This essential oil is steam distilled from the flowering herb of Tanacetum Vulgare. The plant is a very common wild growing perennial, probably originating in Central Europe and brought to the United States by the European immigrants. Tansy Oil is a yellowish to orange olive liquid with a warm, almost sharp and spicy, dry and herbaceous odor. The taste is very sharp, pungent and bitter. This oil is toxic due to the high content of Thujone. It should not be used in flavors or any food preparations.
