Safety, Cautions & Contraindications

Safety note[12]Caution

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.

Safety note[11]Caution

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).

Safety note[11, 12, 13]Caution

Generally safe at culinary doses. Essential oil is highly concentrated and must be diluted before topical use; undiluted application can cause skin sensitisation. Not recommended internally during pregnancy (uterine stimulant effects possible). Phenol-rich thyme preparations should be avoided long-term in high doses. May potentiate anticoagulant medications.

Safety note[11, 12, 13, 14]Info

Duke (2002) rates Thymus vulgaris (garden thyme, closely related to breckland thyme) as +++ with clinical evidence (score 2) for antibacterial, bronchospasmolytic, and antispasmodic activities, consistent with Commission E and WHO approvals for bronchitis and upper respiratory catarrh. The primary active constituent is thymol, with carvacrol as a secondary compound. Dose: 1–2 g dried herb as tea three times daily. The plant demonstrates COX-2 inhibitory activity and calcium antagonism, which may explain its antispasmodic effects (Duke, 2002).

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]

Height: 20-80 cm
Habit: Bushy, aromatic perennial herb/subshrub
Leaves: Opposite, ovate, aromatic
Flowers: Small, purplish-pink (occasionally white), in dense corymb-like terminal clusters
Stem: Square, often reddish, downy
Root: Fibrous, spreading perennial rootstock
Fruit: Four small nutlets (typical Lamiaceae schizocarp)
Flowering Period: July-September

Low, mat-forming, aromatic perennial subshrub with tiny, oval, strongly aromatic leaves on trailing, wiry, hairy stems that root as they spread. Small, pinkish-purple, two-lipped flowers are borne in dense whorled clusters at the stem tips.

Height: 2-10 cm (mat-forming, trailing)
Habit: Low, mat-forming, aromatic perennial subshrub
Leaves: Tiny, oval, strongly aromatic
Flowers: Small, pinkish-purple, two-lipped, in dense whorled terminal clusters
Stem: Trailing, wiry, hairy, rooting as it spreads
Root: Fine, fibrous roots along the creeping stem
Fruit: Small nutlet
Flowering Period: May-September

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]

Grows on dry, sunny heath, grassland, rocky ground and sandy soils; native to Europe and widely distributed across the northern temperate zone.

Harvesting

Aerial parts are cut at or just before flowering (mid- to late summer), when essential-oil (carvacrol/thymol) content peaks, then dried quickly in the shade.[4, 9]

Parts: Aerial parts (leaf, herb)
Season: Mid- to late summer, at or just before flowering

The flowering aerial parts (flower and leaf) are cut at the start of flowering in summer and dried in a warm, shaded, airy place.

Parts: Flower, Leaf
Season: Summer, at start of flowering

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]

Wild thyme has a long European folk tradition, closely paralleling its relative garden thyme, as an antimicrobial and expectorant remedy for coughs and respiratory infections, a digestive/gastroprotective herb, and a topical antiseptic.[11, 12, 13]

Preparations

Infusion (tea)[11]

Dried herb steeped in hot water as a digestive, aromatic tea.

Essential oil (diluted, topical/aromatic)[12]

The most-studied form; concentrated oil is a strong irritant and must be well diluted before topical use and never taken undiluted internally.

Emulsified oil (oral, supervised)[13]

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.

Infusion[12]

Dried flowering herb infused in hot water as a traditional respiratory and digestive tea.

Dosage

Culinary/infusion use[12]

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.
