Barberry: The Vitamin C-Rich Berry with Powerful Antimicrobial & Metabolic Benefits

European barberry (Berberis vulgaris) is a thorny shrub bearing tart, edible berries. Its root, bark, and fruit contain berberine—an alkaloid with demonstrated antiviral, antibacterial, and antifungal activity—making it a multifaceted traditional remedy.

Arthritic Pain Relief

Berbamine (another alkaloid) shows anti-inflammatory activity; may help gout and arthritis.

Other Potential Benefits
