Description

Wild oregano grows on dry, lime-rich Mediterranean slopes and only fully develops its pungent, spicy aroma once the flowering herb, gathered in July and August, is dried. Carvacrol and thymol in the essential oil are responsible for its characteristic scent, complemented by rosmarinic acid, tannins and triterpene acids. As a spice it flavours Mediterranean dishes, while as tea or tincture it is traditionally credited with supporting digestion and respiratory infections; externally, the essential oil is used for inhalation during colds. Concentrated oregano oil strongly irritates skin and mucous membranes and must never be applied undiluted — a dilution of at least 1:10 in a fixed carrier oil is required. High internal doses can cause nausea, vomiting and gastric irritation. Because of its traditionally ascribed emmenagogue effect, therapeutic doses should be avoided during pregnancy.

  • TeaAerial partsInternalTraditional use

    Traditional folk-medicinal use as an aromatic infusion for dyspeptic complaints (bloating, flatulence, loss of appetite) and for catarrhal upper-respiratory complaints such as irritable cough and incipient bronchitis. The active principle is the carvacrol-rich essential oil with digestive, spasmolytic and secretolytic effects.

    Preparation & dosage

    Pour 150 ml boiling water over 1-2 g dried oregano herb, cover and infuse for 10 minutes, then strain. Drink a fresh cup two to three times daily between meals.

  • TinctureAerial partsInternalFolk medicine

    Folk-medicinal ethanolic tincture of the flowering herb for dyspeptic complaints, cramp-like stomach pain and productive bronchial catarrh. Ethanol preserves the volatile carvacrol-/thymol-containing essential oil and rosmarinic acid better than an aqueous infusion.

    Preparation & dosage

    1:5 tincture in 70 % ethanol from dried oregano herb. Usual daily dose: 20-40 drops (1-2 ml) three times daily in a little water before meals. Avoid in pregnancy.

  • Essential oilAerial partsExternalTraditional use

    Oregano essential oil (Oleum origani) is traditionally used for its antimicrobial properties due to its high carvacrol and thymol content — applied diluted as a rub for cold complaints or as an additive for inhalations. Strongly skin-irritating when undiluted; always dilute in a fixed carrier oil.

    Preparation & dosage

    Dilute 1-3 drops oregano essential oil in 10 ml almond or olive oil and rub onto chest/back. Not undiluted on the skin, not in the eyes, not for internal use without professional guidance.

    Liquid amount
    0.050.15 ml
    Doses per day
    2×

    Age restriction: ≥ 4 years — Oregano essential oil must not be used in infants and children under 4 years due to carvacrol/thymol content — risk of mucous-membrane irritation and laryngospasm with facial application.

  • InhalationAerial partsExternalFolk medicine

    Folk-medicinal steam inhalation of oregano herb or a few drops of diluted oregano essential oil for stubborn bronchial mucus, rhinitis and incipient bronchitis. The secretolytic action of carvacrol and thymol loosens viscous mucus.

    Preparation & dosage

    Pour 1 L hot (not boiling) water over a handful (5-10 g) of dried oregano herb, cover head with a towel, close eyes and inhale steam for 5-10 minutes. Alternatively add 2-3 drops oregano oil to 500 ml hot water.

    Dry amount
    510 g
    Doses per day
    2×

    Age restriction: ≥ 4 years — Inhalation with oregano oil not for children under 4 years due to carvacrol/thymol content — laryngospasm risk.
