Aspirin (Acetylsalicylic acid) is a synthetic substitute for Salicin. Salicin from White Willow Bark passes through the entire digestive tract without causing damage and is converted into natural aspirin in the liver. It provides all the pain relief of a regular aspirin. Willow bark can best taken in a distilled tincture form.

What is Willow Bark?
Willow bark, the bark of several varieties of the willow tree, has been used for centuries as a pain reliever. The active ingredient in the medicine made from Willow Bark is called Salicin.

Some people use Willow Bark as an alternative to aspirin, particularly those that experience chronic headaches or back pain.
It comes from the branches of 2- to 3-year-old willow trees. Willow trees and shrubs grow all over the world, except for Australia and Antarctica. The white willow and black willow are two of the most common willows that are used medicinally.

Properties of White Willow Bark
Willow Bark can also be used to relieve menstrual cramps and bring down a fever. The salicin inside willow bark works the same way as aspirin, by reducing inflammation and pain as it enters your bloodstream. Because of the anti-inflammatory properties of Willow Bark, it may be especially effective in combatting joint pain as well.

So, if you’re looking for an alternative to aspirin, you could consider Willow Bark. I recommend to look for the organic ones.
While it may be an effective alternative to aspirin, talk to your doctor before choosing to take Willow Bark.
