The Science Behind Aromatherapy
Aromatherapy isn't just about pleasant scents — it's a practice backed by growing scientific evidence. When you inhale essential oil molecules, they interact with olfactory receptors that send signals directly to the limbic system, the brain region responsible for emotions, memory, and certain physiological functions.
How Aromatherapy Works
Inhalation Pathway
Aromatic molecules travel through the nasal cavity to olfactory neurons, which transmit signals to the amygdala and hippocampus. This direct neural pathway explains why certain scents can instantly trigger emotional responses or memories.
Absorption Pathway
When applied topically, essential oil compounds penetrate the skin and enter the bloodstream. Studies using blood analysis have confirmed that compounds like linalool (from lavender) can be detected in the blood within 20 minutes of topical application.
