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]
