Similar to our own immune system, plants draw upon this vital force to protect and sustain their life. Effects of Aromas and The Limbic System Essential oils are a potent form of the plants healing power. One drop of essential oil can have as much medicinal quality as over an ounce of the dry herb. The oils are most effective used externally and are not recommended for internal use. For inhalation, simply put a drop or two on a cloth and hold under the nose.
Inhalation energizes the olfactory nerves which in turn stimulates the limbic system.
The limbic system is the seat of emotions and memory. This is why aromas are often described by what they remind us of. Through the limbic system, aromas affect the hypothalamus and pituitary gland helping to regulate bodily functions and the chemical balance within the body. Essential oils are also able to penetrate the skin and nourish the blood stream and other parts of the body more directly than simple inhalation. This is exciting for body workers.
