Also known as: Hydrastis canadensis, Yellow Root, Orange Root
Goldenseal is a North American woodland plant valued for its antimicrobial alkaloid berberine. It has traditionally been used for respiratory infections, digestive issues, and mucosal inflammation.
Goldenseal (Hydrastis canadensis) is a perennial herb native to the deciduous forests of eastern North America, where it was extensively used by Native American peoples for infections and inflammation. Its primary bioactive alkaloids are berberine and hydrastine. Berberine has demonstrated broad-spectrum antimicrobial activity against bacteria, fungi, and protozoa in vitro, as well as anti-inflammatory and blood-glucose-lowering effects. However, goldenseal root contains relatively low concentrations of berberine (2–6%) compared to other berberine-rich plants like Coptis chinensis. Clinical research specific to goldenseal is limited, and much of the evidence is extrapolated from berberine studies. Goldenseal is listed as a vulnerable species due to overharvesting; sustainably cultivated sources should be preferred.
Berberine in goldenseal inhibits the growth of Staphylococcus aureus, E. coli, and Candida species in vitro by disrupting bacterial cell membranes and inhibiting protein synthesis.
Goldenseal has been traditionally applied topically and taken orally for inflamed mucous membranes of the mouth, throat, and digestive tract, with astringent and anti-inflammatory properties.
