Yarrow, Oil (achillea Millefolium L.)

Yarrow oil (Achillea millefolium L., CAS Number 8022-07-9) is a volatile essential oil extracted from the above-ground flowering portions of the yarrow plant, a common herbaceous perennial native to Europe and temperate Asia. The oil is obtained through steam distillation or solvent extraction and contains various volatile compounds including alpha-pinene, beta-pinene, sabinene, myrcene, and 1,8-cineole, which contribute to its characteristic aromatic and flavor profile.

Yarrow oil functions as a flavoring agent or flavoring adjuvant in the food industry, primarily in beverage formulations, culinary preparations, and traditional herbal products. It is used in small quantities to impart herbal, slightly bitter, and peppery notes to various food and drink applications. The oil has been traditionally employed in European folk cuisine and in the production of certain liqueurs and bitters. Due to its potency, only minute amounts are required for flavoring purposes.

Yarrow oil has generated no adverse event reports with the FDA and no product recalls associated with its use as a food additive. The oil contains compounds that have been studied in various contexts, though comprehensive toxicology data specific to food-use levels remains limited. Some volatile components in yarrow oil, particularly thujone (found in variable concentrations depending on the plant source and extraction method), have historically raised regulatory questions in other herbal products, though typical food-use levels of yarrow oil are generally considered minimal-risk.

When used as a flavoring agent in appropriate quantities, yarrow oil is typically considered safe by users and regulatory bodies. However, it should be distinguished from medicinal or therapeutic uses of yarrow preparations, which operate under different safety considerations. The concentration and exposure levels through food flavoring applications are substantially different from therapeutic herbal use.

Yarrow oil has not received FDA GRAS (Generally Recognized As Safe) status as a food additive. Despite this, it remains permitted for use in food products under FDA guidelines as a flavoring agent, as the FDA regulates flavoring substances through its Flavor and Extract Manufacturers' Association (FEMA) GRAS list and other established frameworks. In the European Union, yarrow is listed in the Register of Flavouring Substances used in or on foods, though regulatory frameworks may vary by member state.

The lack of formal GRAS designation does not indicate safety concerns; rather, it reflects that formal GRAS petitions have not been submitted or approved for this particular substance. Manufacturers using yarrow oil must ensure compliance with applicable food regulations in their jurisdiction and use the substance in compliance with safety standards for food additives.

Limited peer-reviewed studies specifically address yarrow oil's safety profile at food-flavoring concentrations. Most available research examines yarrow's traditional medicinal properties or its composition rather than food-safety parameters at typical usage levels. The absence of FDA adverse event reports and recalls suggests a good historical safety record in food applications.

The European Food Safety Authority (EFSA) has evaluated yarrow-related substances in various contexts. Available chemical composition data indicates that yarrow oil profiles vary depending on geographic origin and cultivation methods, which may influence its specific constituent profiles and safety parameters.
