https://www.science.org.au/curious/people-medicine/using-venom-heal Was so surprised to come across this article about using modified components, or toxins, found in animal venom to help make cures. Curl my hair!!!! I had no idea. The article talks about how plantation workers who were in Brazil, would be bitten by snakes, while going about their work. The venom from the snake immediately lowered the blood pressure in the worker, who was unfortunate to be bitten, and this caused them to faint. Scientists studied this reaction and the snake venom. They were able to separate the toxins in the venom and then "tweak" what ever toxin was needed to bring about a cure, for another health issue. This modified toxin is used in medicines to control high blood pressure.
