White willow
White willow, chemically related to aspirin, is traditionally used for pain. It has even been shown to be effective for cluster and tension headaches. White willow has a long history of medicinal use—dating back more than 5,000 years. Its roots go back to Europe and Central Asia, where it was used as a powerful pain relief remedy. Ancient Egyptians were said to value white willow for its analgesic and inflammation-busting properties.
