What is Erigeron, Oil?
Erigeron oil (CAS Number 8007-27-0) is an essential oil extracted from Erigeron canadensis L., commonly known as horseweed, Canadian fleabane, or butterweed. This plant is native to North America and belongs to the Asteraceae family. The oil is obtained through steam distillation or solvent extraction of the plant material and contains volatile aromatic compounds that contribute distinctive herbal and slightly bitter flavor characteristics.
Common Uses
Erigeron oil functions as a flavoring agent and flavor adjuvant in the food industry. It is primarily used in beverages, baked goods, confectionery, and other processed foods where herbal or botanical flavor profiles are desired. The oil's aromatic properties make it useful in creating natural and plant-based flavor formulations. Typical usage levels are minimal, as essential oils and flavor compounds are generally used at parts-per-million concentrations to achieve desired sensory characteristics without overwhelming other flavor components.
Safety Assessment
Erigeron oil has generated no reported adverse events in the FDA database and has not been associated with any recalls. The lack of adverse event reports suggests a generally favorable safety profile in food applications at typical usage levels. As with most essential oils used in flavoring, safety considerations center on appropriate concentration levels and intended use. The volatile nature of essential oils means they dissipate during food processing and storage, further reducing potential exposure concerns.
While the oil is not on the FDA's GRAS (Generally Recognized as Safe) list, this designation does not indicate a safety concern. Many traditional plant-derived flavoring agents, particularly those with limited commercial use or older botanical sources, are not formally GRAS-listed but are considered acceptable for use under FDA's flavor regulations (21 CFR Part 182). The lack of toxicological reports or safety alerts suggests adequate safety margins in current food applications.
Regulatory Status
Erigeron oil is not listed on the FDA's GRAS inventory, indicating it operates under different regulatory provisions. However, it appears in various food additive databases and is permitted for use as a flavoring agent in many jurisdictions. In the European Union, botanicals and their derivatives used as flavoring substances are subject to EFSA (European Food Safety Authority) evaluation. The absence of regulatory warnings or restrictions suggests acceptance as a food-grade flavoring ingredient.
Manufacturers using erigeron oil in food products must comply with FDA regulations for natural and artificial flavoring substances, including proper labeling and documentation of ingredient sourcing and processing methods. The ingredient may be listed on food labels as "erigeron oil," "erigeron canadensis oil," or simply as a botanical flavoring, depending on labeling regulations and product formulation.
Key Studies
Limited peer-reviewed literature specifically addresses erigeron oil's safety in food applications. Most research on Erigeron canadensis focuses on its traditional medicinal uses in herbal preparations rather than food flavoring applications. The plant has been used in traditional North American herbalism, though such use does not substitute for food safety data.
General toxicological principles for essential oils and volatile flavor compounds suggest that erigeron oil would present minimal systemic exposure through typical food consumption. The regulatory history—with zero adverse events and zero recalls—provides practical evidence of safe use in food products over years of commercial application.
Future research could include comprehensive compositional analysis of erigeron oil batches, stability testing in various food matrices, and confirmation of flavor compound identity and concentration. Such studies would further establish the safety profile and optimize its application in food formulations.
