Yeah--did you read about that Seri oregano, for starters?
There are many oreganos in the world, but one of the most pungent and flavorful is the Sonoran oregano (Lippia graveolens) that is hand-harvested from the islands and coast of the Gulf of California by the Seri Indians, an endangered people. The Seri have long used this oregano for its culinary, medicinal, and ceremonial properties, which include it being ranked among the world's top plants for antioxidant protection against the maladies of aging—even better than vitamin E. It is now one of the few sustainably harvested cash products that they can market directly to chefs, gift shops and enlightened consumers in the U.S.
