Wheatgrass is a kind of grass. The above-ground parts, roots, and rhizome are used to make medicine. Wheatgrass is primarily used as a concentrated source of nutrients. It contains vitamin A, vitamin C, and vitamin E, iron, calcium, magnesium, and amino acids.
Wheatgrass is taken by mouth to increase production of hemoglobin, the chemical in red blood cells that carries oxygen; improve blood sugar disorders, such as diabetes; prevent tooth decay; improve wound healing; and prevent bacterial infections.
It is also taken by mouth to remove deposits of drugs, heavy metals, and cancer-causing agents from the body; and to remove toxins from the liver and blood.
Some people take wheatgrass by mouth to prevent gray hair, reduce high blood pressure, improve digestion, and lower cholesterol by blocking its absorption.
Wheatgrass is also taken by mouth to treat various disorders of the urinary tract, including infection of the bladder, urethra, and prostate; benign prostatic hypertrophy (BPH); kidney stones; and in "irrigation therapy," the use of a mild diuretic along with lots of fluids to increase urine flow.
Other uses include treatment of respiratory tract complaints, including the common cold, cough, bronchitis, fever, and sore throat; tendency toward infection; gout; liver disorders; ulcerative colitis; joint pain; and chronic skin problems.
Wheatgrass is used for cancer and arthritis in alternative treatment programs. Wheatgrass contains a lot of chlorophyll, the chemical in plants that makes them green and also allows them to make energy from sunlight through photosynthesis. Some people think chlorophyll might fight cancer and arthritis.
Wheatgrass juice is a popular health drink. It is thought to benefit health only when fresh and taken on an empty stomach immediately after extraction. But there is no research to date that supports this.
Wheatgrass cream is applied to the bottom of the feet to treat heel pain.
In foods and beverages, wheatgrass extracts are used as a flavoring component.
How does it work?
Wheatgrass contains chemicals that might have antioxidant and anti-inflammatory (swelling) activity, which is why some people think it might be helpful for ulcerative colitis. It also contains a chemical that seems to kill bacterial infections.
