Willow bark extract, derived from the bark of certain willow trees, has been utilized for thousands of years in various traditional medicine systems. Historically, it was valued for its properties that were believed to support general well-being, particularly in relation to minor aches and discomforts. While willow bark extract has been traditionally used to soothe occasional inflammation and to provide comfort from fevers, its effectiveness is supported by a blend of historical use and limited modern clinical research. Today, it is also included in some products aimed at supporting fitness and weight management. Ongoing studies continue to explore the broad potential benefits of willow bark extract in various applications.
