1. Treatment of fever, colds and infections

As a 'Natural Aspirin', Salicylin(Salicin) is used to treat mild fever, colds, infections (influenza), acute and chronic rheumatic discomfort, headache and pain caused by inflammation. Aspirin (acetylsalicylic acid), as a synthetic substitute of salicylin, has potential dangerous side effects on gastrointestinal tract. As its natural configuration, salicin can be harmlessly transformed into salicylic acid in blood and liver through the gastrointestinal system. The transformation process takes hours, so the results are not immediately felt by the human body, but the general effect lasts for hours.

2. Alleviate arthritis pain and back pain

Salicin is believed to be the source of Salix peel's ability to resist inflammation and relieve pain. The analgesic effect of willow bark is usually slower but lasts longer than that of ordinary aspirin products. One trial found that a herbal compound containing 100ng salicin could effectively improve the analgesic ability of patients with arthritis after two months of continuous administration. Another experiment found that a daily intake of 1360 mg Salix bark extract (containing 240 mg salicylin) for two weeks had better efficacy in treating joint pain and/or arthritis. The use of high doses of Salix peel extract may also help relieve low back pain. A four-week trial found that Salix peel extract containing 240mg salicin could effectively reduce the deterioration of low back pain.
