Mexican oregano, like many other herbs, comes from the mint family. In New Mexico and California the leaves of several plants in the Lippa genus are harvested and dried before use. The visual characteristics of Mexican oregano are similar to that of Greek oregano but the aroma and taste have distinctly different qualities.
Mexican oregano is a bit stronger, less bitter and less minty than the Greek species. It is widely used in Southwestern and Mexican cooking and is a staple ingredient in our chili powders.
