Willow bark is traditionally used for pain and conditions of inflammation. According to one controlled clinical trial, use of high amounts of willow bark extract may help people with low back pain. One trial found 240 mg of salicin from a willow extract to be more effective than 120 mg of salicin or a placebo for treating exacerbations of low back pain.⁵

Willow has anti-inflammatory and pain-relieving properties. Although pain relief from willow supplementation may be slow in coming, it may last longer than pain relief from aspirin. One double-blind trial found that a product containing willow along with black cohosh, guaiac (Guaiacum officinale, G. sanctum), sarsaparilla, and aspen (Populus spp.) bark effectively reduced osteoarthritis pain compared to placebo.⁶ Another trial found that 1,360 mg of willow bark extract per day (delivering 240 mg of salicin) was somewhat effective in treating pain associated with knee and/or hip osteoarthritis.⁷

 

Although willow is slow acting as a pain reliever, the effect is thought to last longer than the effect of willow’s synthetic cousin, aspirin. One double-blind trial found that willow bark combined with guaiac, sarsaparilla, black cohosh, and poplar (each tablet contained 100 mg of willow bark, 40 mg of guaiac, 35 mg of black cohosh, 25 mg of sarsaparilla, and 17 mg of poplar) relieved pain due to RA better than placebo over a two-month period.⁸ The exact amount of the herbal combination used in the trial is not given, however, and patients were allowed to continue their other pain medications. Clinical trials on willow alone for RA are lacking. Some experts suggest that willow may be taken one to four weeks before results are noted.⁹

 

While there have been few studies on herbal therapy for bursitis, most practitioners would consider using anti-inflammatory herbs that have proven useful in conditions such as rheumatoid arthritis. These would include boswellia, turmeric, willow, and topical cayenne ointment.

As early as 1763, use of willow bark to decrease pain and inflammation was reported.¹¹ Its constituents are chemically related to aspirin. These constituents may decrease pain by two methods: by interfering with the process of inflammation, and by interfering with pain-producing nerves in the spinal cord.¹² No human studies have investigated the pain-relieving potential of willow bark, and questions have been raised as to the actual absorption of willow bark’s pain-relieving constituents.¹³ The potential pain-reducing action of willow is typically slower than that of aspirin.
