Vitex agnus-castus Chaste Tree
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. It has been long believed to be an anaphrodisiac
but its effectiveness remains controversial.
