Botanical Name : Datura stramonium
Family: Solanaceae
Genus: Datura
Species: D. stramonium
Kingdom: Plantae
Order: Solanales

Common Names:Jimson weed or datura

Habitat : Original habitat is obscure,but is believed to have originated in the Americas, it is found in many areas of the world, occasionally in S. Britain.Grows in  dry waste ground and amongst rubble or the ruins of old buildings.

(The native range of Datura stramonium is unclear. It was scientifically described and named by Swedish botanist Carl Linnaeus in 1753, although it was earlier described by many herbalists, such as Nicholas Culpeper. Today, it grows wild in all the world’s warm and moderate regions, where it is found along roadsides and in dung heaps. In Europe, it is found as a weed on wastelands and in garbage dumps.

The seed is thought to be carried by birds and spread in their droppings. It can lie dormant underground for years and germinate when the soil is disturbed. People who discover it growing in their gardens, and are worried about its toxicity, have been advised to dig it up or have it otherwise removed)

Description:
Datura stramonium is a foul-smelling, erect annual, freely-branching herb that forms a bush up to 2–5 ft (1–1.5 m) tall.

The root is long, thick, fibrous and white. The stem is stout, erect, leafy, smooth, and pale yellow-green. The stem forks off repeatedly into branches, and at each fork forms a leaf and a single, erect flower.

The leaves are approximately 3-8 inches long, smooth, toothed, soft, irregularly undulate. The upper surface of the leaves is a darker green, and the bottom is a light green. The leaves have a bitter and nauseating taste, which is imparted to extracts of the herb, and remains even after the leaves have been dried.

Datura stramonium generally flowers throughout the summer. The fragrant flowers are trumpet-shaped, white to creamy or violet, and 2.5 to 3.5 in. long, and grow on short stems from either the axils of the leaves or the places where the branches fork. The calyx is long and tubular, swollen at the bottom, and sharply angled, surmounted by 5 sharp teeth. The corolla, which is folded and only partially open, is white, funnel-shaped, and has six prominent ribs. The flowers open at night, emitting a pleasant fragrance and providing food for nocturnal moths.

The egg-shaped seed capsule is walnut-sized and either covered with spines or bald. At maturity it splits into four chambers, each with dozens of small black seeds.

It is hardy to zone 7 and is not frost tender.

Cultivation: 
Succeeds in most moderately good soils but prefers a rich light sandy soil or a calcareous loam, and an open sunny position. Plants often self-sow when well sited. The thornapple is cultivated commercially as a medicinal plant. It can become a weed in suitable conditions and is subject to statutory control in some countries. This species is extremely susceptible to the various viruses that afflict the potato family (Solanaceae), it can act as a centre of infection so should not be grown near potatoes or tomatoes. Grows well with pumpkins. The whole plant gives off a nauseating stench.

Propagation: 
Sow the seed in individual pots in early spring in a greenhouse. Put 3 or 4 seeds in each pot and thin if necessary to the best plant. The seed usually germinates in 3 – 6 weeks at 15°c. Plant out in late spring or early summer, after the last expected frosts. Especially in areas with hot summers, it is worthwhile trying a sowing outdoors in situ in mid to late spring…..click & see

The thornapple is a bitter narcotic plant that relieves pain and encourages healing. It has a long history of use as a herbal medicine, though it is very poisonous and should be used with extreme caution. The leaves, flowering tops and seeds are anodyne, antiasthmatic, antispasmodic, hallucinogenic, hypnotic, mydriatic and narcotic. The seeds are the most active medicinally. The plant is used internally in the treatment of asthma and Parkinson’s disease, excess causes giddiness, dry mouth, hallucinations and coma. Externally, it is used as a poultice or wash in the treatment of fistulas, abscesses wounds and severe neuralgia. The use of this plant is subject to legal restrictions in some countries. It should be used with extreme caution and only under the supervision of a qualified practitioner since all parts of the plant are very poisonous and the difference between a medicinal dose and a toxic dose is very small. The leaves should be harvested when the plant is in full flower, they are then dried for later use. The leaves can be used as a very powerful mind-altering drug, they contain hyoscyamine and atropine. There are also traces of scopolamine, a potent cholinergic-blocking hallucinogen, which has been used to calm schizoid patients. Atropine dilates the pupils and is used in eye surgery. The leaves have been smoked as an antispasmodic in the treatment for asthma, though this practice is extremely dangerous. The seeds are used in Tibetan medicine, they are said to have a bitter and acrid taste with a cooling and very poisonous potency. Analgesic, anthelmintic and anti-inflammatory, they are used in the treatment of stomach and intestinal pain due to worm infestation, toothache and fever from inflammations.

It is anti-asthmatic, antispasmodic, good for swellings and healing wounds  Traditional medicinal uses include placing a folded leaf behind the ear to allay motion-sickness, or applying a fresh leaf poultice externally to allay the pain of rheumatic or glandular swellings. Leaves and seeds were once smoked with Mullein for treating asthma.

Spiritual Uses:
For centuries, Datura stramonium has been used as a mystical sacrament which brings about powerful visions (lasting for days) and opens the user to communication with spirit world.

The ancient inhabitants of what is today central and southern California used to ingest the small black seeds of datura to “commune with deities through visions”. Across the Americas, other indigenous peoples such as the Algonquin, Cherokee, Marie Galente and Luiseño also utilized this plant in sacred ceremonies for its hallucinogenic properties. In Ethiopia, some students and debtrawoch (lay priests), use D. stramonium to “open the mind” to be more receptive to learning, and creative and imaginative thinking.

The common name “datura” has its roots in ancient India, where the plant was considered particularly sacred — believed to be a favorite of the Hindu god Shiva Nataraja

Known Hazards: All parts of Datura plants contain dangerous levels of the tropane alkaloids atropine, hyoscyamine and scopolamine which are classified as deliriants, or anticholinergics. There is a high risk of fatal overdose amongst uninformed users, and many hospitalizations occur amongst recreational users who ingest the plant for its psychoactive effects.

The amount of toxins varies widely from plant to plant. There can be as much as a 5:1 variation across plants, and a given plant’s toxicity depends on its age, where it is growing, and the local weather conditions. Additionally, within a given datura plant, concentrations of toxins are higher in certain parts of the plant than others, and can vary from leaf to leaf. When the plant is younger, the ratio of scopolamine to atropine is approximately 3:1; after flowering, this ratio is reversed, with the amount of scopolamine continuing to decrease as the plant gets older.  This variation makes Datura exceptionally hazardous as a drug. In traditional cultures, a great deal of experience with and detailed knowledge of Datura was critical in order to minimize harm. An individual datura seed contains about 0.1 mg of atropine, and the approximate fatal dose for adult humans is >10mg atropine or >2-4mg scopolamine.

Datura intoxication typically produces delirium (as contrasted to hallucination); hyperthermia; tachycardia; bizarre behavior; and severe mydriasis with resultant painful photophobia that can last several days. Pronounced amnesia is another commonly reported effect. The onset of symptoms generally occurs approximately 30 minutes to an hour after smoking the herb. These symptoms generally last from 24 to 48 hours, but have been reported in some cases to last as long as 2 weeks.

As with other cases of anticholinergic poisoning, intravenous physostigmine can be administered in severe cases as an antidote
