Sirotkin AV. Positive effects of rutin on female reproduction. Reprod Domest Anim 2024; 59:e14540. [PMID: 38404048 DOI: 10.1111/rda.14540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 12/30/2023] [Accepted: 01/21/2024] [Indexed: 02/27/2024]
Abstract
This article reviews the source and properties of rutin (vitamin P), its general physiological and medicinal effects and their mechanisms, but the main subject of it is the currently available knowledge concerning the character and mechanisms of action of rutin on female reproductive processes. The available data demonstrate the stimulatory action of rutin on female reproductive processes: it can promote ovarian follicles development and ovulation, ovarian cyclicity, and viability of ovarian cells. On the other hand, it can suppress ovarian cancer cell and tumour development by inhibition of cell proliferation and growth and activation of their apoptosis and death. Furthermore, it could be able to prevent other reproductive disorders (ischaemia, polycystic ovarian syndrome, toxic effects of chemotherapy, nanoparticles and toluene). Rutin could exert its effects via changes in the release and reception of gonadotropin, ovarian steroid hormones, prostaglandins, cytokines, VEGF, as well as in intracellular regulators and markers of oxidative and inflammatory processes, proliferation, apoptosis and angiogenesis.

Phytoestrogens and Health Effects. Nutrients 2023; 15:nu15020317. [PMID: 36678189 PMCID: PMC9864699 DOI: 10.3390/nu15020317] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 12/31/2022] [Accepted: 01/03/2023] [Indexed: 01/10/2023] Open
Abstract
Phytoestrogens are literally estrogenic substances of plant origin. Although these substances are useful for plants in many aspects, their estrogenic properties are essentially relevant to their predators. As such, phytoestrogens can be considered to be substances potentially dedicated to plant-predator interaction. Therefore, it is not surprising to note that the word phytoestrogen comes from the early discovery of estrogenic effects in grazing animals and humans. Here, several compounds whose activities have been discovered at nutritional concentrations in animals and humans are examined. The substances analyzed belong to several chemical families, i.e., the flavanones, the coumestans, the resorcylic acid lactones, the isoflavones, and the enterolignans. Following their definition and the evocation of their role in plants, their metabolic transformations and bioavailabilities are discussed. A point is then made regarding their health effects, which can either be beneficial or adverse depending on the subject studied, the sex, the age, and the physiological status. Toxicological information is given based on official data. The effects are first presented in humans. Animal models are evoked when no data are available in humans. The effects are presented with a constant reference to doses and plausible exposure.

Use of Medicinal Plants during Pregnancy, Childbirth and Postpartum in Southern Morocco. Healthcare (Basel) 2022; 10:healthcare10112327. [DOI: 10.3390/healthcare10112327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 11/08/2022] [Accepted: 11/13/2022] [Indexed: 11/22/2022] Open
Abstract
Southern Morocco, particularly the Guelmim-Oued Noun region, is rich in a wide diversity of plant species. Pregnant women in this region use medicinal plants during pregnancy and childbirth for various purposes; however, the use of these plants has never been documented. The objectives of this study are threefold: to estimate the prevalence of medicinal plant uses by pregnant women in the province of Guelmim, Morocco, to describe the traditional practices of self-medication and to determine the associated factors. This is a multicenter cross-sectional study with descriptive and analytical approaches. Data were collected using an interview questionnaire, which was administered to pregnant women at health care centers and hospitals in the province of Guelmim. A total of 560 women participated in this study. The prevalence of medicinal plant use was 66.96%. Artemisia herba-alba Asso, Thymus maroccanus Ball., Trigonella foenum-graecum L., Aloysia citriodora Palau, Lepidium sativum L. and Cuminum cyminum L. were the plants with the highest UV. Pain, the induction and facilitation of childbirth, flu syndrome and anemia were the most listed reasons for use. The use of medicinal plants was significantly associated with the level of education (chi-square = 15.651; p = 0.004), and pregnancy monitoring (chi-square = 5.283; p = 0.028). In the province of Guelmim, the prevalence of the use of medicinal plants by women during pregnancy and childbirth is high. Further research is necessary in order to explore potential associated risks and complications.

Searching for Silphium: An Updated Review. HERITAGE 2022. [DOI: 10.3390/heritage5020051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
From luxury spice to medical cure-all, silphium was a product coveted throughout the ancient world and occupied an essential place in the export economy of ancient Cyrene. The mysterious extinction of the silphium plant in the 1st century CE leaves us with little evidence as to the exact nature of this important agricultural product. In this paper, an historical background on the kingdom of Cyrene is provided, evidence for the nature of the silphium plant is reviewed, how and why it was consumed and traded is discussed. Possible causes of extinction are considered in the context of plant genetics, biometrics, and soil geochemistry. Next, we demonstrate how modern medical studies conducted on possible living relatives can inform us about claims made by ancient authors as to the medical uses of the silphium plant, including its use as a contraceptive and abortifacient. Finally, methods for recovering silphium are explored. We show how underwater archaeology and the search for ancient shipwrecks off the northern coast of Libya may offer our best chance for the recovery of botanical remains of ancient silphium, and how ancient DNA may be able to establish the genetic makeup of this elusive plant.

Abstract
Even though several plants can improve the female reproductive function, the use of herbs, herbal preparations, or essential oils during pregnancy is questionable. This review is focused on the effects of some essential oils and their constituents on the female reproductive system during pregnancy and on the development of the fetus. The major concerns include causing abortion, reproductive hormone modulation, maternal toxicity, teratogenicity, and embryo-fetotoxicity. This work summarizes the important studies on the reproductive effects of essential oil constituents anethole, apiole, citral, camphor, thymoquinone, trans-sabinyl acetate, methyl salicylate, thujone, pulegone, β-elemene, β-eudesmol, and costus lactone, among others.

Antioxidants (Basel) 2020; 9:antiox9020143. [PMID: 32041310 PMCID: PMC7070924 DOI: 10.3390/antiox9020143] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 02/02/2020] [Accepted: 02/02/2020] [Indexed: 12/22/2022] Open
Abstract
Hagenia abyssinica (Bruce) J. F. Gmel. is a multipurpose dioecious tree that has been used to treat various ailments, for example, the flowers of H. abyssinica have been widely used as a tea to treat intestinal parasites by local residents and the roots of H.abyssinica could also be used for anticancer purposes. Antioxidant activity could be one of the most important pathways to suppress cancer and there is hardly any information available on the specific chemical components corresponding to the bioactivities of H. abyssinica to date. The present study intended to screen and evaluate the antioxidant and anti-proliferative properties of five different fractions from H. abyssinica along with their corresponding total flavonoid and phenolic contents and then further identify those compounds with the most potent antioxidant and anti-proliferative activities using high performance liquid chromatography (HPLC) coupled to mass spectrometry (MS) and nuclear magnetic resonance (NMR). The total flavonoid and phenolic content assays showed that the ethyl acetate (EA) fraction of H. abyssinica had higher flavonoid and phenolic levels than the other four fractions. Furthermore, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) superoxide radical scavenging abilities, total antioxidant capacity (TAC) assay with 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS), and ferric-reducing antioxidant power (FRAP) were measured to evaluate the antioxidant activities of the five fractions and some pure compounds isolated from the EA fraction, which displayed higher antioxidant properties than that of the other fractions. Caffeic acid from the EA fraction showed even stronger DPPH scavenging ability (IC50 7.858 ± 0.31 µg/mL) than that of Vc (IC50 8.27 ± 0.11 µg/mL) as the positive control. The anti-proliferative properties of four fractions and the ethanol extract were evaluated by the 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and the EA fraction exhibited higher anti-proliferative activities against three cancer cell lines than that of the other fractions. Additionally, the compounds with good antioxidant activity from the EA fraction of H. abyssinica were screened and identified using LC-MS and NMR and were also found to possess good anti-proliferative activity. In the MTT assay, the quercetin showed the strongest dose-dependent anti-proliferative activities to colon cancer cells (HT-29) and liver cancer cells (HepG2) among all of the compounds isolated. This study provided valuable information on the synergistic antioxidant and anti-proliferative properties of H. abyssinica.

Abstract
Pig husbandry is an important farming component in Nagaland which plays a significant socio-economic role in the livelihood of Naga tribes. The present study documented the Indigenous Traditional Knowledge (ITK) on pig farming as practised by tribal farmers in Nagaland. Some commonly used plants for feed were Manihot esculenta, Colocasia esculenta L., Ipomea batata, Euphorbia hirta L., Musa spp., Eichhornia crassipe, Bidens spilosa Ficus hispida L. etc. Ethnoveterinary plants identified were Oroxylum indicum for treatment of oral and foot lesion in FMD and also for deworming; Rhus chinensis for treatment of fever; Hibiscus cannabinus L. for fever and dysentery; Spondias pinnata, Rhus similata and Curcuma caesia, guava, bamboo, banana, papaya against diarrhoea and dysentery; Gynura cusimbua for its healing properties and Cinnamomum verum as anti-helminthic. Gur for diarrhoea and dysentery; brick powder and wood ash for deworming; beehives for curing fever and termite's earth for prevention of piglet's anaemia were reported for the first time. Other plants which were documented in the present study were Carica papaya L., Lagenaria siceraria, Citrus spp. and Ananas comosus (L.) Merr. as abortifacient; application of wood ashes with kerosene oil after castration to prevent bleeding and as disinfectant and Carica papaya as galactogogue.

Abstract
PURPOSE OF REVIEW The estrogenic effects of genistein, as reconfirmed by the American National Toxicology Program (USA-NTP), have led to several new clinical studies being undertaken. Here, we highlight the most relevant recent data, reporting either beneficial or adverse effects. RECENT FINDINGS Phytoestrogens are natural molecules from edible plants exhibiting estrogenic activities. Post-USA-NTP studies investigated both human and animal reproductive and other physiological issues. These studies showed that estrogens can be either deleterious for reproduction and estrogen-dependent diseases, or beneficial for those with steroid deficiencies, that is more than 50. The specific outcome depends on exposure level and on the estrogenic status of the patients exposed. Recently, it was reported that, with the industrialization of soybean process, phytoestrogen exposure dramatically increased in both humans and cattle, whereas traditional Asian soy-food-processing empirically removed isoflavones. Phytoestrogen exposure has also become more widespread with the progressive internationalization of soybean use in human and cattle food. SUMMARY Phytoestrogens should be considered as modern endocrine disruptors and studied as such.

Abstract
Fenugreek (Trigonella foenum graecum), used as traditional medicine and natural additive food, has been shown to exert significant antiatherogenic, antidiabetic, antianorexic, antioxidant, anticarcinogenic, antihyperlipidemic, galactogogue and anti-inflammatory effects in several human and animal models. Besides, several medicinal pharmaceutical and nutraceutical properties, fenugreek have toxic effects as well. The aim of this review is discuss the cumulative evidence, which suggests that consumption of fenugreek induced some serious toxicological side effects. In this review, many teratogenic effects of fenugreek, from congenital malformations to death, were reported in human, rodent, rabbit, and chick. Moreover, results obtained in rats, mice and rabbits show a testicular toxicity and anti-fertility effects in male associated with oxidative stress and DNA damage, as well as anti-fertility, antiimplantation and abortifacient activity in females related to saponin compound of fenugreek which suggest that fenugreek is not recommended for use during pregnancy. Indeed, the consumption of fenugreek should be avoided for persons having peanut and chickpeas allergy because of possible cross-reactivity as well as chronic asthma. Accumulating evidence suggest also that fenugreek may have neurodevelopmental, neurobehavioral and neuropathological side effects. It is suggested that future studies would be conducted to identify molecular and cellular mechanisms underlying the fenugreek toxicological properties.

JOURNAL OF ETHNOPHARMACOLOGY 2016; 178:307-322.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Central America, most Maya women use ethnomedicines for all aspects of their reproductive cycle including menstruation, pregnancy and menopause. However, very few of these plants have been documented, collected and tested in appropriate pharmacological assays to determine possible safety and efficacy. The aim of this work was to provide an overview of information on the ethnomedical uses, ethnopharmacology, chemistry and pharmacological research for medicinal plants used for women's reproductive health in Guatemala, with a special emphasis on the Q'eqchi Maya of the Lake Izabal region, to demonstrate therapeutic potential and support future research in the field. MATERIALS AND METHODS Reviews of the ethnobotanical, ethnomedical and ethnopharmacological literature were performed for 30 plants collected in the Lake Izabal region of Guatemala and used by the Q'eqchi Maya for treatment of reproductive health issues were performed up to and including July 2015 using multiple databases, library searches for abstracts, books, dissertations, and websites. RESULTS AND CONCLUSIONS Review of the published research confirms that many of the plants used by Q'eqchi Maya women for the management of reproductive health issues have pharmacological activities, including analgesic, anti-inflammatory, estrogenic, progestagenic and/or serotonergic effects, that support the use of these plants and provide plausible mechanisms of action for their traditional uses. Furthermore, a new serotonin agonist, 9, 10-methylenedioxy-5, 6-Z-fadyenolide was isolated, thereby demonstrating an untapped potential for drug discovery. However, to date much of the pharmacological assays have been in vitro only, and few in vivo studies have been performed. Considering the large percentage of the Maya population in Guatemala that use traditional medicines, there remains a significant lack of pharmacological and toxicological data for these plants. Future research should focus on the safety and efficacy of medicinal plants using in vivo preclinical studies and clinical trials, as well as chemical analysis. Since medicinal plants from the Piperaceae are most commonly used as traditional medicines by the Q'eqchi Maya women, and new bioactive compounds have been identified from Piper species, investigations of commonly used plants from this family would be an appropriate place to start. Data generated from such studies would contribute to Guatemala's national effort to promote a complementary relationship between traditional Maya medicine and public health services.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plant based traditional medicines for birth control has been in practice in rural populations of North-East India, since time immemorial. Fresh rhizome of Drynaria quercifolia (L.) J. Smith is one of the plant parts used traditionally by different ethnic communities in Tripura, India for birth control. The present investigation is aimed to justify the scientific basis in traditional use of Drynaria quercifolia rhizome as anti-fertility agent. MATERIALS AND METHODS Ex-vivo uterotonic activity was done on uterine tissue. Acute toxicity test of the plant extract was carried out in rats of both sexes. The abortifacient and anti-implantation activities of the extract were investigated, in-vivo and estimated the level of different hormones release. RESULTS The result revealed the effectiveness of methanol (87%) and aqueous (68%) extract of the plant on uterotonic activity. The extracts showed relatively non-toxic effect in acute toxicity study. Methanolic extract has shown higher efficacy for both abortifacient (**p<0.01) and anti-implantation performance (**p<0.01) and also effected hormone release level (**p<0.01). CONCLUSION Methanolic extract of Drynaria quercifolia (L.) J. Smith rhizome has been proved to have significant anti-fertility activity.

Abstract
Isoflavones are phytoestrogens with potent estrogenic activity; genistein, daidzein and glycitein are the most active isoflavones found in soy beans. Phytoestrogens have similarity in structure with the human female hormone 17-β-estradiol, which can bind to both alpha and beta estrogen receptors, and mimic the action of estrogens on target organs, thereby exerting many health benefits when used in some hormone-dependent diseases. Numerous clinical studies claim benefits of genistein and daidzein in chemoprevention of breast and prostate cancer, cardiovascular disease and osteoporosis as well as in relieving postmenopausal symptoms. The ability of isoflavones to prevent cancer and other chronic diseases largely depends on pharmacokinetic properties of these compounds, in particular absorption and distribution to the target tissue. The chemical form in which isoflavones occur is important because it influences their bioavailability and, therefore, their biological activity. Glucose-conjugated isoflavones are highly polar, water-soluble compounds. They are hardly absorbed by the intestinal epithelium and have weaker biological activities than the corresponding aglycone. Different microbial families of colon can transform glycosylated isoflavones into aglycones. Clinical studies show important differences between the aglycone and conjugated forms of genistein and daidzein. The evaluation of isoflavone metabolism and bioavailability is crucial to understanding their biological effects. Lipid-based formulations such as drug incorporation into oils, emulsions and self-microemulsifying formulations have been introduced to increase bioavailability. Complexation with cyclodextrin also represent a valid method to improve the physicochemical characteristics of these substances in order to be absorbed and distributed to target tissues. We review and discuss pharmacokinetic issues that critically influence the biological activity of isoflavones.

[PMID: 22753347 DOI: 10.1002/ps.3354] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2011] [Revised: 03/28/2012] [Accepted: 04/26/2012] [Indexed: 06/01/2023]
Abstract
BACKGROUND Plant extracts can inhibit fertility by adversely affecting, directly or indirectly, reproductive processes ranging from gonadal function and development to gestation. This review focuses on plant extracts that disrupt ovarian function in rodents. RESULTS Extracts from at least 40 plant species exert some of their disruptive reproductive effects at the ovarian level. Of those, 13 plants induce a reduction in the number and type of ovarian follicles and also cause disruption to the oestrous cycle. Their effects are short term and reversible once treatment ceases. CONCLUSIONS Protection of plant extracts to prevent their degradation before uptake in the gastrointestinal tract could enhance short-term efficacy but would not enhance the longevity of their effects. Identification and further testing of the specific chemicals responsible for reproductive effects would be beneficial. The adoption of a standard protocol for treatment and assessment of the inhibitory effects of potential control agents on reproductive function in rodents is essential. Treatment with higher concentrations of extracts in conjunction with other extracts or with other chemosterilants could have potential complementary effects and lead to more rapid and permanent changes in ovarian function. An orally delivered agent(s) that causes major depletion of all follicle types, and particularly of non-regenerating primordial follicles, could be an ideal fertility control product and serve as an additional tool for population control of pest rodents.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional remedies from plants have been use to treat male reproductive related disorders for ages in South Africa. AIM This study reviewed the current status of medicinal plants used in male reproductive healthcare as well as their effectiveness as a mode of treatment. METHODOLOGY A detailed literature search was done by consulting books, peer-reviewed papers, scientific databases such as Scopus, Science direct and PubMed, and Google scholars. Keywords such as aphrodisiacs, conception, erectile dysfunction, fertility, infertility and sterility in relation to medicinal plants were used during the search. Plant species were selected based on their traditional use in different aspects of male reproductive healthcare. RESULTS A total of 61 plants species were found to be used in treating male impotency or as aphrodisiacs. However, only six species have been evaluated scientifically and these plants showed significant activities either in promoting conception by improving fertility and promoting erection or in contraception by decreasing sperm motility, virility and membrane integrity. CONCLUSION The importance of herbal products in the treatment of male infertility and related sexual disorders is undeniable. Scientific evaluations of the six species have proved the empirical use of these plants in the improvement of male sexual disorders as well as validating their traditional uses.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional medicines are practiced worldwide for regulation fertility since ancient times. This review provides a comprehensive summary of medicinal flora inhabitating throughout the world regarding their traditional usage by various tribes/ethnic groups for fertility regulation in females. MATERIALS AND METHODS Bibliographic investigation was carried out by analyzing classical text books and peer reviewed papers, consulting worldwide accepted scientific databases from the last six decades. Plants/their parts/extracts traditionally used for abortion, contraception, emmenagogue and sterilization purposes have been considered as antifertility agents. Research status of selected potential plant species has been discussed. Further, compounds isolated from plants with attributed fertility regulating potentials are also classified into three categories: (a) phytoconstituents with anti-implantation activity, (b) phytoconstituents with abortifacient activity and (c) phytoconstituents with contraceptive activity. RESULTS 577 plant species belonging to 122 families, traditionally used in fertility regulation in females, have been recorded, of which 298 plants have been mentioned as abortifacients (42%), 188 as contraceptives (31%), 149 as emmenagogues (24%), and 17 as sterilizers. Among 122 plant families, fabaceae constitutes 49.2%, asteraceae 40.98%, euphorbiaceae 19.7%, apiaceae 16.4%, poaceae 12.3%, labiateae 11.5%, and others in lesser proportion. Various plant parts used in fertility regulation include leaves (25%), roots (22%), fruits (15%), seeds (12%), stem/stem bark (37%), and flowers (4%). Some active compounds, isolated from about various plant species, have been reported to possess significant antifertility potential. CONCLUSION This review clearly indicates that it is time to increase the number of experimental studies to find out novel potential chemical entities from such a vast array of unexploited plants having traditional role in fertility regulation. Also, the mechanisms of action by which plant extracts and their active compounds exert antifertility effects remain to be studied.

Abstract
CONTEXT Jacaranda decurrens subsp. symmetrifoliolata Farias & Proença (Bignoniaceae) is a species widely used for their medicinal properties. At least to our known, no study has been conducted concerning its toxicological profile after gestational and lactational exposure. OBJECTIVE The present study was carried out to evaluate the effects of J. decurrens on development of the reproductive system in male rats. MATERIALS AND METHODS Pregnant rats were treated daily (gavage) with 250 or 500 mg/kg/day of aqueous extract of J. decurrens or vehicle, from day 12 of pregnancy to day 21 of lactation. RESULTS AND DISCUSSION Both doses of J. decurrens significantly anticipated (p < 0.05) the age of testicular descent to the scrotum, a parameter indicative of puberty initiation. Furthermore, at puberty, there was a significant reduction (p < 0.05) in testicular and epididymis weights in the offspring exposed to the higher dose of extract, without effect on sperm production and the histology of reproductive organs. On the other hand, at adulthood, the reproductive parameters analyzed did not differ among groups. CONCLUSIONS J. decurrens, in this experimental model, interfered with the initial development of the reproductive system, but without lasting effects on sperm production in adulthood.

Abstract
BACKGROUND Spermicides represent one of the methods of contraception. The synthetic agents available as spermicides produce severe side effects. Hence, there is a need to replace these agents with safe and effective agents such as plant-based contraceptive agents. STUDY DESIGN The objective of the present study was to develop and evaluate a stable, safe, effective and easily acceptable contraceptive delivery system containing herbal drug. Efforts were made to evaluate the contraceptive potential of the hydroalcoholic extract from the seeds of Annona squamosa Linn. and the vaginal gel HerbOshield™ containing the extract. RESULTS Spermicidal effect was evaluated in vitro using healthy human spermatozoa and in vivo in rats. The in vitro results demonstrated that HerbOshield™ vaginal gel is an effective spermicide. At a 100-mg/mL dose, complete immobilization of human spermatozoa was observed within 20 s. None of the treated animals conceived, indicating 100% contraceptive effect as compared to Gynol II, a nonoxynol-9-containing marketed formulation, which showed only 67% contraceptive effect in vivo. HerbOshield™ vaginal gel was found to be safe in animals during a 14-day toxicity study. CONCLUSIONS HerbOshield™ vaginal gel was found to be safe and effective in rats and could be developed as a potential vaginal contraceptive for future use in humans.

Abstract
Yanesha, also called Amuesha, is a group of amerindian people, belonging to the arawak linguistic family. They dwell in the central region of Peru, at the oriental foothills of the Andes. Their territory covers a large range of ecological settings, and communities spread from 1800 down to 400 m/snm. The Yanesha culture is vivid to this day, and people strongly rely on traditional medicine in their everyday life. An exhaustive ethnopharmacological survey leads us to collect 249 species with medicinal uses. An overview of the Yanesha pharmacopoeia, linked with ethnomedicinal practices is presented in this paper.

Abstract
Phytoestrogens are secondary plant compounds, which can act to mimic estrogen and cause the disruption of estrogenic responses in organisms. Although there is a substantial body of research studying phytoestrogens, including their mechanisms of estrogenic effects, evolution, and detection in biological systems, little is known about their ecological significance. There is evidence, however, that an ecological relationship involving phytoestrogens exists between plants and animals-plants may produce phytoestrogens to reduce fecundity of organisms that eat them. Birds and other vertebrates may also exploit phytoestrogens to regulate their own reproduction-there are well known examples of phytoestrogens inhibiting reproduction in higher vertebrates, including birds. Also, common plant stressors (e.g., high temperature) increase the production of secondary plant compounds, and, as evidence suggests, also induce phytoestrogen biosynthesis. These observations are consistent with the single study ever done on phytoestrogens and reproduction in wild birds [Leopold, A.S., Erwin, M., Oh, J., Browning, B., 1976. Phytoestrogens adverse effects on reproduction in California quail. Science 191, 98-100.], which found that drought stress correlated with increased levels of phytoestrogens in plants, and that increased phytoestrogen levels correlated with decreased young. This review discusses the hypothesis that plants may have an effect on the reproduction of avian species by producing phytoestrogens as a plant defense against herbivory, and that birds may "use" changing levels of phytoestrogens in the vegetation to ensure that food resources will support potential young produced. Evidence from our laboratory and others appear to support this hypothesis.

Abstract
This study was designed to assess the effect of the phytoestrogenic compound ferutinin, chronically administered in ovariectomized progesterone primed rats, alone or in combination with estradiol benzoate. After 2, 3 and 4 weeks of treatments, female rats were tested for receptive (lordosis) and proceptive behaviors (hops, darts and ear wigglings). Ferutinin given alone markedly increased the intensity of the lordotic response in ovariectomized rats but failed to significantly affect proceptivity. On the other hand estradiol benzoate significantly increased both receptive and proceptive behaviors. When administered in combination with estradiol, ferutinin reduced the increase in receptivity and proceptivity due to estrogen effects, acting as an antiestrogen. At the end of the behavioral experiments, animals were sacrificed and Western blot analysis of estrogen receptor alpha (ERalpha) levels was performed in the dissected hypothalami. Ferutinin increased ERalpha expression when administered alone, as estradiol did, but decreased the response to estradiol when administered in combination. These results suggest that ferutinin displays estrogenic or antiestrogenic activity through ERalpha in the hypothalamus, depending on the absence or the presence of estrogen priming.

Abstract
This study investigated the role of oral phytoestrogens in improving pregnancy rate and cycle outcomes with clomiphene citrate. Patients with unexplained infertility and recurrent clomiphene citrate induction failure, were randomly divided into two groups: group I (n = 60) and group II (n = 59). Both groups received clomiphene citrate 150 mg per day (days 3 to 7). Group I received additional oral phytoestrogen (Cimicifuga racemosa) 120 mg/day from days 1 to 12. Human chorionic gonadotrophin (HCG) injection (10,000 IU i.m.) was given and timed intercourse was recommended when a leading follicle reached >17 mm and serum oestradiol exceeded 200 (pg/ml). There was a non-significant shortening of induction cycles in group I. Oestradiol and LH concentrations were higher in group I compared with group II. Endometrial thickness, serum progesterone and clinical pregnancy rate were significantly higher in group I (8.9 +/- 1.4 mm versus 7.5 +/- 1.3 mm, P < 0.001; 13.3 +/- 3.1 ng/ml versus 9.3 +/- 2.0 ng/ml, P < 0.01; 36.7% versus 13.6%, P < 0.01, respectively). It is concluded that adding C. racemosa rhizome dry extract to clomiphene citrate induction can improve the pregnancy rate and cycle outcomes in these couples.

Abstract
The pharmacokinetics and metabolism of lithospermic acid (LA), a component isolated from Salvia miltiorrhiza, and its two O-methylated metabolites (3'-monomethyl- and 3',3''-dimethyl-lithospermic acid), were analyzed by a rapid and specific isocratic liquid chromatography-tandem mass spectrometry (LC/MS/MS) method. Rat serum samples collected after intravenous and oral administration were analyzed for obtaining pharmacokinetic data of LA. Two O-methylated metabolites, namely one 3'-monomethyl- and one 3',3''-dimethyl-lithospermic acid were detected in rat serum and bile samples after intravenous and oral administration of LA, respectively. An oral bioavailability of 1.15% was found, with the AUC(0-t) values of 301.89 and 3.46mgh/L for intravenous and oral administration, respectively. The total recovery from bile was 75.36% (0.46% for LA, 17.23% for M1, and 57.67% for M2) after intravenous administration, and 4.26% (0.00% for LA, 0.10% for M1, and 4.16% for M2) after oral administration. These results indicate that methylation is the main metabolic pathway of LA, and that LA is excreted into rat bile and finally into feces.

Abstract
The effects of Azadirachta indica leaves (500 mg/kg body weight, orally/day), testosterone (0.25 mg/kg body weight/day, intramuscularly) and a combination of these two were investigated as to whether Azadirachta indica leaves affect the morphology of Leydig cells and epididymal sperm and their organelles at the ultrastructural level. Azadirachta indica treated rats showed atrophic seminiferous tubules with widening intercellular spaces. Leydig cells exhibited characteristics of degeneration such as indented nuclei; the commencement of degeneration was evident from less chromatin; the reduced amount of a marked decrease in organelle content and scarcity of other cell types of the interstitium in highly vacuolated cytoplasm, which were seem from both light and electron microscopic observations. The number of Leydig cells and their nuclear diameter were reduced significantly. Pathological changes in the spermatozoa of the cauda epididymis were observed and the spermatozoa retained cytoplasmic droplets. It is suggested that regression of Leydig cells and the absence of interstitium cell types indicates an androgen deficiency, which affects the spermatozoa in the epididymis by disturbing the internal epididymal milieu. The antiandrogenic and antispermatogenic properties of Azadirachta indica leaves appear to lead to a reduced fertilizing ability of the sperm.

Abstract
BACKGROUND The medicinal benefits of Echinacea sp. plants in several disease conditions, including insect bites, respiratory ailments, and even cancer and AIDS, have been touted for decades. Echinacea sp.-based phytoceuticals are among the top selling herbals in the Western marketplace today. However, evidence is very scant concerning the effects of using Echinacea species herbals during pregnancy. While available data indicates that fetal malformations do not occur during pregnancy in humans consuming this herb, there are no formal studies aimed at assessing the possibility that consuming Echinacea herbals may promote spontaneous abortions, thereby reducing the number of live births upon which to assess the presence or absence of malformations. OBJECTIVES We undertook a study in which pregnant mice were fed daily Echinacea purpurea from pregnancy onset until gestational days 10, 11, 12, 13, and 14. METHODS Maternal spleen and bone marrow were taken for enumeration of cells in each of five separate hemopoietic lineages/organ, and fetal status was recorded. RESULTS The data indicate that the significant, pregnancy-induced elevation in splenic lymphocytes and nucleated erythroid cells was all but eliminated in those females which consumed E. purpurea daily throughout their pregnancy. Moreover, consuming E. purpurea during pregnancy reduced the number of viable fetuses. CONCLUSIONS The data may be extrapolated to suggest that in humans, abstention from consuming Echinacea products during the early/mid stages of pregnancy, may be prudent.

Abstract
Previous works have demonstrated that stem bark extracts of Cola nitida (Sterculiaceae), Afrormosia laxiflora and Pterocarpus erinaceus (Fabaceae) provoked a blockade of female rat ovulation and estrous cycle by inhibiting pituitary LH release in vivo. In addition, these plant extracts exerted an inhibitory effect on LH release of rat pituitary cells. Therefore, these data could explain inhibitory effects of plant extracts on LH release in vivo. The present study was undertaken to examine the mechanisms by which these plants exert their antigonadotropic activities. So, we studied the biological activities of these plant extracts on pituitary cells in culture. Data show that C. nitida, A. laxiflora and P. erinaceus extracts only inhibit LH release and have no effect on FSH release. In fact, A. laxiflora, P. erinaceus and C. nitida extracts diminish LH release in culture medium without acting on rat pituitary cell content. Plant extracts form complexes with basic glycoproteins (but not with acid glycoproteins) and prevent them from entering the cells.

Abstract
The use of in vitro trout hepatocyte cultures is shown to provide a simple and effective way to screen plant and food products for oestrogenic activity. The relative oestrogenic activities of 0.1 g each of extracts of phytosterol, soy isoflavone, red clover, kudzu and soybean extracts were determined using this assay and found to be equivalent to 212, 1, 3.2, 132 and 1025 nM of 17beta-estradiol, respectively. Controls were performed on soybean and kudzu extracts using specific ELISAs for isoflavones and these confirmed the validity of the cell culture assay. The method described offers an advantage over current methods in that it can detect increased oestrogenic activity that may occur as a result of metabolic activation of pre- or pro-oestrogens liver cells.

Abstract
Interest in the use of plant estrogens (phytoestrogens) to attenuate postmenopausal bone loss has increased during the past 10 years as healthcare consumers, practitioners, and scientists have searched for alternative treatments to the use of hormone replacement therapy. Promising research has emerged regarding the potential benefit of increased consumption of phytoestrogens, primarily from dietary soy products. Dietary phytoestrogens, primarily isoflavones found in soy foods, may alter bone turnover in postmenopausal women by decreasing bone resorption and increasing bone formation.

Abstract
Phytoestrogens are a diverse group of plant-derived compounds that structurally or functionally mimic mammalian estrogens and show potential benefits for human health. The number of articles published on phytoestrogens has risen dramatically in the past couple decades. Further research continues to demonstrate the biological complexity of phytoestrogens, which belong to several different chemical classes and act through diverse mechanisms. This paper discusses the classification of phytoestrogens, methods of identification, their proposed mechanisms of action and botanical sources for phytoestrogens. The effects of phytoestrogens on breast and prostate cancers, cardiovascular disease, menopausal symptoms and osteoporosis will also be examined including research on benefits and risks.
