Hyssop ( Hyssopus officinalis). Hyssop has astringent, emmenagogue (stimulating menstrual flow), relaxant, diuretic, and wound-healing properties. It stimulates mucus production, and is helpful in soothing sore throats, and coughs. It has also been known to help against asthma. Because it also relaxes muscle, it is helpful in aiding digestive problems. Its antibacterial properties make hyssop a good vermifuge (expels intestinal parasites). Hyssop essential oil has medicinal properties, but has also been linked to epileptic seizures, and should be taken with precaution. Growth tips staff horticulturist Loddie Dolinski: This plant is pretty hardy and doesn’t need too much water. Once it’s been established it merely needs normal watering. It should be grown in full sun. Hyssop gets no pests after it’s grown.
