Essential oils are great for helping physically and expanding spiritually. Essential oils are also beneficial emotionally. Oils affect the brain two ways: via olfaction and via essential oil absorption. Essential oils are therapeutic due to the known chemical components. They are also likely working in tandem with other factors.
When a fragrance is inhaled, the scent of an essential oil impacts the brain through the olfactory system. The odor molecules travel up the nose and are trapped by olfactory membranes. These membranes contain approximately 800 million nerve endings, which receive the micro-fine, vaporized oil particles. They are carried along the axon of the nerve fibers and connected with the secondary neurons in the olfactory bulb in the brain. The olfactory bulb then transmits the impulses to the limbic system, which is directly connected to areas of the brain that control heart rate, blood pressure, breathing, memory, stress levels, and hormone balance.
Essential oils have emotional benefits. They work because essential oils and human beings have a lot in common. As Valerie Ann Worwood (author of The Fragrant Mind) says, both are alive—“chemically, electrically, and in terms of infrared radiation” (Worwood, 11). Frequency, a measurable rate of electrical energy that is constant between any two points, is within every living being, according to Robert O. Becker, M.D., who wrote The Body Electric. In his research, he discovered that lower range essential oils actually create physical change in the body, and high frequency oils create spiritual/emotional changes. So the application of a high frequency or vibrational substance, alters our physical, emotional and spiritual vibration or frequency. This can alter our mood and make us feel good.*
