Aromatherapy typically works in two different ways; through inhalation or topical application. 

Inhalation works by inhaling a scent through your nose, allowing for molecules from the essential oils to bind to olfactory cells. This causes your olfactory receptors to send signals to your brain (Limbic System), stimulate the amygdala (emotional processing) and hippocampus (memories), and as a result can trigger psychological and physical reactions such as boosted mood, sedation or relaxtion, increased focus, etc.

Topical Application works by applying a a single essential oil or a blend to your skin, which gets directly absorbed into the bloodstream. Topical application oftentimes can provide a more invigorating physical response for ailments such as headaches or muscle tension, but also provides aromatic benefit as well.
