Is Oregano Acidic or Alkaline?
Oregano (dried) is strongly alkaline: Negative PRAL: alkalizing after digestion.
Classification
Dried oregano comes in at −44.4 because drying concentrates the potassium and calcium in the leaves into a fraction of the weight. In everyday cooking this matters less: a teaspoon weighs about one gram and contributes about −0.4 to your balance. On pizza, oregano is seasoning. It does not offset the acid load from the dough and cheese.
In the Herbs, Spices & Sauces category, oregano (dried) ranks #4 of 75, sorted from alkaline to acid-forming. More alkaline options include Sage (−46.5), Tarragon (−64.5), Chervil (−92.5). More acid-forming are Paprika powder (−36.2), Turmeric powder (−35.5), Chili powder (−31.4).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is oregano acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Oregano (dried) has a PRAL of −44.4 per 100 g, so it counts as strongly alkaline in your daily acid-base balance.
How much oregano do I need for a noticeable effect?
A teaspoon (5 g) of oregano adds −2.2 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of oregano roughly offsets one of them.
Why is oregano alkaline even though it is not a typical alkaline food?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Oregano provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−44.4).
