Oregano leaf is a pungent Mediterranean culinary and digestive aromatic. Dried leaves provide flavor, phenolic acids and flavonoids, while the volatile fraction varies by plant type. Essential oil concentrates the aromatic compounds.
Traditional Uses & Why Herbalists Value It
Mediterranean cooks and household herbalists value oregano leaf for its strong aroma in food and digestive infusions. Like other aromatic mint-family herbs, it has a carminative tradition concerned with after-meal comfort. The dried leaf supplies both flavor and nonvolatile plant compounds.
What Modern Research Has Found
Laboratory research has found antimicrobial activity in defined oregano oils and extracts, with carvacrol and thymol important in many oils. Research also describes leaf phenolic acids and flavonoids. These are experimental findings, while human evidence for ordinary leaf tea remains limited.
Plant Part, Preparation & Natural Constituents
The bulk product is leaf. Oregano contains phenolic acids and flavonoids, while its volatile fraction can contain carvacrol and thymol depending on chemotype. Essential oil is much more concentrated than dried leaf.
Oregano leaf in Formulae
Dried oregano leaf is used in culinary mixtures, teas and aromatic herbal formulae. It contributes the familiar warm, pungent character of oregano while remaining far less concentrated than oregano essential oil.
