Solanum nigrum

Solanum nigrum (also known as black nightshade, European black nightshade, or duscle) is a species of flowering plant in the family Solanaceae. It is native to Eurasia and introduced in the Americas, Australasia, and South Africa. Parts of this plant can be toxic to livestock and humans, and it is considered a weed.

Description

Solanum nigrum is an annual or sometimes biennial plant. It is erect, usually 30–120 cm high, and has a branching stem. The leaves are alternate, simple, ovate to heart-shaped, and have entire or wavy margins. The flowers are small with white petals and yellow stamens, and are grouped in loose, lateral clusters. The fruit is a round, smooth berry, black or purplish-black at maturity.

Distribution and habitat

Solanum nigrum is native to Eurasia and is widely naturalized in the Americas, Australasia, and South Africa. It grows in a variety of habitats, from open, disturbed areas to woodlands and riverbanks.

Uses

Despite its toxicity, Solanum nigrum has been used in traditional medicine for centuries. It has been used to treat a variety of conditions, including skin diseases, ulcers, fevers, and gout. However, the plant's safety and efficacy for these uses have not been clinically tested.

Toxicity

All parts of the plant can contain solanine, a toxic alkaloid. Symptoms of poisoning include dilated pupils, headache, confusion, and in severe cases, coma and death. However, the ripe berries are usually less toxic and are sometimes eaten, particularly in Eastern Europe.

Control

Control of Solanum nigrum is difficult due to its prolific seed production and its ability to regrow from root fragments. Methods of control include hand-pulling, mowing, and the use of herbicides.
