Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

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].
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.

Weed Potential

Right plant wrong place. We are currently updating this section. Please note that a plant may be invasive in one area but may not in your area so it’s worth checking.

D. stramonium is very widely distributed in temperate and tropical areas and is likely to be found in almost any summer crop. Indeed, Holm et al. (1997) state that it has been reported as a weed in more than 40 crops in almost 100 countries.

Within the American youth culture of today, there is a resurgence of use of this herb for recreational purposes. There are many instances of overdosage and death. It is extremely dangerous.

I have one of these plants growing in a container - it appeared in May and is quite large now. The plant I had originally put in there has gradually died as the thorn apple has thrived. It has taken me ages to find out what type of plant it is - I live in Scotland and have never seen it before. I've even been around a couple of botanic gardens to try and identify it - no wonder they didn't have any growing there!
