Abstract
BACKGROUND Around 10% of Americans meet the Rome IV criteria for functional dyspepsia (FD), with a significantly higher rate in women. FD also has a higher prevalence in women below the age of 50, suggesting that women who are affected are likely to be of reproductive age. Unfortunately, there is a lack of research or evidence-based guidelines on managing FD in pregnancy. AIMS AND METHODS To address this issue, we aimed to perform a systematic review of the interactions between FD and pregnancy and managing pre-existing FD in the peripartum and post-partum phases using current lifestyle, pharmacological, non-pharmacological and alternative medicine interventions. RESULTS Due to the lack of Rome IV FD-specific data in pregnancy, we instead performed a narrative review on how existing FD interventions could be extrapolated to the pregnant population. Where possible we use the highest level of available evidence or official guidelines to answer these questions, which often involves synthesising treatment and safety evidence of these interventions in other diseases during pregnancy. Finally, we highlight current substantial knowledge gaps requiring further research for the safe management of a pregnant patient with pre-existing FD. CONCLUSIONS Overall, despite the paucity of knowledge of treating FD during pregnancy, providers can mitigate this uncertainty by planning ahead with the patient. Patients should ideally minimise treatment until after breastfeeding. However, interdisciplinary resources are available to ensure that minimal-risk interventions are maximised, while interventions with more risks, if necessary, are justifiable by both the patient and the care team. Future investigations should continue to elicit the mechanistic relationship between FD and pregnancy while cautiously expanding prospective research on promising and safe therapies in pregnant patients with pre-existing FD.

Abstract
Diabetes mellitus (DM) and its complications have become an important global public health issue, affecting human health and negatively impacting life and lifespan. Pyroptosis is a recently discovered form of pro-inflammatory programmed cell death (PCD). To date, pyroptosis-associated inflammasome pathways have been identified primarily in the canonical and non-canonical inflammasome pathway, apoptotic caspase-mediated pathway, granzyme-mediated pathway, and streptococcal pyrogenic exotoxin B (SpeB)-mediated pathway. The activation of diabetes-mediated pyroptosis-associated factors play an important role in the pathophysiology of DM and its complications. Studies have shown that ginsenosides exert significant protective effects on DM and its complications. Through inhibiting the activation of pyroptosis-associated inflammasome pathways, and then the DM and its complications are improved. This review summarizes the subtypes of ginsenosides and their chemical characteristics, pharmacokinetics and side effects, the main pyroptosis-associated inflammasome pathways that have been discovered to date, and the potential mechanism of different subtypes of ginsenosides in the treatment of DM and its complications (such as diabetic cardiomyopathy, diabetic nephropathy, diabetic liver injury, diabetic retinopathy, and diabetic ischemic stroke) via anti-pyroptosis-associated inflammasome pathways. These findings may provide ideas for further research to explore ginsenoside mechanism in improving DM and its complications. However, many pyroptosis-associated inflammasome pathways and targets involved in the occurrence and development of DM and its complications are still unknown. In the future, further studies using in vitro cell models, in vivo animal models, and human disease models can be used to further elucidate the mechanism of ginsenosides in the treatment of DM and its complications.

Abstract
The decline in birth rates has become a very serious problem in various parts of the world. Many countries have implemented national programs for increasing birth rates, one of which involves the use of traditional medicine as an alternative solution. Among the fast-growing traditional medicines, traditional Chinese medicine (TCM) and traditional Indonesian medicine (TIM) have attracted a lot of demand globally. Here, we analyzed and compared the herbal medicines from TCM and TIM that must be avoided by pregnant women for preventing miscarriage and maintaining safety during pregnancy and the postpartum period. This review uses data from official reports from the respective government and national and international electronic databases for analysis. Although TCM and TIM have their own characteristics of treatment, they also have some similarities in concept and treatment, especially those related to herbal medicines. This review can be used as a reference base to help pregnant women consume herbal medicines at appropriate conditions and doses.

Abstract
About 80% of the consumers worldwide use herbal medicine (HMs) or other natural products. The percentage may vary significantly (7%-55%) among pregnant women, depending upon social status, ethnicity, and cultural traditions. This manuscript discusses the most common HMs used by pregnant women, and the potential interactions of HMs with conventional drugs in some medical conditions that occur during pregnancy (e.g., hypertension, asthma, epilepsy). It also includes an examination of the characteristics of pregnant HM consumers, the primary conditions for which HMs are taken, and a discussion related to the potential toxicity of HMs taken during pregnancy. Many cultures have used HMs in pregnancy to improve wellbeing of the mother and/or baby, or to help decrease nausea and vomiting, treat infection, ease gastrointestinal problems, prepare for labor, induce labor, or ease labor pains. One of the reasons why pregnant women use HMs is an assumption that HMs are safer than conventional medicine. However, for pregnant women with pre-existing conditions like epilepsy and asthma, supplementation of conventional treatment with HMs may further complicate their care. The use of HMs is frequently not reported to healthcare professionals. Providers are often not questioning HM use, despite little being known about the HM safety and HM-drug interactions during pregnancy. This lack of knowledge on potential toxicity and the ability to interact with conventional treatments may impact both mother and fetus. There is a need for education of women and their healthcare professionals to move away from the idea of HMs not being harmful. Healthcare professionals need to question women on whether they use any HMs or natural products during pregnancy, especially when conventional treatment is less efficient and/or adverse events have occurred as herbal-drug interactions could be the reason for these observations. Additionally, more preclinical and clinical studies are needed to evaluate HM efficacy and toxicity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anastatica hierochuntica (A. hierochuntica) is a plant consumed in folk medicine for the treatment of reproductive system related problems and metabolic disorders. It is of concern that the herb is commonly consumed by pregnant women towards the end of pregnancy to ease the process of labour, despite the lack of studies evaluating its safety. AIM OF THIS STUDY This study aimed to investigate the potential toxicity effects of A. hierochuntica in pregnant Sprague-Dawley rats and their developing foetuses. MATERIALS AND METHODS Experiments were conducted in accordance to the Organisation for Economic Co-operation and Development guideline 414. Animals were randomly divided into four groups (n = 10 females per group): negative control (received the vehicle only), experimental animals received 250, 500, and 1000 mg/kg A. hierochuntica aqueous extracts (AHAE), respectively. Treatment was administered daily by oral gavage from gestational day (GD) 6-20, and caesarian section performed on GD21. RESULTS There were significant reduction in the corrected maternal weight gain of dams and body weight of foetuses in the lowest and highest dose of AHAE-treated animals compared to the control. These findings were associated with the increase in anogenital distance index and multiple congenital anomalies observed in some of the offspring. On the other hand, rats treated with 500 mg/kg showed higher embryonic survival rate with absence of significant treatment-related effect. CONCLUSION Findings showed that highest and lowest doses of AHAE have prenatal toxicity effects in SD rats. Therefore, AHAE is potentially harmful to the developing foetuses especially when consumed during the period of implantation and organogenesis. As for the rats treated with 500 mg/kg AHAE, there was no significant treatment-related effect. Hence, we postulate that this finding suggests that the disruption on the hormonal regulation could have been compensated by negative feedback response. The compensated effects of AHAE at 500 mg/kg and the presence of lowest observed adverse effect level (LOAEL) at 250 mg/kg has resulted in a non-monotonous dose response curve (NMDRC), which complicates the determination of the value of no-observed-adverse effect level (NOAEL).

Abstract
Panax quinquefolium L. (American Ginseng, AG) is an herb characteristic for regions of North America and Asia. Due to its beneficial properties it has been extensively investigated for decades. Nowadays, it is one of the most commonly applied medical herbs worldwide. Active compounds of AG are ginsenosides, saponins of the glycosides group that are abundant in roots, leaves, stem, and fruits of the plant. Ginsenosides are suggested to be primarily responsible for health-beneficial effects of AG. AG acts on the nervous system; it was reported to improve the cognitive function in a mouse model of Alzheimer's disease, display anxiolytic activity, and neuroprotective effects against neuronal damage resulting from ischemic stroke in animals, demonstrate anxiolytic activity, and induce neuroprotective effects against neuronal damage in ischemic stroke in animals. Administration of AG leads to inhibition of hypertrophy in heart failure by regulation of reactive oxygen species (ROS) in mice as well as depletion of cardiac contractile function in rats. It also has an anti-diabetic and anti-obesity potential as it increases insulin sensitivity and inhibits formation of adipose tissue. AG displays anti-cancer effect by induction of apoptosis of cancer cells and reducing local inflammation. It exerts antimicrobial effects against several pathogenic strains of bacteria. Therefore, AG presents a high potential to induce beneficial health effects in humans and should be further explored to formulate precise nutritional recommendations, as well as to assess its value in prevention and therapy of some disorders, including cancer.

Abstract
BACKGROUND Korean Red Ginseng has been widely used in traditional oriental medicine for a prolonged period, and its pharmacological effects have been extensively investigated. In addition, Angelica gigas and deer antlers were also used as a tonic medicine with Korean Red Ginseng as the oriental herbal therapy. METHODS This study was conducted to evaluate the potential toxicological effect of KGC-HJ3, Korean Red Ginseng with angelica gigas and deer antlers, on reproductive and developmental functions including fertility, early embryonic development, maternal function, and embryo-fetal development. KGC-HJ3 was administered by oral gavage to Sprague-Dawley rats (22 animals per sex per group) at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on fertility and early embryonic development. In addition, KGC-HJ3 was also administered by oral gavage to mating-proven Sprague-Dawley rats (22 females per group) during the major organogenesis period at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on maternal function and embryo-fetal development. RESULTS AND CONCLUSION No test item-related changes in parameters for fertility, early embryonic development, maternal function, and embryo-fetal development were observed during the study period. On the basis of these results, it was concluded that KGC-HJ3 did not have toxicological potential on developmental and reproductive functions. Therefore, no observed adverse effect levels of KGC-HJ3 for fertility, early embryonic development, maternal function, and embryo-fetal development is considered to be at least 2000 mg/kg/day.

Abstract
Verbena officinalis is widely used by women for maintaining general health and treating various gynaecological disorders during pregnancy. A case report has indicated that the consumption of V. officinalis induced an abortifacient effect. Hence, this study aimed to investigate the prenatal developmental toxicity of this plant according to OECD guideline (no. 414). A total of 50 pregnant female rats (dams) were distributed into five groups (n = 10); 500 mg/kg 1000 mg/2000 mg/kg and 3000 mg/kg of V. offcinalis extracts and the fifth group served as a normal control. All dams received their respective oral single daily treatment from the 6th to the 20th day of gestation. Maternal clinical toxicity signs, body weight and weight gain were recorded. Caesarean sections were performed on day 21 to evaluate embryo-foetal developmental toxicity. For dams, ovaries were harvested and weighed. The number of corpora lutea, implantation sites, and resorptions were recorded. No mortality was observed in dams, but their body weight gain was significantly reduced particularly in dams treated with 2000 and 3000 mg/kg V. officinalis. Asymmetrical distribution of implantation sites and embryos were observed. Embryo-fetotoxicity retardation was observed as evident by the decrease in foetal weight, head cranium, tail length, and higher incidence in the pre-and post-implantation loss. Some foetal skeleton abnormalities such as incomplete ossification of skull, sternebrae, and metatarsal bones were observed in foetuses of the 2000 and 3000 mg/kg V. officinalis-treated dams. LC/MS analysis identified the major constituents including geniposidic acid, tuberonic acid glucoside, luteolin 7, 3'-digalacturonide, iridotrial and apigenin. The glycosylated flavonoids such as apigenin and luteolin could be responsible for the reported prenatal developmental toxicity. In conclusion, the use of V. officinalis during pregnancy is not safe indicating evidence-based toxic effects on the reproductive performance of dams and dose-dependent risk potentials to the foetuses.

Abstract
Background: Self-medication has been increasing in many developing and developed countries. Its use during pregnancy presents a major challenge due to potential undesirable effects on mother and the fetus. So the aim of this study was to assess the prevalence of self-medication and contributing factors, among pregnant women. Methodology: Institution based cross sectional study was conducted among 244 pregnant women attending antenatal care at Hiwot Fana Specialized University Hospital and Jugal Hospital from February to March, 2017. A structured questionnaire based interview was used to collect data from each study subject. Then, data were categorized and analyzed using SPSS version 20 software. Logistic regression analysis was used to determine the significance of the association between the outcome and independent variables. P-value <0.05 was considered as a statistically significant in multivariate analysis. Results: The prevalence of self-medication during current pregnancy was 69.4%; out of which, 40.6% uses only herbal medicines to self-medicate. Time saving (50.7%) and prior experience of the drug (25.35%) were the main reasons for self-medication using conventional medicines while fewer side effects (59.86%) and effectiveness (35.92%) were the common reasons for self-medication using herbal medicines. Common cold and headache were among the common indications for self-medication. Friends (28.17%) and the pharmacist/druggist (23.94%) were the commonest source of information for conventional medicines while family/friends (69.72%) and neighbors (26.76%) were the common source of information for herbal medicines. Community drug retail outlets and neighbors were the commonly used sources of conventional medicines; while market place and self-preparation were the common sources of herbal medicines. Previous history of self-medication was significantly associated (P < 0.05) with current self-medication with conventional drugs and being a farmer by occupation and poor monthly income were significantly associated with herbal medicine use during pregnancy (P < 0.05). Conclusion: The prevalence of self-medication during pregnancy was very high in this study which showed a need for public trainings for all women of reproductive age about the risks of inappropriate self-medication.

Abstract
Ginsenoside Rb1, the major saponin component of ginseng root, has a wide range of therapeutic application. Previous studies have established that ginsenoside Rb1 inhibits the cell cycle and induces apoptosis. However, its side-effects, particularly those on embryonic development, have not been well characterized to date. In the current study, we examined whether ginsenoside Rb1 exerts a cytotoxic effect on mouse embryos at the blastocyst stage, and affects subsequent embryonic development in vitro and in vivo. Blastocysts treated with 25-100 μg mL-1 ginsenoside Rb1 exhibited significantly increased apoptosis and a corresponding decrease in total cell number. Notably, the implantation success rate of blastocysts pretreated with ginsenoside Rb1 was lower than that of their control counterparts. Moreover, in vitro treatment with 25-100 μg mL-1 ginsenoside Rb1 was associated with increased resorption of post-implantation embryos and decreased fetal weight. In an in vivo model, intravenous injection with ginsenoside Rb1 (1, 3, 5 mg kg-1 body weight/day) for 4 days resulted in apoptosis of blastocyst stage embryos and early embryonic developmental injury. In addition, ginsenoside Rb1 appeared to induce injury in mouse blastocysts through oxidative stresses-triggered intrinsic apoptotic signaling processes to impair sequent embryonic development. The collective results strongly indicate that ginsenoside Rb1 induces apoptosis and retards early pre- and post-implantation development of mouse embryos, both in vitro and in vivo. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Coconut oil is commonly used as herbal medicine worldwide. There is limited information regarding its effects on the developing embryo and infant growth. METHODS We investigated the effect of virgin coconut oil post-natally and until 6 weeks old in mice (age of maturity). Females were fed with either standard, virgin olive oil or virgin coconut oil diets 1 month prior to copulation, during gestation and continued until weaning of pups. Subsequently, groups of pups borne of the respective diets were continuously fed the same diet as its mother from weaning until 6 weeks old. Profiles of the standard and coconut oil diets were analysed by gas chromatography flame ionization detector (GCFID). RESULTS Analysis of the mean of the total weight gained/ loss over 6 weeks revealed that in the first 3 weeks, pups whose mothers were fed virgin coconut oil and virgin olive oil have a significantly lower body weight than that of standard diet pups. At 6 weeks of age, only virgin coconut oil fed pups exhibited significantly lower body weight. We report that virgin coconut oil modifies the fatty acid profiles of the standard diet by inducing high levels of medium chain fatty acids with low levels of essential fatty acids. Furthermore, pups borne by females fed with virgin coconut oil developed spiky fur. CONCLUSION Our study has demonstrated that virgin coconut oil could affect infant growth and appearance via maternal intake; we suggest the use of virgin coconut oil as herbal medicine to be treated with caution.

Abstract
BACKGROUND According to World Health Organization (WHO) estimates, 80 % of the population living in rural areas in developing countries depends on traditional medicine for their health needs, including use during pregnancy. Despite the fact that knowledge of potential side effects of many herbal medicines in pregnancy is limited and that some herbal products may be teratogenic, data on the extent of use of herbal medicines by women during pregnancy in the study setting is largely unknown. We determined the prevalence and factors associated with herbal medicine use during pregnancy among women attending postnatal clinics in Gulu district, Northern Uganda. METHODS This was a descriptive cross-sectional study which involved 383 women attending postnatal care across four sites in Gulu district using quantitative and qualitative methods of data collection. A structured questionnaire was used to collect quantitative data while qualitative data were obtained using focus group discussions and key informant interviews. The selection of the study participants was by systematic sampling and the main outcome variable was the proportion of mothers who used herbal medicine. Quantitative data was coded and entered into a computerized database using Epidata 3.1. Analysis was done using Statistical Package for Social Scientists version 13, while thematic analysis was used for qualitative data. RESULTS The prevalence of herbal medicines use during the current pregnancy was 20 % (78/383), and was commonly used in the second 23 % (18/78) and third 21 % (16/78) trimesters. The factors significantly associated with use of herbal medicines during pregnancy were perception (OR 2.18, CI 1.02-4.66), and having ever used herbal medicines during previous pregnancy (OR 2.51, CI 1.21-5.19) and for other reasons (OR 3.87, CI 1.46-10.25). CONCLUSIONS The use of herbal medicines during pregnancy among women in Gulu district is common, which may be an indicator for poor access to conventional western healthcare. Perception that herbal medicines are effective and having ever used herbal medicines during previous pregnancy were associated with use of herbal medicines during current pregnancy. This therefore calls for community sensitization drives on the dangers of indiscriminate use of herbal medicine in pregnancy, as well as integration of trained traditional herbalists and all those community persons who influence the process in addressing the varied health needs of pregnant women.

Abstract
OBJECTIVE To evaluate the prevalence of use of complementary and alternative medicine (CAM) in a Malaysian antenatal population and its impact on obstetric outcome. DESIGN Cross sectional study. SETTING Obstetric Unit, Hospital Sultanah Bahiyah, Alor Setar, Kedah. MATERIAL AND METHOD Women attending antenatal clinic and Patient Admission Centre (PAC) above 30 weeks gestation were given structured questionnaires to fill. Pregnancy outcome measures were documented and analyzed in relation to the information gathered through the questionnaire. SPSS Version 21 was used to analyze all data obtained. RESULTS Out of 447 women, the overall prevalence of CAM usage in pregnancy was 85.2%. It was popular among pregnant mothers aged between 26 and 35 years old and most commonly used in the third trimester (p = 0.0.010) to facilitate labour. Other sociodemographic factors such as race, parity, education, occupation and residence were not significantly important. Traditional herbs was the commonest type of CAM used in pregnancy (58.3%) followed by selusuh (24.3%). About 78.5% of the CAM users delivered vaginally (p = 0.020) but a significant proportion (14.3%) had fetal distress (p = 0.035) compared to non CAM users. The most common type of herbs used was akar kayu bunga Fatimah (37.7%) and gamat (13.4%). In our study, usage of selusuh product and akar kayu bunga Fatimah had a significant impact in achieving vaginal delivery and shortened the duration of labour particularly in multiparae. The usage of Kacip Fatimah and Salindah was associated with preterm labour (p = 0.04)Tongkat Ali herbal coffee had a significant association with hypertensive disorders in pregnancy (p = 0.011) and fetal distress (p = 0.04) Meanwhile, the usage of Jamu Mustika Ratu was significantly associated with low birth weight in grandmultiparae (p = 0.026)and spirulina was significantly associated with oligohydramnios (p = 0.04). CONCLUSION Usage of CAM in pregnancy in the Malaysian population is of high prevalence CAM in pregnancy has beneficial and adverse obstetric outcomes. More research is needed to establish the safety of usage of various forms of CAM in pregnancy.

Abstract
The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of 13 Panax spp root-derived ingredients as used in cosmetics. Panax "spp" indicates that multiple species within the genus are used in cosmetics, but not all species within that genus. Four species are being considered in this safety assessment. These ingredients function mostly as skin-conditioning agents-miscellaneous, fragrance ingredients, skin-conditioning agents-humectant, skin-conditioning agents-emollient, and cosmetic astringents. The Panel reviewed available data related to these ingredients and addressed the issue of pulegone, a constituent of these ingredients and other ingredients, such as peppermint oil. The Panel concluded that these Panax spp root-derived ingredients are safe in the practices of use and concentration as given in this safety assessment.

Abstract
In North America, a high proportion of pregnant women use herbal medications including North American ginseng. This medicinal plant contains high amounts of triterpene saponins (ginsenosides), which are the main bioactive compounds. It is important to assess ginseng’s impact on all reproductive functions to ensure the safety of pregnant women and fetuses. In this study, we defined the concentration-responsive effects of North American alcoholic and aqueous ginseng extracts on preimplantation development in vitro and on pregnancy and post-partum development in the mouse. Two-cell mouse embryos were cultured with 5 different concentrations of whole ginseng root extracts, or ginsenosides Rb1, Rg1 and Re alone, a combinatorial ginsenoside solution and a crude polysaccharide fraction solution. Embryonic development and recovery from each treatment was assessed. To investigate the in vivo effects of ginseng extracts, female mice were gavaged with 50[Formula: see text]mg/kg/day, 500[Formula: see text]mg/kg/day or 2000[Formula: see text]mg/kg/day of either extract (treatment) or water (sham) for 2 weeks prior to mating and throughout gestation. Gestation period, litter size, pup growth and pup sex ratio were evaluated. Oral ginseng consumption did not significantly affect fertility or pregnancy in the mouse. High doses of ginseng (2000[Formula: see text]mg/kg/day) decreased maternal weight gain. Direct treatment of preimplantation embryos in vitro demonstrated that ALC and AQ extract treatment reduced development in a concentration responsive manner, while only ALC extract effects were largely reversible. Treatments with individual or combinatorial ginsenosides, or the polysaccharide fraction solution alone did not impair preimplantation development, in vitro. In conclusion, maternal oral consumption of ginseng has little negative impact on pregnancy in the mouse, however, direct exposure to ginseng extract during mouse preimplantation development in vitro is detrimental.

Abstract
One of the commonly used animal models in fertility, developmental and neurobiological studies is the laboratory rat. The early recognition of rat pregnancy and confirmation of the exact embryonic day are vital. The aim of this study was to investigate the correlation of maternal weight at the time of conception to its increase throughout gestation, aiming to develop a mathematical model, which can be used for the determination of the exact day of pregnancy, set the threshold, and monitor pregnancy from the onset. We studied a total of 173 Wistar rats with a mean body weight of 238.22 ± 34.9 g. After 72 h at the male’s cages, we considered as Day 0 (D0) the day in which a copulatory plug or sperm was found during the vaginal smear examination. After that period the female animals were transferred into their cages, and weight monitoring started 14 days (D14) after D0, until parturition. Based on the statistical analysis, there is a correlation between maternal body weight at D0 and maternal body weight from D14 to D19. Moreover, the average weight gain from D14 to D19 is positively correlated to initial female body weight, while there is no correlation between each pregnant animal’s weight from D14 to D19 and litter size. A mathematical model was developed as a tool for the verification of the day of pregnancy. In conclusion, continuous monitoring of maternal weight after D14 can be a reliable method for the recognition of pregnancy and determination of the exact gestational day.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The increasing use of traditional herbal medicines around the world requires more scientific evidence for their putative harmlessness. To this end, a plethora of methods exist, more or less satisfying. In this post-genome era, recent reviews are however scarce, not only on the use of new "omics" methods (transcriptomics, proteomics, metabonomics) for genotoxicity, teratogenicity, and nephrotoxicity assessment, but also on conventional ones. METHODS The present work aims (i) to review conventional methods used to assess genotoxicity, teratogenicity and nephrotoxicity of medicinal plants and mushrooms; (ii) to report recent progress in the use of "omics" technologies in this field; (iii) to underline advantages and limitations of promising methods; and lastly (iv) to suggest ways whereby the genotoxicity, teratogenicity, and nephrotoxicity assessment of traditional herbal medicines could be more predictive. RESULTS Literature and safety reports show that structural alerts, in silico and classical in vitro and in vivo predictive methods are often used. The current trend to develop "omics" technologies to assess genotoxicity, teratogenicity and nephrotoxicity is promising but most often relies on methods that are still not standardized and validated. CONCLUSION Hence, it is critical that toxicologists in industry, regulatory agencies and academic institutions develop a consensus, based on rigorous methods, about the reliability and interpretation of endpoints. It will also be important to regulate the integration of conventional methods for toxicity assessments with new "omics" technologies.

Abstract
BACKGROUND Despite the vast use of herbal medicines in the world, little is known about their use in pregnancy and the attitudes of pregnant women regarding their safety during pregnancy. OBJECTIVES The aim of this study was to evaluate the use and attitudes of pregnant women toward herbal medicine use in pregnancy in Iran. MATERIALS AND METHODS A questionnaire was completed by 400 women selected by convenience sampling from postnatal and prenatal wards of two hospitals. Data were analyzed using the SPSS software version 13.5. Chi2 test was used to analyze the data. RESULTS The median age was 26.4 (± 5.2) years and the mean number of pregnancies was 1.9 (± 0.98). The use of herbal remedies during pregnancy was positive in 22.3% of patients. They took herbal medicines recommended by their physician (46.1%), through self-medication (44.9%), or with the advice of family members or friends (9%). Additionally, 39.8% believed that it was safe to use herbal remedies during pregnancy, 32.3% believed that it was harmful for both mother and fetus, and 22% did not know whether it was safe or not. CONCLUSIONS Herbal medicine use was not high among our subjects but was significantly affected by age. The level of education, place of living, and number of pregnancies significantly affected the attitudes of the subjects. Women with higher education mostly relied on their own information, whereas those with lower education relied on physician advice. Further educational programs are required to increase the information for this group of susceptible individuals.

Abstract
OBJECTIVE To assess the extent of appropriate counseling provided to patients by pharmacists and nonpharmacists in retail settings regarding herbal dietary supplements for weight loss. DESIGN Descriptive, exploratory, nonexperimental study. SETTING Phoenix, AZ, metropolitan area, from June 2008 to January 2009. PARTICIPANTS Pharmacists and nonpharmacists (e.g., cashiers, sales clerks, pharmacy technicians) working in retail locations selling herbal dietary supplements (e.g., grocery stores, health food stores, pharmacies). INTERVENTION Investigators posing as patients sought herbal weight loss supplement product recommendations and counseling on potential safety, drug interaction, and adverse effect issues from pharmacists or nonpharmacists. MAIN OUTCOME MEASURES Level of knowledge regarding safety and efficacy of herbal dietary supplements for weight loss. RESULTS 52 sites were visited, and 27 unique product recommendations were given. In general, counseling provided to investigators/patients by pharmacists versus nonpharmacists varied significantly (P < 0.05) except when participants were asked about expected weight loss (P = 0.39) or use of herbal supplements during pregnancy (P = 0.07) and breast-feeding (P = 0.48). Pharmacists were more reluctant to recommend herbal products for weight loss than nonpharmacists and tended to question the safety and/or efficacy of these products or refer the patient to an alternate health care provider. CONCLUSION The counseling that investigators/patients received regarding herbal products for weight loss in various retail settings from both pharmacists and non-pharmacists varied greatly. Efforts are needed from the medical and herbal communities to ensure that patients are adequately informed about herbal products at the point of purchase.

Abstract
The numbers of marketing claims and food, beverage, and drug products claiming to increase mental energy have risen rapidly, thus increasing the need for scientific specificity in marketing and food label claims. Mental energy is a three-dimensional construct consisting of mood (transient feelings about the presence of fatigue or energy), motivation (determination and enthusiasm), and cognition (sustained attention and vigilance). The present review focuses on four dietary constituents/supplements (Ginkgo biloba, ginseng, glucose, and omega-3 polyunsaturated fatty acids) to illustrate the current state of the literature on dietary constituents and mental energy. The strongest evidence suggests effects of Ginkgo biloba on certain aspects of mood and on attention in healthy subjects, as well as associations between omega-3 polyunsaturated fatty acids and reduced risk of age-related cognitive decline. Limitations of the current data and challenges for future research are discussed.

Abstract
BACKGROUND Ginseng has been used for a long time and is well tolerated in humans. However, recent studies have shown that ginsenosides Rb1, Rg1, and Re exert embryotoxicity in in vitro culture systems. We investigated the effects of Korean red ginseng extract (KRGE) on embryonic implantation and fetal development in mice. METHODS Mice were orally administered KRGE (20, 200, or 2,000 mg/kg/day) from 2 weeks before mating to gestational day (GD) 18, and implantation rate, fetal mortality, body weights, as well as external, visceral, and skeletal abnormalities were determined by Caesarean section on GD18. Ginsenosides in KRGE and in the blood of dams were identified and quantified by HPLC analysis. RESULTS KRGE did not affect embryonic implantation and mortality as well as fetal body weights up to 2,000 mg/kg/day (approximately 200 times clinical doses), the upper-limit dose recommended by the Korea Food and Drug Administration (KFDA). Although the prevalence of supernumerary ribs increased at the medium dose (200 mg/kg/day), no dose-dependent increases in external, visceral, and skeletal abnormalities were observed. Major ginsenosides such as Rb1, Rg1, and Re were not detected in the blood of dams based on their chromatographic profiles. CONCLUSIONS Considerable developmental toxicities of KRGE, even at the upper-limit dose, were not observed in mice. These results might be due to the negligible blood concentrations of ginsenosides in their original forms following oral administration, suggesting that in vitro experiments to assess the effects of ginsenosides on embryotoxicity may not reliably explain the risks of ginsenosides to in vivo embryo-fetal development.

Abstract
Ginseng is one of the most widely used herbal medicines and is reported to have a wide range of therapeutic and pharmacological applications. Ginsenosides, the major pharmacologically active ingredients of ginseng, appear to be responsible for most of the activities of ginseng including vasorelaxation, antioxidation, anti-inflammation and anti-cancer. Approximately 40 ginsenoside compounds have been identified. Researchers now focus on using purified individual ginsenoside to reveal the specific mechanism of functions of ginseng instead of using whole ginseng root extracts. Individual ginsenosides may have different effects in pharmacology and mechanisms due to their different chemical structures. Among them the most commonly studied ginsenosides are Rb1, Rg1, Rg3, Re, Rd and Rh1. The molecular mechanisms and medical applications of ginsenosides have attracted much attention and hundreds of papers have been published in the last few years. The general purpose of this update is to provide information of recently described effects of ginsenosides on antioxidation, vascular system, signal transduction pathways and interaction with receptors. Their therapeutic applications in animal models and humans as well as the pharmacokinetics and toxicity of ginsenosides are also discussed in this review. This review concludes with some thoughts for future directions in the further development of ginseng compounds as effective therapeutic agents.

Abstract
The effect of ginsenosides on proliferation of type A spermatogonia was investigated in 7-day-old mice. Spermatogonia were characterized by c-kit expression and cell proliferation was assessed by immunocytochemical demonstration of proliferating cell nuclear antigen (PCNA). After 72-h culture, Sertoli cells formed a confluent monolayer to which numerous spermatogonial colonies attached. Spermatogonia were positive for c-kit staining and showed high proliferating activity by PCNA expression. Ginsenosides (1.0 approximately10 microg/ml) significantly stimulated proliferation of spermatogonia. Activation of protein kinase C (PKC) elicited proliferation of spermatogonia at 10(-8) to 10(-7) mol/L and the PKC inhibitor H(7) inhibited this effect. Likewise, ginsenosides-stimulated spermatogonial proliferation was suppressed by combined treatment of H(7). These results indicate that the proliferating effect of ginsenosides on mouse type A spermatogonia might be mediated by a mechanism involving the PKC signal transduction pathway.

Abstract
BACKGROUND Using Chinese herbal medicines during pregnancy and postpartum is common in the Chinese community. OBJECTIVE The purpose of this current study is to explore the use of Chinese herbal medicines by women during pregnancy and postpartum in Taiwan. DESIGN It is an on-going prospective longitudinal study design. SETTING AND PARTICIPANTS We used multistage stratified systematic sampling to recruit 24,200 pairs, postpartum women and newborns, from the Taiwan national birth register in 2005. Subjects underwent a home interview 6 months after their deliveries between June 2005 and July 2006. A structured questionnaire was successfully administered to 87.8% of the sampled population. RESULTS At least one Chinese herbal medicine was used by 33.6% and 87.7% of the interviewed subjects during pregnancy and the postpartum period, respectively. An-Tai-Yin, Pearl powder, and Huanglian were the most commonly used during pregnancy, while Shen-Hua-Tang and Suz-Wu-Tang were the most commonly used by postpartum women. Pregnant women aged 20-34, with high education, threatened abortion, chronic disease, and primipara appeared to use more Chinese herbal medicines than others in the sample. Postpartum women with high education, primipara, normal spontaneous delivery, and breastfeeding were found to use more Chinese herbal medicines; but women with pregnancy-related illness used less. CONCLUSIONS Chinese herbal medicines are frequently used by women during pregnancy and the postpartum period in Taiwan and those with high education and primipara used more such herbs. Due to limited safety information on these herbs, we would advise caution regarding their use either during pregnancy or postpartum breastfeeding period. Moreover, it is important for nurses/midwifes enquiring about such habits, and providing the adequate education to women during prenatal and postpartum care to prevent potential side effects.

Abstract
PURPOSE To study characteristics of women using herbal drugs and the possible impact of use in early pregnancy on pregnancy outcome. METHODS Data on the use of herbal drugs during pregnancy were obtained from the Swedish Medical Birth Register during the period 1st July 1995 to end of 2004. Women who reported use of herbal drugs were compared to all women giving birth during the period. Outcome variables were prematurity, birth weight, Apgar score, number of infants in delivery and congenital malformations. RESULTS Among the 860 215 women in the register, 787 (0.9%) reported use of herbal drugs during early pregnancy. The most frequently used herbal drugs were Floradix (iron-rich herbs), ginseng and valerian. Use of such drugs was independently associated with high maternal age, normal weight and 14-15 years of education. Risk factors for valerian differed from those for other herbal drugs, for example with respect to maternal smoking and country of birth. Concomitant drug use was common and the most frequently used drugs were multivitamins, folic acid, cardiovascular drugs (mainly antihypertensive drugs), non-steroid anti-inflammatory drugs (NSAIDs), analgesics and psycholeptics. None of the infant characteristics studied were influenced significantly by the mother's use of the examined herbal drugs during early pregnancy. CONCLUSIONS The most commonly reported herbal drugs used during pregnancy were Floradix (iron-rich herbs), ginseng and valerian. No signs of unfavourable effect on pregnancy outcome were seen. The number of exposures, however, was low and therefore effects on rare outcomes (e.g. specific malformations) cannot be excluded.

Abstract
Ginseng has beneficial effects on the cardiovascular system, but its underlying mechanism is unclear. This study investigated the effects of ginsenoside Rb1, a major constituent of ginseng, on the changes of lactate dehydrogenase (LDH) activity, nitric oxide (NO), tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor-1 (PAI-1) in oxidized low-density lipoprotein (oxLDL)-injuring endothelial cells. Human umbilical vein endothelial cells were cultured and divided into 6 groups (n = 6): control group, oxLDL alone group (100 mg/L), ginsenoside Rb1 alone group (10 microg/mL), oxLDL plus ginsenoside Rb1 groups (0.1, 1.0, and 10 microg/mL, respectively.). Twenty-four hours after treatment, LDH activity and concentrations of NO, t-PA, and PAI-1 in culture medium were measured while the expressions of endothelial nitric oxide synthase (eNOS), t-PA, and PAI-1 mRNA in endothelial cells were detected by reverse-transcriptase polymerase chain reaction. Compared with control group, oxLDL (100 mg/L) caused LDH activity, the expressions of eNOS and t-PA mRNA, and concentrations of NO and t-PA to significantly decrease (P < 0.05, respectively), and it also led to dramatic increase of PAI-1 mRNA and concentration (P < 0.05, respectively). Ginsenoside Rb1 alone did not demonstrate this ability. High-dose Rb1 (10 microg/mL) could block the effects of oxLDL on LDH activity, mRNA of eNOS, t-PA, and PAI-1, and concentrations of NO, t-PA, and PAI-1 (P < 0.05, respectively), and neither low-dose Rb1 (0.1 microg/mL) nor medium-dose Rb1 (1.0 microg/mL) demonstrated this ability. We conclude that ginsenoside Rb1 has protective effects on oxLDL-injuring human vascular endothelial cells and can reverse the effects of oxLDL on NO, t-PA, and PAI-1.

Abstract
Tea is the most common beverage after water. Concerns have been raised about the safety of tea during pregnancy, especially for embryo development. We aimed at studying the effects of active tea components on developing embryos by in vitro rat embryo culture. Rat embryos during early organogenesis were cultivated in serum supplemented with one of the tea catechins. Developmental hallmarks and malformations (Mal) in the developing embryos were compared and evaluated by a standard morphological scoring system. The embryotoxicity of each tea catechin was classified according to the European Center for the Validation of Alternative Methods. Cell viability was assessed by supervital dye staining, apoptosis by TUNEL assay, and peroxidation by the 8-isoprostane EIA method. We found that (+)-catechin had the least effect on developing embryos (Mal(50)=715.1 mg/L; IC50(Mal)=435 mg/L), whereas (-)-epigallocatechin gallate had the most adverse effect (Mal(50)=54.2 mg/L; IC50(Mal)=45.8 mg/L). The major malformation in affected embryos included caudal retardation with abnormal axial flexion and delayed hind-limb formation. All catechins were classified as nonembryotoxic except (-)-epigallocatechin gallate, which was classified as weakly embryotoxic. With (-)-epigallocatechin gallate, increased numbers of nonviable and apoptotic cells in the malformed embryos were associated with increased embryo 8-isoprostane.

Abstract
BACKGROUND Major congenital malformations place a considerable burden on the affected child, the family and society. Any kind of medicine used during pregnancy might have a harmful impact; therefore, such practice has raised concerns. The objective of the current study was to explore the relationship between the use of herbal medicines by pregnant women during the first trimester of pregnancy and the risk of major congenital malformation in their live born infants. METHODS This was a cross-sectional analysis of data from a prospective pregnancy cohort, which was established between 1984 and 1987. To assemble the cohort, pregnant women of >or=26 weeks of gestation who came to the Taipei Municipal Maternal and Child Hospital in Taiwan for prenatal care were enrolled in the study and interviewed using a structured questionnaire. Detailed information, including herbal medicine use during different periods of pregnancy, was obtained during the interview. Past medical history, current obstetric data and details on conventional medicines used during pregnancy were abstracted from medical records. Data on birth weight, gestational duration and characteristics of live born infants were gathered from the Taiwan national birth register. Congenital malformation information was obtained from multiple sources: the newborn examination record (1984-7); the national death register (1984-2003); and Taiwan National Health Insurance data (1996-2000). Multiple logistic regression was used to estimate the odds ratio [OR] of major congenital malformation by herbal medicines used during the first trimester. RESULTS A total of 14,551 live births were analysed. After adjustment for confounding factors, taking huanglian during the first trimester of pregnancy was found to be associated with increased risk of congenital malformations of the nervous system (adjusted OR 8.62, 95% CI 2.54, 29.24). An-Tai-Yin was associated with an increased risk of congenital malformations of the musculoskeletal and connective tissues (adjusted OR 1.61, 95% CI 1.10, 2.36) and the eye (adjusted OR 7.30, 95% CI 1.47, 36.18). CONCLUSION We found evidence for a possible link between the use of specific herbal medicines during the first trimester of pregnancy and increased risks of specific groups of congenital malformations. We could not investigate whether the adverse effects were related to direct toxicity from the herbal medicines, or were from misuse, contamination or uncontrolled confounding. Nonetheless, we would advise caution regarding use of herbal medicines during pregnancy, and we suggest that further investigation of these findings is warranted.

Abstract
OBJETIVO: Verificar com que freqüência medicamentos e\ou drogas fitoterápicas que interferem na coagulação sangüínea são utilizados por pacientes que serão submetidos à intervenção cirúrgica e cujo uso não é relatado ao cirurgião; ou quando este é informado não se recomenda a sua interrupção antes da operação. MÉTODO: Estudo quantitativo com variáveis qualitativas, transversal, sobre o uso de medicamentos (AAS e Vitamina E) e fitoterápicos (Ginkgo biloba, Alho, Ginseng e Gengibre) por parte de 416 pacientes em programação pré-operatória. Desenvolvido no Hospital Universitário de Taubaté (HUT) no Hospital Regional de Taubaté (HRT) e em um Consultório Particular de Cirurgia Plástica. Estes dados foram obtidos por meio de questionário com perguntas relacionadas ao uso ou não das drogas referidas no último ano e nos 10 dias que antecediam a operação, se o cirurgião foi informado do fato e se houve recomendação médica para a sua suspensão. RESULTADOS: do total pesquisado 58,89% não fizeram uso de alguma das drogas em questão, 39% as usaram no último ano e 13,83% usaram nos últimos 10 dias. O AAS foi o medicamento mais utilizado e dentre os fitoterápicos, o Ginkgo biloba. Do total pesquisado 73,69% dos pacientes não informaram ao cirurgião o uso destas drogas. CONCLUSÕES: Na população estudada é elevada a porcentagem do uso de drogas que interferem na coagulação sanguínea, sendo as mais utilizadas o AAS, a vitamina E e o Ginkgo biloba. A maioria dos pacientes pesquisados não informou ao cirurgião a sua utilização. Deve-se enfatizar a necessidade de pesquisar o uso dessas drogas no pré-operatório, com o objetivo de reduzir possíveis complicações hemorrágicas per e pós-operatórias, pelas suas complicações médicas e eventuais implicações legais.

Abstract
PURPOSE To explore the effect of Coptidis Rhizoma on foetal growth in pregnancy. METHODS During 1985-1987, each pregnant woman with 26 or more weeks of gestation who came to the Taipei Municipal Maternal and Child Hospital for prenatal care was enrolled and interviewed by three trained interviewers using structured questionnaires to obtain detailed information including the herbal medicines used during pregnancy. Medical histories of diabetes, hypertension, antepartum haemorrhage and medicines used during pregnancy were abstracted from medical records of mothers'. Data of birth weight, gestational duration and characteristics of infants were gathered from the Taiwan national birth registration. A total of 9,895 singleton livebirths were analysed. The variables related to foetal growth included two dichotomous measures: low birth weight (LBW) and small for gestational age (SGA); and one continuous measure: birth weight. Potential risk factors associated with these outcomes were investigated using multiple logistic and linear regression models. RESULTS After adjustment, pregnant women taking Coptidis Rhizoma during pregnancy had no significantly adverse effect on foetal growth. There was a non-significantly slightly decreased mean of birth weight and increased risk of LBW and SGA babies if the frequency of using Coptidis Rhizoma was more than 56 times. CONCLUSIONS The usual usage of Coptidis Rhizoma during pregnancy seemed not to increase the adverse risk on foetal growth. Future observations for use of longer than 56 times or a higher cumulated dose were needed to clarify the safety.

Abstract
GRg1 is one of the most important active agents extracted from ginseng. Although there are numerous reports in the medical literature concerning the beneficial effects of GRg1, little is known about its effects on embryonic development. In our study, whole embryo culture was applied to explore the effects of GRg1 on SD rat and ICR mouse embryos during their critical period of organogenesis. All embryos were exposed to different concentrations of GRg1, and scored for their growth and differentiation at the end of the 48-h culture period. Total morphological score decreased significantly at the concentration of GRg1 of 50 microg/ml to mice and at 30 microg/ml to rats. The whole embryonic growth was affected, represented as reduced crown-rump length and head length, and decreased number of somites from 10 microg/ml both in mice and rats. Morphological development was influenced relatively late. To rats, the scores of flexion, forelimb bud and hindlimb bud were significantly reduced at 30 microg/ml, and heart was among the affected organs. However, the effect on heart was not observed in mice, and flexion and limb buds were influenced at 50 microg/ml. These results demonstrate that GRg1 has embryotoxicity during both rat and mouse organogenetic period and rats might be more sensitive than mice. We suggest that pregnant women of first trimester should use ginseng with caution before the exact conclusion is obtained.

Abstract
BACKGROUND Ginseng has been widely used around the world for many years. Knowledge is limited, however, on its effects on embryonic development. METHODS Whole embryo culture was used to explore the developmental toxicity of ginsenoside Rb1 (GRb1) on mouse embryos. All embryos were exposed to different concentrations of GRb1, and scored for their growth and differentiation at the end of the 48-hr culture period. RESULTS Total morphological score decreased significantly at the concentration of GRb1 of 30 microg/ml and was further reduced at 50 microg/ml. Yolk sac was affected at the lower concentration of 15 microg/ml. Developments of midbrain, forebrain, and optic system were relatively sensitive to GRb1 and were affected at the concentration of 30 microg/ml. Allantois, flexion, branchial arch, and limb buds were affected at 50 microg/ml. At this concentration, the embryonic crown-rump length, head length, and somite number were also reduced significantly compared to the control group. CONCLUSIONS These results suggest that GRb1 has teratogenic effect during the mouse organogenetic period. We suggest that before more data in humans is available, ginseng should be used with caution by pregnant women in the first trimester.

Abstract
The safety of different doses of Kan Jang--a fixed combination of Andrographis paniculata special extract (SHA-10) and Acanthopanax senticosus--compared to two extensively used medicinal plants, Valeriana officinalis and Panax ginseng in the form of standardized extracts, has been examined. A phase I clinical study was designed to evaluate the effect on semen quality of healthy males in terms of spermatogenesis and quality of semen. The results of the study revealed no significant negative effect of Kan Jang on male semen quality and fertility, but rather a positive trend with respect to the number of spermatozoids in the whole ejaculate, the percentage of active (normokinetic) forms of spermatozoids, and fertility indexes, together with a decrease in the percentage of inactive (diskinetic) forms of spermatozoids. In the group receiving ginseng, no significant negative effects on the fertility parameters were revealed and there was a clear decrease in the percentage of diskinetic forms of spermatozoids. Subjects receiving valerian showed a temporary increase in the percentage of normokinetic spermatozoids and a decrease in diskinetic forms, but these changes had no effect on fertility indices. The results indicate that Kan Jang, ginseng and valerian are safe with respect to effects on human male sterility when administered at dose levels corresponding to approximately 3 times the human daily dose.

Abstract
BACKGROUND Pregnant women commonly consume ginseng. However, there is little data concerning the effects of ginseng on early pregnancy. METHODS Rat embryos were exposed in vitro to different concentrations of Rc and Re from day 9.5 to day 11.5 after conception. Embryos were scored for growth and differentiation at the end of the culture period. RESULTS Embryos exposed to 50.0 microg/ml Re had significantly lower median morphological score (29.0 versus 48.0), fewer number of somites (15.0 versus 21.0), and smaller yolk sac diameter (3.5 versus 4.1 mm) and crown-rump length (CRL) (2.9 versus 3.4 mm) compare to control embryos. There was no significant difference between embryos exposed to 5.0 microg/ml Re and control embryos. There was also no difference in the biometric and morphologic parameters among control and embryos exposed to 5.0 and 50.0 microg/ml Rc. CONCLUSION There is a significant variability in embryotoxic effects of different ginsenosides. Further studies to evaluate the synergistic embryotoxic effects of ginsenosides are warranted.

Abstract
We studied the estrogenic activity of a component of Panax ginseng, ginsenoside-Rb1. The activity of ginsenoside-Rb1 was characterized in a transient transfection system, using estrogen receptor isoforms and estrogen-responsive luciferase plasmids, in COS monkey kidney cells. Ginsenoside-Rb1 activated both alpha and beta estrogen receptors in a dose-dependent manner with maximal activity observed at 100 microm, the highest concentration examined. Activation was inhibited by the estrogen receptor antagonist ICI 182,780, indicating that the effects were mediated through the estrogen receptor. Treatment with 17beta-estradiol or ginsenoside-Rb1 increased expression of the progesterone receptor, pS2, and estrogen receptor in MCF-7 cells and of AP-1-driven luciferase genes in COS cells. Although these data suggest that it is functionally very similar to 17beta-estradiol, ginsenoside-Rb1 failed to displace specific binding of [(3)H]17beta-estradiol from estrogen receptors in MCF-7 whole-cell ligand binding assays. Our results indicate that the estrogen-like activity of ginsenoside-Rb1 is independent of direct estrogen receptor association.
