Prospective Case Series on the Effects of Lumbosacral Manipulation on Dysmenorrhea
J Manipulative Physiol Ther 2008 (Mar); 31 (3): 237–246 ~ FULL TEXT
This prospective case series suggests the possibility that menstrual pain associated with primary dysmenorrhea may be alleviated by treating motion segment restrictions of the lumbosacral spine with a drop table technique. The research team needs to conduct a well-designed feasibility trial to further evaluate the effectiveness of this specific spinal manipulative technique for primary dysmenorrhea.
Ease Into Menopause Naturally
“Choice” is a concept closely associated with the generation of women now making their way through menopause. It is a concept that throughout most of their lives has motivated, bitterly divided and most of all conditioned these women to question the status quo--from civil rights to reproductive rights. So it comes as no surprise that when the vanguard of this generation experienced the onset of menopause and discovered that easing their symptoms meant choosing among their hearts, bones and breasts, they demanded more--more research, more guarantees, more choice in menopausal management options.
Estrogen's Two-Way Street
The continuing controversy over the health benefits and risks of estrogen is a complex and evolving story. Part of the reason is because estrogen is a much more complicated substance than originally believed. Although most people think of estrogen as a single entity, these hormones are actually three biochemically distinct molecules the body produces naturallyestrone (E1), estradiol (E2), and estriol (E3). These three estrogen molecules have different activities that make them more or less "estrogenic." The estrogenic activity often determines the mutagenic or carcinogenic potential of an estrogen.
Understanding Premenstrual Syndrome
Statistics today indicate that as many as 30 percent to 40 percent of menstruating women commonly experience some symptoms of PMS during the premenstrual period. In recent years it has been observed that PMS symptoms occur in definable clusters, leading to four distinct medical classifications.1 Most women experience one or a combination of these symptom clusters.
Menopause- Stopping The Symptoms Before They Stop You
Forty-five million women are menopausal in the United States today, and another 3.5 million women will become menopausal this year. Based on life expectancy trends, women face the prospect of spending the last one-third to one-half of their lives in a state of hormonal imbalance. The quality and quantity of life for these women will be determined by how well they (and their doctors) manage their hormone-replacement needs.
Hot Flashes: A Review of the Literature on Alternative and Complementary Treatment Approaches
Alternative Medicine Review 2003 (Aug); 8 (3): 284–302 ~ FULL TEXT
Hot flashes are a common experience for menopausal women, with an 85-percent incidence in the West. With the increased knowledge of side effects attributable to conventional treatment options, more women are exploring natural alternatives. Although more definitive research is necessary, several natural therapies show promise in treating hot flashes without the risks associated with conventional therapies. Soy and other phytoestrogens, black cohosh, evening primrose oil, vitamin E, the bioflavonoid hesperidin with vitamin C, ferulic acid, acupuncture treatment, and regular aerobic exercise have been shown effective in treating hot flashes in menopausal women.
Soy Isoflavones May Cut Menopausal Cardiovascular Risk
A woman's body goes through many changes during menopause—some of them with potential to affect cardiovascular health. When women's estrogen levels decrease during menopause, blood vessels can become rigid and less responsive to changes in blood flow and blood flow-altering mediators such as nitric oxide. Until now this decline in cardiovascular health was a risk women had to face if they opted against hormone replacement therapy. But research published in the March issue of The Journal of Clinical Endocrinology and Metabolism [1999;84(3):895-8] suggests that Promensil, an isoflavone-based dietary supplement derived from red clover, may help women maintain blood vessel elasticity and prevent hypertension during menopause.
Natural Menopausal Treatments: What's Hot, What's Not
The growing interest in natural menopausal treatments is partly because standard synthetic hormone replacement therapy has been linked to symptoms such as vaginal bleeding, bloating, and breast tenderness, as well as higher risks of breast and endometrial cancers. And although the scientific proof backing alternative treatments is not yet as extensive as it is on HRT, there is considerable evidence that natural remedies can indeed reduce the number and intensity of symptoms, all with mild or no side effects.
Soy Isoflavones for Women's Health: Is Soy a Viable Alternative to Traditional Estrogen Hormone Replacement?
In April and May of 1998, newspaper headlines were buzzing with news of the latest cancer prevention pills. Two prescription drugs, tamoxifen and raloxifene, were found to reduce the risk of breast cancer. There were drawbacks to the pharmaceuticals, however, as there usually are: Tamoxifen increased the risk of endometrial cancer and pulmonary embolism (blood clots in the lungs), and raloxifene users were more likely to suffer from hot flashes and leg cramps.
Estrogen Replacements
This article discusses the three "natural" human estrogens (estrone, estradiol, and estriol), the so-called xenoestrogens (including "designer estrogens" like tamoxifen and raloxifene, and Pesticides and Herbicides, which also induce estrogenic properties in humans), and the Phytoestrogens (derived from red clover, soy and certain other legumes). It then discusses the safety of phytoestrogen replacement for hormonal balancing.

Efficacy of Black cohosh-containing Preparations
on Menopausal Symptoms: A Meta-analysis
Altern Ther Health Med. 2010 (Jan); 16 (1): 36–44
A systematic search of three databases (PubMed, Embase, and Cochrane library) was conducted to identify relevant literature. Two reviewers independently abstracted the data from the eligible studies. Of the 288 English language citations screened, nine randomized placebo-controlled trials were included. Among these trials, six demonstrated a significant improvement in the black cohosh group compared with the placebo group.
Black Cohosh
Efficacy of Black Cohosh
From Prescription for Health Newsletter - July
1999.
By Shari Lieberman
Several placebo controlled, randomized, multi-center trials show
that a black cohosh proprietary extract is effective in
alleviating menopausal symptoms. Studies have shown results with
black cohosh are equal to conventional hormone treatment therapy
with negligible side effects.
An issue has been raised concerning black cohosh's hormonal-like
activity. The German Commission E monograph describes no
contraindications with the herb. Many studies recommend its use
for menopausal women who are at risk for breast cancer or who
experience surgically or medically induced menopause. Several
studies have looked at black cohosh's effects on estrogen
receptors. Black Cohosh constituents have been shown to bind to
estrogen receptors in animal studies. However, human and animal
studies have shown they do not affect luteinizing hormone
levels.
Although effects on vaginal parameters have been suggested in
earlier studies, recent studies show black Cohosh does not
exhibit estrogen-like effects. A recent study showed the herbal
extract doesn't exert an estrogenic effect on the vagina and
uterus of ovariectomized rats and mice. Also, the Ames test
demonstrated no evidence of mutagenicity. Another toxicology
study gave extraordinarily high levels of black Cohosh to female
Wistar rats without any abnormalities reported.
An in vitro study was conducted with breast cancer cell lines to
determine Black Cohosh extract's effect on their proliferation.
(Estrogen will proliferate estrogen-receptor-positive breast
cancer cell lines.) A concentration-dependent proliferation
inhibition was observed for black Cohosh that may be interpreted
as an estrogen receptor blockade. In the presence of estradiol
and black Cohosh, the estrogen-induced stimulatory effects of
estradiol are inhibited by the herbal extract. When tamoxifen was
added to the breast cancer cell lines exposed to estrogen, it
significantly decreased cancer cell proliferation. However, the
inhibitory effects of tamoxifen and black Cohosh applied
simultaneously to breast cancer cells exposed to estrogen was
greater than the individual substances. This suggests black
Cohosh is a viable alternative for women who've had breast
cancer.
Recent studies reveal that women on estrogen replacement therapy (ERT) for five-plus years, with or with out progestin, have a 35 to 50 percent increased risk of breast cancer. Black cohosh
appears to be as effective --yet far safer-than conventional treatment for menopausal symptoms.
Black cohosh, or Cimicifuga racemosa, is a major component of
Shaklee Corporation's new product for relief of menopause related symptoms called Menopause Balance Complex*.
