History: |
Oats are one of the many plants that straddle the fine line between "herb" and "food". They have been a staple human and animal crop, worldwide, since prehistoric times. For centuries—before vitamin and mineral supplements arrived on the scene to fill in the gaps created by poor nutrition and stress—old-time herbalists, midwives, and rural doctors relied heavily on oats for their superb nourishing and restorative powers. Oats were the first choice for strengthening the body after childbirth, a long bout with illness, or simple nervous exhaustion. In fact, the plant's Latin name, avena, means "nourishing". While the term "oats" and "oat straw" are often used interchangeably (as they are here), technically "oats" are the husked oat seeds, and "oat straw" is the whole plant, harvested when the seeds are ripe. And it is the whole plant that delivers the biggest medicinal bang. |

To lower cholesterol and treat gout, rheumatism, skin diseases, insomnia, and symptoms of old age. Oats have antidepressant, antispasmodic, demulcent, nutritive, and stimulating properties, as well as a general calming effect on the nervous system. Avenine, one of oats' principal chemical ingredients, is responsible for the herb's sedating action. As a source of nutrition, oats have few herbal rivals. They are rich in glycosides, iron, manganese, phosphorus, potassium, proteins, vitamins E and K, the B vitamins, and zinc. As a restorative tonic oats targets the bones, endocrine system, heart, intestines, nervous system, tissues, and thymus gland. The whole plant—in cereal/grain form or in decoctions—is prescribed internally for general debilitation, stress, exhaustion, depression, estrogen deficiencies, gastritis, high cholesterol, and impaired immune function. Externally, oats are used in baths and facial masks to soothe and heal dry skin, skin rashes, eczema, and poison ivy. |
