The use of hyssop as an herbal remedy dates back to Biblical times. It is mentioned in both the Old and New Testaments of the Christian Bible as a cleansing agent (although these references may be to other species of hyssop, such as Origanum aegypticum or Origanum syriacum, rather than Hyssopus officinalis).
Hyssop has been prescribed for a multitude of medical conditions, although there are few high-quality human trials researching these uses. It has been used traditionally as an antispasmodic, expectorant, emmenagogue (stimulates menstruation), stimulant, carminative (digestive aid), peripheral vasodilator, anti-inflammatory, anticatarrhal, antispasmodic, tonic and sweat-inducer. However, both the alcoholic extract and decoction have been used to inhibit sweating. Hyssop is used specifically for cough, bronchitis and chronic catarrh, and also for its tonic effects on the digestive, urinary, nervous and bronchial systems. Hot hyssop decoction vapors have also been used to treat inflammation and tinnitus.
