This work evaluated the local anaesthetic activity of milky latex obtained from Calotropis gigantea using three different experimental models in frog and Guinea pig. The latex at dilution 1:10 showed the anaesthetic activity compared to the standard drug xylocaine (0.2%). The methods used are nerve block or lumbar plexus anaesthesia and muscle twitch in frog, infiltration anaesthesia in Guinea pig. It was concluded that latex of Calotropis gigantea (1:10 dilution ) exhibited significant local anaesthetic activity.
