Datura metel Linn. (Solanaceae), D. fastuosa Linn., D. alba (Ness)
Datura stramonium, known by the common names Jimson weed or Devil's snare, is a plant in the nightshade family. It is believed to have originated in Mexico, but has now become naturalized in many other regions. Other common names for D. stramonium include thornapple and moon flower, and it has the Spanish name Toloache. Other names for the plant include hell's bells, devil’s trumpet, devil’s weed, tolguacha, Jamestown weed, stinkweed, locoweed, pricklyburr, and devil's cucumber.
For centuries, datura has been used as an herbal medicine to relieve asthma symptoms and as an analgesic during surgery or bonesetting. It is also a powerful hallucinogen and deliriant, which is used spiritually for the intense visions it produces. However, the tropane alkaloids responsible for both the medicinal and hallucinogenic properties are fatally toxic in only slightly higher amounts than the medicinal dosage, and careless use often results in hospitalizations and deaths.
