Oregano leaves dried and crumbled. Unusually among herbs, drying suits oregano — the carvacrol concentrates and the flavour deepens rather than fading.
What it does in a recipe: A concentrated peppery savoury note for sauces, marinades and rubs, added early so the oils have time to disperse. Pick the swap that covers that job — the ratios below are written so you can act on them without doing any arithmetic.

Allergen checkBecause this is a manufactured mix, its non-herb ingredients vary and some carriers are wheat-derived. Scan the label if gluten matters in your kitchen, and speak to the manufacturer directly where the stakes are medical.
Worth knowing
Store dried oregano away from the stove. Heat and light strip volatile oils faster than time does, and a jar kept above the hob will be spent within months.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter — confirm with the manufacturer or your clinician rather than relying on a substitution chart.
