Introduction
Man is the most evolved animal on earth and thus could be considered as the fittest living being nature has ever produced. Using the vast knowledge that nature has endowed him with, man has further shored his own defenses by an impressive range of weaponry. Yet, sadly all his ammunitions fails when it comes to defending his own body against the multitude of invisible, microscopic, disease causing organisms and molecules that surrounds him (Phondke, 1992). We are floating in an ocean of enemies of cunning microbes along with some deadly other factors such as automobile exhaust, radiation, cigarette smoke, pesticides etc. that result in the formation of free radicals. Free radicals damage the natural metabolic process in cell by damaging cell membrane, proteins, fats, nucleic acids in the cell and cause several disorders such as Cancer, Parkinson’s disease, Alzheimer’s disease, myocardial infarction, premature aging, age-related macular degeneration (ARMD) and cataracts.
