Does Wheat Grass Really Work?

Wheat grass, or genus Agropyron, is the tender grassy stalk of the young wheat plant. If left to mature, the plant will eventually form a head filled with wheat kernels, but by then the plant is no longer viable for use in wheat grass preparations. Proponents of wheat grass make numerous claims as to its health benefits, but scientific studies backing those claims are lacking. Wheat grass is nutritious, however, and may be a beneficial addition to your diet. Talk with your doctor before using wheat grass to treat any medical condition.

Wheat Grass Properties

Wheat grass is a popular ingredient in "green drinks" for improving overall health, and, according to the "Gale Encyclopedia of Alternative Medicine," it does contain beneficial nutrients. These include vitamins C, E and K and numerous minerals, such as niacin, biotin, choline, lutein, copper, folic acid and calcium.

Potential Benefits

Although there is a lack of evidence, wheat grass may be beneficial in treating fatigue, aging and circulation disorders, according to the "Gale Encyclopedia." It may also improve energy, boost the immune system, protect the body against biological hazards and detoxify the liver. Additional anecdotal uses include the treatment of arthritis, allergies, cancer and diabetes, although there is no indication that the herb produces any beneficial effects in treating these conditions.

Dosage and Method

The usual way to consume wheat grass is to drink the fresh juice extracted from the tender stalks when they are approximately 8 inches high. A typical therapeutic dose is 100 to 300 ml per day. A wheat grass juicer is helpful in extracting the liquid from the stalks. Freeze-dried capsules and wheat grass tincture are also available in health food stores, but the preferred method of consuming wheat grass is in liquid form.

Considerations

Wheat grass juice has a strong taste that some may find disagreeable. The herb is generally safe, according to MayoClinic.com, but it may cause side effects in some, including headache, nausea and throat swelling. The stalks may contain mold or bacteria. Do not consume wheat grass if you have a grass allergy or a wheat allergy, and do not take the herb if you are pregnant or nursing.
