Chaste tree berry grows in the Eastern Mediterranean and is often referred to as 'vitex,' a portion of its scientific name. Chaste tree berry can be found in the more temperate parts of Africa. It bears brightly-colored purple flowers and a peppery fruit, which has been used traditionally for thousands of years. The leaves of the chaste tree have also been used traditionally, however, to a much lesser extent than the berries. The traditional use of the chaste tree berry can be traced as far back as the time of the ancient Greek physician Dioscorides. Originally, chaste tree berries were believed to help soldier's wives remain faithful while their husbands were away at battle, but no modern research has been able to conclude or suggest that chaste tree berry actually does decrease libido. Chaste tree was used historically by both men and women in ancient Greece and Rome and even by monks in the Middle Ages as a way to encourage chastity.
