Hormone Replacement Therapy vs. Natural Therapy For Menopause

This report is on Soy, Black Cohosh and Dong Quai, which are key ingredients in Melaleuca's EstrAval®.

Germany's Commission E, a governmental regulatory agency that studies and makes recommendations about medicinal herbs, has found black cohosh to be a safe and reasonably effective treatment of nervous conditions associated with menopause. Commission E is composed of scientists, toxicologists, physicians, and pharmacists and is considered to be the world authority on herbal medicines. Today in Germany, black cohosh is a main ingredient of three commercial drugs approved by Commission E and used for menopausal discomforts.

Black cohosh produces estrogen-like effects, but does not produce actual hormone activity. That means you receive health benefits without the risks associated with hormone therapy. In toxicology studies, no birth defect-inducing, mutagenic, or cancer-causing effects have been found with black cohosh extract. Long-term use appears to be safe.

Very large doses may cause nausea or dizziness. It may also prolong the hypnotic action of barbiturates. Black cohosh is not recommended for pregnant or nursing women. Anyone with heart disease should not use black cohosh.

Dong Quai should not be used during pregnancy and lactation. Also, hypersensitivity to the herb may lead to excessive bleeding and occasional fever. It may be photosensitizing and can cause a slight laxative effect. There is also a potential drug interaction with blood-thinning agents.

It is always recommended that you inform your health care practitioner if you are taking any over-the-counter medication or natural health products, as they can react adversely with some prescription drugs. The above cautions might not be a complete list of interactions. If you have a medical condition, especially, consult with your physician before taking these or any other herbs.

Dangers of Hormone Replacement Therapy
Due to an increased risk of invasive breast cancer, this July 9, 2002 press release from the National Heart, Lung and Blood Institute (NHLBI), NHLBI Stops Trial of Estrogen Plus Progestin Due to Increased Breast Cancer Risk, Lack of Overall Benefit, announced the halt of a major clinical trial being conducted by the Women's Health Initiative (WHI) on the risks and benefits of combined estrogen and progestin in healthy menopausal women. (The NHLBI plans, conducts, fosters, and supports an integrated and coordinated program of basic research, clinical investigations and trials, observational studies, and demonstration and education projects. Research is related to the causes, prevention, diagnosis, and treatment of heart, blood vessel, lung, and blood diseases; and sleep disorders.)

Results of the Women's Health Initiative Randomized Controlled Trial are detailed in the July 17, 2002 JAMA report (Journal of the American Medical Association) Risks and Benefits of Estrogen Plus Progestin in Healthy Postmenopausal Women. This report also references 43 related reports and medical abstracts.

Increased Risk of Ovarian Cancer is Linked to Estrogen Replacement Therapy was reported in this press release from the National Cancer Institute on July 16, 2002.

In this media advisory dated July 9, 2002, American Heart Association President Robert Bonow M.D. Responds to New Findings From Women's Health Initiative Trial, AHA President Robert Bonow, MD states that, "Based on current evidence, the American Heart Association advises that women do not start or continue combined HRT for the prevention of coronary heart disease."

Natural Alternatives to Hormone Replacement Therapy - EstrAval ®

The article, Natural Alternatives to Hormone Replacement Therapy, an article on the AHealthyMe web site, lists the benefits of black cohosh and donq quai, but cautions about the safety of many over-the-counter herbal cocktails and suggests seeking advice for using appropriate combinations. (The AHealthyMe website is produced by Blue Cross Blue Shield of Massachusetts and is a database of health articles and reference materials from respected medical journals and consumer publications.)

In this study were three groups of women, one using HRT alone, a second using a combination of HRT and supplements, and the third using supplements (soy, ginkgo biloba and black cohosh). Perceived quality of life and overall control of menopausal symptoms were highest among women using dietary supplements alone, with those using combination therapy second highest. Dietary supplement use among menopausal women attending a San Francisco health conference.

Menopause Support with Soy
In the article Menopause and Soy, Dr. Clare M. Hasler cites several studies on the efficacy of soy in menopausal women. (Dr. Clare M. Hasler received her B.S. in Human Nutrition from Michigan State University in 1981 and M.S. in Nutrition Science from The Pennsylvania State University in 1984. In 1990, she was awarded a dual Ph.D. in Environmental Toxicology and Human Nutrition from Michigan State University. From 1990-1992, Dr. Hasler was a postdoctoral fellow in the Laboratory of Cellular Carcinogenesis and Tumor Promotion at the National Cancer Institute, National Institutes of Health, Bethesda, MD. Her current research activities are focused on the role of soy in chronic disease prevention. She teaches courses at both the undergraduate and graduate level on functional foods and the role of phytochemicals in disease prevention. Dr. Hasler writes extensively on functional foods and is a widely requested speaker on the topic by industry, academia and the media. She was recently recognized by Self magazine as one of the "Top 25 Food Influentials".)
