Intolerances
- SalicylateHigh
Dried oregano is one of the four culinary herbs an RP-HPLC measurement placed highest in salicylate, alongside cloves and behind dried basil and cumin. Drying is what puts it there: taking the water out leaves the salicylate in a fraction of the weight, so the fresh herb is the lower form of the same plant.

- Histamine (+liberators / DAO inhibitors)Low
Oregano contains no histamine. A pinch on a pizza is the usual dose, and drying has already removed the water bacteria would need. Herbs are among the few things on this axis that can be used freely, and what SIGHI publishes for them is a compatibility rating rather than a content.
