Benefits of Aromatherapy

Aromatherapy BenefitsEssential oils from plants have been used for thousands for years for therapeutic purposes. This practice is popularly known as aromatherapy because the highly concentrated essential oils emit scents that are believed to have healing powers. Although these aromatic scents are mostly inhaled, the oils are also used to massage the body, which increase their healing effects. Because of these health benefits, aromatherapy is now being used as part of complementary and alternative medicine to treat stress, infection, chronic pain, and other health problems.

How Aromatherapy Works

Aromatherapy uses concentrated essential oils extracted from various plant roots, seeds, leaves, and flowers. These emit aromatic scents that may be directly inhaled, although the oils may also be applied to the skin in the form of lotions, bath salts or massage oils. The strong aroma is believed to stimulate the receptors in the nose, which send signals to the part of the brain that controls your emotions. Some scientists believe that scents can stimulate the activity of certain brain cells in a way that is similar to the way some medications work. Others think that essential oil molecules may interact with enzymes or hormones in the blood. When used for massage, essential oils are absorbed by the skin and at the same time, manipulation serves as physical therapy.

Aromatherapy is widely used in a variety of settings. It is popularly used in health spas, but hospitals, clinics and even homes use it to treat a variety of conditions, including  pain, anxiety, and depression. Some examples of essential oils that have been shown to be effective in relieving stress, anxiety, and depression include lavender, rose, bergamot, lemon, orange, and sandalwood. For people who have chronic health conditions, aromatherapy is believed to improve the quality of life.

Aromatherapy is a safe and effective form of complementary and alternative medicine that may be used in combination with conventional medical therapies. When used as directed, essential oils may be safely used to reduce symptoms of many health conditions. However, they are not FDA-regulated and more studies are needed to prove their effectiveness in treating diseases. Applying essential oils to the skin may trigger allergic reactions or skin irritation. They may also interact with your medications. Breast feeding and pregnant women must ask their physicians if they may use aromatherapy.

Consult your doctor and look for a trained aromatherapist when considering the use of aromatherapy.
