Native to Eurasia and widely cultivated around the world, oats are best known as a food crop, but the milky tops and straw also have a long history of use in herbal practice. The aerial parts are most often used in infusions, while the milky seed tops are sometimes prepared separately. In Western herbal traditions, oatstraw is regarded as a nourishing herb commonly used in long infusions, baths, and gentle nervine blends. It is often chosen for its mild character and mineral-rich profile rather than for a strong bitter or aromatic effect.
