Chrysanthemum cinerariifolium is also known as pyrethrum or Dalmatian chrysanthemum due to its origin in Dalmatia, Croatia. This flowering plant is mostly used for its insecticidal properties and is commonly known as a natural pesticide. Pyrethrum contains pyrethrins, a compound that paralyzes insects' nervous systems, resulting in their death. Other synonyms of chrysanthemum cinerariifolium include Tanacetum cinerariifolium, Dalmatian insect flower, pellitory, and feverfew. Pellitory is commonly used for medicinal purposes, and feverfew is an herb used for migraine relief. Dalmatian insect flower is also used as a natural remedy for lice, fleas, and ticks on dogs and cats.
