The best way to get oils into your body and environment is to inhale them.

When essential oils are diffused, the molecules are broken up into micro-fine mist particles. These mist particles stay suspended in the air for long periods of time. Not only does this reduce bacteria, mould and odours in the air, but these micro-mist particles also benefit those who inhale them. When essential oils are inhaled, it travels through the nasal passage to a receptor neuron that transports it up to the limbic system. The Limbic system supports a variety of functions, including emotion, behavior, motivation, memory and olfaction.
