Conclusion
The roots and flowers of B. perennis have been used for many years in traditional medicine to treat various conditions, including skin disorders. While modern scientific interest has been piqued, the current body of evidence is meager. Much more research is necessary to determine the potential role of topical B. perennis in the dermatologic armamentarium. But recent data and the history of traditional use suggest that such research is warranted.
