White Willow bark provides salicin, which your body converts into a salicylate-like substance. People take it to temporarily ease joint discomfort and help muscles recover.
A standardized extract that lists a set amount of salicin is used, not raw bark by weight. Take it with food and water when needed, and do not exceed the duration stated on the label.
Avoid this supplement if you are allergic to aspirin or salicylates. Do not take it with blood thinners or NSAIDs. Speak with a doctor before mixing with other supplements. Do not use during pregnancy or breastfeeding. Those with stomach ulcers, kidney problems, or asthma should get professional advice first.
