Fourth, the efficacy of salicin from white willow bark extract and its application in the field of cosmetics

  1. Treat fever, colds and infections

As a “natural aspirin”, salicin is used to treat mild fever, colds, infections (influenza), acute and chronic rheumatic discomfort, headaches and pain caused by inflammation. Aspirin (acetylsalicylic acid), as a synthetic substitute for salicin, has potentially dangerous gastrointestinal side effects. As its natural configuration, salicin can pass through the gastrointestinal system harmlessly and is converted into salicylic acid in the blood and liver. The conversion process takes several hours, so the result will not be immediately felt by the body, but the general effect will last for several hours.

  1. Relieve arthritis pain and back pain

Salicin is believed to be the source of white willow bark’s ability to fight inflammation and relieve pain. The analgesic ability of white willow bark usually takes effect more slowly but lasts longer than ordinary aspirin products. An experiment found that a class of herbal compound products containing 100ng salicin can effectively improve the analgesic ability of arthritis patients after two months of continuous consumption. Another test found that intake of 1360 mg of white willow bark extract (containing 240 mg of salicin) daily for two weeks has a better effect on the treatment of joint pain and/or arthritis. Using high-dose white willow bark extract may also help relieve back pain. A four-week trial found that white willow bark extract containing 240 mg of salicin can effectively reduce the deterioration of back pain.
