Willow Bark Extract Relieves Low Back Pain
This is really not a big shocker, considering that aspirin was actually derived from a substance found in willow bark.
Am J Med 2000;109:9-14 Willow bark extract is more effective than placebo for the reduction of low back pain, according to the results of a double-blind study. The extract was well tolerated, with only one patient experiencing allergy symptoms that were possibly related to willow bark. The symptoms disappeared 2 days after treatment was stopped. “The low incidence of adverse events observed in this and other studies suggests willow bark extract may be an effective alternative, especially in patients who cannot tolerate nonsteroidal anti-inflammatory drugs,” the authors write.
