Oats, Avena sativa L. [Fam. Gramineae], are widely used in human foods, animal feeds and livestock forages around the world. The use of oats for food and medicinal purposes dates to antiquity. Paleobotanists place this ancient cereal grass as being cultivated as early as 2000 B.C. Tinctures and extracts of oat straw and immature seed are readily available in Europe as a nervous system restorative, to assist convalescence and to strengthen a weakened constitution. Alternative practitioners in Europe sometimes recommend oat straw extract for treating multiple sclerosis. Oat straw is also used in Europe to treat shingles, herpes zoster, herpes simplex and neurasthenia. The Commission E approves oat straw for external use in treating inflammatory and seborrheic skin diseases, especially those with itching, similar to the popular use of colloidal oatmeal preparations. Several studies were conducted on oat grass extract for helping cigarette smokers to quit, but although the results were negative, researchers discovered an influence of the herb on reproductive hormones, including luteinizing hormone. Green oat grass (the grass before it matures into oat straw), like other grasses, is rich in vitamins including A, B, C, E, K and pantothenic acid and minerals, including iron (39mg/Kg dry weight), manganese (8.5mg) and zinc (19.2mg), silicon dioxide (2%), calcium, magnesium, phosphorus and potassium. As such, green oat grass juice can be used to treat avitaminosis. Oat grass is rich in protein, approximately 30%, and contains all the essential amino acids along with chlorophyll, flavonoids, lecithin and enzymes. This abundance of nutrients has made oat grass a popular tonic for treating debility of convalescence when taken as a juice. Oat grass is also extremely rich in antioxidants, including polyphenols and one powerful antioxidant called tricin. Current research on oats focuses on the compound, beta-glucan, that has been shown to stimulate immune functions.
