Traditional Use (May Not Be Supported by Scientific Studies)Since the time of the ancient Greeks, pennyroyal was considered a useful insect repellant, reflected in modern times by the common name fleabane.1 The Latin names of both plants also reflect this insect-repelling power—pulegoides and pulegium both derive from the Latin word for flea. It was also believed to stimulate menstruation. Various folk herb traditions have employed American or European pennyroyal to help relieve coughs, upset stomachs, and anxiety.2 Copyright © 2025 TraceGains, Inc. All rights reserved.
