The protein makeup differs between the three species of stonefish, but in reef stonefish the fatal protein is the verrucotoxin protein. [15] Effects of the venom include severe pain, shock, paralysis, and tissue ...
The plants' teratogenic properties and ability to induce severe birth defects were well known to Native Americans, [148] although they also used minute amounts of the winter-harvested root (combined with Salvia dorii to potentiate its effects and reduce the toxicity of the herb) to treat cancerous tumors.

[2] The LD 50 of L. geometricus venom has been measured in mice as 0.43 mg/kg, [11] and separately again as 0.43 mg/kg (with a 95% confidence ...
These side effects may last up to 72 hours after injection of the venom. It is also observed that penile erection may occur after being stung. The pain of a sting from the Arizona Bark Scorpion has been compared to being struck by a bolt of lightning or electrical current. [ 5 ]

Similar to those of other recluse spiders, their bites sometimes require medical attention. The brown recluse is one of three spiders in North America with dangerous venom, the others being the black widow and the Chilean recluse.
