Oregano

Origanum vulgare

Family: Labiatae (Lamiaceae)  |  Parts Used: Leaf and flower

Oregano is a potent antimicrobial herb used in cooking and medicine across Western and Middle Eastern traditions. The essential oil is one of the strongest natural antiseptics available, containing high concentrations of carvacrol and thymol. Traditionally used for acute and chronic respiratory conditions, coughs, colds, and indigestion. The infused oil is applied directly for immune support at the onset of illness.

Bonnie's Notes

Oregano infused oil is my go-to when I feel an illness coming on. A drop or two under the tongue at the first sign of symptoms is my standard approach.

Cautions

  • Generally safe as a culinary herb. Oregano essential oil and infused oil are potent and must be diluted before topical use. Undiluted oil may cause gastrointestinal upset and skin irritation.
  • May interact with blood thinners and diabetes medications.
  • Not recommended in medicinal doses during pregnancy, as it may stimulate the uterus.
  • May cause allergic reactions in individuals sensitive to plants in the Lamiaceae family.

Habitat & Growing Conditions

Native to Europe, central Asia, and the Middle East. A perennial herb hardy to zone 5. Prefers well-drained soil and full sun. Widely naturalized in the Americas and grown as a culinary and medicinal herb globally.
