North American Herb&Spice was the first company on the American market to introduce edible Oil of Oregano. We are the oregano experts! This was the result of extensive research and the personal experiences of the company s founders. To be edible, this essential oil must be made only from wild, mountain-grown, Mediterranean oregano, free of all chemicals and pesticides. It also has to be emulsified in a carrier oil such as extra virgin olive oil, which is used by North American Herb&Spice in its Oil of Oregano. The oregano we use is the real, 100% Mediterranean oregano, guaranteed to be handpicked in the pristine, untarnished wilderness. Our oil is produced by old-fashioned cold pressing and steam distillation. We use no chemicals to extract it.
