Oregano
Mediterranean herb with carvacrol and thymol
What is this ingredient?
Oregano is a boldly aromatic herb from Mediterranean culinary tradition. Its name means 'joy of the mountain' in Greek, referring to the places where wild oregano grows well. Its distinctive aroma and flavor come mainly from carvacrol and thymol, two phenolic compounds in the essential oil fraction. Dried oregano is often more intense than fresh oregano because the leaves become more concentrated and hold their aroma well. This makes it especially useful in tomato sauces, pizza, grilled vegetables, legumes, olive oil marinades and Greek salads.

Good Combinations (Synergy)
Combine oregano smartly to enhance the effect:
Three polyphenol pathways in one Greek salad
Technical: Kalamata olives contain hydroxytyrosol (3.5mg/100g) and oleuropein — polyphenols from the phenol class. Tomato provides lycopene (2573μg/100g), a carotenoid. Oregano contains carvacrol and thymol, terpene compounds. This trio forms a polyphenol-carotenoid-terpene complex working through three different biochemical pathways.
What does this mean for you? Greek salad (tomato, olives, oregano) is a culinary classic combining three entirely different categories of bioactive compounds. Each ingredient delivers a different type of polyphenol — broader together than apart.
Fat makes carvacol and thymol absorbable
Lambert JD et al. (2004) in Molecular Nutrition & Food Research showed that dietary fats enhance absorption of phenolic compounds from herbs.
Technical: Oregano contains carvacrol (60-74%) and thymol (1-5%) — potent phenolic compounds with broad bioactivity, traditionally valued in food preservation. These compounds are fat-soluble and poorly absorbed without fat. Olive oil dissolves them and significantly increases their bioavailability. This explains why oregano oil always comes in a carrier oil.
What does this mean for you? Cook oregano in olive oil or make oregano-olive oil dressing. The bioactive compounds in oregano are fat-soluble — without oil you barely absorb them.
Mediterranean synergy - antioxidants stabilize lycopene
Böhm V et al. (2002) in Journal of Nutrition showed that antioxidants improve lycopene stability.
Technical: Oregano's antioxidants (rosmanol, carvacrol, thymol) protect lycopene from tomato against thermal degradation during cooking. Lycopene is heat-labile but released from cell walls by heating. The herbs act as an antioxidant shield: they scavenge free radicals that would break down lycopene.
What does this mean for you? Add oregano to tomato sauce during cooking. The oregano protects the lycopene while heat releases it — that's why Italian tomato sauce with oregano is so healthy.
Thymol + carvacrol work synergistically as natural preservation
Technical: Thyme contains thymol (20-54%) and oregano contains carvacrol (60-74%). Both are phenolic compounds disrupting cell membranes of microorganisms but through different binding sites. Studies (Burt, 2004) show the combination works synergistically — bioactivity exceeds the sum of individual effects.
What does this mean for you? Use thyme and oregano together as herb mix on pizza, in sauces or as meat marinade. Two herbs with similar but complementary bioactive action — traditionally also valued for food preservation.

Shelf life:vers 1 week, gedroogd 1-3 jaar
Store dried oregano in an airtight jar in a dark, dry place. Wrap fresh oregano in a lightly damp cloth and keep it in the fridge.
Preparation
Dried oregano can be added early to tomato sauces, stews and baked dishes so its aroma spreads well. Add fresh oregano closer to the end. It is classic with pizza, pasta, grilled meat, grilled vegetables, Greek salad, feta and olive oil.
Substitutes
Smart preparation
1Dried oregano is more intense than fresh oregano; start with about half the amount.
2Rub dried oregano between your hands before adding it.
Why?
This breaks the leaves and releases the aroma faster into a sauce, dressing or marinade.
3Add dried oregano early to sauces; add fresh oregano closer to the end.
Caution / Warnings
Oregano is very safe, but there are scientific considerations:
Allergy to the Lamiaceae family Moderate
People allergic to basil, mint, lavender or thyme may also react to oregano.
Advice:
Avoid oregano with a known allergy to the Lamiaceae family.
Blood thinners Moderate
Dried oregano contains a high amount of vitamin K per 100 g; in normal culinary use, the portion is usually small.
Advice:
With blood thinners, use normal culinary amounts and avoid concentrated supplements without personal advice.
Traditional use
Mediterranean
Mountain herb of the Greeks
Oregano comes from the Greek 'oros ganos' (joy of the mountain). In Greek cooking, it has long been a staple herb for grilled meat, olive oil, lemon, feta, salads and tomato dishes.
Summary
Oregano gives dishes a deep Mediterranean flavor with warm, slightly bitter and peppery notes. Carvacrol and thymol largely shape oregano’s recognizable aroma, especially in dried form. Use it in tomato sauces, pizza, grilled vegetables, legumes and olive oil marinades. Dried oregano has a strong flavor, so a small amount is often enough.
