A natural sweetener from Birch trees.
Xylitol is a naturally occurring alcohol found in most plant material, including many fruits and vegetables. It is extracted from birch wood to make medicine.
Xylitol is widely used as a sugar substitute and in "sugar-free" chewing gums, mints, and other candies. However, sorbitol is the most commonly used sweetener in sugarless gums because it is less expensive than xylitol and easier to make into commercial products.
