Abstract
            Free radicals are constructed by natural physiological activities in the human cells as  well as in the environment. They may be produced as a result of diet, smoking, exercise,  inflammation, exposure to sunlight, air pollutants, stress, alcohol and drugs. Imbalanced  redox status may lead to cellular oxidative stress, which can damage the cells of the body,  resulting in an incidence of various diseases. If the endogenous antioxidants do not stop the  production of reactive metabolites, they will be needed to bring about a balance in redox  status. Natural antioxidants, for example plants, play an important part in this context.  This paper seeks to report the available evidence about oxidative stress and the application  of plants as antioxidant agents to fight free radicals in the human body. For this purpose,  to better understand oxidative stress, the principles of free radical production, the role of  free radicals in diseases, antioxidant defense mechanisms, and the role of herbs and diet in  oxidative stress are discussed.
        
        
 
        
	
            
            Implication for health policy/practice/research/medical education:  
  This review highlights the available evidence about oxidative stress and the application of plants as antioxidant agents to fight  free radicals in the human body. Also, the role of free radicals in diseases, antioxidant defense mechanisms, and the role of herbs  and diet in oxidative stress were discussed.
