Many natural health enthusiasts are well aware of the benefits of oats and oatmeal. Oats help reduce blood cholesterol levels, remove body fat, and provide an excellent source of healthy carbohydrates. Many people have at least heard of the word “avena” in connection with oatmeal baths and facial masks. However, not as many people are aware of the healing properties contained in oat straw. Calcium-rich oat straw (avena sativa), is the green oat grass and tops in the “milky” stage before the mature oat grains form a head. Many resources in the alternative health literature promote oat straw for osteoporosis and osteopenia. Oat straw is also promoted as being a nervine herb, which can be used as a remedy for anxiety. The herb has been recently proven to aid in cognitive performance in the brain. Oat straw may be most widely promoted as a sexual performance enhancer for men when used alone, and as a sexual stimulant for women when used in combination with either saw palmetto or stinging nettle. However, no peer-respected research has been done to support these claims.
