Chaste berry contains several different constituents, including flavonoids, iridoid glycosides, and terpenoids. Chaste berry does not contain hormones. The benefits of chaste berry stem from its actions upon the pituitary gland. Chaste berry keeps prolactin secretion in check. The ability to decrease mildly elevated prolactin levels may benefit some women with breast tenderness associated with PMS. Chaste berry may also be helpful in menopause.

Benefits of the herb and
extract
The benefits of chaste berry stem from its actions upon the pituitary gland. Chaste berry
keeps prolactin secretion in check. The ability to decrease mildly elevated prolactin
levels may benefit some women with breast tenderness associated with
PMS.
Chaste berry may also be helpful in
menopause.
Chaste berry:
The PMS relief herb
PMS (premenstrual syndrome) is the name of a group of symptoms that start 7
to 14 days before a period and stop soon after the period begins. Most women feel some
discomfort before their periods but those with PMS may feel so anxious, depressed or
uncomfortable that they can't cope at home or at work. Some of the symptoms include a
bloated abdomen, feeling tired and tense, headache, tender and swollen breasts, and
wanting to be alone.
PMS seems to be linked in part to changes in
hormone levels during the menstrual cycle, and perhaps partly due to elevated levels of a
pituitary hormone called prolactin.
Several studies over the past few years have
indicated that extracts from chaste berry (the fruit of a small Eurasian tree, also called Vitex agnus) help with symptoms of PMS. In a recent study done in Germany, 86 patients
with PMS were treated daily with one tablet (20 mg chaste berry extract) during three menstrual cycles.
At the end of the study, many PMS-related symptoms were significantly reduced by treatment
with chaste berry in the majority of the participants. No serious adverse effects were reported. The
researchers say, "Extract of chaste berry is an effective and well
tolerated treatment for the relief of symptoms of the premenstrual syndrome."
How chaste berry works is not clear, but one
possibility is that it may reduce the release of prolactin from the pituitary gland.
At least two previous studies have also shown
the beneficial effects of chaste berry in relation to PMS. Other natural therapies that
could be helpful include exercise, yoga, B vitamins, calcium supplements, and reduction of
simple sugars, alcohol and caffeine.
Hormone replacement therapy and menopause
Recent studies indicate that long term replacement with Premarin (horse
derived estrogens) and synthetic progesterone increases the risk for heart disease,
cancer, blood clots and gallbladder disease.
The field of hormone or herbal therapy during or after menopause is very
complicated and there is no consensus within the medical community regarding the
best option for long term therapy. The medical community seems to be shifting
its viewpoint on hormone replacement. It appears that most traditional doctors
now prefer using low doses of hormones for a brief period of time to treat
menopausal symptoms, but prefer not to continue hormone replacement therapy indefinitely as in the past.

Fluoxetine versus Vitex agnus castus extract (chaste
berry )
in the treatment of premenstrual dysphoric disorder.
Hum Psychopharmacol. 2003 Apr;18(3):191-5.

Clinical trials have demonstrated that serotonin reuptake inhibitors (SRIs) and
the extract of chaste berry are effective for the treatment of
premenstrual dysphoric disorder (PMDD). However, to the best of our knowledge,
there has been no study comparing the efficacy of the SRIs with chaste berry extract. Therefore, the aim of the present study was to compare the
efficacy of fluoxetine, a selective serotonin reuptake inhibitor (SSRI), with
that of the chaste berry extract, a natural choice. After a period of 2 screening months
to screen the patients for suitability, 41 patients with PMDD according to
DSM-IV were recruited into the study. The patients were randomized to fluoxetine
or chaste berry for 2 months of single-blind, rater- blinded and prospective treatment
period. The outcome measures included the Penn daily symptom report (DSR), the
Hamilton depression rating scale (HAM-D), and the clinical global
impression-severity of illness (CGI-SI) and -improvement (CGI-I) scales. At
endpoint, using the clinical criterion for improvement, a similar percentage of
patients responded to fluoxetine (68%) and chaste berry (57). There
was no statistically significant difference between the groups with respect to
the rate of responders. This preliminary study suggests that patients with PMDD
respond well to treatment with both fluoxetine and chaste berry. However, fluoxetine was
more effective for psychological symptoms while the extract diminished the
physical symptoms.
Evaluation of estrogenic activity of plant extracts for the potential
treatment of menopausal symptoms.
J Agric Food Chem 2001 May;49(5):2472-9

Eight botanical preparations that are commonly used for the treatment of menopausal
symptoms were tested for estrogenic activity. Methanol extracts of red clover (Trifolium
pratense L.), chaste berry (Vitex agnus-castus L.), and hops (Humulus
lupulus L.) showed significant competitive binding to estrogen receptors alpha (ER alpha)
and beta (ER beta). With cultured Ishikawa (endometrial) cells, red clover and hops
exhibited estrogenic activity as indicated by induction of alkaline phosphatase (AP)
activity and up-regulation of progesterone receptor (PR) mRNA. Chasteberry also stimulated
PR expression, but no induction of AP activity was observed. In S30 breast cancer cells,
pS2 (presenelin-2), another estrogen-inducible gene, was up-regulated in the presence of
red clover, hops, and chasteberry. Interestingly, extracts of Asian ginseng (Panax ginseng
C.A. Meyer) and North American ginseng (Panax quinquefolius L.) induced pS2 mRNA
expression in S30 cells, but no significant ER binding affinity, AP induction, or PR
expression was noted in Ishikawa cells. Dong quai [Angelica sinensis (Oliv.) Diels] and
licorice (Glycyrrhiza glabra L.) showed only weak ER binding and PR and pS2 mRNA
induction. Black cohosh [Cimicifuga racemosa (L.) Nutt.] showed no activity in any of the
above in vitro assays. Bioassay-guided isolation utilizing ER competitive binding as a
monitor and screening using ultrafiltration LC-MS revealed that genistein was the most
active component of red clover. Consistent with this observation, genistein was found to
be the most effective of four red clover isoflavones tested in the above in vitro assays.
Therefore, estrogenic components of plant extracts can be identified using assays for
estrogenic activity along with screening and identification of the active components using
ultrafiltration LC-MS. These data suggest a potential use for some dietary supplements,
ingested by human beings, in the treatment of menopausal symptoms.
Chaste berry extract
supplement questions
Q. Can a chaste berry supplement be taken the same day as a
5-HTP supplement?
A. Probably, especially in low dosages, but each person may react
differently. Chaste berry is a safe supplement.
Q. I take chaste berry herb for menopause
symptoms and would like to supplement with
tongkat ali as an aphrodisiac and was wondering if there were obvious side
effects with the combination.
A. Chaste berry extract is mild in its effects compared to the
aphrodisiac herb but we don't foresee any problems from the chaste berry itself.
Q. Is chaste berry herb safe to take long term for several years for menopause
symptoms?
A. We often suggest to take a day off a week from a particular
herb, and a week of each month or every other month. This way, any long term
problems could be minimized. Many of these herbs, including chaste berry, have
not been studied long term.
How long should one take chasteberry supplement for
PMS or menopause alternative
therapy before deciding if it is not working?
We would suggest trying this herb for two months.
I take
tribulus terrestris
extract
for sex boosting and was wondering if
chaste berry used as an alternative
treatment for menopause would be interfered with the use of this aphrodisiac
herb.
We have not seen any studies that point to an interference, but
we suggest you take them alone for a week before mixing them the same day.
How good is the research for PMS and menopause with chaste berry
as a natural treatment?
Study results have been mixed with some menopause natural treatment
trials showing positive results whereas others have not shown this herb to have
a benefit beyond a placebo effect.
