How does Aromatherapy Work?
The human sense of smell has evolved since the time of the hunter-gathers, but the physical mechanism is unchanged. The sense of smell is 10,000 times more sensitive than using any other of our senses.
Smell is the only sense
directly connected to the limbic
system, situated on top of the midbrain(brain stem). The limbic system is the center of the sensory experience, processing memory, creativity, learning, emotions, pleasure, sex drive, hormones and rhythmic processes such as heart rate, body temperature, breathing. Impulses from olfactory nerves bypass the
neo-cortex and go directly to the
limbic system. Through this direct connection you react first, you don't think, when you smell something.
