Thrombolytic potential of Ocimum sanctum L., Curcuma longa L., Azadirachta indica L. and Anacardium occidentale L.
Atherothrombotic diseases such as myocardial or cerebral infarction are serious consequences of the thrombus formed xin blood vessels. Thrombolytic agents are used to dissolve the already formed clots in the blood vessels; however, these drugs have certain limitations which cause serious and sometimes fatal consequences. Herbal preparations have been used since ancient times for the treatment of several diseases. The aim of this study was to investigate whether herbal preparations possess thrombolytic activity or not. An in vitro thrombolytic model was used to check the clot lysis effect of four aqueous herbal extracts viz., O. sanctum, C. longa, A. indica, A. occidentale along with Streptokinase as a positive control and water as a negative control. The percentage (%) clot lysis was statistically significant (p<0.0001) when compared with vehicle control. Using an in vitro thrombolytic model, O. sanctum, C. longa, A. indica & A. occidentale showed moderate clot lysis activity (30.01 ± 6.168%, 32.94 ± 3.663%, 27.47 ± 6.943%, 33.79 ± 2.926% respectively) whereas standard streptokinase showed 86.2 ± 10.7 % clot lysis effect. From our study we found that all the herbs showed reasonable % of clot lysis. These herbal extracts possess thrombolytic properties that could lyse blood clots in vitro; however, in vivo clot dissolving properties and active component(s) of these extracts for clot lysis are yet to be discovered.
