The venom consists mainly of both pre-synaptic and post-synaptic neurotoxins, cardiotoxins, and fasciculins. The toxicity of the venom can vary tremendously depending on various factors including diet, geographical location, age-dependent change, and other factors. The SC and IV for this species is 0.79 mg/kg and 0.71 mg/kg, respectively (Christensen and Anderson (1967)). One study determined the LD50 of the venom administered to mice via the intraperitoneal (IP) route was 0.33 mg/kg. In another test using mice that were administered the western green mamba's venom via the intraperitoneal (IP) route the LD50 was 0.045 mg/kg. Another experimental IV LD50 toxicity of 0.5 mg/kg has been reported, with an average wet venom yield of 100 mg. Like other mamba species, western green mamba venom is among the most rapid-acting venom of snakes.
