What is Oats?
Oats are hardy annual grasses able to withstand poor soil conditions and are best adapted to areas with a cool, moist climate. Russia, the US, Finland, and Poland are the world's major oat-producing countries. The plant grows to about 61 to 91 cm in height with straight, hollow, blade-like leaves. The flowers, which contain 2 or 3 florets, are clustered at the top of the plant. Oat grain grows enclosed in 2 hulls that protect it during development. It contains 3 main structures: the bran, endosperm, and the germ.

What is it used for?
Derived from wild grasses, the oat was domesticated into today's cultivated plant. The oldest known oat grains were found in Egyptian remains from about 2000 BC. Scottish settlers introduced oats into North America in the early 17th century. Before being used as a food for humans, oats were used as a livestock feed in the form of grain, pasture, hay, or silage. Traditional medicinal uses of oats include the treatment of rheumatism, depression, chronic nerve pain, and loss of bladder control, and, externally, as a skin cleanser and softener.
