If we follow essential oil records back through time, we arrive as far back as the time of the Ancient Egyptians. A scroll discovered by archaeologists dating back to around 1500 BCE was deciphered and found to list hundreds of remedies employing the use of essential oils.
Fast forward to the turn of the millennium, and we find the Bible describing essential oils in a number of instances, most notably when baby Jesus was given frankincense and myrrh. Then, there were the Ancient Greeks and Romans, who would diffuse essential oils inside their homes, public buildings and steam baths to maintain good health and keep things smelling beautiful.
