Thujone
Northland Laboratories now offers confidential Thujone analysis using TTB methods.
Thujone – pronounced "thoo-jone" with a soft 'J' – is a naturally occurring substance. Thujone is a monoterpenoid ketone consisting of two isomers, alpha and beta, that exist in varying ratios in different plants species. Plants such as cedar leaf, sage, tansy, thyme, rosemary and wormwood (an ingredient found in certain flavored distilled spirits such as absinthe) are known to contain thujone.
It is widely reported that thujone is "banned" as a food additive by the Food and Drug Administration (FDA), but thujone is not itself specifically regulated by the FDA. Thujone is only regulated in the context of five herbs, which are approved as food additives when the finished product is essentially "thujone free". These approved herbs are: Artemisia spp. (wormwood), Thuja occidentalis (white cedar), Evernia prunastri (oak moss), Tanacetum vulgare (tansy), and Achillea millefolium (yarrow).
The Alcohol and Tobacco Tax and Trade Bureau (TTB), which has regulated alcohol-containing products in the United States since 2002, says on its website that natural flavorings used in alcoholic beverages must comply with FDA regulations. Using wormwood as the example, it states that finished products must be thujone free.
What does ‘Thujone-Free’ mean?

The term 'thujone free' means less than the limit of detection of the specified method which is, in this case, 10 ppm.
“We approve the use of the term "absinthe" on the label of a distilled spirits product and in related advertisements only if the product is "thujone-free" pursuant to the Food and Drug Administration's (FDA) regulation at 21 CFR 172.510. Based upon the level of detection of FDA's prescribed method for testing for the presence of thujone, TTB considers a product to be "thujone-free" if it contains less than 10 parts per million of thujone. However, should the FDA set a new standard for “thujone-free,” in accordance with 27 CFR 13.51, COLAs that are not in compliance with that revised standard will be revoked by operation of regulation.”
TTB will approve Certificates of Label Approval (COLA) for products that contain thujone if they contain less than 10 ppm of thujone". The TTB's regulatory interpretation has allowed at least four wormwood-containing absinthes to gain approval for sale in the United States.
