The haemolytic effect of crude methanolic plant extracts on sheep erythrocytes. The erythrocyte suspension was incubated with an equal volume of test samples dissolved in PBS at a concentration range of 32 to 250 μg/mL at 37℃. Methanolic plant extracts had greater haemolytic activity at higher concentrations. F. indica and V. verrucosum methanolic extracts caused haemolysis at the highest concentration of 250 μg/mL, with V. verrucosum also exhibiting haemolytic activity at 125 μg/mL
