Anodyne Anthelmintic Antiasthmatic Antidandruff Antiinflammatory Antispasmodic Hallucinogenic Hypnotic
Mydriatic Narcotic
The thornapple is a bitter narcotic plant that relieves pain and encourages healing[238]. 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[1, 4, 7, 9, 13, 21, 46, 165, 238, 240]. The seeds are the most active medicinally[4]. The plant is used internally in the treatment of asthma and Parkinson's disease, excess causes giddiness, dry mouth, hallucinations and coma[238]. Externally, it is used as a poultice or wash in the treatment of fistulas, abscesses wounds and severe neuralgia[238, 257]. The use of this plant is subject to legal restrictions in some countries[238]. 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[21, 213, 238]. The leaves should be harvested when the plant is in full flower, they are then dried for later use[4]. The leaves can be used as a very powerful mind-altering drug, they contain hyoscyamine and atropine[213]. There are also traces of scopolamine, a potent cholinergic-blocking hallucinogen, which has been used to calm schizoid patients[213]. Atropine dilates the pupils and is used in eye surgery[222]. The leaves have been smoked as an antispasmodic in the treatment for asthma, though this practice is extremely dangerous[213, 222]. The seeds are used in Tibetan medicine, they are said to have a bitter and acrid taste with a cooling and very poisonous potency[241]. 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[241]. The juice of the fruit is applied to the scalp to treat dandruff[243].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses
Hair Repellent
The growing plant is said to protect neighbouring plants from insects[18, 20]. The juice of the fruits is applied to the scalp to cure dandruff and falling hair[243]. There has also been considerable interest in the use of extracts of Datura species as botanical pesticides. D. metel, for example, appears to suppress a number of nematode species of economic importance. Landscape Uses: Border, Container, Foundation, Specimen.

Cultivation details
Landscape Uses: Border, Container, Foundation, Specimen. Succeeds in most moderately good soils but prefers a rich light sandy soil or a calcareous loam, and an open sunny position[1, 4, 200]. Plants often self-sow when well sited[1]. The thornapple is cultivated commercially as a medicinal plant[57]. It can become a weed in suitable conditions and is subject to statutory control in some countries[238]. 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[200]. Grows well with pumpkins[20]. The whole plant gives off a nauseating stench[245]. Special Features:
North American native, Naturalizing, All or parts of this plant are poisonous, Fragrant flowers, Attractive flowers or blooms.

Propagation
Sow the seed in individual pots in early spring in a greenhouse[200]. 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.
