Tansy

A perennial, vigorously growing plant with yellow umbels, which are very strong as cut flowers. The height is (depending on the location) 80-150 cm and flowering begins in June with a second flush of blooms lasting well into autumn. The botanical name "Tanacetum" is presumably derived from the Ancient Greek word "athanasia" meaning "immortal". It probably owes this name to the fact that the flowers do not wilt easily and retain their yellow color for a long time, but it could also refer to a kind of elixir of life made from it. Tansy was also used for preserving bodies.
The glandular hairs on the elegantly feathered leaves are responsible for the typical camphor-like scent, which signals that the plant might be poisonous. Well, it is: the oil that can be extracted from the plant is poisonous in principle, a reason why it is forbidden to sell the plant in the United States (which is, of course, nonsensical, within medicine we precisely use that poison in the correct dosage). Ants do not like tansy, which is why the herb used to be planted near kitchen doors.
Medicinal properties: externally it can be used as a lotion for scabies. Some tansy placed in shoes was said to help against chronic fever. In phytotherapy, it is used against, among other things, arthritis and colds. The plant contains the toxic thujone, which is anthelmintic (roundworms and tapeworms). Incorrect doses cause dizziness, cramps, abdominal pain, and can be fatal.
Pesticide: the essential oils from the plant, such as triticin, irisine, and graminine, are used in recipes for insect repellents.
As food: in small quantities, tansy is mixed into green cakes or oven cakes and used to improve the taste of eggs.
Dye plant: the flower is a grateful "supplier" of yellow dye.
