It is believed that aromatherapy works on the limbic system of your brain. It's interesting to find out exactly how simple aromas can affect our bodies to remedy so many different things.
Inhalation is the most popular method and gives the most rapid effect. The molecules of essential oils are inhaled through the nose, and the molecules interact with the top of your nasal cavity. Those molecules are transmitted to the limbic system of the brain. The limbic system is connected to the part of the brain that controls blood pressure, breathing, heart rate, stress level and hormonal balance. This is how oils have such a great effect on your moods and stress levels.
The topical method is when oils are applied to the skin through a compress or directly on the skin. The oils are absorbed quickly through the skin into the blood stream. They penetrate the skin through the tiny hair follicles and sweat glands into the bodily fluids where it is believed they help to kill viruses and bacteria in the body. They also help to strengthen the immune system which helps to fight off any future attacks of the body.
Certain oils increase circulation and eliminate toxins from the body. Some oils promote new cell growth and encourage the body to heal itself. Different oils will have different effects on the body.
Before applying oils to the skin or ingesting them, it is important that you speak to your physician. Some oils are highly toxic, could cause allergic reactions, or could have interactions with other medications.
