Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Phenolic monoterpenes responsible for the strong antimicrobial activity.
Antioxidant constituents.
Aromatic constituents; thujone is the safety-limiting compound.
Antioxidant and anti-inflammatory constituents associated with the cognitive effects.
Pharmacological Actions
Antimicrobial (antibacterial and antifungal via carvacrol and thymol) - supports respiratory and gastrointestinal infections; a small clinical study found emulsified oregano oil cleared enteric parasites (incl. Blastocystis hominis) and improved gut symptoms

Safety, Cautions & Contraindications
Culinary amounts are safe. Concentrated oregano essential oil is a strong irritant - dilute well before any topical use and do not take undiluted oil internally.
May lower blood sugar and has a mild antiplatelet effect, so use caution with antidiabetic or anticoagulant medicines; avoid medicinal/oil doses in pregnancy. Allergy is possible in people sensitive to the mint family (Lamiaceae).
The essential oil contains thujone, which is neurotoxic and can trigger seizures in high doses - do not exceed recommended doses and do not take the pure essential oil internally; avoid medicinal doses in epilepsy.
Avoid medicinal and essential-oil doses in pregnancy and breastfeeding (thujone; sage may also reduce milk supply). Culinary amounts are safe.

Botanical Description
Perennial herb/subshrub (Lamiaceae), 20-80 cm tall, with square, often reddish, downy stems. Leaves are opposite, ovate and aromatic. Small purplish-pink (occasionally white) flowers are borne in dense, flattened, corymb-like clusters at the branch tips.[11]
Evergreen, woody-based perennial subshrub (Lamiaceae), 30-70 cm tall, with square, downy, greyish stems. Leaves are opposite, oblong, wrinkled, grey-green and softly velvety, with a strong camphoraceous aroma. Violet-blue, two-lipped flowers are borne in whorled spikes.[11]
Habitat
Native to the Mediterranean, Europe and temperate Asia and widely naturalised elsewhere, growing on dry, sunny grassland, banks and scrubby hillsides, typically on calcareous soils.[11]
Native to the northern Mediterranean coast (particularly the Balkans and Italy), widely cultivated as a culinary and medicinal herb in gardens worldwide, preferring sunny, well-drained, often calcareous soils.[11]
Harvesting
Leaves are harvested throughout the growing season, ideally just before flowering, when essential-oil content is highest, and dried quickly in a warm, shaded place.[11]
Traditional Uses
Oregano has a long Mediterranean culinary-medicinal tradition as an aromatic digestive bitter and antiseptic remedy for coughs, colds and infections. Modern research on its carvacrol- and thymol-rich essential oil strongly supports broad antibacterial, antifungal and antioxidant activity, consistent with these traditional uses.[11, 12]
Sage has an ancient reputation - its Latin name 'salvia' derives from 'salvere', to be saved or healed - as a digestive, antiseptic and cognitive tonic. It has official European herbal-monograph use for dyspeptic complaints and excessive sweating, and as a gargle for inflammation of the mouth and throat; modern clinical trials support cognitive-enhancing effects in both healthy adults and people with dementia.[11, 12]
Preparations
Dried herb steeped in hot water as a digestive, aromatic tea.
The most-studied form; concentrated oil is a strong irritant and must be well diluted before topical use and never taken undiluted internally.
A small clinical study used an emulsified oregano oil preparation to clear enteric parasites and improve gut symptoms; oral use of concentrated oil should be supervised.
Dosage
Culinary amounts (as a food seasoning or mild tea) are considered safe; concentrated essential oil should only be used well diluted and is not intended for undiluted internal use without professional guidance. Educational reference only, not a prescription.
EMA herbal-monograph guidance suggests about 1-3 g dried leaf per cup as an infusion, up to three times daily for digestive complaints, or a stronger preparation used as a gargle. Avoid prolonged or high-dose (essential-oil) use given the neurotoxic thujone content, especially in pregnancy and epilepsy. Educational reference only, not a prescription.
