Doesn't look too bad. Oregano isn't something people take regularly, so I assume you're taking it for an infection of some sort? I see nothing wrong with that product if it's being used on a limited basis.
Everyday is a little different. I'm sure the amounts of PUFA in that is microscopic by comparison to what you find even in "low-PUFA" foods.
But cutting back wherever is ideal. For future reference, I find Barlowe and Hawaii Pharm to have the most pure botanicals on the market. I don't know if either has oregano, but their the vendors I'd check first just due to their clean product standards.
