White Willow Bark Extract: Nature’s Ancient Answer to Modern Discomforts

1. What is White Willow Bark Extract?
White Willow Bark Extract (Salix alba) is a bioactive botanical derived from the bark of the white willow tree. Historically revered as “nature’s aspirin,” its primary active constituent, salicin, undergoes metabolism to salicylic acid, delivering analgesic, anti-inflammatory, and antipyretic effects. Unlike synthetic NSAIDs, it offers a gentler, time-released action, making it a cornerstone of evidence-based phytotherapy.

  • МВ: 286.28 g/mol

  • EINECS: 205-331-3

  • Външен вид: Fine, hygroscopic powder; light tan to off-white

  • Разтворимост: Soluble in water, ethanol; insoluble in non-polar solvents
