White willow bark is harvested from the dried bark of young branches or twigs of the trees, usually in early spring or autumn. It belongs to the willow family1. Historical records show that white willow bark has been used for thousands of years in ancient China, Egypt, Greece and South Asia, to relieve headaches, reduce fever, lessen muscle ache and pain and to support various other illnesses.2 Indeed, anecdotal accounts of willow bark extract being used as a medicine have occurred since written records began, in the time of Hippocrates (400BC) when physicians advised their patients to chew the bark to reduce fever and inflammation.3
