Safety, Cautions & Contraindications

Safety note[12]Info

The sesquiterpene lactones (especially alantolactone) are known skin sensitisers and can cause allergic contact dermatitis; people sensitive to the daisy family (Asteraceae) should be cautious.

Safety note[12]Caution

Large doses can cause nausea, vomiting and diarrhoea; safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.

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).

Botanical Description

Tall, robust perennial herb with large, coarse, hairy leaves - broadly oval near the base and progressively smaller up the stem - arising from a thick, aromatic rhizome. Large, shaggy, bright yellow daisy-like flower heads with numerous narrow ray florets are borne at the top of stout, branching stems.[12]

Height: 1-2.5 m
Habit: Tall, robust, coarse-leaved perennial herb
Leaves: Large, coarse, hairy, broadly oval near the base, smaller up the stem
Flowers: Large, shaggy, bright yellow daisy-like heads with numerous narrow ray florets
Stem: Stout, branching, hairy
Root: Thick, aromatic, branching rhizome (the medicinal part)
Fruit: Small achene with a pappus
Flowering Period: July-August

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

Habitat

Grows in damp meadows, pastures, roadsides and woodland margins on moist, rich soils; native to Europe and Western Asia and naturalised in North America.[12]

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]

Harvesting

The root and rhizome are dug in autumn of the second or later year, when sesquiterpene lactone and inulin content is highest, then cleaned, sliced and dried.[12]

Parts: Root and rhizome
Season: Autumn, from second-year or older plants

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

Traditional Uses

Elecampane root has a long European tradition, reflected in the old name 'elf dock', as a warming expectorant remedy for productive cough, bronchitis and chronic respiratory catarrh, and topically and internally as an antimicrobial for skin and wound infections.[12]

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]

Preparations

Decoction[12]

Dried root simmered in water as a traditional expectorant and antimicrobial tea.

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.
