Zane Hellas Oregano Oil 164mg Carvacrol Per Serving: What to Know
This takes a different and arguably better approach to the potency question. Instead of a percentage, it states both quantities per serving: 190mg of oregano oil delivering 164mg of carvacrol, with the serving defined as four drops daily. That lets you calculate the proportion rather than take a claimed percentage on trust, and it simultaneously tells you what a serving is, which most listings in this category leave vague.
Defining the serving in drops is the practical half of that. A bottle volume tells you nothing about how long it lasts; four drops a day does.
The oil is 100 percent Greek and undiluted, with the species identified in the bullets as Origanum vulgare, described as the well-known variety indigenous to Greece. Origin and species are both stated, as with the other two drop products here.
The listing also makes the most sensible point of any here about why the compound matters, noting that carvacrol is the main compound in oregano oil and that it has been studied extensively. That framing is correct in itself, though the existence of research on a compound is not evidence about a product.
Two honest notes. The bullets are the most aggressive in this group, with headings like Restore Your Health and language about the immune system being constantly under attack, and one of them claims over a hundred studies without citing any. That is marketing and should be read as such; the reason this product is here is the two numbers in its title, not those bullets. And the brand field in the detail table reads Zane HELLAS Probably the best oregano oil products in the world, which is a marketing slogan stuffed into a structured data field rather than a brand name, and is a reasonable prompt to treat the listing's other unquantified claims with some caution.
