Sage oil has a sharp, herbal smell, and is watery in viscosity.
It is an evergreen perennial herb that can grow up to about 60cm ( 2 feet) high with a woody base, soft gray-green oval leaves and a mass of blue or violet flowers. The Chinese believed that it cured sterility, while the Romans believed it cured just about everything.
The name is derived from the Latin word 'salvare' which means 'heal' or 'save' and during the Middle Ages it was a popular ingredient of many nerve tonics and the herb was also used to clean gums.
