A wide range of health benefits have been attributed to wheatgrass, the young grass of the common wheat plant Triticum aestivum. Its components include chlorophyll, flavonoids, and vitamins C and E. Forms of wheatgrass include fresh juice, frozen juice, tablets, and powders.
The popularity of wheatgrass continues to grow. The advantages seen in the clinical trials need to be proved in larger studies before clinical recommendations for the public can be given.
