Tansy is a perennial herb with fern-like leaves and clusters of bright yellow button-like flowers. It has a strong, aromatic scent and a bitter taste. Historically, tansy has been used in traditional medicine for its supposed medicinal properties, although its internal use is now cautioned due to its potential toxicity. In modern times, tansy is primarily used as an ornamental plant and is valued for its attractive appearance and ability to repel insects. It is also sometimes used in herbal insect repellents and for decorative purposes in gardens and floral arrangements.
