Source-derived summary

Vitex agnus-castus (also called vitex, chaste tree / chastetree, chasteberry, Abraham's balm, lilac chastetree, or monk's pepper) is a plant 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 subtropical flowering plants. Vitex is a cross-pollinating plant, but its self-pollination has been recorded.

Theophrastus mentioned the shrub several times, as ágnos (ἄγνος) in Enquiry into Plants. It has been long believed to be an anaphrodisiac – leading to its name as "chaste tree" – but its effectiveness for such action remains unproven. The shrub was utilized for religious rituals in ancient Greece and among the Philistines in modern Palestine as well as other countries in the Levant region.

Etymology and common names

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 V. agnus-castus in basketry. Its macaronic specific name agnus-castus repeats "chaste" in both Greek and Latin; the small tree was considered to be sacred to the virginal goddess Hestia/Vesta. The most common names are "chaste tree", "vitex", and "monk's pepper".

Description

Vitex agnus-castus is widely cultivated in warm, temperate, and subtropical regions for its delicately textured, aromatic foliage and butterfly-attracting midsummer spikes of lavender flowers opening in late summer in cooler climates.

Editorial summary

“Vitex agnus-castus” enters the record as species of plant. Crown Archives preserves that source wording while asking what Vitex, agnus-castus and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 226-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Vitex, agnus-castus and species.
Editorial analysis

Why this record matters

“Vitex agnus-castus” is worth following because a concise public description often conceals a longer documentary argument. Here, Vitex, agnus-castus and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q259318. The Library of Congress control number is sh97008691. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
