Calendula officinalis, also known as pot marigold, is a perennial with bright orange and yellow flowers. In traditional medicine, Calendula officinalis has been used both orally and topically due to its anti-inflammatory activity. Today, Calendula officinalis is still widely used in skin care formulations. In fact, a report published in Pharmacognosy Review found that more than 200 different commercial and medical formulations now contain concentrated Calendula officinalis flower extract.
