Inhibition of the Toxic Effects of Lachesis muta, Crotalus durissus cumanensis and Micrurus mipartitus Snake Venoms by Plant Extracts

TL;DR: The ethanol extracts of eight plants utilized against snakebites by traditional healers in Colombia were examined for their possible inhibitory ability against the venoms of Lachesis muta, Crotalus durissus cumanensis, and Micrurus mipartitus to identify useful plant species for future purification of venom-neutralizing components that might become helpful in the development of supplementary therapies against snakebits.
