Mexican Oregano

Unlike Mediterranean Oregano, Mexican oregano is from a different plant family called, Verbenaceae.  Mexican Oregano has citrus-like undertones but also might taste grassier or earth.
 
Mexican Oregano has undertones that seem to be a more natural fit with Mexican cuisine and we highly recommend that any Mexican style cooking you do to use the REAL thing rather than just substituting it for the more common Mediterranean Oregano.
