Antidote

Antidotes are a type of medicine that act as a cure from various poisons. They can be administered to an infected person by either drinking it or by being injected with it. Medical herbs are gathered up and combined in order to create an antidote. Also, not any old medical herbs can be used on the different types of poisons as they could increase the poison's strength or add an additional boost to it making it even deadlier. Some poisons are really complex and require careful attention or else the victim will die. However, specially trained, genius medical ninjas like Tsunade or Sakura Haruno can actually analyse and decipher the many different elements used in complex poisons and create a cure.

Types
There are different types of antidotes.
 * Antidotes are able to take liquid form and can thus be drank by people.
 * Members of the Aburame clan are able to use their kikaichū insects to enter the body of a poisoned victim where upon they will remove and neutralize the poison from an ally's body thus curing them.
 * The poison of the nano-sized, venomous insects that are used by Torune and Shikuro Aburame also has an antidote, but only Shikuro Aburame knows how to make the antidote.
 * During battle it is hard to treat a poisoned ally, for situations like these medical nijas can make the antidotes into capsules or shots and inject the injured victim with it.
 * Their are also types of antidotes used to cure colds and illnesses that can also be administered as shots.

Combating Poisons
Certain characters have encountered poisons throughout their careers as ninja. During the Second Shinobi World War, Tsunade, was able to produce antidotes to every one of Chiyo's poisons, much to the latter's resentment. During the mission to rescue Gaara, Sakura Haruno demonstrated the skill to not only extract and analyse Sasori's poison swiftly, but also produced an antidote to counter it.

Apart from using antidotes to poisons, a ninja can also work to build-up a tolerance to certain poisons by gradually exposing oneself to non-lethal amounts of those poisons. Orochimaru, in the effort to make Sasuke Uchiha into the perfect vessel for his Living Corpse Reincarnation technique, made it a point to make Sasuke immune to most poisons, such as the one that Shizune taught to Sakura Haruno in order to use on her kunai.
