Background: An impaired fibrinolytic function had been reported in subjects suffering from venous thrombosis. The euglobulin clot lysis time is a test that reflects the overall fibrinolytic activity of plasma. Objective: To evaluate the fibrinolytic efficacy of ethanolic extract of Averrhoa bilimbi Linn. leaves by using Euglobulin lysis time method. Methods: Rats were divided into 3 groups. Each group was containing 6 rats. Group I: received vehicle (control) 0.9% saline solution; Group II: received 25 mg/kg ethanolic extract leaves of Averrhoa bilimbi Linn; Group III: received 50 mg/kg ethanolic extract leaves of Averrhoa bilimbi Linn. Blood (1.8 ml) was removed with a plastic syringe containing 0.2 ml 3.8% sodium citrate solution. The time interval between the addition of thrombin and the complete lysis of the clots was measured. The lysis time (min) was determined. Conclusion: We observed ethanolic extract of Averrhoa bilimbi Linn. leaves may increase the activators of the fibrinolysis. Further investigation is warranted.
