Oat Straw: A Tonic for the Nerves

We're continuing our botanical journey today with one of the key herbs featured in our Sleepy Time Tea -  Oat straw. Oat straw consists of the green, unripe leaves and stems from oat grass. If the plant is left to mature, the oat tops eventually develop into kernels, or oat groats, that we know and love as cereal grain. Sure, they may not be as beautiful as the mighty rose or calming chamomile we recently wrote blog articles on, but that doesn't make them any less impressive, medicinally speaking. So let's dive into it!

The History of Oat Straw: Oats have been around for centuries and have been consumed both as a whole plant food and in medicinal preparations. Porridges and gruels count amongst the first recorded meals and have been based around the stripping and cooking of the oat plant. 

Indigenous peoples often used oats for the base of meals to increase the vitality and stamina of those consuming them regularity. Oats were also used to remedy mental and physical exhaustion, insomnia, digestive issues and to help regulate blood sugar levels. 

Medicinal Uses: Oats make a fantastic “tonic” for the nervous system by strengthening and nourishing nerves that have been heavily depleted from stress. Oats are a wonderful ally for those who suffer from mental or physical exhaustion, especially when associated with depression. 

Research shows that oat straw is a supportive tool in tobacco and alcohol cessation, breaking unhealthy habits, and can assist in convalescence. (Source)  It can help to support shingles, herpes, multiple sclerosis, and to strengthen an overall weakened constitution.

Topically it is used to support a variety of skin irritations, itching from bug bites, blisters, and inflammation. There is also evidence to support the use of oat straw for impotence and sexual dysfunction, including vaginal dryness and pain during intercourse. Oat can contribute to the health of the reproductive system by releasing luteinizing hormone from the brain. (Source)

Food Uses: Oatmeal porridge or gruel is a popular cereal made from the grain, while oat straw can be used to infuse tea that soothes the nervous system, stabilizes blood sugar and nourishes the body.

Cosmetic Uses: Colloidal oats, which is simply oat flour produced by grinding oat kernels, is a very popular additive in skincare formulations for rashes, dry, sensitive, inflamed, itchy, or damaged skin.

Oats are emollient in nature, meaning that they can soften and soothe the skin. Adding colloidal oats to a bath produces milky water that gently cleanses while also moisturizing and protecting the skin. Adding oat flour to a warm bath will soothe rashes, itchy, or inflamed skin. Colloidal oats can also be added to face masks or body wraps for the same effects. 

In skin care products, oat straw acts as a calming agent due to its soothing properties and rich silica content, making it perfect for sensitive skin formulations. Oat straw can also be used in shampoos and hair conditioners to import softness and shine to your hair and soothe itchy scalps. (Source)
