Anxiety is more than just worry — it’s a chronic state that can affect your mental, emotional, and physical health.

This guide explores 20 scientifically-supported essential oils, how they work, how to use them safely, and what experts say.

🌱 How Do Essential Oils Help with Anxiety?

Essential oils interact with the olfactory system, triggering the limbic brain — the center of emotions. This can influence mood, heart rate, stress hormones, and neurotransmitter balance.

Mechanisms include:

• Modulating cortisol levels
