He was a healer as well an architect, mathematician, scribe, astronomer and Grand Vizier to King Djoser. He was later deified and worshiped as the god of healing. He deserves recognition as being the father of Aromatherapy. Ancient Egyptians also delighted in burning incense which is another form of Aromatherapy. Burning Kyphi, an aromatic formula recognized as one of the oldest perfumes, was said to lull to sleep, allay anxieties and brighten dreams with those things that delight most in the night.
Aromatherapy is our physical reaction to essential oils when they enter our body.
The first step in understanding Aromatherapy is to understand the difference between it and the psychology of fragrance , which is our emotional reaction to scent. When molecules of scent enter the nasal passages, receptors in the nose are triggered. Here the scent is interpreted and a signal for appropriate action is immediately sent to the consciousness. This is the emotional reaction to the scent. For instance, the odor of gas might signal danger or fear.
