A Beginner’s Guide to Aromatherapy: Benefits, Uses, and Safety Precautions of Essential Oils

Aromatherapy is a holistic healing treatment that uses natural plant extracts to promote health and well-being. These plant extracts, also known as essential oils, are used for their therapeutic properties and can be inhaled, applied to the skin, or added to a warm bath.

In this article, we’ll explore the benefits and uses of aromatherapy, as well as some common questions and concerns about the practice.

How Does Aromatherapy Work?

Aromatherapy works by stimulating the olfactory system, which is responsible for our sense of smell. When we inhale essential oils, the molecules enter our nasal cavity and stimulate the olfactory nerves, which send signals to the brain’s limbic system. This area of the brain is responsible for regulating emotions, memories, and other functions related to our sense of well-being.

In addition to the olfactory system, essential oils can also be absorbed through the skin and into the bloodstream. When applied topically, essential oils can have a range of therapeutic effects on the body, depending on the oil’s properties.
