What is Chasteberry?
Chasteberry is a plant. It is also known as vitex or Monk's pepper. Because at one point Vitex was thought to lead to loss of libido, it has earned the nickname "chaste tree". This medicinal plant is native to the Mediterranean and Central Asia where it has a long history of use by herbal healers, including Hippocrates and Dioscorides. Ancient uses for chasteberry included birth control and suppression of libido, especially in monks. It grows to heights between 6 and 25 feet.  The fruit of the plant is primarily used and appears as tiny black peppercorns, possessing a pepper-like aroma and flavor. The leaves are occasionally used medicinally and appear as 2 - 6 inch long leaflets that are dark green above and gray underneath. Slender spikes of lavender/blue flowers are sometimes used in medicines as well. It contains several possibly active chemicals - most notably, some that affect Prolactin levels in the body. Chasteberry is believed to work by suppressing the release of Prolactin from the pituitary gland. For women who are not pregnant, high prolactin levels may be associated with breast pain and symptoms of premenstrual syndrome (PMS), such as bloating, cramps, irritability, and mood swings.
The main active compounds in Vitex/chasteberry are found in its ripe dried fruit, and its main constituents are the flavonoids, which include casticin (the predominant flavonoid), isovitexin, and orientin. It also contains terpenes and plant steroids. Supplement form of it is available in tablets, capsules, tinctures and liquid form.
