WILLOW BARK OVERVIEW INFORMATION
Willow bark is the bark from several varieties of the willow tree, including white willow or European willow, black willow or pussy willow,crack willow,purple willow, and others. The bark is used to make medicine.

Willow bark acts a lot like aspirin, so it is used for pain, including headache, muscle pain, menstrual cramps, rheumatoid arthritis (RA), osteoarthritis, gout, and a disease of the spine called ankylosing spondylitis.

Willow bark’s pain relieving potential has been recognized throughout history. Willow bark was commonly used during the time of Hippocrates, when people were advised to chew on the bark to relieve pain and fever.

Willow bark is also used for fever, the common cold, flu, and weight loss.

Salicin, the active ingredient in willow bark, seems to have contributed to the death of the composer, Ludwig von Beethoven. Apparently, Beethoven ingested large amounts of salicin before he died. His autopsy report is the first recorded case of a particular type of kidney damage that can be caused by salicin.

 

Health Benefits of White Willow Bark

1) Arthritis

In a German study, the effectiveness of a willow bark extract providing 240 mg of salicin a day was compared to placebo in a 2-week randomized controlled trial in 78 people with osteoarthritis.After two weeks, the willow bark patients' pain scores were reduced by 14% compared to the placebo group,which had a 2% increase in pain scores.

Two randomized controlled 6-week trials investigated the effectiveness and safety of willow bark in 127 patients with hip and/or knee osteoarthritis and 26 patients with rheumatoid arthritis. In the osteoarthritis trial, patients received either willow bark providing 240 mg of salicin a day, 100 mg a day of the drug diclofenac, or a placebo. Patients in the rheumatoid arthritis trial received either willow bark or a placebo. The results found that the drug diclofenac was more effective than placebo in osteoarthritis patients but white willow bark was not. In rheumatoid arthritis patients, willow bark wasn't found to be more effective than placebo.

2) Low Back Pain

A randomized controlled trial published in the American Journal of Medicine examined the use of 120 mg or 240 mg salicin or placebo in 210 patients with an low back pain. In the fourth and final week of the study,39% of the group taking 240 mg salicin were pain-free for at least 5 days, compared to 21% in the 120 mg group and only 6% in the placebo group.
