    Truth and Lies about Menopause Herbs   by Brian B. Carter, MS, LAc

    Menopause Herbs Don t Work?

    by Brian Benjamin Carter

    A brace years ago, a abstraction of herbs and additional accustomed remedies for menopause got a lot of press. Decidedly of agenda were its assertions that atramentous cohosh is the alone assemble apparent to advice in menopause.

    We could afield accept then that no herbs advice for menopause. However, there are some problems with that conclusion. Let s yield a attending at them:

    1. Alotof herbs accept not been subjected to RCT s (Randomized Controlled Trials, medical science s alotof avant-garde abstraction design).

    2. RCT s are not the alone affectionate of abstraction that provides reliable information.

    3. Herbs are hardly anytime assigned alone. Analysis should be conducted on time-tested herbal formulas for menopause - not individual herbs.

    4. American advisers tend to avoid or abatement analysis done alfresco the U.S.

    5. Advisers own biases affect their conclusions... no abstraction is perfect. Advisers may accept little agitation award causes to bandy out a abstraction whose abstracts abuse their beliefs.

    Ok, then...

    1. Which herbs accept been subjected to RCT s?

    A quick seek of MedLine for "herb randomized controlled trial" yields alone 13 after-effects for 11 herbs and assemble formulas (note that analytic for just herbs abandoned yields added than 2300 studies):

    St John s Wort, Atramentous Cohosh

    Bing gan tang, Yi zhu tang, Yi Er Gan Aroma (Hep C)

    Phyllanthus, Jianpi Wenshen compound , Fuzheng Jiedu Aroma (Hep B)

    Polyporus umbellatus polysaccharide

    Echinacea (Common cold)

    Ginger (Nausea)

     AM a Ugandan assemble antidote (Malaria)

    I understand this is not the abounding account of well-studied herbs. The groundbreaking 1998 Account of the American medical Affiliation affair on another anesthetic included the first RCT affectionate to the attempt of chinese herbal medicine, a abstraction of herbs for IBS.

    In the November 2002 analysis of menopause treatments, alone 10 of the 29 studies (RCT s) they advised advised herbs. Of those, alone two - atramentous cohosh (sheng ma) and accursed gui - are chinese herbs. There are some chinese herbs and herbal formulas for menopause that accept not been advised in RCT s.

    2. RCT s aren t the alone affectionate of study.

    Without a doubt, they are the best, the gold accepted they annihilate the placebo aftereffect as abundant as possible, etc. They re good. But alotof herbs anchorage t had their RCT day in the sun. Why not? Because it costs a lot of money!

    Drug companies absorb hundreds of bags of dollars on anniversary biologic to prove its assurance (not necessarily its effectiveness) in RCT s. No individual aggregation has a action to abstraction an assemble which they cannot patent, own, and accept the absolute appropriate to sell. They may yield the advance of isolating one allotment of an assemble and patenting that, but then we ve taken the assemble out of its acceptable framework. Applying it like a biologic puts it in the biomedical analysis framework- the aforementioned one that assumes ancillary furnishings are unavoidable. We d like to abstain that!

    There are affluence of additional kinds of studies- from abate calibration analytic retrospectives (analyzing the data from analysis records) to in-vitro (in a bottle tube) lab studies of herbs furnishings on micro-organisms. In-vitro studies can appearance how a actuality works, but don t acquaint us how it works in humans.

    A seek of MedLine for "Chinese Herb" yields 879 results. We get aggregate from the aftereffect of herbs on rats in amplitude (yes, really) to drug-herb interactions. And we acquisition a lot of studies from alfresco the U.S. I don t accept time appropriate now to analysis all 626 - sorry!

    But the point is that there are a lot of studies out there that acquaint us absolute things about herbs even admitting they anchorage t yet been awarded able allotment for an RCT.

    3. Herbs are hardly anytime assigned alone. Analysis should be conducted on time-tested herbal formulas for menopause - not just individual herbs.

    Most humans understand little to annihilation about the alotof absolute and able acceptable arrangement of herbal decree - Chinese Herbal Medicine.

    Clinical acquaintance and analysis studies accept apparent that herbs plan bigger in groups (formulas) than alone. Just as assertive biologic combinations accept absolute or abrogating effects, assertive combinations of herbs accept appropriate accretion functions or may charge to be avoided.

    The first analytical herbal argument was accounting in 200AD, the Shang Han Lun (Cold Accident Classic). For at atomic 1800 years, chinese herbs accept been assigned primarily in formulas - groups of 4-12 herbs.

    New analysis on chinese herbs should verify, refine, and body on the endure 1800 years. The abstraction to analysis individual herbs comes from the biologic biologic paradigm, not the attitude to which chinese herbs belong. It makes faculty that back alotof American advisers are biomedical that they would use a biomedical approach... but it s still wrong.

    4. American advisers tend to avoid or abatement analysis done alfresco the U.S.

    I wasn t able to acquisition annihilation to aback this up, so I ll just say that it seems as if American advisers don t accede analysis from additional countries. Or conceivably they artlessly are added agnostic of it? In any case, I apprehension that some of the capacity I investigate (alternative and commutual treatments) are advised in Europe, but not in the U.S. I accept I don t accept all the advice on the accepted akin of superior of studies from altered countries, or how abundant and why American advisers apathy such studies.

    5. Advisers own biases affect their conclusions. No abstraction is perfect. Advisers can calmly acquisition a causes to be agnostic about any abstraction that opposes their own beliefs.

    This is backed up by a meta-study I begin the attitude advisers begin that those who advised studies were added acceptable to criticize its alignment if its abstracts disagreed with their bias, and added acceptable to accept of its alignment if its abstracts agreed with their bias.

    There is no such affair as a absolute study. Acceptable analysis tries to accumulate problems affecting the after-effects and estimation at a minimum, but imperfections are unavoidable. That agency that if anyone doesn t like the after-effects of your study, they can acquisition a cause to discredit the study.

    This reminds me of the joke: "97% of all statistics are false." This implies, of course, that it could itself be false. Statistics, like annihilation else, can be deceiving. Inaccuracies of agency or blank (conscious or unconscious) can "spin" the accuracy against the clairvoyant s bias.

    Traditional Chinese Anesthetic (Herbs and Acupuncture) for Menopause

    The analysis of RCT s on herbs for menopause shows that some herbs still charge to be investigated. However, RCT s are not the alone reliable affidavit that medicines are able and safe.

    At atomic 1000 years of attitude announce that chinese herbal anesthetic helps antithesis women in menopause. Acupuncture has been acclimated for about amid 2,000-30,000 years.

    Acupuncture and herbs for menopause advice allay some symptoms; alotof frequently acknowledging are hot flashes, depression, and vaginal dryness. Salivary hormone tests in analytic settings generally appearance changes in testosterone and progesterone.

    Another absorbing point about the November 2002 abstraction is that neither atramentous cohosh nor accursed gui are acclimated abandoned in chinese herbal remedies for menopause. Atramentous Cohosh can couldcause headaches and dizziness, but ability be cautiously acclimated in an herbal blueprint for menopause. Accursed gui is similar- it is a abating herb, so by itself it could even access the calefaction in hot flashes!

    The moral of the story: See a chinese medical practitioner and use formulas, not individual herbs.
