Tansy (Tanacetum vulgare)

From Wikipedia -
Tansy (Tanacetum vulgare) is a perennial, herbaceous flowering plant of the aster family Asteraceae. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons.
Tansy is native to Eurasia; it is found in almost all parts of mainland Europe, as well as Britain and Ireland. It is absent from Siberia and some of the Mediterranean islands. The ancient Greeks may have been the first to cultivate it as a medicinal herb. In the sixteenth century it was considered to be "necessary for a garden" in Britain.
It has been introduced to other parts of the world including North America, and in some areas has become invasive.
Tansy has a long history of use. It was first recorded as being cultivated by the ancient Greeks for medicinal purposes. In the 8th century AD it was grown in the herb gardens of Charlemagne and by Benedictine monks of the Swiss monastery of Saint Gall. Tansy was used to treat intestinal worms, rheumatism, digestive problems, fevers, sores, and to bring out measles.
During the Middle Ages and later, high doses were used to induce abortions. Contradictorily, tansy was also used to help women conceive and to prevent miscarriages. In the 15th century, Christians began serving tansy with Lenten meals to commemorate the bitter herbs eaten by the Israelites. Tansy was thought to have the added Lenten benefits of controlling flatulence brought on by days of eating fish and pulses and of preventing the intestinal worms believed to be caused by eating fish during Lent.
Tansy was used as a face wash and was reported to lighten and purify the skin. In the 19th century, Irish folklore suggested that bathing in a solution of tansy and salts would cure joint pain. Although most of its medicinal uses have been discredited, tansy is still a component of some medicines and is listed by the United States Pharmacopeia as a treatment for fevers, feverish colds, and jaundice.
Tansy has also been cultivated and used for its insect repellent and in the worm warding type of embalming. It was packed into coffins, wrapped in funeral winding sheets, and tansy wreaths were sometimes placed on the dead. Henry Dunster, the first president of Harvard University, was buried wearing a tansy wreath in a coffin packed with tansy; when “God’s Acre” was moved in 1846 the tansy had maintained its shape and fragrance, helping to identify the president’s remains. By the 19th century, tansy was used so much at New England funerals that people began to disdain it for its morbid association with death.
During the American colonial period, meat was frequently rubbed with or packed in tansy leaves to repel insects and delay spoilage. Tansy was frequently worn at that time in shoes to prevent malaria and other fevers; it has been shown, however, that some mosquito species including Culex pipiens take nectar from tansy flowers.
Tansy can be used as in companion planting and for biological pest control. It is planted alongside potatoes to repel the Colorado potato beetle, with one study finding tansy reduced the beetle population by 60 to 100%.
In England tansy is placed on window sills to repel flies; sprigs are placed in bed linen to drive away pests, and it has been used as an ant repellent.
In the 1940s, distilled tansy oil mixed with fleabane, pennyroyal and diluted alcohol was a well known mosquito repellent; collectors were paid five cents a pound for tansy in full bloom. Research has found that tansy extracts do indeed repel mosquitoes, but not as effectively as products containing DEET. In 2008, researchers in Sweden investigated the use of tansy to repel ticks, showing a 64–72% repellency for each oil constituent.
