Function:
1. Treatments for fevers, colds and infections As ‘nature aspirin. Salicin is used to treat mild fevers, colds, infections (influenza), acute and chronic rheumatic disorders, headaches, and pain caused by inflammation. Aspirin (acetylsalicylic acid), a synthetic replacement for salicin, has potentially dangerous gastrointestinal side effects. In its natural form, salicin passes harmlessly through the gastrointestinal tract, converted to salicylic acid in the blood and the liver. The conversion process takes a few hours, so the results will not be felt immediately, but are normally sustained for several hours.
2. Pain Relief in Osteoarthritis and low back pain: Salicin is thought to be the source of the anti-inflammaory and pain-relieving actions of willow. The analgesic actions of willow are typically slow to develop but may last longer than the effects of standard aspirin products. One trial has found that a combination herbal product including 100 mg willow bark taken for two months improved functioning via pain relief in people with osteoarthritis. Another trial found that 1360 mg of willow bark extract per day (delivering 240 mg of salicin) for two weeks was somewhat effective in treating pain associated with knee and/or hip osteoarthritis. [5] Use of high amounts of willow bark extract may also help people with low back pain. One four-week trial found 240 mg of salicin from a willow extract was effective in reducing exacerbations of low back pain.
