Key Constituents
The volatile oil, dominated by terpinen-4-ol and cis-sabinene hydrate in true sweet marjoram, gives most of the antimicrobial and antioxidant activity.
Contribute to antioxidant and anti-inflammatory activity.
Phenolic monoterpenes responsible for the antimicrobial and expectorant actions.

Safety, Cautions & Contraindications
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.
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).
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.
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).

Botanical Description
Tender perennial subshrub (Lamiaceae), often grown as an annual in cold climates, 20-60 cm tall, with square, downy, much-branched stems. Leaves are opposite, small, grey-green and ovate. Tiny white to pale pink, two-lipped flowers are borne in distinctive knot-like clustered spikes, the origin of the common name 'knotted marjoram'.[6]
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]
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]
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]
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
Dried herb infused in hot water as a traditional cough, cold and digestive tea.
Infusion used as a gargle for sore throat, drawing on the antiseptic essential oil constituents.
Standardized fluid extract, often combined with ivy leaf, the form studied in clinical trials for acute bronchitis.
Dosage
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.
