NOT A CO2 EXTRACT, it is ethanol, read the label.

Not a CO2 extract, it’s an ethanol extract, and it says this in small print on the bottle’s label.Clearly it’s being advertised as a CO2 extract, when in fact, it is an ethanol based extract in a cheap sunflower carrier oil. Not even pure essential oil.Worse yet, it’s non-returnable.Company reported for false and misleading advertising.

Not Pure Rosemary CO2 extract

Im sure it works as intended but has sunflower oil as a carrier oil. Seller should inform buyers. This is NOT pure Rosemary CO2 extract.
