Calendula, also known as calendula officinalis, was used as a medicine or dye in the ancient West. It can also be used as cosmetics or food. Its leaves and petals are edible, so it can be used as a decoration for dishes. The orange-yellow flowers are like the marigolds of the sun, also known as evergreen flowers, which are native to southern Europe and the Mediterranean coast. It is said that the ancient Romans saw marigolds bloom on the first day of the new year, so they named it after "Calends" (the first day of the Roman calendar), which is the origin of its genus name. The ancient Egyptians believed that calendula could delay the aging process, while the Indians respected it as a sacred flower. In the Middle Ages, it was widely used by Europeans to treat skin diseases and wounds and fight plague and black death.
