Black Cohosh (Cimicifuga Racemosa) as Treatment of Menopause-Related Symptoms: A Mini Review - Juniper publishers
Journal of Trends in Technical and Scientific Research
Abstract
Black cohosh belongs to the family Cimicifuga
racemosa. Root and rhizome are the medicinal parts of the herb. Black
cohosh is used against the treatment of Menopause symptoms (including
vasomotor); Premenstrual Syndrome (PMS); depression (mild); arthritis
and migraine. It is often used as an alternative to estrogen-based
replacement therapies to treat hot flushes that frequently accompany the
transition to menopause.

Introduction
Black cohosh belongs to the family Cimicifuga
racemosa. Root and rhizome are the medicinal parts of the herb. Black
cohosh is used against the treatment of Menopause symptoms (including
vasomotor); premenstrual syndrome; depression (mild); arthritis and
migraine [1-5]. It is often used as an alternative to estrogen-based
replacement therapies to treat hot flushes that frequently accompany the
transition to menopause [6,7]. However, definitive clinical data about
efficacy have been equivocal [8]. Trials conducted by Pockaj et al. [8]
found no evidence that black cohosh reduced hot flashes more than the
placebo. As a constituent to Avlimil (a dietary supplement advertised to
ameliorate female sexual dysfunction), black cohosh is suggested to
have estrogenic, anti-estrogenic, or androgenic potential for relieving
menopausal symptoms. Furthermore, DMSO extract of Avlimil was found to
increase cell proliferation and cytotoxicity in MCF-7 (in vitro) at low
and high concentrations, respectively Ju, et al. [9].
Materials and Methods
To accomplish the target on Black cohosh as treatment
of menopause related systems and associated adverse effects,
peer-reviewed English language articles published during 2 decades were
selected from Pub Med, Pub Med Central, Science di
rect, Up-to-date, Med Line, comprehensive data base, Cochrane library
and the internet (Google, Yahoo).
Chemical constituents
The main constituents of Black cohosh are
triterpenoids, phenolic compounds [9], phytoestrogens, isoflavones
cimicifugoside, formononetin and salicylic acid [10].
Toxicity
Black cohosh significantly increased the incidence of
lung metastases in tumor-bearing animals compared with mice fed the
isoflavone-free control diet [6], and is reported to cause liver
toxicity and induce micronuclei [11].
Contraindications
Contraindicated in individuals with a history of
estrogen-dependent tumors or endometrial cancer. Black cohosh may cause
nausea, vomiting, headache, and hypotension at higher dosages. Use with
caution in individuals allergic to salicylates; it is not known whether
the amount of salicylic acid is likely to affect platelet aggregation or
have other effects associated with salicylates. Use with caution in
individuals with hypotension or those taking antihypertensive
medications.
Use with caution in individuals receiving
anticoagulant medications. Monitoring of serum hormone levels is
recommended after 6 months of use with black cohosh. Use with caution in
inAbstractdividuals with liver disease due to cases of liver damage
[12-14].
Use with caution in patients with seizure disorder [15]. Contraindicated
in pregnancy (based on in vitro or animal studies, may
stimulate uterine contractions) and lactation [16].
To date, phytoestrogen-containing herbs have not been associated
with the negative health effects seen with synthetic estrogen.
However, use with caution in individuals on hormone replacement
therapy or oral contraceptives, or a history of thromboembolic
disease or stroke [17-21].
Theoretical interactions
Oral contraceptives, hormonal replacement therapy, NSAIDs,
anticoagulants, antihypertensives, drugs that lower the seizure
threshold, hepatoxic drugs; cytochrome P450, 3A4, and 2D6
substrates.
