Oat Straw Green Tops

(Avena sativa)

Long before the oat became a breakfast staple, its green, unripened straw was prized by herbalists across Europe as a restorative tonic for the nervous system and a nourishing source of vital minerals. Avena sativa — the common oat — is a cereal grass of the family Poaceae, cultivated for millennia across temperate regions of Europe, Asia, and the Americas. Oat straw refers specifically to the green aerial parts of the plant harvested before the grain fully matures, when the stalks and leaves are at their peak nutritional and phytochemical richness. In traditional European herbalism, oat straw was a foundational remedy for nervous exhaustion, debility, and convalescence — valued as much for its gentle, food-like safety as for its deeply nourishing character.

The herb is rich in a broad spectrum of constituents including silica (one of the highest plant sources), calcium, magnesium, iron, phosphorus, potassium, B vitamins (including B1, B2, B3, and B6), flavonoids (including vitexin and isovitexin), saponins (avenacosides), alkaloids (including avenine), steroidal compounds, polyphenols, and chlorophyll. Available in Cut & Sifted and Powder forms.
