What is White willow bark?

  • – White willow bark, also known as Salix alba, has a long history usage of herbal remedies for pain and inflammation. It was commonly used as an analgesic and antipyretic agent in ancient Egyptian, Roman, Greek, and Indian civilizations. It was commonly used for the treatment of inflammatory syndromes when aspirin was found to have gastric side effects. The mechanism of white willow bark’s action is similar to aspirin which is a nonselective inhibitor of COX1 and COX2, which can block inflammatory prostaglandins. The main active ingredient is salicin, which can be converted to salicylic acid by liver and is believed to have less side effects than aspirin. Different randomized, placebo controlled studies have shown that white willow bark have similar efficacy compared to nonsteroidal agents includes aspirin. [1]
