Martins, Natália; Barros, Lillian; Santos-Buelga, Celestino; Ferreira, Isabel C. F. R.Reactive species, including free radicals, have been implicated in ageing and various diseases. The human body possesses an antioxidant defense system that acts in the detoxification and elimination of those species. Nevertheless, natural matrices can give an exogenous contribution, providing antioxidant biomolecules such is the case of phenolic compounds. Origanum vulgare L. (oregano) could be one of those mat...
