Calendula, a flowering plant also known as pot marigold, can be served as a tea or used as an ingredient in various herbal formulations. The flower petals of the calendula plant, or pot marigold, have been used for medicinal purposes since at least the 12th century. Calendula is native to Mediterranean countries and is found in many parts of Egypt. Calendula has high amounts of flavonoids, plant-based antioxidants that protect cells from being damaged by unstable molecules called free radicals. Calendula appears to fight inflammation, viruses, and bacteria. Calendula has been shown to help wounds heal faster, possibly by increasing blood flow and oxygen to the affected area, which helps the body grow new tissue.
