What are essential oils?

Essential oils are natural compounds that are extracted from plants. These compounds have the scent, flavor, properties, and essence of the plant.

Each essential oil gets its unique characteristics from its aromatic compounds. Essential oils are derived through the process of distillation or cold pressing. 

After extracting the aromatic chemicals, these are mixed with a carrier oil to create the essential oil.

Extracting essential oil is of utmost importance, as the oils extracted through chemical processes are not true essential oils.

How do essential oils work?

There is a lot of confusion in the minds of people in regard to “how do essential oils work?” 

Essential oils are commonly used in aromatherapy, to be inhaled via various methods, but are not meant to be swallowed. 

The chemicals present in the essential oils interact with our bodies in numerous ways. When we inhale the aroma of essential oils, it stimulates the limbic system, a part of the brain that is responsible for a sense of smell, emotions, behaviors, and long-term memory.

The limbic system also controls several unconscious physiological functions like heart rate, breathing, and blood pressure. Essential oils can also exert a physical effect on the body.
