Modern day science is now here to back up these long-known medicinal qualities. Our birch sap naturally contains quantifiable amounts of salicylates, resveratrol, betulinic acid, and lupeol which can act to help fight inflammation, regulate metabolism, detoxify the body, all while providing a refreshingly great drinking experience.
