Fliou (pronounced "flee-oh") is the Moroccan Arabic word for pennyroyal (Mentha pulegium), an aromatic mint plant used to flavor Moroccan tea. Its pungent flavor and aroma are pleasantly stronger than spearmint (na'na), which is more often used when making Moroccan Mint Tea.

In traditional medicine, pennyroyal infusions and aromatherapy are used to treat respiratory ailments, colds, flu, and gastrointestinal disorders.

Despite these benefits, it is important to note that the essential oil of pennyroyal is quite toxic.
