There's a reason oat straw has been an acknowledged source of food for hundreds of years. Oat straw is a nourishing, nutritive by-product derived from the stalk and leaves of the Avena sativa plant. Many herbalists believe oat straw is an energy booster, possibly because it's so well known for its bountiful vitamin and mineral content. Long considered a great health tonic, traditional health practitioners also utilized this surprisingly versatile ancient grain for tonics, tinctures and teas. Now you can get the nutrient-dense oat straw delivered in a more modern way. Reap the whole plant power of oats in our Full Spectrum Oat Straw capsules.
