The effectiveness for the claimed uses is not sufficiently documented. A positive contribution in combinations for "dyspeptic disorders," "liver and gall preparations," for "colds" and for diseases of the urogenital tract, for diabetes, as a tonic, as a tea for the stimulation of milk secretion and for bruises and similar conditions, cannot be determined.
Marjoram herb contains arbutin and hydroxyquinone in low concentrations. Therefore, the herb is not suited for extended use. Hydroxyquinone is carcinogenic as tested in animals. Topical application of hydroxyquinone leads to depigmentation of the skin. There are no reports of similar side effects with marjoram ointment.
Since the effectiveness for the claimed applications is not sufficiently documented, a therapeutic administration of marjoram herb cannot be recommended.
Considering that the risks are not sufficiently clarified, a topical use of ointments containing marjoram extracts should not be used for the claimed indications in infants and small children.
