Kodoku

Kodoku

Kodoku (蠱毒) (worm toxin) is a type of poisonous magic found in Japanese folklore. It is the Japanese derivative of the Chinese Gu (poison) magic. To create kudoku, sorcerers would mix several insects in a jar, and let them kill one another until only one survived. The fluids of the insect that survived would be used to poison an individual with a curse that would control them, cause them misfortune, or kill them. The term "kodoku" can also be applied to the spirit which is the incarnation of this particular magic. The technique was used in the Nara Period.
