Use of natural antioxidants to scavenge free radicals: a major cause of diseases.

Damage to cells caused by free radicals is believed to play a central role in the aging process and in disease progression. Antioxidants are our first line of defense against free radical damage, and are critical for maintaining optimum health and wellbeing. The need for antioxidants becomes even more critical with increased exposure to free radicals. Pollution, cigarette smoke, drugs, illness, stress, and even exercise can increase free radical exposure. Because so many factors can contribute to oxidative stress, individual assessment of susceptibility becomes important. Free radical scavenger may prevent the oxidative stress by peroxidation, inhibiting free radicals and also by other mechanism can prevent disease. Antioxidants are intimately involved in the prevention of cellular damage the common pathway for cancer, aging, and a variety of diseases. The present review article is an attempt to generate interest and awareness that, free radical is a major cause of many diseases.
