Marjoram Essential Oil is steam distilled from the Thymus mastichina plant, which has a hairy stem, oval leaves and little whitish flowers in clusters. The entire plant exudes a strong aroma. This oil is said to be more effective than that of sweet marjoram when used as an expectorant for respiratory tract infections and spasms, as it has antiseptic properties for the upper respiratory tract, but is not a muscle relaxant or a sedative, as sweet marjoram is.
