Blessed thistle, sometimes called holy thistle or Saint Benedict thistle, is a Mediterranean native with a long history of mention in European herbal and monastic traditions. Historical records note its inclusion in elaborate herbal blends, including those developed by Benedictine monks such as Don Bernardo Vincelli. Today, blessed thistle still lends its flavor to Benedictine liquor (although the complete recipe is a closely guarded secret). The herb is also enjoyed in digestive tea blends and herbal bitters.
