Wheatgrass is the freshly sprouted first leaves of the common wheat plant (Triticum aestivum), used as a food, drink, or dietary supplement. Wheatgrass is served freeze dried or fresh, and so it differs from wheat malt, which is convectively dried. Wheatgrass is allowed to grow longer and taller than wheat malt. Like most plants, wheatgrass 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, but these claims have not been scientifically proven. Wheatgrass juice is often available at juice bars, and some people grow and juice their own in their homes. It is available fresh as produce, in tablets, frozen juice, and powder. Wheatgrass is also sold commercially as a spray, cream, gel, massage lotion, and liquid herbal supplement. Because it is extracted from wheatgrass sprouts (that is, before the wheat seed or "berry" begins to form), wheatgrass juice is gluten free, but some dietitians recommend that those with celiac disease avoid it due to the risk of cross-contamination. History Wheatgrass is traditionally used in both Persian and Indian festivals and rituals. Hindu sow wheat or barley seeds on the first day of Navaratri pooja and offer the saplings to the mother goddess on the last day as part of the rituals. However, the consumption of wheatgrass in the Western world began in the 1930s as a result of experiments conducted by Charles Schnabel in his attempts to popularize the plant. By 1940, cans of Schnabel's powdered grass were on sale in major drug stores throughout the United States and Canada. Ann Wigmore was also a strong advocate for the consumption of wheatgrass as a part of a raw food diet. Wigmore, founder of the Hippocrates Health Institute, believed that wheatgrass, as a part of a raw food diet, would cleanse the body of toxins while providing a proper balance of nutrients as a whole food. She also taught that wheatgrass could be used to treat those with serious disease. Both of these claims are believed by many reputable health institutes to be entirely unfounded by facts, and possibly dangerous. Cultivation Wheatgrass can be grown indoors or outdoors. A common method for sprout production indoors is often on trays in a growth medium such as a potting mix. Leaves are harvested when they develop a "split" as another leaf emerges. These can then be
