What is Tansy?

Tansy is a plant. The name "tansy" comes from the Greek word "athanasia," which means "immortality." Tansy was thought to confer immortality, so it was used for embalming.

Despite serious safety concerns, the parts of the tansy plant that grow above the ground are used to make medicine.

Tansy is used for digestive tract problems including stomach and intestinal ulcers, certain gallbladder conditions, gas, bloating, stomachache, stomach spasms, and poor appetite.

It is also used for painful conditions including migraines, nerve pain (neuralgia), joint pain (rheumatism) and sciatica; and for heart conditions including rapid heartbeat (palpitations) and fluid retention caused by congestive heart failure.

Some women use tansy to start menstruation or cause an abortion.

Tansy is also used to treat roundworm and threadworm infections in children.

Other uses include treatment of epileptic seizures, colds, fever, hysteria, gout, kidney problems, and tuberculosis. It is also used to kill lice and bacteria; promote sweating; calm the nerves; and act as an antioxidant, tonic, and stimulant.

Tansy is applied directly to the affected area for scabies, itching, bruises, sores, sprains, swelling, freckles, inflammation, vaginal discharge, sunburn, toothache, and tumors. It is also applied to the skin as an insect repellent.

In foods and beverages, tansy is used as a flavoring agent.

In manufacturing, tansy extracts are used in perfume and as a source of green dye.

Be careful not to confuse tansy with tansy ragwort (Senecio species) and other plants generically referred to as "tansy."
