Have you ever noticed some scents are more positively associated in your minds than others? Our sense of smell is one of our most powerful senses. Our body contains over 1,000 receptors for smell—more receptors than for any other sense. Essential oils stimulate the limbic system – the part of the brain involved in memory, mood, motivation, and behaviour. By putting essential oils directly into the air we breathe, we can influence the feeling of our environment, and, more powerfully, our own emotions.
