Antidotes

Hazard_T.svgAn antidote can be a substance which can counteract a kind of poisoning.

Occasionally, the antidote for a certain toxin is manufactured by injecting the toxin into an animal in compact doses, the resulting antibodies being extracted from the animals’ blood. The venom created by some snakes, spiders, as well as other venomous animals is typically treatable by the use of these antivenoms, although a quantity do lack one particular, and also a bite or sting from such an animal typically results in death.

Nonetheless, some toxins have no known antidote. For instance, the poison ricin, which is made from the waste byproduct of castor oil manufacture, has no antidote, and as a result is frequently fatal if it enters the human body in enough quantities.

Ingested poisons are regularly treated by the oral administration of activated charcoal, which adsorbs the poison, and after that it can be flushed from the digestive tract, removing a large part of the toxin.

Poisons which are injected into the body (including these from bites or stings from venomous animals) are often treated by the use of a constriction band which limits the flow of lymph and/or blood to the location, as a result slowing circulation from the poison about the body.
