NOW Foods Oil of Oregano 25%: What to Know
Two things here are genuinely useful and one is a trap, so read the number first.
The 25 percent is a dilution figure, not a carvacrol figure. It means the bottle contains 25 percent oregano oil with the remainder being a carrier, so three-quarters of the volume is not oregano oil at all. That is not a flaw: a pre-diluted oil is substantially easier to use safely than a neat one, it is far more forgiving of a heavy hand, and it is the sensible format for anyone new to this. The trap is that 25 percent sitting in a title in a category where the meaningful number is a carvacrol percentage of 80 or 90 invites exactly the wrong comparison. These two numbers measure different things, and a diluted oil's carvacrol content is a proportion of its oregano oil fraction, which this listing does not state.
NOW Foods is the genuine advantage. It is a long-established supplement manufacturer with a real company behind it, which in a category with a documented adulteration problem is worth something on its own.
Now the problems, and they are with the listing rather than necessarily the product. Its three bullets are a SKU dump: oil of oregano 25% 1 oz by now foods, then a string reading NOWCOSMETIC Vitamin-Aromatherapy 1OZ, then a UPC. There is no usage information, no carvacrol figure, no species, no origin and no directions of any kind. The detail table records the special feature as Aromatherapy and gives the item form as Capsule, which cannot be right for a one-ounce liquid.
That aromatherapy categorization is the thing to notice. Aromatherapy and cosmetic products sit in a different regulatory lane from dietary supplements, with different labelling requirements and no Supplement Facts panel. If you intend to take an oregano oil internally, buying a product this listing files under aromatherapy, with no directions and no stated composition, is a reason to check the physical bottle's own labelling before doing anything with it, or to choose one of the clearly labeled supplements in this guide instead.
