Willow Bark
Willow bark (scientific name Salix) is a plant found in the Mediterranean region usually used in weight loss and to treat fever and inflammatory conditions. The antipyretic and anti-inflammatory characteristics are likely due to the salicin content, which is a salicylate glycoside.
Multiple studies support willow bark is effective in treating low back pain, osteoarthritis, and rheumatoid arthritis.
The mechanism of willow bark in weight loss is theorized to be due to pain relief resulting in increased mobility, exercise performance, and energy consumption.
This supplement should be avoided during breastfeeding or children because it contains salicylic acid, which can induce Reye's syndrome. Because willow bark contains salicin, those allergic to aspirin and salicylic acid should not use this supplement.
Other warnings have been issues regarding the use of willow bark with gastritis, stomach ulcers, diabetes, asthma, or hemophilia. Willow bark may also interact with anticoagulants, beta blockers, and diuretics but changing their effectiveness, and increasing the risk of stomach bleeding if combined with NSAIDS [35].
