Lepechinia floribunda

Lepechinia floribunda, a Chilean mint relative, is used by several regional traditions as a fragrant, bitter-infusion. In southern Chile, among Mapuche communities, the aerial flowering tops are made into a lightly simmered tea and sometimes combined with other aromatic mints as a mild digestive and respiratory tonic; the use is recorded in Chile’s ethnobotanical literature and noted by folklorists (Hoffmann, Flora Silvestre de Chile). In nearby coastal and Andean communities along the cordillera, an infusion of the fresh herb is also taken for stomach discomfort and minor colds. Across the Atlantic, in the Canary Islands, L. floribunda (known locally as poleo de monte) is gathered for a gently brewed, aromatic tea believed to aid digestion and colds; references to “poleo de monte” as L. floribunda are noted in Canarian ethnobotanical literature and local floras (Pérez de Paz & Hernández, 1992; Gil González et al., 1990). In the northern Andes of Venezuela, herbal compendia cite L. floribunda as the source of an infusion used as a carminative tea; the herbal texts further associate this plant with other Lepechinia species in Venezuelan medicinal practice (Rossi, Plantas Medicinales de Venezuela).

A practical, gentle tea preparation can be made from the fresh or dried flowering tops. Use roughly 1 to 2 teaspoons of lightly chopped aerial parts per cup of near‑boiling water, cover, and steep 5 to 10 minutes; strain before drinking. For a stronger bitter taste and digestive emphasis, double the herb and simmer a covered infusion 10 minutes, then cool to a comfortable sip. Dose varies locally; many households limit the infusion to one or two cups a day. The taste is strongly minty with resinous bitterness, and the cooling effect on the tongue supports its popular use as a carminative. In the Canary Islands the “poleo de monte” infusion is also enjoyed chilled or iced. Safety notes: the bitterness can be strong for some; avoid high‑dose, prolonged use in pregnancy; stop if stomach pain worsens or any rash develops and seek advice from a knowledgeable practitioner.

Well‑established constituents explain the traditional effects. The essential oil is rich in monoterpenes, chiefly 1,8‑cineole and camphor, with limonene, p‑cymene, and α‑ and β‑pinene regularly reported in chemical surveys of L. floribunda oil. The aerial parts also contain diterpenes including carnosic acid and rosmarinic acid, and flavonoids such as luteolin, apigenin, and their glucosides; these are all well‑documented constituents for the genus. The menthol‑like oils and rosmarinic acid contribute plausible antispasmodic, carminative, and antimicrobial actions.

Today, the species continues to be harvested in parts of Chile and the Canary Islands for local tea and by artisan distillation for its aromatic oil. Research on the genus continues to profile its antimicrobial and antioxidant activity, and dried leaves appear in local herbal shops as “poleo de monte” in Spain and as a fragrant herbal infusion in Chilean markets.
