Cedarwood
The use of cedarwood essential oil dates back thousands of years, so it is believed to have been one of the first oils to be distilled in human history.
There is much evidence that this oil was used by ancient civilizations for its antiseptic and sedative properties among others.
The first reference to its use was in 1800 BC. from the Sumerians. They used cedarwood essential oils in various applications, such as as a base for the paints they used to decorate their pots.
The ancient Egyptians also used it in embalming ceremonies like other oils, e.g. thyme.
The essential oil came mainly from the Lebanese cedar, the national emblem of that country which is also present in its current flag.
