Hyssop belongs to the genus Hyssopus and it is a member of the mint family Lamiaceae. It has many synonyms including Hyssopus alopecuroides, H.angustifolia and H.hirsutus. It is a plant native to the Mediterranean region and to parts of the Middle East.  It has ,however, been introduced to many countries as a garden plant {see below} and has escaped over the wall to become naturalized in some of them ,particularly in central Europe. It is a species resistant to drought and thrives in dry rocky places in its native range.

Hyssop medicinal and other uses.

The name Hyssop derives from the Greek azab which indicates a holy herb, for it was employed to cleanse holy places. The plant has long been used in herbal medicine,and has Expectorant, diaphoretic {causes sweating}, stimulant, pectoral and carminative properties.

The main healing virtue seem to derive from the volatile oil. Mrs Greaves in her famous book 'Modern Herbal' states that " it admirably  promotes expectoration and in chronic catarrh its diaphoretic and stimualnt properties combine to render it of especial value."

Long before Mrs Greaves's time, Culpeper , in the 1600's  wrote in his herbal " Hyssop is so well known to be grown in every garden that it is needless to describe it". He goes on to say  " It is an excellent herb for quincy or swelling in the throat,to wash and gargle with it, being boiled in figs. It helpeth the toothache when boiled with vinegar and gargled therewith. The hot vapours of the decoction taken by a funnel into the ears,easeth the inflammation  and singing noises of them"
