RegelDatura wrightii or Sacred Datura is the name of a poisonous perennial plant and ornamental flower of southwestern North America. It is sometimes used as a hallucinogen. Datura wrightii is classified as a deliriant and an anticholinergic.[1]
It is a vigorous herbaceous perennial[2] that grows 30 cm to 1.5 m tall and wide.[3] The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 cm (8 inches) long, often tinted purple, especially at the margin. There are five narrow points spaced symmetrically around the rim. It can bloom from April to October.[2] In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; in cloudy weather, they may open earlier and last longer.
The seeds are borne in a spiny, globular capsule 3 to 4 cm in diameter, which opens when fully ripe.[2]
Datura wrightii is found in northern Mexico and the adjoining U. S. states, as far north as southern Utah, in open land with well-drained soils.[2] It is also commonly planted as an ornamental, especially in xeriscapes.
The name commemorates the botanist Charles Wright.

Other names
Seed pods
In the U.S. it is sometimes called (Western) Jimsonweed[3] because of its resemblance to Datura stramonium. Anglophone settlers in California often called it "Indian whiskey" because of its ritual intoxicating use by many tribes; the name "sacred datura" has the same origin. Other common names include "Indian apple"[2] and "nightshade" (not to be confused with Solanum). The Tongva call it manit and the Chumash momoy. Mexicans call this and similar species tolguacha[2] or toloache.[4]
The scientific name has frequently been given as Datura meteloides Dunal,[3] but this name is actually a synonym of D. inoxia Mill., a Mexican plant with a narrower flower having 10 rather than 5 "teeth" at the rim.[2]
Toxicity

Uses
Religious
Datura wrightii is sacred to some native Americans and has been used in ceremonies and rites of passage by Chumash, Tongva, and others. Among the Chumash, when a boy was 8 years old, his mother gave him a preparation of momoy to drink. This was supposed to be a spiritual challenge to the boy to help him develop the spiritual wellbeing that is required to become a man. Not all of the boys survived.[1] They believed momoy was a spiritual plant that helps with spiritual wellbeing among adults also. For instance, during a frightening situation, such as when seeing a coyote walk like a man, a leaf of momoy was sucked to help keep the soul in the body. The plant was also used to tell the future, especially when gambling.
Recreational
Datura wrightii has also been used to induce hallucination for recreational purposes. Ingestion of plant material can induce auditory and visual hallucinations similar to those of Datura stramonium, with the active compounds being concentrated in the seedpods and roots; concentrations vary widely between samples, and onset is slow. This makes dosage estimation a difficult and adds further risk to the administration of material that already has potentially lethal side effects. Scopolamine is the primary active molecule; it is related to atropine, with a similar, largely anticholinergic activity. Effects may include dry mouth, hyperthermia, profuse sweating, drowsiness, lethargy and anteriograde amnesia - along with the before-mentioned hallucinations and sensory distortions. These compounds also induce a profound dilatation of the pupils and suppress eye saccades, resulting in considerable degradation of visual acuity, often to the point of functional blindness. This may persist, to a reduced degree, for days. The combined effect may result a panic state in the user, a particularly dangerous situation in someone temporarily deprived of useful vision; users are prone to serious accidental injury. Scopolamine induces respiratory depression at hallucinogenic doses. The combination of anesthesia (in the hospital) and Datura is usually fatal due to combined respiratory depression.[1] Seizures and fevers as high as 43 C (110°F) have been reported.
