The minimum carvacrol content of our pure oregano oil is 72%, although once diluted (Certified Organic Olive Oil in our Oréganum Plus 1:1, i.e. 50-50, for instance) this then becomes a minimum of 37.5%. Most companies dilute their oil to a ratio of 1:4 or 1:5, but still list a carvacrol content of 75 or 80% without explaining that this carvacrol content percentage refers to the crude oil and not the final product. We don't guarantee a percentage, because each batch is slightly different. Note that a wild harvested plant will naturally concentrate chemicals differently from season to season and changes in conditions such as rainfall, and temperature. Still, so far our oil has always been at least 72% carvacrol.
