Oatseed
The common oat used in herbal supplements and foods is derived from cultivated sources. For some herbal supplements, the green or rapidly dried aerial parts of the plant are harvested just before reaching full flower. Many herbal texts refer to using the fruits (seeds) or green tops.
In folk medicine, oats are used by herbalists to treat nervous exhaustion, insomnia, and “weakness of the nerves.” A tea made from oats was thought by herbalists to be useful in rheumatic conditions and to treat water retention. A tincture of the green tops of oats was also used to help with withdrawal from tobacco addiction. Oats were often used in baths to treat insomnia and anxiety as well as a variety of skin conditions, including burns and eczema.
The fruits (seeds) contain alkaloids, such as gramine and avenine, and saponins, such as avenacosides A and B. The seeds are also rich in iron, manganese, and zinc.
Usually 1-4 grams of oatseed are recommended daily for insomnia.
