Black nightshade is a common herb or short-lived perennial shrub, found in many wooded areas, as well as disturbed habitats. It reaches a height of 30 to 120 cm (12 to 48 in), leaves 4 to 7.5 cm (1.5 to 3 in) long and 2 to 5 cm (1 to 2.5 in) wide; ovate to heart-shaped, with wavy or large-toothed edges; both surfaces hairy or hairless; petiole 1 to 3 cm (0.5 to 1 in) long with a winged upper portion. The flowers have petals greenish to whitish, recurved when aged and surround prominent bright yellow anthers. The berry is mostly 6 to 8 mm (0.3 to 0.8 in) diam., dull black or purple-black. In India, another strain is found with berries that turn red when ripe.


Sometimes Solanum nigrum is confused for the more toxic deadly nightshade, Atropa belladonna, in a different Solanaceae genus altogether. A comparison of the fruit shows that the black nightshade berries grow in bunches, the deadly nightshade berries grow individually.

Medicinal Action and Uses–-Narcotic, diuretic, sedative, antispasmodic, mydriatic. Belladonna is a most valuable plant in the treatment of eye diseases, Atropine, obtained during extraction, being its most important constituent on account of its power of dilating the pupil. Atropine will have this effect in whatever way used, whether internally, or injected under the skin, but when dropped into the eye, a much smaller quantity suffices, the tiny discs oculists using for this purpose, before testing their patient’s sight for glasses, being made of gelatine with 1/50000 grain of Atropine in each, the entire disk only weighing 1/50 grain. Scarcely any operation on the eye can safely be performed without the aid of this valuable drug. It is a strong poison, the amount given internally being very minute, 1/200 to 1/100 grain. As an antidote to Opium, Atropine may be injected subcutaneously, and it has also been used in poisoning by Calabar bean and in Chloroform poisoning.

Poisoning symptoms are typically delayed for 6 to 12 hours after ingestion. Initial symptoms of toxicity include fever, sweating, vomiting, abdominal pain, diarrhea, confusion, and drowsiness. Death from ingesting large amounts of the plant results from cardiac arrhythmias and respiratory failure. Livestock have also been poisoned from nitrate toxicity by grazing the leaves of S. nigrum.

Black nightshade is highly variable and poisonous plant experts advise to avoid eating the berries unless they are a known edible strain. The toxin levels may also be affected by the plant’s growing conditions. The toxins in Solanum nigrum are most concentrated in the unripe green berries, and immature fruit should be treated as toxic. Most cases of suspected poisoning are due to consumption of leaves or unripe fruit.

There are ethnobotanical accounts of S.nigrum leaves and shoots being boiled as a vegetable with the cooking water being discarded and replaced several times to remove toxins.
