Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tansy (Tanacetum vulgare) has a long history of traditional use as an insect repellant, particularly in European folk practices. Historically, tansy leaves and flowers were placed in bedding, strewn on floors, or tucked into clothing to ward off flies, fleas, and other insects. This practice dates back to at least the Middle Ages. The plant's aromatic compounds, especially thujone, are thought to contribute to its repellent properties, although traditional users would not have known the specific chemicals involved.

In terms of scientific validation, there is limited research directly assessing the efficacy of tansy as an insect repellent. Some laboratory studies have identified tansy's volatile oils, such as thujone and camphor, as having insecticidal or repellent effects, but these studies are not extensive or conclusive. The use of tansy in modern, evidence-based insect repellents is uncommon, and health authorities do not generally recommend it for this purpose, partly due to concerns over toxicity (especially thujone content) with prolonged or concentrated use. Overall, while tansy's use as an insect repellent is strongly rooted in tradition and supported by some preliminary laboratory findings, robust scientific evidence remains limited.
