The study of medicinal plants has many unique challenges and special considerations. These plants are studied for their specific chemistry, or
pharmacologic activity. Plants are highly sensitive to their environment and respond through changes in their chemistry. To date, one of the biggest
problems in the study of medicinal plants has been the acquisition of consistent, positively identified material for chemical analysis. Successful
protocols for the collection, identification, and establishment of medicinal plants species in tissue culture is invaluable for future studies. This protocol
outlines methods to establish Scutellaria baicalenisis, and Scutellaria lateriflora from commercial seed sources, and collection and establishment of
Scutellaria racemosa from wild populations.

In 2003, semi-structured interviews were conducted in British Columbia, Canada with participants obtained using a purposive sample on the
ethnoveterinary remedies used for animals. Twenty-nine participants provided the information in this paper on the ethnoveterinary remedies used for
reproductive health in dogs and cats. The plants used for pregnancy support and milk production in pets were raspberry-leaf (Rubus idaeus),
motherwort (Leonurus cardiaca), flaxseed (Linum usitatissimum) and ginger (Zingiber officinale). Uterine infections were treated with black cohosh
(Actaea racemosa) and goldenseal (Hydrastis canadensis). Most of the studies conducted on these plants have not been conducted on companion

OBJECTIVES: This review presents findings with clear statements from the literature as well as own results of effects of soy, red clover
and their isoflavones as well as of the Cimicifuga racemosa extract BNO 1055. Experimental and clinical effects on climacteric complaints,
osteoprotective effects, activity in the urogenital tract, and risks concerning cardiovascular diseases and mammary and endometrial tissue will
be compared, also in comparison to classical hormone preparations. The question whether soy and red clover products and/or Cimicifuga
racemosa (CR) preparations are endocrine disrupters or may fulfill the criteria of the so-called phyto-SERMs will be discussed.
METHODS: Review of selected publications since 1980 and summary of unpublished own results of the authors. RESULTS: Experimental and
clinical evidences suggest that soy/red clover and their isoflavones do not fulfill the criteria of an ideal SERM. They appear to have mild
osteoprotective effects but do not improve climacteric complaints. Furthermore, they seem to stimulate uterine growth and mammary
epithelial proliferation. In ovariectomized rats, the CR extract BNO 1055 showed many of the beneficial effects of 17beta-estradiol, including
effects in the brain/hypothalamus to reduce serum LH levels, effects in the bone to prevent osteoporosis and estrogenic effects in the urinary bladder. The CR extract BNO 1055 had no uterotrophic effect. CONCLUSION: If clinical studies confirm these results, the Cimicifuga racemosa
preparation BNO 1055 would appear as an ideal SERM and may therefore be an alternative to hormone replacement therapy.

In spite of the fact that severe side effects have been reported, black cohosh [Actaea racemosa (syn. Cimifuga racemosa)] is likely to be one of the
most popular herbs used in the treatment of postmenopausal symptoms and menstrual dysfunction. We report the cases of two patients, one with
submassive liver necrosis and the other with chronic hepatitis most likely related to the use of two different preparations containing black cohosh.
This represents another advice for caution concerning this popular preparation of inconsistent therapeutic value.

BACKGROUND AND OBJECTIVE: Livedo reticularis racemosa and cerebrovascular lesions characterize Sneddon's syndrome. We report 23
patients with livedo racemosa and describe the association with thrombotic events. Our objective was to determine whether livedo racemosa may
be an independent clinical marker for the development of thrombotic events in patients who test negative for anti-phospholipid antibodies.
METHODS: Twenty-three patients with widespread livedo racemosa were studied. None of the patients were positive for anti-phospholipid
antibodies. The clinical protocol included a register of thrombotic events, fetal death or miscarriages, hypertension, and valvular heart disease.
Cerebral MRI and echocardiography were systematically performed in all patients. RESULTS: Nineteen patients (82.60%) had thrombotic events.
Fifteen (65.21%) had arterial thrombosis and eleven (47.82%) presented venous occlusions. Seven patients (30.43%) had both arterial and venous
thrombosis. Fetal losses were recorded in seven cases (30.43%), with a total number of 33; five patients had 3 or more fetal losses. Eleven out of
23 patients (47.82%) had valvular heart disease. Arterial hypertension was detected in 16 (69.56%) patients. Four patients did not have thrombotic
events but had other clinical manifestations. After anti-coagulation therapy was withdrawn, a new thrombotic event was observed in 9 out of the
14 treated patients (64.28%). CONCLUSIONS: Livedo racemosa seems to be a good clinical marker for the detection of hypercoagulable states
even in the absence of anti-phospholipid antibodies or other known biologic markers of thrombosis. Long-term anti-coagulation is probably
warranted in patients with livedo racemosa and a previous thrombotic event.

Two new isomeric acylated oleanane-type triterpenoids along with three known compounds were isolated from the MeOH extract of the dried fruits of Barringtonia racemosa. On the basis of spectroscopic methods, with special emphasis on 1D and 2D NMR techniques as well as chemical
methods, the structures were characterized as racemosol A (1) [22alpha-acetoxy-3beta,15alpha,16alpha,21beta-tetrahydroxy-28-(2-methylbutyryl) olean-12-ene] and isoracemosol A (2) [21beta-acetoxy-3beta,15alpha,16alpha,28-tetrahydroxy-22alpha-(2-methylbutyryl)olean-12-ene]. The isolated compounds (1-5) were not active against HeLa and P388 D1 carcinoma cell lines.

The special extract of CIMICIFUGA RACEMOSA (CR) BNO 1055 was shown to have bone protective effects without exerting estrogenic
effects in the uterus or mammary gland. Whether the effects of CR BNO 1055 would be exerted in other organs that also express estrogen
receptors (ERs) but in which the effects of estrogens and of the selective estrogen receptor modulator raloxifen (Ral) were not thoroughly studied
was therefore investigated in the present contribution. Rats were ovariectomized (ovx) and their food immediately substituted with estradiol benzoate (EB), Ral or 2 doses of CR BNO 1055 for 3 months. Expressions of estrogen receptor alpha (ERalpha), estrogen receptor beta (ERbeta) and of insulin-like growth factor-1 (IGF-1) genes were determined in the vagina, liver, thyroid gland, lung, spleen, colon and kidney by means of quantitative RT-PCRs. Body weights in all treatment groups were significantly reduced and uterine weights in the EB treated animals were largely and in the Ral treated animals slightly but significantly increased. CR BNO 1055 was without effects in the uterus. We tested 3 genes: ERalpha geneexpression was significantly reduced in the vagina, liver and kidney and remained unaffected in all other organs with the exception of the thyroid gland where ERalpha gene expression was stimulated by EB, Ral had - if any - similar effects in these organs. The CR extract BNO 1055 was devoid of any effect on ERalpha gene expression. ERbeta gene expression was suppressed in the vagina and colon by EB and this effect was sharedby Ral in the colon. In the thyroid, EB and Ral stimulated ERbeta gene expression. Expression of IGF-1 gene was stimulated by EB and CR BNO 1055 in the vagina and kidney and inhibited by EB and Ral in the liver. No effects were observed by CR BNO 1055 in these organs. The effects of Ral, if occurring, were similar to those of EB while CR BNO 1055 was ineffective in all organs but the vagina. In the colon, reduced ERbeta gene activity may augment ERalpha mediated effects. In all other organs the effects of ER await further investigation. The CR BNO 1055 did not show any activity pattern which would be similar to the pattern observed under EB or Ral. Therefore the observed effects of CR BNO 1055 in these organs are most likely not estrogenic in nature.

OBJECTIVE:: Black cohosh (BC), synonym for Actaea racemosa and Cimicifuga racemosa, is a herbal remedy for the treatment of menopausal
symptoms. Recently, worldwide discussions have emerged as to whether its use may be associated with the risk of rare hepatotoxicity in a few
susceptible women. METHODS:: We have evaluated the causal relationship in nine cases with suspected hepatotoxicity by the use of BC. The
updated Council for International Organizations of Medical Sciences scale was used to quantitatively assess the causality for BC.
RESULTS:: In eight of nine patients with liver disease, causality for BC +/- comedication was excluded (n = 4) or unlikely (n = 4). The failure to
ascribe causality in these cases was mainly due to alternative diagnosis, missing temporal association and dechallenge, and presentation of low
quality data. In only one case, causality was possible for a BC preparation of an unknown brand taken for 2 months with an unknown daily dose
. Confounding factors in this case include symptomatic cholelithiasis and fatty liver. Comedication with synthetic drugs and herbal or other dietary
supplements was reported in five of nine patients. CONCLUSIONS:: In nine cases of patients with liver disease, causality for BC +/- comedication
was possible (n = 1), unlikely (n = 4), or excluded (n = 4). Due to this lack of significant circumstantial evidence, the present study shows little, if any,hepatotoxic risks by the use of BC in the analyzed cases.

The effects of Ficus racemosa Linn. fruit extract and fraction on fasting serum glucose levels of normal, type 1 and type 2 diabetic model rats are
presented. The aqueous 80% EtOH extract and its water soluble fraction of F. racemosa fruit did not show any serum glucose lowering effect on
non-diabetic and type 2 diabetic rats at the fasting condition, whereas the extract showed significant hypoglycaemic effect on the type 1 diabetic
model rats. Both the extract and fraction were consistently active in both non-diabetic and types 1 and 2 diabetic model rats when fed
simultaneously with glucose load. On the contrary, they were ineffective in lowering blood glucose levels when fed 30 min prior to glucose load.
The 1-BuOH soluble part of the ethanol extract exhibited significant antioxidant activity in DPPH free radical scavenging assay. 3-O-(E)-Caffeoyl
quinate (1) was isolated for the first time from this plant, which also showed significant antioxidant activity.

OBJECTIVES: We examined the prevalence of LAC, aCL antibodies (Abs), anti-beta(2)-glycoprotein I (anti-beta(2)GPI) Abs and anti-
phosphatidylserine-prothrombin complex (anti-PS/PT) Abs in patients with regular livedo reticularis or with livedo racemosa to determine whether
those Abs correlate with the clinical or serological features. Assuming that a correlation exists, early recognition of the serological features of the
cutaneous manifestations may aid in the treatment and prediction of complications. METHODS: We examined the prevalence of LAC, aCL Abs,
anti-beta(2)GPI Abs and anti-PS/PT Abs in 143 Japanese patients who presented at our department with regular livedo reticularis or livedo
racemosa between 2003 and 2008. LAC was determined according to the guidelines recommended by the Subcommittee on Lupus
Anticoagulant/Phospholipid-Dependent Antibodies. Levels of anti-PS/PT, aCL and anti-beta(2)GPI Abs in serum samples taken from patients weremeasured by specific ELISAs. RESULTS: Anti-PS/PT Abs were detected in 94 (65.7%) of the livedo patients. Further, IgM anti-PS/PT Abs were detected in 90 (62.9%) of the livedo patients. Serum IgM anti-PS/PT Ab levels were significantly higher in livedo racemosa patients compared with regular livedo reticularis (19.2 +/- 17.0 vs 8.93 +/- 8.48 U/ml, P = 0.0013). Cutaneous vasculitis was significantly more prevalent among patients with livedo racemosa compared with regular livedo reticularis (P = 0.0014). Livedo racemosa patients had significantly higher CRP serum levels than regular livedo reticularis patients. Livedo racemosa has a stronger association with skin ulceration and arthralgia compared with regular livedoreticularis. Overall, we found a statistically significant association between cutaneous vasculitis and ischaemic cerebrovascular events in our livedo patients. CONCLUSIONS: We speculate that IgM anti-PS/PT Abs could be implicated in disease susceptibility for livedo racemosa. We further suspect that cutaneous vasculitis could be closely related to pathogenic factors that trigger the development of livedo racemosa. Early detection of cutaneous vasculitis in skin biopsies of livedo patients should be useful for prognostic evaluation, including ischaemic cerebrovascular events.

As an extension of work on the recently discovered nitrogenous metabolites from Cimicifuga/Actaea species, three new guanidine alkaloids have
been isolated and characterized from C. racemosa (syn. A. racemosa) roots. Of these, cyclo-cimipronidine (1) and cimipronidine methyl ester (2)
are congeners of cimipronidine (3), whereas dopargine (5) is a derivative of dopamine. By employing NMR- and MS-guided chemodiversity
profiling of a polar serotonergic (5-HT(7)) fraction, the guanidine alkaloids were initially detected in a clinical extract of black cohosh and were
isolated along with a congener of salsolinol 4, 5, and 3-hydroxytyrosol 3-O-glucoside (7). The structures of 1, 2, and 5 were confirmed by 1D and
2D NMR spectroscopy as well as LC-MS and HRMS spectroscopy. A plausible biosynthetic relationship may be inferred between the
homoproline-analogue cimipronidines and the dopamine-derived Cimicifuga alkaloids. These strongly basic and frequently zwitterionic nitrogenous
metabolites contribute considerable chemical diversity to the polar serotonergic fraction of black cohosh.

We investigated the potential of symplocomoside (1) and symponoside (2), glycosides isolated from the bark of Symplocos racemosa to inhibit
thymidine phosphorylase (TP) activity and associated angiogenesis. Compound 1 was a reversible, noncompetitive inhibitor of deoxythymidine
binding to TP (IC(50) = 65.45 +/- 5.08 microM; K(i) = 62.83 +/- 2.10 microM) and 2 was a reversible, uncompetitive inhibitor (IC(50) = 94.17
+/- 4.05 microM; K(i) = 101.95 +/- 1.65 microM). Molecular modeling analysis indicated that both compounds bound at the active site of the
enzyme but not solely to amino acid residues involved in catalysis. Both compounds were active in in vitro angiogenic assays inhibiting endothelial
cell migration and invasion in Matrigel, but did not inhibit growth factor-induced proliferation and were not cytotoxic. Compound 1 may have
potential as an anti-angiogenic and anti-tumor agent.

Black cohosh (Cimicifuga racemosa) is used to treat discomfort during menopause and as a substitute for synthetic drugs in hormone replacement
therapy. The mostly wildcrafted plant is ranked among the top-selling herbs in the United States. There is a risk for adulteration with the
similar-looking C. americana, which grows in the same habitats of the eastern United States. Other adulterants found in today's global marketplace
are the 3 Asian Cimicifuga species C. foetida, C. heracleifolia, and C. dahurica. A very practical, rapid, and reliable high-performance thin-layer
chromatographic (HPTLC) method was developed for identification of C. racemosa and detection of its most common adulterants by fingerprint
profiles. With specific derivatization reagents, mixtures of C. racemosa with a minimum of 5% of one of the adulterants can be detected. The propose
d method was validated with respect to specificity, stability, precision, and robustness. It can be used for quality control of black cohosh raw
material in a current Good Manufacturing Practices environment.

OBJECTIVE: The effect of Cimicifuga racemosa (CR) treatment was evaluated in healthy symptomatic post-menopausal women using the
Cervantes health-related quality of life (HR-QoL) scale. DESIGN: A prospective observational study was carried out in 122 healthy symptomatic
post-menopausal Spanish women with elevated body weight, aged between 45 and 59 years. Three groups were formed according to age intervals.
Each patient completed the Cervantes HR-QoL scale before and after CR treatment (20 mg, twice a day for 3 months). Changes in Cervantes
scale global quality of life scores as well as in their domains (menopause and health, psychic, sexuality and couple relationship) were analysed.
RESULTS: The CR treatment ameliorated global quality of life in both the whole group of patients and when women were analysed by age
subgroups. There were significant positive changes in Z scores for the Cervantes HR-QoL scale 'menopause and health', and 'psychic' domains in
both the entire population and by age groups. The 'sexuality domain' significantly improved when the entire population was assessed, but not when
each age-group was separately analysed; while there were no changes in 'couple relationship domain' scores. CONCLUSION: CR treatment
increased both global quality of life and the four domains of the Cervantes HR-QoL scale, being an effective treatment to reduce symptoms in
post-menopausal woman with elevated body weight.

15:Phytochemistry of cimicifugic acids and associated bases in Cimicifuga racemosa root extracts.

of Pharmacy, University of Illinois at Chicago, Chicago, IL 60612, USA.
INTRODUCTION: Earlier studies reported serotonergic activity for cimicifugic acids (CA) isolated from Cimicifuga racemosa. The discovery of
strongly basic alkaloids, cimipronidines, from the active extract partition and evaluation of previously employed work-up procedures has led to the
hypothesis of strong acid/base association in the extract. OBJECTIVE: Re-isolation of the CAs was desired to permit further detailed studies. Based on the acid/base association hypothesis, a new separation scheme of the active partition was required, which separates acids from associated bases.
METHODOLOGY: A new 5-HT(7) bioassay guided work-up procedure was developed that concentrates activity into one partition. The latter
was subjected to a new two-step centrifugal partitioning chromatography (CPC) method, which applies pH zone refinement gradient (pHZR CPC)
to dissociate the acid/base complexes. The resulting CA fraction was subjected to a second CPC step. Fractions and compounds were monitored
by (1)H NMR using a structure-based spin-pattern analysis facilitating dereplication of the known acids. Bioassay results were obtained for the
pHZR CPC fractions and for purified CAs. RESULTS: A new CA was characterised. While none of the pure CAs was active, the serotonergic
activity was concentrated in a single pHZR CPC fraction, which was subsequently shown to contain low levels of the potent 5-HT(7) ligand,
N(omega)-methylserotonin. CONCLUSION: This study shows that CAs are not responsible for serotonergic activity in black cohosh. New
phytochemical methodology (pHZR CPC) and a sensitive dereplication method (LC-MS) led to the identification of N(omega)-methylserotonin as
serotonergic active principle. Copyright (c) 2009 John Wiley & Sons, Ltd.

Alternative medicine preparations represent a significant industry worldwide. Black cohosh (Cimicifuga racemosa), a buttercup plant grown in
North America, is one such popular preparation for the treatment of menopausal symptoms. Because the proportion of women experiencing
climacteric symptoms is high, black cohosh merits further study as to its efficacy and safety. Convincing evidence for its efficacy in this setting
remains to be demonstrated. The purpose of this systematic review was to assess the current literature on the benefits of black cohosh for women
experiencing climacteric symptoms. To this end, a PubMed search was conducted on 1 November 2007 using the search terms 'black cohosh'
AND 'menopause'. The search was limited to randomized controlled trials in the English language involving adults. Several additional reviews
dealing with alternative therapies for menopause were included to capture additional older and non-English language literature. Ultimately, 16
studies eligible for review were identified. Many of the studies had conflicting results. Methodological flaws included lack of uniformity of the
drug preparation used, variable outcome measures and lack of a placebo group. The benefits of black cohosh in the management of climacteric
symptoms remain to be proven. Case studies suggest an additional unexplored area of adverse events that also needs to be addressed.
