Essential oils have been used for centuries in traditional wellness practices, yet modern science is only beginning to understand how and why they influence our senses, emotions, and daily well-being.
In this article, we explore how essential oils work, combining scientific insight with holistic understanding, and explain why aromatherapy continues to be widely used as a complementary wellness practice.
Essential oils are made up of volatile aromatic compounds naturally produced by plants. These compounds are responsible for the plant’s scent and play a role in its interaction with the environment.
When extracted—most commonly through steam distillation or cold pressing—these compounds become highly concentrated, which is why essential oils are used in very small amounts.
Each essential oil has a unique chemical profile, which explains why different oils have different aromas and traditional uses.
