Oatstraw
Avena sativa
Oatstraw comes from the same plant that gives us oats, but when harvested in its milky stage or as a dried green stem, it becomes a deeply nourishing, mineral-rich herb. It’s especially beloved for calming the nervous system, strengthening the adrenals, and offering gentle yet powerful support for anyone feeling depleted or overwhelmed. This is a “hug in a mug” kind of herb, comforting and safe for daily use.
You might need oatstraw if . . .
- You’re feeling frazzled, worn out, or emotionally on edge.
- You struggle with sleep or tension headaches from stress.
- You’re postpartum, breastfeeding or just feeling like your cup is empty.
