Hyssop is used in treating lung ailments. The leaves are applied to wounds as a poultice to aid in healing. The tea is also used to soothe sore throats, both by drinking the tea and by gargling with it. It has been used to inhibit the growth of the herpes simplex virus. The essential oil, diluted and applied to the scalp, kills lice and cures itchy scalp caused by eczema and dandruff. Do not use if pregnant or suffering from epilepsy.
Hyssop prefers dry conditions, tolerates most soils, and full sun. It is a member of the mint family, and is a perennial shrubby plant growing to 3 feet tall. Plant it near your grapevines to help improve your crops, and near clematis to help them avoid insect infestations. Hyssop essential oil, used as a spray, (or the infusion) can treat plants that are affected by bacterial problems.
