Oat Straw/Green Oats

Green oats (Avena Sativa) is an herb native to northern Europe, now grown worldwide as a cereal crop. The young green parts of the oat plant, also known as oat straws, are harvested in late summer. Oat straw contains triterpenoid saponins of the furostanol type (avenacosides) with fungicidal activity.1
