Tansy

Tansy (Tanacetum vulgare) is a perennial, herbaceous flowering plant of the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive.

Description

Tansy is a herbaceous perennial plant, often deemed as a weed. It can grow to a height of 50–150 cm, and its flowers are button-like and bright yellow. Tansy has a strong, aromatic scent and a spicy, somewhat bitter taste.

Distribution and habitat

Tansy is native to Eurasia; it is found in almost all parts of mainland Europe. It is absent from Siberia and some of the Mediterranean islands. The plant prefers sunny, dry locations and soils rich in nitrogen.

Uses

Historically, tansy has been used for medicinal purposes, although it is toxic and can cause death if consumed in large amounts. The plant has also been used as a culinary herb and to repel insects.

Toxicity

Tansy contains a volatile oil which can cause contact dermatitis in sensitive individuals. If ingested, it can cause severe toxicity.

Control

In some areas, tansy is considered an invasive species, with control measures being used to restrict its spread.
