Diamphotoxin increases the permeability of
cell membranes of
red blood cells. Although this does not affect the normal flow of
ions between cells, it allows all small ions to pass through cell membranes easily, which fatally disrupts the cells' ion levels.[4] Although diamphotoxin has no
neurotoxic effect, its hemolytic effect is lethal, and may reduce
hemoglobin levels by as much as 75%.[5]
The
San people of
Southern Africa use diamphotoxin as an
arrow poison for hunting
game.[1] The toxin paralyses muscles gradually. Large mammals hunted in this way die slowly from a small injection of the poison.[6]
