herbs - Berberis (Berberis vulgaris).

What Is It?

Berberis or barberry, is a perennial shrub, native to Europe. The bark, root, red berries and leaves are used in herbal medicine. The plant is closely related to the North American species, Berberis aquifolium (Oregon grape).

Action

This plant contains a potent antibacterial alkaloid, called berberine, a component also found in goldenseal. This constituent is effective against many pathogens such as E-coli and salmonella. Berberine has a stimulating action on the immune system, liver and gall bladder (helping to improve the flow of bile). In addition, it has antimicrobial, anticonvulsant, sedative, antitumour, hypotensive and febrifuge properties (reduces fever). It also contains an antioxidant alkaloid called berbamine, which has anti-inflammatory properties. The herb is is also said to be a bitter herb, and a tonic to spleen, pancreas and the digestive system.
