro, thereby confirming the anti-inflammatory property (Tunon H et al., 1995).
