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

Designating a family of dictyledonous herbs, shrubs, and trees, including frangipani and periwinkle.

Dogbane is a bushy, shrub-like, perennial, hairless plant with tough fibrous bark on the stems, exuding milky latex juice when broken.

A large, horizontal, milky rootstock sends up a glabrous stem with tough, fibrous bark to a height of 1-4 feet. The leaves are opposite, roundish to oblong-ovate or ovate, dark green above, lighter and hairy beneath, and grow on short, reddish petioles. The nodding bell-shaped, drooping, fragrant flowers grow in terminal cymes and are pink outside, pink and white striped inside or pink with red markings inside. Blooming time is May to August. The fruit is a pair of long, slender pods. All parts of the plant contain a milky juice.

This plant, dogbane, differs from its close relative Indian Hemp (A. cannabinum) in that its leaves are mostly sessile (stalkless), and the flowers are both in leaf axils and terminal.

Another plant is also called bitterroot (Lewisia rediviva) was commonly eaten by the Native Americans in Montana.
