Herb of the Day

Hyssop

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.

Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to hyssop, any of its constituents or any related plants in the Lamiaceae family.

Side Effects and Warnings

Hyssop has been reported to cause vomiting and seizures, especially at high doses. The essential oil contains the ketone pino-camphone, which is known to cause convulsions. Avoid in patients with epilepsy, fever, hypertension (high blood pressure) or pregnancy.

Pregnancy and Breastfeeding

Hyssop is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
