Whether it is occasional memory loss, lack of focus due to, too having to multi-task or general brain fog, essential oils could be the natural way to clear your head and gain clarity of thought.

Essential oils are the pure oils that are extracted from flowers, plants, herbs, fruit or even the bark and resins from trees. These pure oils all have their own unique chemical complex, and therefore have a variety of therapeutic actions, that can help clear the mind, aid concentration, give clarity of thought and allow us to focus.

When using essential oils to improve memory & concentration, it is mainly the aromas of the oils that have the effect. As we inhale the fragrance, the ‘smell sensing cells’ connect to the nerves which then send messages to the brain, to have an effect – in this case, clearing and stimulating the nerve pathways to allow for better reception and transmission of messages.
