It was believed to be a powerful digestive aid, and it was also used to treat a variety of other ailments such as fevers, headaches, and even as a love potion. In the 18th and 19th centuries, it became a popular ingredient in French cuisine, particularly in the region of Normandy. It is known as the "gourmet's parsley" and was used to flavor many dishes, including soups, stews, and omelets.
