White Willow Bark Extract: Nature’s Historical Reply to Fashionable 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. Traditionally revered as “nature’s aspirin,” its main lively constituent, salicine, undergoes metabolism to salicylic acid, delivering analgesic, anti-inflammatory, and antipyretic results. Not like artificial NSAIDs, it provides a gentler, time-released motion, making it a cornerstone of evidence-based phytotherapy.
