Huang Bai, also known as Amur Cork Tree Bark (Phellodendron amurense), is a traditional Chinese medicinal herb valued for its anti-inflammatory, antimicrobial, and detoxifying properties. In herbal medicine, it’s often used to “clear heat” and “dry dampness,” making it a common ingredient in formulas for skin irritation, urinary tract issues, and digestive imbalances. Modern studies suggest it contains compounds like berberine, which may help support immune function and combat bacterial and fungal infections.
