Oatstraw

Avena sativa

Medicinal herbsKitchenHarvest

The same plant as breakfast — milky tops and straw as a traditional nervine food-tea.

Oat is a cool-season cereal. The grain is porridge. Herbalists also cut the green, milky tops (and later the straw) as a gentle mineral nervine. This is food-adjacent, not a hypnotic. People with celiac disease need certified oats; the plant itself has no gluten but the mill often does.

Flavor

Green hay, milk, a little sweetness. Straw tea is quieter than the grain.
