Certificate of Analysis



Studies investigating the effects of willow bark in people with osteoarthritis (“wear-and-tear arthritis”) has yielded mixed results.In a clinical trial published in Phytotherapy Research, a White Willow Bark Extractcontaining 240 milligrams (mg) of salicin daily was compared to a placebo in 78 people with osteoarthritis.3 After two weeks of treatment, pain scores (using the WOMAC osteoarthritis index) were reduced by 14 percent in the willow bark group compared to 2 percent in the placebo group.

The same was not seen in a six-week study published in the Journal of Rheumatology. For this trial, 127 people with knee osteoarthritis were given either 240 mg of salicin, 100 mg of the pain medication Voltaren (diclofenac), or a placebo.

2.Low Back Pain

The current body of evidence suggests that White Willow Bark Extract powder may be most effective in treating acute low back pain.In a 2016 analysis published in the journal Spine, researchers evaluated 14 previously published studies on herbal treatments for low back pain. Among their findings, the researchers reported that the bark of the white willow tree (Salix alba) consistently provided greater pain relief than a placebo.

With that being said, the quality of the reviewed studies was considered poor to moderate. Further research would be needed to determine how safe and effective willow bark may be in relieving low back pain.

3.Weight Loss

White Willow Bark Extract has been aggressively marketed in recent years as a weight loss supplement. The health claims were fueled by early research in which the combined use of willow bark and ephedra proved effective in enhancing athletic performance and burning fat.

Ephedra (known as ma huang in traditional Chinese medicine) has been banned in the United States since 2004 following a spate of sudden cardiac deaths in users. On its own, willow bark has not shown any weight loss properties despite its continued use in weight loss supplements.
