Oats is one of the best remedies for ‘feeding’ the nervous system, especially when under stress. It is specific in cases of nervous debility and exhaustion, especially when associated with depression. It may be used with most of the other nervines, both relaxant and stimulatory, to strengthen the whole of the nervous system. It is also used in general debility. The high levels of silicic acid in the straw will explain its use as a remedy for skin conditions, especially in external applications.   (9)

General Notes:   The traditional staple of Northern Europe, oats are a warm, sweet food, ideal in a cold climate. Cereal made from oatmeal (the crushed grain) is a nutritious breakfast. For medicinal purposes the whole plant (known as oatstraw) is generally used and is gathered when the grains are ripe. The herb is a good restorative tonic, ideal for depression and qi (energy) deficiency.  Recent research has shown that oat bran, and to a lesser extent oatmeal, can help to reduce abnormally high blood cholesterol levels.

“…taking oats is a complete body overhaul from the inside to the outside.” 

Peter Holmes, 1989.

          Dr. Bach recommended his Wild Oats flower remedy for times of uncertainty and dissatisfaction.   (15)
