Given the high prevalence of atherothrombotic disease and increasing attention to functional foods, we tested the hypothesis that a combination supplement (PS) containing Phellinus baumii (PB) and Salvia miltiorrhiza Bunge (SM) may improve the atherothrombotic profile in rats. The PS (Experiment 1) or PB/SM (Experiment 2) supplement was administered orally once daily for 7 days prior to inducing platelet activation at the last day. Orally administered PS showed an additive and positive effect on nitric oxide (NO) availability, adhesion molecule/pro-inflammatory cytokine release, and thrombosis compared to controls. This effect was attributed more to PB than to SM for cyclooxygenase (COX)-1 and to SM for COX-2. In vitro data revealed that tanshinone IIA derived from SM remarkably suppressed COX-2, and protocatechuic acid derived from PB caused a small increase in NO production. The data suggest the potential use of PS to ameliorate endothelial and vascular dysfunction induced by unintended platelet activation.
