Société Apothecary
White Willow Bark: Materia Medica Known as “nature’s aspirin,” White Willow Bark has long been revered for its ability to reduce pain, inflammation, and fever. Used in traditional European herbalism and Indigenous North American medicine, it is the original source of salicin, the compound that inspired the development of aspirin. “White Willow brings ease to aching joints and fiery discomfort—cooling, soothing, and grounding pain with the wisdom of the trees.” MATERIA MEDICA Latin Binomial: Salix alba Common Name(s): White Willow, Willow Bark, European Willow TCM Name: Bai Liu Shu Pi (白柳树皮) – used rarely Ayurvedic Name: Similar uses to herbs like Shallaki ( Boswellia ), though not native Family: Salicaceae Physical Description of the Plant: A graceful deciduous tree with narrow, lance-shaped leaves that are pale silvery-green underneath.
