The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Description of Plant(s) and Culture

Tansy was once valued as a pot herb. It can be recognized by its feathery leaves and clusters of bright yellow button-like flowers. Full sun or partial shade. Zones 4-9.

Tansy is an aromatic, perennial plant which is cultivated and also found growing wild. The short creeping rootstock sends an erect, nearly round, often purplish-brown stem to a height of 1-5 feet. The alternate, smooth, lanceolate, dark green, fernlike, leaves are pinnately divided, their segments acute and toothed. Blooming from July to September, the golden-yellow flowers (1/2 inch rayless buttons) grow in terminal, flattened cymes. The fruit is an achene (a small, dry fruit with one seed which is attached to the ovary wall only at one point).

Pick tansy blossoms for drying as an ornamental in dry arrangements. Do not use tansy as a tea, food, or medicine; it can be toxic.

Legends, Myths and Stories

Tansy’s generic name, Tanacetum, is from the Greek word athanasia, “immortality”; in times past, coffins were filled with tansy to preserve corpses precisely because the flowers do not wilt when dried.

Tansy was mentioned in writings as early as 5,000 BC. It reached its height of popularity in the Middle Ages.

The whole plant has a camphoraceous odor. The plant is cultivated today for the oil which is so powerful that its use is not recommended except by a medical practitioner.
Used for thousands of years, until about the mid 19th century, as an embalming agent.

Tansy is still used by some cultures for culinary as well as medicinal purposes.

Tansy, a native of Europe, was one of the first plants brought to North America by European settlers; even before the Revolution it has escaped colonial gardens and was showing up along roadsides.

In old-time gardens, tansy was grown around peach trees as a preventative against insects.
