Avena Sativa, more commonly known as oats or wild oats, is an annual grass which is cultivated for its edible grain. It grows up to 4 feet tall with pale green, narrow, flat leaves. The grooved grain is somewhat hairy and narrow with almost parallel sides. The parts that are typically used are the seeds and stems. Avena Sativa seeds are not only a rich source of carbohydrate and soluble fiber; they also have the highest content of iron, zinc, manganese, calcium and vitamins A, B and E of any other grain.
