Hyssopus officinalis, also known as Herb Hyssop, is a herbaceous plant with antiseptic, cough-relieving, and expectorant properties. It is commonly used as an aromatic herb and medicinal plant in cooking and herbal medicine. Hyssop is a part of the mint family and is native to Southern Europe, Caucasus, Iran, and Turkey. The plant produces small flowers usually blue, but rarely pink, purple or white, and has a strongly aromatic flavor similar to a cross between sage and mint. Hyssop has been in use since classical antiquity, and its name is a direct adaptation from the Greek ὕσσωπος (hyssopos). Harvesting Hyssop twice yearly, it is a plant that thrives in full sun and warm climates and is tolerant of chalky, sandy soils. Hyssopus officinalis is used as a flavoring in soups, salads, and liqueurs, and its leaves are eaten raw. Its soothing, expectorant, and cough suppressant properties make it a favorite herb in traditional medicine. However, Hyssop oil can cause seizures and convulsions, especially in children. Harvested when the plant is flowering, the flowering tips are collected and used for the essential oil, which includes thujone and phenol. Its high concentrations of thujone and chemicals that stimulate the central nervous system can provoke epileptic reactions. Overall, Hyssopus officinalis is a plant with multiple uses and should be used with caution depending on the purpose of its use.
