Calendula officinalis, the pot marigold, ruddles, common marigold or Scotch marigold, is a flowering plant in the daisy family Asteraceae. It is probably 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.

The Latin specific epithet officinalis refers to the plant's medical and herbal uses.

Uses:

Pot marigold 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.

Marigold 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.
Constituents

The petals and pollen of Calendula officinalis contain triterpenoid esters and the carotenoids flavoxanthin and auroxanthin (antioxidants and the source of the yellow-orange coloration). The leaves and stems contain other carotenoids, mostly lutein (80%), zeaxanthin (5%), and beta-carotene.[ed] Plant extracts are also widely used by cosmetics, presumably due to presence of compounds such as saponins, resins, and essential oils.

The flowers of Calendula officinalis contain flavonol glycosides, triterpene oligoglycosides, oleanane-type triterpene glycosides, saponins, and a sesquiterpene glucoside. Calendula flowers are a rich source of lutein, containing 29.8mg/100g.
Potential pharmacology

Plant pharmacological studies have suggested that Calendula extracts may have anti-viral, anti-genotoxic, and anti-inflammatory properties in vitro. In an in vitro assay, the methanol extract of C. officinalis exhibited antibacterial activity and both the methanol and the ethanol extracts showed antifungal activities.

Along with horsetails (Equisetum arvense), pot marigold is one of the few plants which is considered astringent despite not being high in tannins.
