Vitex (Vitex agnus-castus) or Chasteberry is derived from the fruit of the Mediterranean chaste tree.
Its name comes from the ancient Greeks and Romans because they believed that it decreased the female libido, thus ensuring chastity. It has been eaten and worn by Monks to promote celibacy. Its modern medicinal uses are also related to sex hormones because it works by lowering prolactin levels; thus, influencing proestrogen and estrogen. It's often used to regulate menstrual cycles, treat acne, and reduce breast tenderness. Read on to learn more about the uses of Vitex and if it's right for you.
Key Health Benefits of Vitex
The active ingredients of chaste tree have been noted to affect the pituitary gland. This gland is located in the brain and produces hormones that stimulate the production of sex hormones in other areas of the body.
It also contains chemicals that have the ability to stimulate human progesterone receptors and favour the production of luteinizing hormone over follicle-stimulating hormone. These hormones are used in the female body to support pregnancy and lactation, but their effects can also help other female complaints.
Natural health practitioners recommended chaste tree for conditions such as PMS, acne and menstrual cramps; hot flashes, vaginal dryness and other menopausal symptoms; insufficient milk production and first-trimester miscarriages.
Vitex Supplement Varieties
Chaste tree can be purchased as a loose herb, tincture or encapsulated herb. Better quality supplements are standardized, which is an assurance that the product contains chaste tree and has some active properties. The berry contains the greatest concentration of active ingredients.
Important Information
Although natural health practitioners sometimes recommend it to pregnant women, chaste tree may induce menstruation and should be used cautiously. It may alter hormonal cycles and theoretically can interfere with birth control pills and hormone replacement therapy. It alters dopamine levels and may affect drugs for seizures, Parkinson’s and mental disorders.
It's interesting how vitex has been shown to have progesterone receptor stimulating effects given that in the days of the ancient Greeks and Romans was believed to decrease female libido & was regarded by the monks as being something to promote celibacy...this feels like an example of the ancients!! (I know that celibacy and pregnancy/PMS support are very different but still it stands that the ancients had some iea that vitex/chaste tree has a hormonal effect and just having figured that out alone without modern science is really cool). Also, I find it cool that both the leaves and the fruit can be used for therapeutic effects: which one is more potent? Finally, its interesting that this herb effects dopamine too-clearly pretty complex what's going on here!!
