Have you ever wondered what an emotion actually is?

Where are those feelings that can pop up and fluctuate out of nowhere stored in the brain? How on earth could an aromatic plant essence improve something like our emotional center? How could something we smell support our body and organ health? We took a deeper look at the science and found some pretty cool facts.


When we inhale through our nose, airborne molecules interact with the olfactory, organs and, almost immediately, the brain.

Molecules inhaled through the olfactory or mouth are also carried into the lungs where they interact with the respiratory system and from there, can also travel into the blood stream. Thus, inhaled essential oils can positively affect the body through several systems pathways.

Many substances are prohibited from entering the brain by a highly selective semipermeable membrane barrier called the Blood-Brain BarrierEach essential oil consists of dozens to sometimes hundreds of organic constituents, all of which, are primarily composed of Carbon, Hydrogen and Oxygen. The molecules of essential oils are all very tiny and most can pass through the Blood Brain Barrier, where they then enter the brain and limbic system! Limb what?

Essential oils and the brain Aroma and the brain young living and mood


The limbic system is commonly referred to as the “emotional brain.” This is the oldest area of the brain.

The limbic system is directly connected to those parts of the brain that control a large array of things like heart rate, blood pressure, breathing, memory, motivation, stress levels, hormone balance (endocrine system), hunger, learning and basic emotions such as fear, pleasure response and anger.

This relationship between aromatic molecules and the limbic system explain why smells can instantly trigger emotions. New scientific evidence shows that inhaling pure, living essential oils may be one of the fastest ways to create physiological or psychological benefits. Some of these benefits include decreasing anxiety, anger & fatigue, hormone & appetite balance,  mood enhancement and sleep regulation.



These naturally occurring organic compounds in essential oils also provide support for every system of the body: the skeletal system, muscular system, circulatory system, endocrine system & hormones, respiratory system and immune system.

Tests have shown that oils reach the heart, liver and thyroid in three seconds when inhaled and they were found in the blood stream in 26 seconds when applied topically.

Many oils are used to promote the body’s own physical healing — such as inflammation response, fighting off infections, cell function and organ support. Young Living’s Essential Oils are a beautiful way to start supporting your entire body everyday!
