Vitex agnus-castus, also called Vitex,  Chaste Tree, Chasteberry, Abraham's Balm 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.
Confusion with Vitex on the part of early settlers in the West Indies may have given to Ricinus communis the name "Castor-oil plant". Or the name "castor oil" might have come from its use as a replacement for<unk> reum.
It has been long believed to be an anaphrodisiac but its effectiveness remains controversial.
