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

Red Alder

Red Alder

Black alder (A. glutinosa) is a deciduous tree up to 80 feet high; the alternate leaves are round-obovate, usually doubly serrate, scalloped, and have a tuft of down on the underside. The flowers are segregated by sex into separate catkins, the reddish-purple female ones developing into hard cones that contain the seeds. 2-8 catkins will occur in a cluster on a forked peduncle.

Red alder (A. rubra) grows as a shrub or tree. It has elliptic-ovate leaves that are dark green on top and rusty-haired underneath. Found in evergreen and redwood forests from Northern California to Alaska. Uses and dosage is the same as A. glutinosa.

Smooth alder (A. serrulata) sometimes called the Hazel alder, is a shrub or tree with blackish bark that is lightly speckled with small, grayish to orange lenticels. Its leaves are elliptic to obovate, finely serrate and usually fine-haired underneath. It can be found from Nova Scotia to Oklahoma, Florida, and Louisiana. Medicinally used the same as black alder.
