Wheatgrass refers to "the young grass of the common wheat plant, Triticum aestivum, that is freshly juiced or dried into powder for animal and human consumption. Both provide chlorophyll, amino acids, minerals, vitamins, and enzymes."

According to Living-Foods.com, wheatgrass in juice form contains 70% chlorophyll, "which is often referred to as the blood of plant life. It closely resembles the molecules of' human red blood cells. Chlorophyll has been shown to produce an unfavorable environment for bacterial growth in the body and therefore effective in increasing the body's resistance to illness." They add: "Wheatgrass is considered to be a complete food in itself. The fact is that one pound of fresh wheatgrass is equivalent in nutritional value to 23 pounds of choice garden vegetables." But keep this in mind: "Due to its fibrous nature, which is indigestible by humans, wheatgrass must be liquefied before it can be consumed."
