In healthy volunteers orally administered ginkgo capsules at the manufacturer s recommended dose (amount not specified) daily for two weeks, no effects on platelet function or other hematological parameters were observed, including prothrombin time, partial thromboplastin time, thrombin time, bleeding time, the collagen/epineph-rine assay, or the collagen/adenosine diphosphate assay. Aspirin (325 mg daily) was used as a positive control and markedly inhibited platelet function (Beckert et al. 2007).
