Aromatherapy

Aromatherapy is used alongside of health and wellness treatments and can be used for insomnia, anxiety, pain and itching. Chemical compounds in some essential oils have been shown to have anti-fungal and antimicrobial properties. Emotions and memories are  linked to the olfactory system. This system’s primary processing pathway involves the limbic system and the amygdala is the only sensory system that involves the amygdala. This link allows an understanding of fragrance and memory. For example, many people associate the smell of cinnamon with cookies or a cake baking in the oven. This pleasant smell recalls a sense of home or sharing a meal with people. Generally speaking, aromatherapy is thought to promote changes in mood and in relaxation in individuals. 
Many medical professionals believe the inhalation of essential oils can communicate signals to the olfactory system and stimulate the brain to exert neurotransmitters (e.g. serotonin and dopamine) thereby further regulating mood.
