Rosemary Oleoresin is extracted from Rosemary, an aromatic woody, perennial with fragrant, evergreen, needle-like leaves.
Historical uses and applications for Rosemary and Rosemary Oleoresin from times gone by were for relieving sore muscles, for memory and adding to salves, lotions, creams as an aromatic antioxidant. As chemists learned more about the active ingredients in Rosemary Oleoresin Extract, specifically the carnosic acid, Rosemary Oleoresin Extract, ROE, became more popular in a wide range of products mainly soap making, lotions, etc... due to the carnosic acid properties. And in Japan and Europe Rosemary Oleoresin is also an approved food additive (certain properties must be present) due chiefly to the properties of the carnosic acid and its strong antioxidative properties. (There are some reports it also has antimicrobial properties.)
In addition to Carnosic Acid, Rosemary Oleoresin extract also contains Rosmarinic Acid, Rosmaridiphenol, Carnosol, Rosmanol, and Rosmaridiquinone.
