Datura is a genus of 12-15 species of vespertine flowering plants belonging to the family Solanaceae. Their exact natural distribution is uncertain, due to extensive cultivation and naturalization throughout the temperate and tropical regions of the globe, but is most likely restricted to the Americas, from the United States south through Mexico (where the highest species diversity occurs) to the mid-latitudes of South America. Some species are reported by some authorities to be native to China, but this is not accepted by the Flora of China, where the three species present are treated as introductions from the Americas. It also grows naturally throughout India and most of Australia. According to the old ayurvedic medicinal system (at least since 2000 BC) in India, this plant has versatile uses in medicinal preparations.

Description

Datura is a woody-stalked, leafy herb growing up to 2 meters. It produces spiney seed pods and large white or purple trumpet-shaped flowers that face upward. Most parts of the plant contain atropine, scopolamine, and hyoscyamine. It has a long history of use both in S. America and Europe and is known for causing delirious states and poisonings in uninformed users. Common names include jimson weed, Hell's Bells, Devil's weed, Devil's cucumber, thorn-apple (from the spiny fruit), pricklyburr (similarly), and somewhat paradoxically, both angel's trumpet and devil's trumpet,(from their large trumpet-shaped flowers), or as Nathaniel Hawthorne refers to it in the the Scarlet Letter apple-Peru. The word Datura comes from Hindi dhatūrā (thorn apple); record of this name dates back only to 1662 (OED). The Hindi derives this word from Sanskrit vedic literature that dates to long before 2000 BC^{[citation needed]}.

They are large, vigorous annual plants or short-lived perennial plants, growing to 1-3 m tall. The leaves are alternate, 10-20 cm long and 5-18 cm broad, with a lobed or toothed margin. The flowers are erect or spreading (not pendulous), trumpet-shaped, 5-20 cm long and 4-12 cm broad at the mouth; color varies from white to yellow, pink, and pale purple. The fruit is a spiny capsule 4-10 cm long and 2-6 cm broad, splitting open when ripe to release the numerous seeds.

Datura species are used as food plants by the larvae of some Lepidoptera species including Hypercompe indecisa.

Cultivation and uses

Datura contains the alkaloids scopolamine and atropine and has been used in some cultures as a poison and hallucinogen.^[1]

The dose-response curve for the combination of alkaloids is very^{[citation needed]} steep, so people who consume datura can easily take a potentially fatal overdose, hence its use as a poison. In the 1990s and 2000s, the United States media contained stories of adolescents and young adults dying or becoming seriously ill from intentionally ingesting datura.^[2]

Records of use

Datura stramonium is also called jimsonweed. This name comes from the town of Jamestown, Virginia. Various versions of the story exist, but in the most common version, British soldiers sent to quell Bacon's Rebellion of 1676 were accidentally served this unfamiliar plant as food, causing many to be incapacitated for 11 days. Datura wrightii, also called sacred datura or western jimsonweed, has similar effects.

Chaitanya Charitamrita, a 16th century biography of the saint Caitanya who was known for his fervent religious ecstasies, describes an incident (2.18.165, 183) where Muslim soldiers, unable to comprehend his state of trance, apprehend four of his companions on suspicion of their poisoning him with dhuturā with an aim to loot his possessions. Upon regaining consciousness, Caitanya attributes his trance episode to epilepsy.

Effects of ingestion

Due to the potent combination of anticholinergic substances it contains, Datura intoxication typically produces effects similar to that of an anticholinergic delirium: a complete inability to differentiate reality from fantasy (frank delirium, as contrasted to hallucination), hyperthermia, tachycardia, bizarre, inexplicable and possibly violent behavior, and severe mydriasis with resultant painful photophobia that renders the subject nearly blind for several days.

According to the drug information site Erowid, no other substance has received as many "Train Wreck" severely-negative experience reports as has Datura^[3], noting that "the overwhelming majority of those who describe to us their use of Datura (and to a lesser extent, Belladonna, Brugmansia and Brunfelsia) find their experiences extremely mentally and physically unpleasant and not infrequently physically dangerous."

The full listing of reports can be found at www.erowid.org. Numerous stories of datura-related deaths and critical illnesses can also be found at the Lycaeum Datura index here.
