Nutraceuticals 
Prospects, Sources and Role in Health and Disease

Bioactive phytochemicals contribute immensely to the operations and functions that occur within human beings. Scientists have coined the term "nutraceuticals" to describe any plant-based biochemical substances that positively affect physical condition and status. They promote health benefits and serve many purposes, such as acting as antioxidants, cancer inhibitors, hepatoprotectants, hypertensive inhibitors, and possessing antidiabetic and antidepressant properties, among other qualities. With these characteristics in mind, the authors describe how these nutraceuticals aid in the prevention and treatments of diseases. The authors intend for their research to aid in the further exploration and discovery of new drug designs and applications for nutraceuticals.
