Chaste tree (Vitex agnus-castus), also known as chasteberry, has a long history of traditional use in supporting reproductive health, particularly in women. Traditionally, it was believed to suppress libido, earning it the name "chaste tree," as it was used in monasteries to help monks remain celibate. However, in herbal medicine, it is often used to balance hormones, regulate menstrual cycles, and alleviate symptoms of premenstrual syndrome (PMS). While some traditional texts mention its use in addressing issues of low sex drive, especially when linked to hormonal imbalances, the emphasis historically has been more on its role in reducing sexual desire or supporting reproductive health more broadly rather than directly enhancing libido.

Scientific studies on chaste tree have focused primarily on its effects on hormonal balance, particularly prolactin levels, rather than directly on sexual desire or libido. There is limited clinical evidence to suggest that it can increase sex drive; most research supports its use for conditions like PMS, mastalgia, or irregular menstruation. Therefore, while tradition supports some use for low sex drive—mainly in contexts where hormonal imbalance is a contributing factor—the evidence is weak, and its reputation as a libido booster is not strongly supported by scientific research. For individuals with low sex drive due to hormonal issues, chaste tree may have some indirect benefit, but it is not a primary or well-established use of the herb.
