Vitex agnus-castus, also called vitex, chaste tree, chasteberry, Abraham's balm, lilac chastetree, or monk's pepper, is a native of the Mediterranean region. It is one of the few temperate-zone species of Vitex, which is on the whole a genus of tropical and sub-tropical flowering plants. Theophrastus mentioned the shrub several times, as agnos (άγνος) in Enquiry into Plants. Vitex, its name in Pliny the Elder, is derived from the Latin vieo, meaning to weave or to tie up, a reference to the use of Vitex agnus-castus in basketry. Its macaronic specific name repeats "chaste" in both Greek and Latin, and considered to be sacred to the goddess Hestia/Vesta.
