''On a physical level, because essential oils are made up of very small molecules, they are able to penetrate into our blood stream and can help many problems. They are used extensively in the spa industry to help ease muscular aches and pains, improve circulation and ease sinus congestion. In skincare products, by penetrating into the deeper layers of the skin, essential oils can have a positive effect on the skin, such as optimising the cellular renewal process, enhancing blood circulation and addressing problems such as acne, eczema and ageing skin.

On an emotional level, the aromas of essential oils can have a dynamic effect. The sense of smell is the most primitive of our senses, and is linked to the deepest parts of the brain which govern basic instincts, memories and emotions."
