Please read before use: the information provided below describes traditional and informational uses—it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek professional advice before use.

Enhanced precautions for this plant: Not recommended during pregnancy and breastfeeding due to the presence of berberine, an alkaloid with reported uterotonic effects. Do not use in young children without advice from a healthcare professional. Berberine may interact with several medications (anticoagulants, diabetes treatments, certain antibiotics): seek advice before any prolonged use. Avoid prolonged internal use without supervision, due to the risk of digestive and hepatic irritation at high doses.

Decoction — Dried root bark

Traditional root decoction

Gently boil crushed root bark in water for approximately fifteen minutes, then let it steep off the heat before straining. This preparation was traditionally used externally as compresses or diluted as a mouthwash. Dosage should be validated with a healthcare professional or recognized pharmacopeia before use.

Tincture — Root or root bark

Root mother tincture

Fresh or dried root is macerated in alcohol for several weeks according to traditional herbal methods, then filtered. This concentrated form was reserved for use supervised by an experienced practitioner, due to its alkaloid content. Dosage should be validated with a healthcare professional or recognized pharmacopeia before use.

Ointment — Root bark extract

Traditional skin ointment

Root extract was incorporated into a fatty base (animal fat or beeswax) to obtain an ointment applied locally to irritated skin areas, according to practices reported by herbalists of the American West. Dosage should be validated with a healthcare professional or recognized pharmacopeia before use.
