In studies performed at Vienna and Berlin Universities, researchers discovered that sesquiterpenes, a natural compound found in essential oils of Vetiver, Patchouli, Cedarwood, Rosemary, Sandalwood and Frankincense Rivae, Frankinense Sacra can increase levels of oxygen in the brain by up to 28 percent (Nasel, 1992).
Such an increase in brain oxygen may lead to a heightened level of activity in the hypothalamus and limbic systems of the brain, which can have dramatic effects on not only emotions but on learning, attitude, and many physical processes of the body such as: immune function, hormone balance, and energy levels. High levels of sesquiterpenes also occur in Melissa, Myrrh, Cedarwood, and Clove essential oils.
Research from the universities of Berlin and Vienna found that sesquiterpenes increase oxygenation around the pineal and pituitary glands. This allows for ideal balance of emotion-regulating and memory-stimulating hormones. We recommend brain blends such as Brain Health, Stress Ease Now, and Mind Over Matter, to calm your emotion, create more oxygen, ease headaches, ease stress, to build your immune system and quiet all over body inflammation.
The bottom line is that essential oils can penetrate not only the blood-brain barrier, but they can also penetrate the skin, follow nerve pathways, follow the meridians, and provide healing and balance even at the cellular level such as cellular memory and DNA.
