that's called milking the snake
"Snake Milk" is a term which refers to the droplets of venom one obtains by "milking" a snake. It is often used for scientific study and the making of anti-venom.
Milking a snake is the term used for getting venom out of a living snake. It is done by hooking the snake's fangs over the edge of a glass as if it was biting something and pressing on the venom glands. The venom is then used to create anti-venoms and in medical research.
Albert Calmette first invented antivenin in the 1890s. Calmette sought to cure cobra bites in Vietnam by milking the snakes and injecting the venom into horses to stimulate antibody production.
Venom can lift 40 tons
A bite from a coral snake injecting 3-5mg of venom, is usually fatal. Compare that to the Mojave rattle snake which would have to inject three times that amount. The actual yield from 'milking' a Coral snake would be higher - and would depend on the size of the venom glands in each individual snake.
The answer is venom its the same with spiders too.
The milking machine in 1930 according to my research costes $2.45, in that time that was quite a bit of money.

When a person is bitten by a venomous snake the venom is processed as an antidote. Milking venomous snakes of all species is a big business and it is surprising how many people do this as a profession.
