Recognized as an antioxidant, the most notable benefit of Carnosic acid is its ability to protect against free radicals in the brain. The action of free radicals in the body gives rise to a number of diseases such as cancer, diabetes, and heart disease. In brief, a free radical is an atom that has an odd number of electrons, leaving one of them unpaired. Consequently, the atom snatches an electron from another atom to match up with its odd electron, turning the second atom into a free radical as well. This process continues, causing a destructive chain reaction on a molecular level, which ultimately results in damage to the cells.
