They are different herbs. Turkish oregano is Origanum vulgare--common European oregano that happens to come from Turkey. It's what's sold as "oregano" on the supermarket spice rack.
Mexican oregano is Lippia graviolens, a different plant entirely.
I have always used common oregano and have never been able to find Mexican oregano on the shelves of local markets. I ran out of oregano recently and while shopping at Lull Farm in Hollis NH I discovered--side by side on the shelf--Turkish and Mexican oregano, packed by the same spice company. I bought a bottle of each. The two spices look and smell quite different.
Any particular recipes out there that showcase Mexican oregano?
