Pot Marigold or English Marigold (Calendula officinalis) is a plant in the Calendula genus. It was used in ancient Greek, Roman, Arabic and Indian cultures as a medicinal herb as well as a dye for fabrics, foods and cosmetics.
The leaves and petals of the Pot Marigold are edible, with the petals added to dishes as a garnish and in lieu of saffron. The leaves can be sweet but are more commonly bitter, and may be used as or as part of salad.
It is also used in homeopathic medicine (in a gel form) as a way to promote the healing of minor burns, scrapes and skin irritations.

Pharmacology
Plants are used for the treatment of skin disorders and pain, and as a bactericide, antiseptic and anti-inflammatory. The petals and pollen contain triterpenoid esters (an anti-inflammatory) 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%) and zeaxanthan (5%), and beta-carotene. Plant extracts are also widely used by cosmetics, presumably due to presence of compounds such as saponins, resins and essential oils. Organic extracts have even been tentatively shown to inhibit HIV-1. [1]
