Dhatura

Datura stramonium is an erect, annual, freely branching herb that forms a bush up to 60 to 150 cm (2 to 5 ft) tall. The root is long, thick, fibrous, and white. The stem is stout, erect, leafy, smooth, and pale yellow-green to reddish-purple in color. The stem forks off repeatedly into branches and each fork forms a leaf and a single, erect flower.

The leaves are about 8 to 20 cm (3–8 in) long, smooth, toothed, soft, and irregularly undulated. The upper surface of the leaves is a darker green, and the bottom is a light green.[10] 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 have a pleasing odour; are trumpet-shaped, white to creamy or violet, and 6 to 9 cm (2+1⁄2–3+1⁄2 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 five sharp teeth. The corolla, which is folded and only partially open, is white, funnel-shaped, and has prominent ribs. The flowers open at night, emitting a pleasant fragrance, and are fed upon by nocturnal moths.

Uses:- One of the primary active agents in Datura is atropine which has been used in traditional medicine and recreationally over centuries. The leaves are generally smoked either in a cigarette or a pipe. During the late 18th century, James Anderson, the English Physician General of the East India Company, learned of the practice and popularized it in Europe. The Chinese also used it as a form of anesthesia during surgery
