Traditional Uses: Traditionally used by Native American tribes and later in European herbalism as an astringent for treating hemorrhoids, skin inflammation, minor wounds, insect bites, varicose veins, and as a cooling agent for burns and perineal discomfort after childbirth.
Potential Benefits: Modern research confirms the bark extract possesses potent anti-inflammatory, antioxidant, and wound-healing properties; it inhibits inflammatory mediators (IL-6, IL-17C, TSLP) in skin cells, promotes keratinocyte migration for wound repair, and demonstrates antimicrobial activity against Staphylococcus aureus.
Warnings: For topical use only; internal use is not recommended due to tannin content; safety during pregnancy and breastfeeding is not established—avoid use; may cause allergic contact dermatitis in sensitive individuals, with possible cross-sensitivity to plants like arnica and chamomile.
