Calendula officinalis, the pot marigold, common marigold, ruddles, Mary's gold 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 medicinal and herbal 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. The plant is also used to make tea. 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. It has also been used in eye drops. Marigold has long been recognised as a medicinal flower to address cuts, soars and general skin care, because it contains essential oils and a high concentration of flavonoids (secondary plant substances), such as carotene. They act as anti-inflammatories to promote topical healing and soothe irritated skin. Topical treatment with a diluted marigold solution or tincture accelerates healing of wounds and rashes. Research has found that Calendula extract is effective in the treatment of conjunctivitis and other ocular inflammatory conditions. The extract demonstrates antibacterial, anti-viral, antifungal and immuno-stimulating properties that were shown to reduce eye infections. The vision is also protected by these extracts, guarding the delicate tissues of the eye from UV and oxidative damage. Moreover, it is also an effective remedy for sore throats, gingivitis, tonsillitis and mouth ulcers. Gargling with Marigold tea will help to soothe the mucus membranes of the throat whilst easing the pain.
