Agnus castus, commonly known as chaste tree or vitex, is a deciduous shrub or small tree native to the Mediterranean region and central Asia. The plant is renowned for its small, fragrant leaves and clusters of purple or white flowers. Agnus castus has been used in traditional medicine for centuries, particularly for its purported effects on hormonal balance and menstrual health. The name "agnus castus" translates to "chaste tree" in Latin, reflecting its historical use to promote chastity. In Hebrew, it is known as עץ התמימות (Etz HaTmimut). The plant's berries and leaves are often used to make supplements and teas, and it is sometimes referred to as monk's pepper due to its historical use by monks to suppress libido. Key compounds in Agnus castus, such as flavonoids and essential oils, are believed to interact with the pituitary gland, influencing hormone production. The plant is also cultivated for ornamental purposes and is known by various names in other languages, including Vitex agnus-castus in scientific terminology and Keuschlamm in German.
