The ripe seeds of the Vitex have become a mainstay in modern herbalism, used to address a wide-range of conditions related to hormones. We had a Vitex bush for a few years before we realized its worth. It is a beautiful shrub with purple flowers and often called “Texas Lilac”. Now we grow four large shrubs.
Vitex (or Chaste Berry) is native to Mediterranean countries, and its uses were first developed in ancient Greece and Rome and were only slowly developed after the fall of these two empires. Most of its early uses were related to its spicy, warming nature in “dispelling wind”, although there are early references to its use in “inflammation of the womb”, and as an herb to “quench the passions”.

Benefits of Vitex for Wellness
Vitex has an long history of being useful for aiding many symptoms brought on by female hormonal imbalances. These include premenstrual syndrome, breast tenderness, and infertility.
No single constituent has been identified as accounting for vitex’s biological activity. The volatile components of the fruits of two varieties of Vitex (Agnus-castus) were obtained by hydrodistillation and identified by GC and GC-MS. Altogether 41 components were identified. The examined oils show a significant antibacterial activity. 
Vitex is a slow-acting herb. It is usually recommended to allow three full cycles for the plant to really work its magic, and many women take it for up to several years. In the thousands of years that it has been in use, there are no reports of even the mildest side effects. Vitex is a safe, gentle, and effective remedy, with something to offer women in every cycle of life.
Extract of the seeds of the plant Vitex (Agnus-castus) proven to be highly efficacious as a repellent against ticks, fleas, mosquitoes and biting flies. 
Vitex has been recommended by herbalists to reduce a man’s testosterone levels and to balance hormones in women. It is also used to suppress the onset of prostate cancer related to high testosterone levels.
Vitex has been used in the production of a drug for Mastalgia (sore breasts/tenderness) related to PMS and menopause. It’s considered that the extract of the chasteberry herb might help prevent excessive amounts of the hormone prolactin in the pituitary gland. High levels of this hormone might promote milk production in lactating and pregnant women, causing breast tenderness, and may also trigger unpredictable menstrual cycles and missed periods. Consequently, getting one 300mg of chasteberry extract capsule daily may be advantageous to lessen breast tenderness.
