Common Name Standardized: barleyOther: yava Botanical Name Hordeum vulgare L.Plant Family: Poaceae Overview IntroductionBarley grass has been used in traditional Chinese medicine for at least 1800 years. Barley grass is grown by soaking the seeds in clean water until they sprout and grow shoots approximately 2 inches (5 cm) long.ConstituentsBarley grass is an extraordinarily rich source of many vitamins, minerals, and amino acids, although it does not, as sometimes claimed, contain absolutely all the nutrients needed for human health.The dried shoot is approximately 4% glutamic acid (needed for recharging antioxidants), 4% methionine (needed for the production of natural SAM-e), 3% vitamin C, 1% valine, and 1% calcium. A single tablespoon contains a day's supply of beta-carotene, betaine, biotin, boron, copper, iron, lutein, magnesium, niacin, riboflavin, and thiamine. It also contains nutritionally significant amounts of alpha-linoleic acid, oryzanol, potassium, selenium, zinc, and the tocopherols that make up vitamin E.The medicinal action of the dried shoot is due to its content of hordenine, not to be confused with a plant chemical with a similar name that is implicated in celiac disease.Parts UsedThe dried unjointed leaf. In traditional Chinese medicine, the barley grass may be "massed" or fermented before drying.Typical PreparationsA level tablespoon (3-4 grams) of barley grass powder added to teas, smoothies, cereals, or other foods daily. As a capsule or in extract form.
