Herbs and shrubs were always considered to be rich source of many bioactive components. Herbal medicine is still the mainstay of about seventy five to eighty percent of the world population, mainly in the developing countries, for primary health care because of better cultural acceptability, better compatibility with the human body and lesser side effects. However, the last few years have seen a major increase in their use in the developed world (Kamboj et al., 2000). Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. They are also known as free radical scavengers (Valko et al., 2007; Diplock et al., 1998; Davis et al., 2012).
