Background: Various herbal side effects caused by interactions between herbs and drugs have been reported and reviewed. For instance, roselle water extract and aspirin have similar functions in maintaining cardiovascular function. Objective: This study aimed to investigate the effect of roselle water extract on aspirin pharmacodynamics observed through the parameters of bleeding time, survival rate and the number of microthrombus that induced thromboembolism in rats. Materials and Methods: Male Sprague-Dawley rats were divided into two different experimental group for bleeding time and survival rate assay. Roselle water extract was given in three various doses (12.5 mg, 25 mg, 50 mg/200 g BW) for seven days followed by aspirin on the last treatment. Results: Results showed that the co-administration of roselle water extract and aspirin did not cause significant changes in the increase in bleeding time, the number of animals that survived and the number of microthrombus. Conclusion: Therefore, roselle water extract does not affect the pharmacodynamics of aspirin.

Background: Previous studies on virtual screening on P2Y12 receptor of Adenosine Diphosphate (ADP) have showed that Roxburghine B, the compound which is found in Uncaria species, can inhibit the receptor function. Objective: In this study, we investigated the effect of Uncaria gambir and Uncaria sclerophylla extract on survival rate and bleeding time as antithrombotic in vivo. Methods: Animal subjects (ddY strain mice) were divided to two different experimental group (survival rate and bleeding time). U. gambir and U. sclerophylla were given to the mice orally in three different dose (5 mg, 10 mg, 20 mg/20 g BW and 2.5 mg, 5 mg, 10 mg/20 g BW, respectively) for seven days. Results: U. gambir and U. sclerophylla able to prolong bleeding time from test subjects equivalent to ASA as standard. The results show the increasing number of survived animals in the treated group compared to the negative control group. Conclussion: Both of U. gambir and U. sclerophylla prevent pulmonary thromboembolism on mice subjects represent by the increased of survival rate. Antithrombotic effects that were observed suggested was provide by their antiplatelet activity.

Background: Mucuna pruriens (MP) L. and Coriandrum sativum (CS) have been found for in vitro antithrombotic activity. However, the in vivo studies for both plants have not been discovered yet. Objective: The objective of the study is to prove the efficacy of MP L. and CS by conducting in vivo antithrombotic activity test with bleeding time and survival rate as the parameters. Materials and Methods: MP and CS extracts with three different doses were given orally to the experimental animals for 7 days. Aspirin was used as a positive control. The bleeding time was observed on mice tail that had been cut, and the survival rate was determined by inducing thrombosis with collagen{\textendash}epinephrine injection. Results: Seven-day treatment of plant extracts significantly prolonged the bleeding time of the treated group compared to the normal control group. The result demonstrated the increasing number of survived animals in the treated group compared to the negative control group. Conclusion: Both extracts had shown antithrombotic activity by significantly prolonged the bleeding time and increased the survival rate.

Objective: Kaempferia galanga L. and Curcuma xanthorrhiza Roxb. have been proven to possess antiplatelet activity in vitro. The aim of this study is to investigate the antithrombotic effect of the rhizome extracts of Kaempferia galanga L. and Curcuma xanthorrhiza Roxb in a mouse thrombotic model. Methods: The ethanol extracts of K. galanga and C. xanthorrhiza were orally administered with three different doses (7, 14 and 28 mg/20 g BW) in two experimental mouse models. Bleeding time prolongation was observed on mice tail that had been cut and the survival rate of mice was observed after thromboembolism induction by collagenepinephrine. These two experiments were observed after 7 days extracts pre-treatment and compared to the positive control, aspirin. Results: A potent effect of K. galanga and C. xanthorrhiza extracts were demonstrated through significant bleeding time prolongation compared to control group. C. xanthorrhiza extract exhibited better activity than K. galanga extract. Moreover, both K. galanga and C. xanthorrhiza extracts significantly protected mice from thromboembolic death, where the protective effect of C. xanthorrhiza extract was stronger than K. galanga extract in a dose-dependent manner. Conclusion: K. galanga and C. xanthorrhiza extracts have a potential to be developed as antithrombotic agents against platelet thromboembolism.
