Traditional uses of Goldenseal:

Goldenseal is a rich source of berberine. It also abounds in other isoquinoline alkaloids such as hydrastin and canadine, as well as fatty compounds, mineral salts, fisterols, essential oils, resins and chlorogenic acid. Goldenseal is recognized as one of the best natural antibiotics. It has a healing effect on all mucous membranes in the body. Thanks to the presence of berberine, it exhibits properties against Chlamydia pneumoniae. Effectively eliminates the colonies of Candida fungi and numerous bacteria, but does not destroy the useful flora. Berberine, which is the main ingredient of Goldenseal, has a positive effect on the intestinal microflora, restoring its proper balance. The herb is also used in upper respiratory congestion, due to its expectorant and antitussive activity.


Goldenseal cannot be used by pregnant or lactating women. It cannot be taken by people with high blood pressure, hypoglycemia (low glucose level) or enzymatic insufficiency. It should not be used by people with autoimmune disease such as multiple sclerosis or lupus.
