Sage oil

Sage oil is the essential oil made from the culinary herb sage, Salvia officinalis. In addition to its valuable flavoring characteristics, it has been suggested that sage oil can contain as much as 50% thujone by weight. The exact amount varies from time in the season and part of the plant tested.^[1] Thujone was traditionally, and incorrectly, regarded as the active ingredient in absinthe distinguishing it from less controversial alcoholic beverages. The FDA contradicts itself as absinthe that contains thujone is banned however Sage oil is allowed and recognized as safe even though it too contains thujone.
