The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Description of Plant(s) and Culture

Woody Nightshade

Any of several of the plants of the genus Solanum are called nightshade.

Solanum dulcamara is shrubby, thumb-thick, ashy-green, somewhat angular, climbing stem can reach a length off up to 10 feet. The dark green (or purplish when young) leaves are alternate and variable in shape (may be cordate, landeolate-ovate, or hastate). The purple, star-shaped flowers appear in paniculate clusters on shore lateral or terminal peduncles from May to August. The fruit is a scarlet, bitter berry that hangs on the vine for months after the leaves have fallen.

Solanum nigrum (black nightshade): its erect, angular, branching stem grows 1 to 2 feet high and may be glabrous or covered with inward bent hairs. The leaves are alternate, dark green, ovate, and wavy-toothed or nearly entire. Drooping, lateral, umbel-like clusters of white or pale violet flowers appear from July to October. The fruit is a many-seeded, pea-sized, purple or black berry.

Solanum dulcamara:
Although bittersweet nightshade is a relatively weak poison, it is used almost exclusively for external problems. Use it as a poultice for gout, herpes, furuncles, warts, ringworms, shingles, old ulcers, and felons. Combined with chamomile it makes a good ointment for swellings, bruises, sprains, and corns. For skin diseases and sores, combine with yellow dock.

Dulcamara is used as a starting material for steroids and is confirmed by scientists to be significant in anti-cancer activity.

Solanum nigrum:
Taken internally in very small amounts, the leaves strongly promote perspiration and purge the bowels the next day. The juice of the fresh herb is sometimes used for fever and to allay pain. In large doses, black nightshade can cause serious, but usually not fatal, poisoning. Externally, the juice or an ointment prepared from the leaves can be used for skin problems, cancers, and tumors. The berries are poisonous, but boiling apparently destroys the toxic substances and makes them usable for preserves, jams, and pies. Extracts used in tea in India, China, Europe, Japan, Africa, etc.
