Habitat & Cultivation: 

Vitex known to help the female reproductive system is Native to European, Mediterranean, and Central Asian countries.

It has been naturalized in the southeastern United States.


Vitex has been used for centuries, with wide support from both practitioners and the general public primarily for its use for gynecological complaints. However, Vitex has broad sweeping use in traditional folk medicine where it was used as a diuretic, digestive, antifungal, anti-anxiety, early birth, stomach aches, aphrodisiac, anti-oestrus cycle effect, analgesic, emmenagogue antispasmodic, aperitif, soporific (sedative) action, mastopathies (breast issues), inhibition of prolactin synthesis, and inhibitor for dopamin D2 and opiod. The cultural history around this plant is also fascinating. In Thesmophoria, an ancient religious greek festival held in honour of the goddess Demeter and her daughter Persephone, the plant was associated with chastity, so the women who remained “chaste” during the religious festival used the plant to adorn themselves as well as made their beds up with the leaves on them to help the remain chaste. And according to greek mythology, Hera, the sister and wife of Zeus, was born under a chaste tree. The plants association with chastity was adopted in some christian ritual and is still used today in some regions of Italy when nuns walk paths strewn with Chaste tree blossoms.

Vitex is understood to support menstrual irregularities because it is believed to…

  • stimulate the pituitary -

  • which, releases LH -

  • which, mildly inhibits FSH -

  • this shifts the estrogen/progesterone balance (to favor progesterone) -

  • thereby having a corpus luteum-like effect


More simply, there ends up being an improvement in the progesterone levels (due to the series of events listed above) which helps regulate the menses. Also, Vitex decreases prolactin.

Typically, the fruit/ berry is used from the Vitex plant (Riccio & Zollinger, 2019). Zahid, Rizwani, & Ishape (2016) recommended dosage for vitex includes: 30-40 mg of the fruit extract per day or 40 drops of tincture per day.

Used in a decoction, bitter and pungent flavors, not my favorite.
