What are Essential oils and how do they work?
What are essential oils?
Essential oils are concentrated plant extracts that retain the natural smell and essence. The essential oils are extracted from plants via distillation or mechanical methods such as cold pressing. Once the aromatic chemicals have been extracted, they are combined with a carrier oil. Carrier oils are used to dilute the essential oils, the reason they are used to dilute these oils is because the essential oils are very potent and in their pure form would be too strong for enclosed environments.
How do essential oils work?
Essential oils are most commonly used in the practice of aromatherapy, in which they are inhaled (most commonly via a mist created from a humidifier). Inhaling the aromas from essential oils can stimulate areas of your limbic system, which is an area of your brain that plays a role in emotions, behaviours, sense of smell, and long-term memory. The limbic system also plays a role in controlling several unconscious physiological functions, such as breathing, heart rate, and blood pressure.
