In book IIII.75: "The root has a property that causes not unpleasant fantasies when a quantity of one drachma is drunk with wine, but when a quantity of two drachmai is drunk, it drives a person out of his senses for up to three days; and if a quantity of four drachmai is drunk, it kills; drinking and vomiting large quantities of hydromel is its antidote."

For example, the Tantra states "[M]aking an image of the enemy with the excrement and urine of those who follow the great Dharma, wrathfully burn it in a fire of thorn-wood, and even the Buddha will certainly perish. [...] So he said black mustard-seeds, salt, oil, poison, and thorn-apple [datura], these are taught as the supreme destroyers of all the Buddhas."
