Key Constituents

Essential oil (terpinen-4-ol, sabinene hydrate, thymol, carvacrol)[9]

The volatile oil, dominated by terpinen-4-ol and cis-sabinene hydrate in true sweet marjoram, gives most of the antimicrobial and antioxidant activity.

Rosmarinic acid and phenolic acids[6, 8]

Contribute to antioxidant and anti-inflammatory activity.

Safety, Cautions & Contraindications

Safety note[11, 12, 13]Caution

Generally very safe as a culinary herb. Essential oil should not be ingested in large amounts and avoided in pregnancy. Theoretically may interact with anticoagulants. Avoid medicinal doses during pregnancy.

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

Duke (2002) rates marjoram (Origanum majorana) as +++ and notes antiviral, antispasmodic, COX-2 inhibitory, and antiseptic activities at the experimental level (score 1). It demonstrates antiherpetic activity in vitro. The plant contains rosmarinic acid and thymol, which contribute to antioxidant and antimicrobial effects. Dose: 1–2 g dried herb as tea three times daily or equivalent preparations. Duke notes the plant is generally well-tolerated with no significant contraindications at usual herbal doses (Duke, 2002).

Safety note[12]Caution

Culinary amounts are safe. Thyme essential oil is a strong irritant - dilute well before any topical use and do not take the undiluted oil internally.

Safety note[11]Caution

A cough that persists beyond about a week, or with fever or breathlessness, needs medical assessment. Avoid medicinal/oil doses in pregnancy; allergy is possible in people sensitive to the mint family (Lamiaceae).

Flowering Period: July-September

Low, woody-based aromatic perennial subshrub with small, narrow, grey-green leaves and small, pale pink to lilac, two-lipped flowers borne in whorled clusters along the upper stems.[11]

Height: 15-40 cm
Habit: Low, woody-based, bushy aromatic perennial subshrub

Habitat

Native to Cyprus, Turkey and the eastern Mediterranean, and widely cultivated as a culinary and medicinal herb in gardens worldwide; prefers full sun and well-drained, often calcareous soils.[6]

Grows on dry, sunny, rocky, well-drained soils; native to the western Mediterranean and widely cultivated as a culinary and medicinal herb worldwide.[11]

Harvesting

The aerial flowering parts are cut just before or at flowering (summer), when essential-oil content is highest, and dried quickly in a warm, shaded, well-ventilated place.[9]

Parts: Leaf, Flower
Season: Summer, just before or at flowering

The flowering aerial parts are cut just as flowering begins, when essential oil content is highest, and dried in a warm, shaded, airy place; essential oil is obtained by steam distillation of the fresh or dried herb.[11]

Parts: Aerial parts (herb) and essential oil
Season: Late spring to summer, at the start of flowering

Traditional Uses

Marjoram has a long Mediterranean culinary-medicinal tradition as a digestive carminative and mild sedative for indigestion, cramping and poor sleep, and as an antiseptic for minor wounds and infections. Modern research confirms antispasmodic, antimicrobial, antioxidant and anti-inflammatory activity from its essential oil and phenolic constituents.[6, 8]

Thyme has a long Mediterranean and European tradition as an antimicrobial and expectorant remedy for coughs, bronchitis and sore throat, formalised in EU herbal monograph recognition, with a fixed thyme-ivy extract combination shown superior to placebo for acute bronchitis with productive cough in clinical trial.[11, 13]

Preparations

Infusion (tea)[11, 12, 13]

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

Essential oil (topical)[4]

Diluted essential oil applied for muscular aches or minor skin infections.

Infusion[11]

Dried herb infused in hot water as a traditional cough, cold and digestive tea.

Gargle[11]

Infusion used as a gargle for sore throat, drawing on the antiseptic essential oil constituents.

Standardized fluid extract (thyme-ivy combination)[13]

Standardized fluid extract, often combined with ivy leaf, the form studied in clinical trials for acute bronchitis.

Dosage

Infusion (tea)[11, 12, 13]

Duke (2002) suggests about 1-2 g dried herb as tea, three times daily, or equivalent preparations. Educational reference only, not a prescription; avoid medicinal doses in pregnancy.

Infusion[11]

The EU herbal monograph suggests around 1-2 g of dried herb per cup, up to three times daily. Educational reference only, not a prescription; do not take the essential oil undiluted internally.
