Presently “nutraceuticals” are globally recognized as play a major role in health improvement. The concept of “Nutraceticals” was introduced by Dr Stephen DeFelice in 1989 as combining term of “Nutrition” and “Pharmaceutical” together. Therefore, “nutraceutical” is any material which may be included a food or its part which provides health or medical benefits, prevention and treatment of diseases.
