Wheat grass can be traced back in history over 5000 years, to ancient Egypt and perhaps even early Mesopotamian civilizations. It is purported that ancient Egyptians found sacred the young leafy blades of wheat and prized them for their positive effect on their health and vitality.heatgrass is allowed to grow longer than malt. Like most plants, it contains chlorophyll, amino acids, minerals, vitamins, and enzymes. Claims about the health benefits of wheatgrass range from providing supplemental nutrition to having unique curative properties, though few, if any, have been scientifically proven.
