Datura metel
The common name "datura" has its origins in India, where the sister species "Datura metel" is considered particularly sacred — believed to be a favorite of Shiva in Shaivism. Both "Datura stramonium" and "D. metel" have reportedly been used by some sadhus and charnel ground ascetics, such as the Aghori as both an entheogen and ordeal poison. It was sometimes mixed with cannabis as well as highly poisonous plants like "Aconitum ferox" to intentionally create dysphoric experiences. They used unpleasant or toxic plants such as these in order to achieve spiritual liberation ("moksha") in settings of extreme horror and discomfort.
