Essential Oils: Benefits, Uses, and Scientific Evidence for Health & Wellness

Introduction: What Are Essential Oils?

Essential oils are highly concentrated plant extracts obtained from flowers, leaves, bark, roots, seeds, and resins. They capture the plant’s aroma and bioactive compounds, which are responsible for their therapeutic properties. Used for centuries in traditional medicine, essential oils are now gaining renewed scientific interest for their potential role in physical, mental, and emotional well-being.

From lavender and peppermint to frankincense and tea tree, essential oils have become a cornerstone of modern integrative and complementary health practices.

How Essential Oils Work in the Body

Essential oils influence the body through three main pathways:

1. Inhalation (Aromatherapy)

Volatile compounds travel through the nose to the olfactory system, directly affecting the limbic system—an area of the brain involved in:

• Emotions

• Memory

• Stress response

• Hormonal balance

2. Topical Absorption

When diluted and applied to the skin, essential oils penetrate the epidermis and enter systemic circulation, where they may:

• Reduce inflammation

• Relieve pain

• Support skin health

3. Psychological and Neurological Effects

Certain compounds interact with neurotransmitters such as GABA, serotonin, and dopamine, influencing mood, sleep, and anxiety levels.
