Efficacy and Safety of White Willow Bark (Salix alba) Extracts
Phytotherapy research : PTR (2015) · Review
In recent years, various in vitro and animal studies have demonstrated that the anti-inflammatory activity of willow bark extract is associated with down regulation of the inflammatory mediators tumor necrosis factor-α and nuclear factor-kappa B.

The historical analysis of aspirin discovery, its relation to the willow tree and antiproliferative and anticancer potential
Cell proliferation (2006) · Review
For several millennia, the willow tree and salicin have been associated with salicylic acid, the key precursor molecule that has contributed to the discovery of acetylsalicylic acid, traded as aspirin.
The 800 mg point is a 2-year placebo-controlled trial in 622 people with knee osteoarthritis (PMID 19180484), where pain improved faster than on placebo as a secondary outcome and joint space loss was smaller. The 1,200 mg point is the GAIT trial of 1,583 people (PMID 16495392), where chondroitin alone was not significantly better than placebo for a 20% fall in knee pain (5.3 percentage points higher, P=0.17), so it is plotted flat, not higher. A meta-analysis restricted to large, sound trials found no effect on pain (PMID 17438317), and the Cochrane review found a small benefit in short, mostly low-quality trials (PMID 25629804). Side effects matched placebo in both trials. No trial compared doses.
The Cochrane review of herbal medicine for low back pain found that willow bark extract standardised to 120 or 240 mg salicin a day is probably better than placebo for short-term pain and rescue medication (two trials, 261 participants, moderate-quality evidence), with no significant adverse events (PMID 25536022). A systematic review of the same trials reports a dose-dependent analgesic effect, which is why 240 mg sits above 120 mg, with all studies at up to 240 mg salicin for up to 6 weeks and only minor adverse events (PMID 19140170). A general musculoskeletal pain curve was removed: in osteoarthritis the trials conflict, including a 2-week trial at 240 mg with a moderate effect (PMID 11406860), and no cited trial tested a second dose.
