The plant today

Datura metel is a shrub-like annual (zone 5–7) or short-lived, shrubby perennial (zone 8–10), commonly known in Europe as Indian thornapple, Hindu datura, or metel and in the United States as devil's trumpet or angel's trumpet. Datura metel is naturalised in all the warmer countries of the world. It is found notably in India, where it is known by the ancient, Sanskrit-derived, Hindi name dhatūra (धतूरा), from which the genus name Datura is derived. The plant is cultivated worldwide, both as an ornamental and for its medicinal properties, the latter being due to its tropane alkaloid content.

Uses

The applications of this species are identical with those of D. Stramonium and it is official in the Pharmacopœia of India. It is antispasmodic, narcotic and toxic, and is used quite commonly with criminal intent in India and Indo-China. The cooked and bruised leaves make an efficient poultice in articular rheumatism.

The symptoms of poisoning by “dhatura” are: dilatation of the pupil, general malaise, dryness of the fauces and skin, hallucinations, rapid pulse, coma and death or permanent mania.

The dry leaf is smoked to abort asthma, and though its action is uncertain, it is one of the many remedies that should be tried, which though ineffective in one case may in another afford positive relief in this distressing disease. Not more than 1.50 grams should be smoked in one day and their use should be discontinued if any symptom of intoxication supervenes. The Pharmacopœia of India contains a tincture made from 75 grams of the ground seeds and 500 grams of alcohol. Dr. Waring states that 20 drops of this tincture are equivalent to 6 centigrams of opium and that in some cases it has given him better narcotic results than the opium. The extract is made from 500 grams of the powdered seeds, 500 cc. ether, 500 cc. alcohol and 500 cc. water. Dose, 5–20 centigrams a day in 4 doses.

The D. fastuosa, L., known in Manila by the common name of Talamponay na itim, Tag., possesses the same properties as the above. The Filipino physician, Sr. Zamora, successfully employed a poultice of bruised leaves cooked in vinegar and applied to the forehead and backs of the hands to reduce the fever of tuberculous patients.

Neither the leaves nor seeds of these two varieties of Datura have been studied from a chemical standpoint, but there is little doubt that the active principle is the daturine (atropine and hyoscyamine) that exists so abundantly in D. Stramonium.

Botanical description

Plant 5–6° high, with nodose branches, forked. Leaves ovate, angled, somewhat downy. Flowers large, white, axillary, solitary. Calyx tubular, 5-toothed. Corolla funnel-shaped, the limb 5-angled and 5-folded. Stamens 5, same length as calyx. Anthers long, flattened. Stigma thick, oblong, divisible in 2 leaves. Seed vessel globose, thorny, 4-valved over the base of the calyx. Seeds numerous, flattened, kidney-shaped.
