Marjoram

Marjoram essential oil

Sweet marjoram (Origanum majorana) essential oil is rich in oxygenated monoterpenes, principally terpinen-4-ol, sabinene hydrate, sabinene, gamma-terpinene, and linalool, which together account for its well-documented antimicrobial and biofilm-inhibitory properties.[1] In vitro studies on rat and rabbit smooth muscle confirm a direct myorelaxant (antispasmodic) effect, providing a mechanistic basis for its traditional use in relieving abdominal cramps and infantile colic.[2]

Marjoram Spanish (Thymus mastichina) is botanically a thyme species rather than a true Origanum, and its GC-MS profile reflects this: 1,8-cineole dominates at 50-61%, with linalool, alpha-pinene, beta-pinene and alpha-terpineol as secondary constituents, producing a far more camphoraceous, cineole-forward profile than sweet marjoram's terpinen-4-ol chemistry. Essential oils from wild Portuguese Thymus species sharing this cineole/linalool chemistry showed antimicrobial activity against E. coli, S. aureus and Candida albicans.[3]
