Goldenseal is a powerful antimicrobial herb native to North America, with a bright yellow root that has been used by Native Americans and early American physicians for centuries. This potent herb contains berberine—a compound with remarkable antibacterial, antifungal, and immune-stimulating properties. Goldenseal is particularly valued for mucous membrane infections: sinus infections, sore throats, urinary tract infections, and digestive infections. It's also used topically for wounds and skin infections. Due to overharvesting, goldenseal is now at risk in the wild—choose sustainably cultivated sources. This is a short-term remedy for acute infections, not for long-term daily use.
