Graphical Abstract:


Background: Carissa spinarum Linn has been used as a traditional medicine to treat various ailments, including snakebite. It is found in India, Ceylon and Thailand.

Objective: The study was performed to determine the inhibiting potential of Carissa spinarum methanolic leaf extract on the pharmacological effects of Viper venom.

Methods: The dose-dependent enzymatic studies, pharmacological and in vivo studies were conducted using standard methods.

Results: It neutralized toxic enzymes in a dose-dependent manner with concentrations ranging from 53.3 –1190.4 μg/mL, inhibited lysis of fibrinogen at 1:8 (venom: extract, w/w), and increased the procoagulant activity and lecithin lysis at 1:25 (venom: extract, w/w). The extract neutralized the LD50 of venom in mice and embryos, reduced haemorrhage, myotoxicity and edema induced by the venom in mice.

Conclusion: The observed results confirm that the leaf extract possesses adequate phytochemicals that could neutralize the toxic properties of the venom.

Keywords: In vivo, snake bite, haemorrhage, Vipera russelli, fibrinogenolysis, Carissa spinarum Linn.
