Willow bark tea is commonly thought to be both a pain reliever and fever reducer. The salicylic acid in this bark is the same found in most other pain relievers, such as aspirin, and is often used to relieve lower back pains. Making a cup of willow bark tea is simple, but it is fairly different from the usual tea bag and microwave brands.
Heat water in a cooking pot or tea kettle until it comes to a boil. Stir in 1 to 2 teaspoons of willow bark for every 8 ounces of water. White willow bark steeps easily.
Allow the bark and water to simmer for 10 to 15 minutes. This varies depending on the amount of tea being made. The more tea, the longer it should simmer.
Steep for about 30 minutes. Allow more steeping time for greater quantities and stronger tea.
The website of the University of Maryland Medical Center recommends drinking three to four cups daily as a pain reliever. It's otherwise commonly enjoyed before bed, with breakfast or as a traditional afternoon tea.
