Natural source of salicin, the precursor to aspirin
We rank Willow Bark by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Willow Bark is a natural plant extract. It contains salicin, which is a precursor to aspirin; this means it is a substance that the body converts into a chemical similar to the active ingredient found in aspirin.
It is primarily used as a natural alternative for managing pain and inflammation. Because it contains salicin, it is often taken to help reduce discomfort or fever.
The inner bark is harvested from willow trees and dried. This material is then ground into a powder or soaked in a solvent to create a concentrated extract, which is then put into capsules or tablets.
This ingredient is generally mid-range in price. This is because the raw bark must be harvested from specific tree species and processed into a concentrated form, which is more involved than producing basic mineral supplements but less costly than complex synthetic compounds.
