White Willow Bark Extract
White Willow Bark extract is used as an alternative to aspirin because it is less irritating on the stomach lining.
Aspirin is a very well known ingredient in the famous "ECA Stack" because it has been known to help potentiate the power of stimulants. It also has a pain relieving function that can help someone focus.
Researchers have also suggested that white willow bark is more effective than aspirin because of other active compounds that are found in the bark but not the drug.
