Marigold oil, derived from the petals of the pot marigold (Calendula officinalis), is celebrated for its vibrant flowers, which contain beneficial compounds such as flavonolglycosides, triterpene glycosides, saponins, and sesquiterpene glucosides. Historically, marigold flowers have been a staple in culinary practices, particularly in German soups and Mediterranean dishes, contributing both color and flavor. The term "pot marigold" reflects its culinary use, as the colorful petals enhance butter and cheese, while the flowers have also been used as a natural dye for fabrics.
The extraction of marigold oil occurs through steam distillation, with the flowers blooming from May until the first frost. The name "marigold" is derived from the Anglo-Saxon term "merso-meargealla," meaning "marsh marigold." The flower holds cultural significance, often associated with the Virgin Mary and Queen Mary of the 17th century, and is surrounded by various folktales. One such belief suggests that cutting the flowers when the sun is at its zenith may yield heart-tonic benefits.
