Calendula officinalis, also known as the pot marigold, ruddles, common marigold or Scotch marigold, is a flowering plant in the daisy family Asteraceae. It is native to southern Europe, though its long history of cultivation makes its precise origin unknown, and it may possibly be of garden origin. It is also widely naturalised farther north in Europe (as far as southern England) and elsewhere in warm temperate regions of the world.
Calendula florets are edible. They are often used to add color to salads or added to dishes as a garnish and in lieu of saffron. The leaves are edible but are often not palatable. They have a history of use as a potherb and in salads.
Flowers were used in ancient Greek, Roman, Middle Eastern, and Indian cultures as a medicinal herb, as well as a dye for fabrics, foods, and cosmetics. Many of these uses persist today. They are also used to make oil that protects the skin.
Calendula leaves can also be made into a poultice that is believed to help scratches and shallow cuts to heal faster, and to help prevent infection.
It is often used as a complementary or alternative treatment. Calendula has antifungal, anti-inflammatory, and antibacterial properties that might make it useful in healing wounds, soothing eczema, and relieving diaper rash.
