Oatstraw is the green top of the oat plant, harvested when the seed is at the milky stage, before it's fully ripe. The herb is nutritive and soothing to itchy, flaky skin and is used in baths, lotions and skin washes. It also makes a comforting herbal tea. Cultivated for over 3,000 years, oats were not an intentionally cultivated grain. A happy accident, it was orginally considered a weed among other crop grains. However, its tenacious nature and and wide tolerance for growing conditions led to eventual appreciation. It can thrive through stretches of poor growing conditions while other crops struggle.
