Goldenseal (Hydrastis canadensis) has long been used in traditional herbal medicine as a “mucus membrane tonic,” particularly for respiratory and digestive tract conditions involving excess mucus and inflammation.
Herbal practitioners believe its astringent properties help dry excess secretions and soothe irritated mucous membranes, while laboratory studies suggest that its active compounds, including berberine and hydrastine, possess antimicrobial and anti-inflammatory effects. Goldenseal is commonly consumed as teas, tinctures, extracts, or capsules and is often combined with echinacea for immune and sinus support.
