The use of plants for healing purposes have been predated long before the existence of  modern medicine. Herbal plants have formed a fundamental sources for conventional medicine in discovery of single ingredient medication, including aspirin (from willow bark), quinine (from cinchona bark), and morphine (from the opium poppy)......

Chaste tree berry is a species of Vitex agnus-castus, genus Vitex, belonging to the family Lamiaceae, native to the Mediterranean region, used in herbal medicine for thousands of year as anaphrodisiac herb and considered as Queen herb in treating menstrual problems and discomforts.

Hyperprolactinemia is a condition of elevated serum of  prolactine which is the hormone in regulated
breast development and lactation during puberty and pregnancy, respectively.

High levels of procltine has been found to associate to elevated symptoms in premenstrual syndrome women. Administration of herbal Chaste tree berry may ease the symptoms and treatment of in mild and serve cases of PMS.

According to the Second Military Medical University, in the induced hyperprolactinemia SD rat models by administration of metoclopramide dihydrochloride (50 mg/kg, tid, ip, for 10 d), injection of casticin, a flavonoid isolated from Vitex rotundifolia in treatment group, exhibited the reduction of (10, 20, and 40 mg/kg, ip, for 7 d) serum prolactin levels by 33.9%, 54.3%, and 64.7%,.compared untreated control group.

Dr. YE Q, the lead author in the study said, casticin ameliorated the stimulation of pituitary cells with 17β-Estradiol (E2), a female sex hormone in prolactin secretion..

The study also found that casticin at doses of 0.1, 1, and 10 micromol/L, significantly inhibited the prolactin release stimulated by 17β-Estradiol (E2) in a concentration-dependent manner., through regulating the DNA expression of estrogen receptors in activated sex hormone for secretion of porclatin.

In the review of pharmacology and clinical indications of the effectiveness of chaste tree berry in PMS women. the University of Göttingen found that
1. The herbal extract consisted a beneficially influence in most common premenstrual symptoms, indicated by a double-blind placebo-controlled studies.
2. Numerous less rigidly controlled studies indicated that AC extracts reduced premenstrual mastodynia through inhibiting levels of proclatin through suppressed the stimulation of the mammary gland in response to stressful situations and during deep sleep phases.

Dr. Wuttke W said" The search for the chemical identity of the dopaminergic compounds resulted in isolation of a number of diterpenes of which some clerodadienols were most important for the prolactin-suppressive effects" and "dopaminergic compounds present in Vitex agnus castus are clinically the important compounds which improve premenstrual mastodynia and possibly also other symptoms of the premenstrual syndrome".

Taking together, Chaste tree berry may be beneficiary in reduced symptoms for women with PMS during the menstrual cycle, especially in hyperprolactinemia induced premenstrual breast pain and discomfort.
