Hyssop hyssopus officinalis
Blue Hyssop is an ornamental herb with large amounts of strikingly bright blue flowers and a lovely bushy growth habit. The leaves are said to have a slightly bitter, mint-like flavor, sometimes used in herbal teas. Blue Hyssop is not used for cooking but has a history of medicinal use; anti-inflammatory and anti-spasmodic properties are attributed to it.
In the gospel of John, 19:59, “They filled a sponge with vinegar, and put it upon hyssop, and put it into his mouth.” In I Kings 4:23 Solomon “spoke of trees, from the cedar tree that is in Lebanon even unto the hyssop that springeth out of the wall.”
Harvest flowering tops or whole herb in flower are harvested just as blooming begins (usually mid-summer). Tie in bunches and hang under shade to dry.
