Wheatgrass is a food prepared from the cotyledons of the common wheat plant, Triticum aestivum. It is sold either as a juice or powder concentrate. Wheatgrass differs from wheat malt in that it is served freeze-dried or fresh, while wheat malt is convectively dried. Wheatgrass is also allowed to grow longer than malt is. It provides 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. Some consumers grow and juice wheatgrass in their homes. It is often available in juice bars, alone or in mixed fruit or vegetable drinks. It is also available in many health food stores as fresh produce, tablets, frozen juice and powder. Wheatgrass contains no wheat gluten.
The consumption of wheatgrass in the Western world began in the 1930s as a result of experiments conducted by Charles F. 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 
Schnabel's research was conducted with wheatgrass grown outdoors in Kansas. His wheatgrass required 200 days of slow growth, through the winter and early spring, when it was harvested at the jointing stage. He claimed that at this stage the plant reached its peak nutritional value; after jointing, concentrations of chlorophyll, protein, and vitamins decline sharply. Harvested grass was dehydrated and made into powders and tablets for human and animal consumption. Wheatgrass grown indoors in trays for ten days contains similar nutritional content. Wheatgrass grown outdoors is harvested, dehydrated at a low temperature and sold in tablet and powdered concentrates. Wheat grass juice powder (freshly squeezed with the water removed) is also available either spray-dried or freeze-dried.
Proponents of wheatgrass make many claims for its health properties, ranging from promotion of general well-being to cancer prevention. These claims have not been substantiated in the scientific literature. There is some limited evidence of beneficial pharmacological effects from chlorophyll, though this does not necessarily apply to dietary chlorophyll.
There are a number of other small studies and pilots on the possible benefits of wheatgrass juice. According to Memorial Sloan Kettering Cancer Center, there may be a need for further study of wheatgrass therapy for ulcerative collitis; they cite a small pilot study which showed regular wheatgrass juice therapy significantly reduced rectal bleeding and overall disease activity.
It has been claimed that wheatgrass helps blood flow, digestion and general detoxification of the body. These claims have not been reliably substantiated, or are no different from similar vegetables. However, in one pilot study of children with thalassemia (a hereditary form of anemia which often requires blood transfusions), of the patients who were given 100 ml of wheatgrass juice daily, half showed reduced need for transfusions. No adverse effects were observed. Another small study of transfusion-dependent patients suffering from myelodysplastic syndrome responded similarly to wheatgrass therapy; that is, the intervals between needed transfusions were increased. In addition, the chelation effect (removal of heavy metals from the blood) was studied for the same patients; the wheatgrass therapy showed a significant iron chelation effect.
In another pilot, which was not placebo controlled, breast cancer patients who drank wheatgrass juice daily showed a decreased need for blood- and bone marrow-building medications during chemotherapy, without diminishing the effects of the therapy.
The food has demonstrated in vitro cytotoxicity to HL-60 (Human promyelocytic leukemia cells).
Wheatgrass proponent Schnabel claimed in the 1940s that "fifteen pounds of wheatgrass is equal in overall nutritional value to 350 pounds of ordinary garden vegetables", a ratio of 1:23. Despite claims of vitamin and mineral content disproportional to other vegetables, the nutrient content of wheatgrass juice is roughly equivalent to that of common vegetables (see table 1).
Wheatgrass is also claimed to be superior to other vegetables in its content of vitamin B12, a vital nutrient. Contrary to popular belief, B12 is not contained within wheat grass or any vegetable, rather it is a byproduct of the microorganisms living on plants. Analysis of B12 content in wheatgrass has confirmed that it contains negligible amounts of the compound.[15

in every state he goes
a pain time froze
