Aromatherapy can be achieved in two ways, (1) Inhalation and (2) Topical Application.
Inhalation:
When you inhale a natural plant extract, the scent is carried by olfactory nerve cells in the nose to the olfactory system. This, sends the aroma to the brain, the limbic system, which houses your emotions and emotional behaviour. Depending on the oil, you may begin to feel more relaxed and calm or alert and aware.
Topical Application:
Plant based extracts or oils have high antioxidant properties. When these oils are applied to the skin, they are absorbed and attach to body fat and fluids. Since oils don’t dissolve in water it attaches to our body fat bringing their antioxidants through the immune system.
