They are able to prevent organs from injury. Antioxidants are also recognized as "free radical scavengers." These potent agents, which frequently come from the vegetables and fresh fruits, prohibit and in some circumstances even prevent, the oxidation of various molecules throughout the body. Most of the most powerful antioxidants are detected in herbs. This is due to the fact that herbs are exposed to ultraviolet light, all throughout the day. Hence, the advantages of antioxidants are very important for good health, because if free radicals are left unopposed, they can cause a wide range of diseases and chronic illnesses.
