Herbal medicine use during pregnancy in a group of Australian women

Prevalence of herbal medicine use and associated factors among pregnant women attending antenatal care at public health facilities in Hossana Town, Southern Ethiopia: facility based cross sectional study

Background

The use of herbal medicine has been on increase in many developing and industrialized countries. More pregnant women use herbal remedies to treat pregnancy related problems due to cost-effectiveness of therapy and easy access of these products. We sought to assess the prevalence of herbal medicine use and associated factors among pregnant women attending antenatal clinics of public health facilities.

Methods

Facility based cross sectional study was conducted among 363 pregnant women attending antenatal clinics from May to June 2015 at public health facilities in Hossana town, Hadiya zone, Southern Ethiopia. Pretested structured questionnaire was used to collect data from each study subject. Bivariate logistic regression analysis was used to see significance of association between the outcome and independent variables. Odds ratios at 95 % CI were computed to measure the strength of the association between the outcome and the independent variables. P-value <0.05 was considered as a statistically significant in multivariate analysis.

Result

Two hundred fifty eight (73.1 %) of pregnant women used herbal medicine during current pregnancy . The herbal medicines commonly taken during current pregnancy were ginger (55.8 %), garlic (69.8 %), eucalyptus (11.6 %), tenaadam (rutachalenssis) (26.4 %), damakesse (ocimumlamiifolium) (22.8 %), feto (3.5 %) and omore (3.1 %). Being students (AOR: (5.68, 95 % CI: (1.53, 21.13), second trimester of pregnancy (AOR: 0.22, 95 % CI: (0.08, 0.76), sufficient knowledge on herbal medicine (AOR: 0.37, 95 % CI: (0.19, 0.79), no formal education (AOR: 4.41, 95 % CI: (1.11, 17.56), primary education (AOR: 4.15, 95 % CI: (1.51, 11.45) and secondary education (AOR: 2.55, 95 % CI: (1.08,6.03) were significantly associated with herbal medicine use.

Conclusion

The findings of this study showed that herbal medicine use during pregnancy is a common experience. Commonly used herbal medicines during current pregnancy were garlic, ginger, tenaadam, damakasse and eucalyptus. Educational status, occupation, knowledge on herbal medicine and second trimester of pregnancy were the major factors affecting use of herbal medicine. Health education about the effects of herbal medicine on pregnancy should be given during antenatal care sessions and through media. Health care providers, especially those that are involved in antenatal care should aware of evidence regarding potential benefits or harm of herbal medicinal agents when used by pregnant women.

Treatment of nausea in pregnancy: a cross-sectional multinational web-based study of pregnant women and new mothers

BACKGROUND

The factors related to the treatment of nausea during pregnancy have not yet been investigated in several countries simultaneously. The present study aimed to describe differences in self-reported nausea during pregnancy and the patterns of use for both conventional and herbal medicines across countries. The factors related to nausea and its treatment and the relationships between different self-reported co-morbidities and nausea were also investigated.

METHODS

This cross-sectional study used data collected by a web-based questionnaire distributed between October 2011 and February 2012 in several countries within five regions: Western, Northern, and Eastern Europe, North America, and Australia. Women who were pregnant or had a child less than one year old were eligible to participate.

RESULTS

A total of 9113 women were included in the study, whereof 6701 (73.5%) had experienced nausea during pregnancy. Among respondents with nausea, conventional medicines were used by 1201 (17.9%) women and herbal medicines by 556 (8.3%) women. The extent of self-reported nausea and its treatment varied by country. Education, working status, and folic acid use were significantly associated with the use of conventional medicines against nausea. Respondents who had nausea also had a high burden of co-morbidity.

CONCLUSION

The prevalence of nausea was high across all participating countries but its treatment varied, possibly due to cultural differences and differences in attitudes towards medicines. A high degree of co-morbidity was found among respondents with nausea.

Consumption of Chinese herbal medicines during pregnancy and postpartum: A prospective cohort study in China

OBJECTIVE

to investigate usage patterns and factors associated with maternal consumption of Chinese herbal medicines in China.

DESIGN

prospective cohort study. Information on the use of Chinese herbal medicines was collected from mothers by personal interview at hospital discharge and followed up by telephone at one, three and six months postpartum.

SETTING

seven hospitals in Jiangyou, Sichuan Province of China.

PARTICIPANTS

695 mothers who gave birth to a singleton infant.

MEASUREMENTS

prevalence, type, frequency and duration of herbal medicine usage. Logistic mixed regression analyses were performed to determine factors affecting the use.

FINDINGS

a total of 43.5% and 45.0% of mothers consumed Chinese herbal medicines during pregnancy and postpartum, respectively. Angelica sinsensis was the most popular herbal medicine among the participants (pregnancy 28.8%, postpartum 26.8%). Although herbal medicines were taken more regularly by postpartum users, the median usage duration varied from two to three months during pregnancy but 1-1.6 months postpartum. The majority of users (pregnancy 42.9%, postpartum 55.1%) were advised by their mother or mother-in-law to take Chinese herbal medicines. Antenatal alcohol drinking (adjusted odds ratio 2.75, 95% confidence interval 1.01-7.53) was associated with a marginally higher prevalence of herbal consumption during pregnancy, whereas mothers with a lower family income (adjusted odds ratio 1.52, 95% confidence interval 1.12-2.04) were more likely to consume Chinese herbal medicines in the postpartum period.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

consumption of Chinese herbal medicines appears to be prevalent among Chinese mothers, especially those drinking alcohol whilst pregnant and women from a lower income household. Maternity health professionals need to be aware of the lack of evidence to support the use of Chinese herbal medicines during pregnancy and postpartum, and to provide their clients with scientifically based advice regarding herbal medicine use.

"Natural" relief of pregnancy-related symptoms and neonatal outcomes: above all do no harm

ETHNOPHARMACOLOGICAL RELEVANCE

In the South of Italy the use of herbal remedies to alleviate pregnancy-related symptoms is very common.

OBJECTIVES

To investigate the proportion, prevalence of use, attitude and knowledge base in a sample of Italian pregnant women in the South of Italy. To explore the possible influence and risks of herbal consumption on pregnancy and neonatal outcomes.

METHODS

A retrospective observational study was conducted during the study period November 2010-September 2013. Six hundred and thirty expectant mothers were interviewed within three days after childbirth in a public Hospital in the South of Italy.

RESULTS

Due to a lack of data, a total of six hundred interviews were considered. Four hundred and eighty six women (81%) reported to have constantly used at least one herbal product throughout the pregnancy period. The study enrolled mostly women between 31 and 40 years of age, with a middle-high level of education, married and employed. The most commonly used herbal products, taken by oral route and for the entire period of pregnancy, were chamomile, fennel, propolis, cranberry, lemon balm, ginger, valerian and mallow. The most relevant source of information for the majority of participants was the doctor (95%), and most of the women (72%) informed their doctors about their use of herbal remedies.

CONCLUSIONS

The regular chamomile consumption resulted in a higher risk of pre-term delivery, lower birth weight and lower length of the newborn. Also a regular use of fennel resulted in a shorter gestational age. Finally, ginger intake resulted in a shorter gestational age and in a smaller circumference of the newborn's skull.

A randomized controlled trial comparing Pentazocine and Chamomilla recutita for labor pain relief

BACKGROUND

Traditional birth attendants in Pakistan sometimes use a homeopathic remedy, Chamomilla for labor pain relief. Our study compares this homeopathic remedy for pain relief in labor with a commonly used parenteral analgesic in a hospital setting. No systematic study has been conducted previously to study the effect of chamomile, which may be affordable and available in community settings.

METHODS

A double blind randomized controlled trial was carried out at Islamic International Medical College Trust. Ninety-nine normal pregnant women were randomly assigned into three groups. Each group received one of the three trial drugs; Chamomile, Pentazocine or placebo. The efficacy of labor analgesia was assessed by using Visual Analogue Scale (VAS) for pain intensity. Indicators of maternal and child health were recorded as were adverse effects of the drugs.

RESULTS

Mean pain scores in the three groups were calculated and compared. The difference in mean VAS scores in Pentazocine and Chamomilla recutita group as compared with placebo was not statistically significant. No significant adverse effects were noticed in any group except slight headache and dizziness in three parturients in Pentazocine group.

CONCLUSION

Neither Pentazocine, or Chamomilla recutita offer substantial analgesia during labor.

A survey and analysis of using traditional Chinese medicine during pregnancy

BACKGROUND

The usage of Traditional Chinese Medicine (TCM) during pregnancy is very common for Chinese people. However, there are only a few studies relevant to the usage of TCM during pregnancy-providing very little knowledge on the benefits or harmful effects of these medicines to pregnant women or the fetus.

OBJECTIVES

The purpose of this study is to survey the current situation of TCM usage during pregnancy, and to explore the factors that affect the use of TCM.

METHODS

Data was collected from pregnant patients who delivered in our hospital, from March 2012 to August 2012. All patients who agreed to join this study were asked to fill-up a questionnaire.

RESULTS

1,010 patients were willing to participate in this study. 11.2% (113, 1,010) of patients used at least one kind of TCM during pregnancy. The average TCM usage is 2.1 species. The most commonly used drugs are Antai pill (39 cases, 34.5%), Xiaochaihu granules (31 cases, 27.4%), and Shengxuening tablets (23 cases, 20.4%). Patients who smoke during pregnancy (OR=1.8, 95% CI: 0.7~5.1), drink during pregnancy (OR=1.6, 95% CI: 0.4~6.1), have been hospitalized during pregnancy (OR=4.8, 95% CI: 2.9~7.9), have pregnancy complications (OR=2.7, 95% CI: 1.5~4.9) and those who are infertile (OR=2.6, 95% CI: 1.4~4.8) have higher chances of using TCM during pregnancy.

CONCLUSIONS

Pregnant women commonly use TCM during pregnancy. Pregnant women who smoke, drink, hospitalized during pregnancy, experience pregnancy complications and infertility are more likely to use TCM.

Herbal Medicines Use During Pregnancy: A Review from the Middle East

The prevalence of the herbal medicines use is on the rise across the world, especially amongst pregnant women. The scenario in the Middle Eastern region was reviewed to explore the prevalence, usage pattern, motivation, and attitude towards use of herbal medicine by pregnant women. Literature published up to December 2012 showed the prevalence of herbal medicine use varied between 22.3-82.3%, implying a rising trend in the utilization of herbal medicine during pregnancy. The most common herbs used were peppermint, ginger, thyme, chamomile, sage, aniseed, fenugreek, and green tea. The most common reasons for use included the treatment of gastrointestinal disorders and cold and flu symptoms. The majority of women used these products during their first trimester, and did not reveal this information to their physician. Most women were advised by family and friends to use herbal medicines and believed they were more effective and had fewer side effects than modern medicine especially during pregnancy. In conclusion, the use of herbal medicine is prevalent among pregnant women in the Middle Eastern region and healthcare providers need to seek information pertaining to their use.

What Do Breastfeeding Women Taking Herbal Galactagogues Perceive of Community Pharmacists' Role in Breastfeeding Support? A Qualitative Study

Information from pharmacists may affect breastfeeding womens’ decisions and choice of therapy. Community pharmacies remain one of the main sources of herbal medicines in Australia. In this study, we aimed to explore the perspectives of breastfeeding women on pharmacists’ role and whether there is potential for role expansion, as well as the facilitators and barriers in meeting their healthcare-related needs in the community pharmacy setting. Semi-structured in-depth interviews were conducted with 20 Western Australian women who were using one or more herbal galactagogues while breastfeeding. Participants’ views were classified into three major themes: (i) facilitators and (ii) barriers to an increased role of pharmacists; and (iii) implementation of breastfeeding related-services in community pharmacy settings. Overall perspectives of participants were positive about the potential for role expansion of pharmacists to meet their breastfeeding-related needs. Whilst most participants perceived community pharmacies as convenient sources of trusted information, some recognised barriers to an increased role of pharmacists. Several breastfeeding support services perceived to be useful in community pharmacy settings were identified. Issues raised highlighted areas of pharmacy practice which required improvement and revealed opportunities for expansion of pharmacists’ role to better support women and promote breastfeeding in the community.

Safety of Popular Herbal Supplements in Lactating Women

The increasing popularity and use of dietary supplements has required health care professionals to become more knowledgeable of their properties, interactions, and adverse effects. The objectives of this review were to evaluate the safety of popular dietary supplements in breastfeeding mothers and the effects on the infants. Nine of the most popular herbal dietary supplements were identified based on the 2011 US market report of the top 10 selling botanicals and the most frequently received inquiries by the Ruth A. Lawrence Lactation Study Center at the University of Rochester Medical Center. Relevant publications were identified through June 2014 using PubMed and EMBASE; tertiary references, including the Drugs and Lactation Database and Natural Medicine Comprehensive Database, were also reviewed. These herbals include black cohosh, cranberry, echinacea, evening primrose, garlic, ginseng, melatonin, milk thistle, and St John's wort. Studies varied greatly with regard to study design, herbal intervention, and outcome measures. Findings suggested that dietary/herbal supplements have not been evaluated in high-quality clinical trials, and there is limited evidence supporting safety of use, particularly among lactating women. Therefore, it is essential for physicians to provide counseling for nursing mothers seeking information on dietary supplements, highlighting reliable safety profiles, inquiring about the potential benefits the patient is seeking, and assessing the patient's perception of this supplement during breastfeeding. More research and clinical trials are required in this area to guide the recommendations and expand our current knowledge of these products.

Women's Use and Self-Prescription of Herbal Medicine during Pregnancy: An Examination of 1,835 Pregnant Women

BACKGROUND

Recent research points to high levels of herbal medicine use during pregnancy. The objectives of this study were to elucidate the prevalence and understand the determinants of both the use and self-prescription of herbal medicine during pregnancy.

METHODS

The study sample was obtained via the Australian Longitudinal Study on Women's Health. Women who were pregnant or who had recently given were invited to complete a subsurvey in 2010 about pregnancy, and complementary and alternative medicine use.

FINDINGS

A response rate of 79.2% (n=1,835) was attained and 34.4% (n=588 of 1,835) of the sample were utilizing herbal medicine during pregnancy, of which 77.9% (n=458 of 588) were self-prescribing these products. The women in our study (aged 33-38) were more likely to use herbal medicine if they had anxiety (odds ratio [OR], 1.30; 95% CI, 1.02-1.64; p=.031), sleeping problems (OR, 1.55; 95% CI, 1.15-2.11; p=.005), or fatigue (OR, 1.32; 95% CI, 1.04-1.68; p=.025), but less likely to use herbal medicine if they had nausea (OR, 0.71; 95% CI, 0.56-0.91; p=.007). Women were more likely to self-prescribe herbal medicine if they suffered from varicose veins (OR, 2.46; 95% CI, 1.04-5.84; p=.041) and less likely to self-prescribe herbal medicine if they suffered from preeclampsia (OR, 0.23; 95% CI, 0.81-0.63; p=.005). Women who self-prescribed herbal medicine during pregnancy were also more likely to live in a rural environment (OR, 2.22; 95% CI, 1.32-3.73; p=.003).

CONCLUSIONS

Many Australian women are consuming herbal medicine during pregnancy. The self-prescription of herbal medicine by pregnant women is of particular concern owing to potential safety issues, and it is important that maternity health care providers have an open and nonjudgmental conversation with women about herbal medicine use during pregnancy.

PURPOSE

This study aims to evaluate the prevalence and the factors related to the use of herbs by women during pregnancy, childbirth, postpartum and for infant healthcare. The study also aims to identify the herbs therapeutic uses and preparation. To date, no previous studies have investigated this prevalence in Palestine.

METHODS

A cross-sectional survey of women of different child-bearing age group inhabiting different locations in Palestine was carried out by means of a semi-structured questionnaire.

RESULTS

A total of 372 women were interviewed. Of the participants 72.3% reported using herbs at different pregnancy stages and for infant healthcare. The most common herbal products used in this study at different stages of pregnancy were Pimpinella anisum, Salvia fruticosa, Matricaria aurea, and Mentha spicata.

CONCLUSION

This study revealed that there is an appreciable prevalence of herbal use among pregnant women at different pregnancy stages and for infant healthcare in Palestine.

Use of herbal medicine among pregnant women on antenatal care at nekemte hospital, Western ethiopia

Background:

Investigations across the world confirm dramatic increment in the use of complementary and alternative medicine in pregnant women. The most important aspect is lack of awareness of pregnant women about potential effects of using traditional medicine on fetus; some herbal products may be teratogenic in human and animal models. In this area, so far, no research has been conducted in Ethiopia to assess traditional medicine use in pregnant women.

Objectives:

Therefore, the main objective of this study was to investigate the prevalence and use of herbal drugs among pregnant women attending Nekemte Hospital to provide baseline information for future studies.

Patients and Methods:

A cross-sectional descriptive study was conducted by quantitative and qualitative approaches to identify the prevalence of using herbal medicines among pregnant women. About 50.4% of study participants used herbal drugs during their pregnancy. The proportion of herbal drug usage was gradually decreased along with the first, second and third trimesters of pregnancy. The most and least commonly used herbs were ginger (44.36%) and tenaadam (9.15 %), respectively. The common indications of herbal remedies use during pregnancy were nausea (23.90%) and morning sickness (21.05%).

Results:

The result of the present study confirmed wide use of herbal drugs use during pregnancy that need to report the safety concerns of these drugs during pregnancy.

Conclusions:

To achieve the requirements of pregnant women, it is vital for health care workers to be familiar with the effect of herbal medicine in pregnancy.

Pregnancy outcomes, embryonic and fetal development in maternal exposure to Chinese medicines

Chinese medicine is a common name for a collection of Chinese Materia Medica with therapeutic properties for medical treatment and healing. Similar to Western pharmaceuticals, Chinese medicines are not free of risk, and have the potential to cause adverse pregnancy outcomes and affect embryonic and fetal development. However, most clinical data concerning safety of maternal exposure to Chinese medicines during pregnancy are not available and the conclusion remains elusive. Some individual clinical trials of Chinese medicines reported some minor adverse effects during pregnancy, whereas few animal studies identified some adverse maternal and perinatal effects, as well as embryotoxic potentials. Basic research and mechanistic studies of the teratogenicity of Chinese medicines are still lacking. There is an urgent need for testing the safety of Chinese medicines before recommendation and commercialization. Until more reliable and scientific research data become available, clinicians should consider both the risks and benefits before recommending Chinese medicines to pregnant women. More systematic investigations of the safety implications of the use of Chinese medicines are highly recommended, in addition to more clinical trials with a larger sample size to confirm its safety during pregnancy. This review includes a critical overview of available clinical and experimental data and provides directions to study the safety issue of Chinese medicines for pregnancy.

Herbal therapies in pregnancy: what works?

PURPOSE OF REVIEW

The aim of this article is two-fold: to report the prevalence of herbal products used by pregnant women and to evaluate the evidence of efficacy and safety of the most popular remedies.

RECENT FINDINGS

Of the 671 articles identified, 15 randomized controlled trials (RCTs) and 16 non-RCTs were eligible. Ginger was the most investigated remedy and it was consistently reported to ameliorate nausea and vomiting in pregnancy. Although raspberry, blue cohosh, castor oil, and evening primrose oil are believed to facilitate labor in traditional medicine, very few scientific data support such indication. Moreover, they have been associated with severe adverse events. Data on the safety of Hypericum perforatum in pregnancy or lactation are reassuring, whereas efficacy was demonstrated only in nonpregnant individuals. There is still insufficient evidence regarding the efficacy and safety of Echinacea, garlic, and cranberry in pregnancy.

SUMMARY

Epidemiological studies reported a wide range of use of herbal remedies in pregnancy. Too few studies have been devoted to the safety and efficacy of singular herbs. With the exception of ginger, there are no consistent data to support the use of any other herbal supplement during pregnancy. Severe adverse events have been reported using blue cohosh and evening primrose oil.

Echinacea and elderberry-should they be used against upper respiratory tract infections during pregnancy?

This review evaluates the safety of echinacea and elderberry in pregnancy. Both herbs are commonly used to prevent or treat upper respiratory tract infections (URTIs) and surveys have shown that they are also used by pregnant women. The electronic databases PubMed, ISI Web of Science, AMED, EMBASE, Natural Medicines Comprehensive Database, and Cochrane Library were searched from inception to November 2013. Relevant references from the acquired articles were included. No clinical trials concerning safety of either herb in pregnancy were identified. One prospective human study and two small animal studies of safety of echinacea in pregnancy were identified. No animal- or human studies of safety of elderberry in pregnancy were identified. Twenty clinical trials concerning efficacy of various echinacea preparations in various groups of the population were identified between 1995 and 2013. Three clinical trials concerning efficacy of two different elderberry preparations were identified between 1995 and 2013. The results from the human and animal studies of Echinacea sp. are not sufficient to conclude on the safety in pregnancy. The prospective, controlled study in humans found no increase in risk of major malformations. The efficacy of Echinacea sp. is dubious based on the identified studies. Over 2000 persons were given the treatment, but equal amounts of studies of good quality found positive and negative results. All three clinical trials of Elderberry concluded that it is effective against influenza, but only 77 persons were given the treatment. Due to lack of evidence of efficacy and safety, health care personnel should not advice pregnant women to use echinacea or elderberry against upper respiratory tract infection.

Herb use, vitamin use, and diet in low-income, postpartum women

INTRODUCTION

Little is known about herb use among underserved postpartum women and their patterns of communication about herb use with prenatal providers.

METHODS

We interviewed women from the postpartum unit at an urban hospital about herb use during pregnancy, socioeconomic factors, prenatal vitamin use, and diet. We asked women if they discussed use of herbs and vitamins with their prenatal care providers and asked about their satisfaction with these discussions. We reviewed inpatient chart medication lists for herb use.

RESULTS

Of 160 women surveyed, 39% reported using herbs during pregnancy. Sixty-five percent of participants took a prenatal vitamin. Fifty-seven percent of herb users (n = 40) reported taking prenatal vitamins. Herb users were significantly more likely to report making any dietary change during their pregnancies than non-herb users (P = .03). Only 38% of herb users discussed it with their prenatal providers, and 82% were satisfied with the conversation. Of all 160 participants, 125 had prenatal vitamin use documented, and no women had herbal medicine use documented in the medical record during their birth hospitalization.

DISCUSSION

We report a higher frequency of herb use during pregnancy than other studies. The fact that women of all backgrounds and economic statuses report using herbs during pregnancy makes it even more important for all women to be asked about their use of herbs.

Herbal medicine use in pregnancy: results of a multinational study

BACKGROUND

The use of complementary and alternative medicines (CAM) is growing in the general population. Herbal medicines are used in all countries of the world and are included in the top CAM therapies used.

METHODS

A multinational study on how women treat disease and pregnancy-related health ailments was conducted between October 2011 and February 2012 in Europe, North and South America and Australia. In this study, the primary aim was to determine the prevalence of herbal medicine use in pregnancy and factors related to such use across participating countries and regions. The secondary aim was to investigate who recommended the use of herbal medication in pregnancy.

RESULTS

There were 9,459 women from 23 countries participating in the study. Of these, 28.9% reported the use of herbal medicines in pregnancy. Most herbal medicines were used for pregnancy-related health ailments such as cold and nausea. Ginger, cranberry, valerian and raspberry were the most commonly used herbs in pregnancy. The highest reported rate of herbal use medicines was in Russia (69%). Women from Eastern Europe (51.8%) and Australia (43.8%) were twice as likely to use an herbal medicine versus other regions. Women using herbal medicines were characteristically having their first child, non-smokers, using folic acid and consuming some alcohol in pregnancy. Also, women who were currently students and women with an education other than a high school degree were more likely to use herbal medicines than other women. Although 1 out of 5 women stated that a physician had recommended the herbal use, most women used herbal medicine in pregnancy on their own initiative.

CONCLUSIONS

In this multinational study herbal medicine use in pregnancy was high although there were distinct differences in the herbs and users of herbal medicines across regions. Most commonly the women self-medicated with herbal medicine to treat pregnancy-related health ailments. More knowledge regarding the efficacy and safety of herbal medicines in pregnancy is warranted.

Pregnancy outcome after use of cranberry in pregnancy--the Norwegian Mother and Child Cohort Study

Background

Cranberry is one of the most commonly used herbs during pregnancy. The herb has been used traditionally against urinary tract infections. No studies are found that specifically address the risk of malformations after use of cranberry during pregnancy. The aim of the study was to investigate the safety of cranberry use during pregnancy, including any effects on congenital malformations and selected pregnancy outcomes.

Methods

The study is based on data from The Norwegian Mother and Child Cohort Study including more than 100,000 pregnancies from 1999 to 2008. Information on use of cranberry and socio-demographic factors was retrieved from three self-administered questionnaires completed by the women in pregnancy weeks 17 and 30, and 6 months after birth. Information on pregnancy outcomes was retrieved from the Medical Birth Registry of Norway.

Results

Among the 68,522 women in the study, 919 (1.3%) women had used cranberry while pregnant. We did not detect any increased risk of congenital malformations after use of cranberry. Furthermore, the use of cranberry was also not associated with increased risk for stillbirth/neonatal death, low birth weight, small for gestational age, preterm birth, low Apgar score (<7), neonatal infections or maternal vaginal bleeding in early pregnancy. Although an association was found between use of cranberry in late pregnancy and vaginal bleeding after pregnancy week 17, further sub-analyses of more severe bleeding outcomes did not support a significant risk.

Conclusions

The findings of this study, revealing no increased risk of malformations nor any of the following pregnancy outcomes; stillbirth/neonatal death, preterm delivery, low birth weight, small for gestational age, low Apgar score and neonatal infections are reassuring. However, maternal vaginal bleeding should be investigated further before any firm conclusion can be drawn. Treatment guidelines on asymptomatic bacteriuria in pregnancy recommend antimicrobial therapy as the first line treatment. According to our data and the outcomes studied, cranberry does not appear to be a harmful adjunctive self-treatment.

The use of herbal medicines during breastfeeding: a population-based survey in Western Australia

BACKGROUND

Main concerns for lactating women about medications include the safety of their breastfed infants and the potential effects of medication on quantity and quality of breast milk. While medicine treatments include conventional and complementary medicines, most studies to date have focused on evaluating the safety aspect of conventional medicines. Despite increasing popularity of herbal medicines, there are currently limited data available on the pattern of use and safety of these medicines during breastfeeding. This study aimed to identify the pattern of use of herbal medicines during breastfeeding in Perth, Western Australia, and to identify aspects which require further clinical research.

METHODS

This study was conducted using a self-administered questionnaire validated through two pilot studies. Participants were 18 years or older, breastfeeding or had breastfed in the past 12 months. Participants were recruited from various community and health centres, and through advertising in newspapers. Simple descriptive statistics were used to summarise the demographic profile and attitudes of respondents, using the SPSS statistical software.

RESULTS

A total of 304 questionnaires from eligible participants were returned (27.2% response rate) and analysed. Amongst the respondents, 59.9% took at least one herb for medicinal purposes during breastfeeding, whilst 24.3% reported the use of at least one herb to increase breast milk supply. Most commonly used herbs were fenugreek (18.4%), ginger (11.8%), dong quai (7.9%), chamomile (7.2%), garlic (6.6%) and blessed thistle (5.9%). The majority of participants (70.1%) believed that there was a lack of information resources, whilst 43.4% perceived herbal medicines to be safer than conventional medicines. Only 28.6% of users notified their doctor of their decision to use herbal medicine(s) during breastfeeding; 71.6% had previously refused or avoided conventional medicine treatments due to concerns regarding safety of their breastfed infants.

CONCLUSIONS

The use of herbal medicines is common amongst breastfeeding women, while information supporting their safety and efficacy is lacking. This study has demonstrated the need for further research into commonly used herbal medicines. Evidence-based information should be available to breastfeeding women who wish to consider use of all medicines, including complementary medicines, to avoid unnecessary cessation of breastfeeding or compromising of pharmacotherapy.

Use of herbal medicines during pregnancy in a group of Palestinian women

ETHNOPHARMACOLOGICAL RELEVANCE

The use of herbal medicines during pregnancy is common worldwide due to physiological changes that lead to pregnancy related problems.

OBJECTIVES

The aims of this study were to measure the prevalence and predictors of herb use among a group of Palestinian pregnant women and the possible influence of herbal consumption on pregnancy outcomes.

METHODS

This study was a questionnaire-based cross sectional descriptive study. It was conducted in the maternity ward of a governmental hospital between March and May 2012, a random sample of women who gave birth during the study period were met and asked to answer a face to face questionnaire.

RESULTS

Out of 300 women, 120 women (40.0%) used herbs during pregnancy; most women preferred to use herbs because they thought herbs are safer than medications (82.5%), women based in their choices mainly on advice from family or doctors (36.7%, 33.0%, respectively), 65.8% of them told their doctors that they used herbs, 91.7% considered these therapies beneficial, and 99.2% reported no side effects. The most commonly used herbs were anise (Pimpinella anisum) (61.7%), chamomile (Matricaria recutita) (53.3%), sage (Salvia officinalis) (55%), mixture of herbs (33.3%), and thyme (Thymus vulgaris) (29.2%). Most women were using herbs on as needed bases. There were no statistically significant differences between users and non-users of herbs in all socio-demographic variables and pregnancy outcomes.

CONCLUSIONS

This study found that the use of herbs during pregnancy is very common among Palestinian women. Infrequent use of herbs during pregnancy seems to be safe and beneficial. To provide the best care to pregnant women who use herbal products, clinicians and pharmacist are recommended to stay up to date with herb use and their safety in pregnancy. Not all women tell their doctors about herbal products use, so the physicians are recommended to ask pregnant women about this to avoid any possible negative outcomes on the mother or the fetus.

The influence of complementary and alternative medicine use in pregnancy on labor pain management choices: results from a nationally representative sample of 1,835 women

OBJECTIVES

This study examines involvement with a range of complementary and alternative medicine (CAM) during pregnancy on the use of pharmacologic (PPMT) and nonpharmacologic (NPMT) pain management techniques for labor and birth.

DESIGN

Longitudinal analysis of survey data.

PARTICIPANTS

A substudy (n=2445) of the "young" cohort of the nationally representative Australian Longitudinal Study on Women's Health was conducted.

OUTCOME MEASURES

Use of PPMT and NPMT during labor and birth.

RESULTS

The survey was completed by 1835 women (response rate, 79.2%). Most respondents used either intrapartum PPMT (81.9%) or NPMT (74.4%). Many (60.7%) used some form of CAM during pregnancy and also used PPMT during birth. More than two thirds of women (66.7%) who used NPMT used CAM during pregnancy. There was a general trend of increased likelihood of NPMT use by women who applied CAM during pregnancy. There was an inverse effect on use of epidural analgesia for women who consumed herbal teas during pregnancy (odds ratio, 0.60).

CONCLUSIONS

Because of the study design, this paper does not confirm a causative relationship between the use of CAM during pregnancy and intrapartum pain management choices. It does, however, indicate that the use of CAM during pregnancy may not significantly affect the uptake of intrapartum PPMT, despite possible attempts to reduce PPMT by using NPMT. It also highlights the possibility of potential interactions between CAM and PPMT, given the high prevalence of concomitant use.

Women's use of complementary and alternative medicines during pregnancy: a cross-sectional study

OBJECTIVE

to determine the prevalence of women's use of complementary and alternative medicines (CAM) during pregnancy in the UK, reasons for use, who recommended CAM, and the characteristics of women that are associated with use of CAM during pregnancy.

DESIGN

cross-sectional questionnaire.

SETTING

Birmingham Women's Hospital.

PARTICIPANTS

315 postnatal women were surveyed while on the postnatal ward.

FINDINGS

the questionnaire response rate was 89% (315/355). CAM use during pregnancy was reported by 180 women (57.1%). CAM users differed significantly from non-CAM users by education level, parity and previous CAM use before pregnancy. Vitamins (34.9%), massage therapy (14.0%), yoga (11.1%) and relaxation (10.2%) were the most commonly reported uses of CAM. 33.0% of women reported they did not disclose their use of CAM to a doctor or midwife, and 81.3% were not asked by their doctor or midwife about their use of CAM during pregnancy.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

this study found a high prevalence of CAM use during pregnancy, which is within the range of findings of studies from Australia and Germany. It is important that health-care providers routinely ask about CAM use during pregnancy and are able to provide pregnant women with appropriate advice regarding CAM use.

Safety of ginger use in pregnancy: results from a large population-based cohort study

PURPOSE

The objective of the study was to examine the safety of ginger use during pregnancy on congenital malformations and selected pregnancy outcomes.

METHODS

The Norwegian Mother and Child Cohort study, a large population-based cohort, provided the data used in this study. Our study population consisted of 68,522 women. Data on ginger use and socio-demographic factors were retrieved from three self-administered questionnaires completed by the women during weeks 17 and 30 of the pregnancy and when their child was 6 months old. Data on pregnancy outcomes were provided by the Medical Birth Registry of Norway.

RESULTS

Among the 68,522 women in the study, 1,020 (1.5 %) women reported using ginger during pregnancy. The use of ginger during pregnancy was not associated with any increased risk of congenital malformations. No increased risk for stillbirth/perinatal death, preterm birth, low birth weight, or low Apgar score was detected for the women exposed to ginger during pregnancy compared to women who had not been exposed.

CONCLUSION

Use of ginger during pregnancy does not seem to increase the risk of congenital malformations, stillbirth/perinatal death, preterm birth, low birth weight, or low Apgar score. This finding is clinically important for health care professionals giving advice to pregnant women with NPV.

Herb remedies during pregnancy: a systematic review of controlled clinical trials

OBJECTIVE

The use of herbal remedies has been documented both among various patient groups and in the general population to promote health. The aim of this systematic review is to analyze the benefits of herb use during pregnancy.

METHODS

A systematic literature search covering the period from January 1990 to September 2010 was performed using various electronic databases. Randomized controlled clinical trials (RCTs) were included. Paper quality was evaluated using the Jadad scale.

RESULTS

Of the 511 articles identified, 14 RCTs were eligible. Ginger was the most investigated remedy and was consistently reported to ameliorate nausea and vomiting during pregnancy better than placebo; its efficacy in doing so was noted to be equal to that of vitamin B6 and dimenhydrinate. A single trial also supported the use of Hypericum perforatum for wound healing. Cranberry, however, was not efficacious in the treatment of urinary tract infections; finally, raspberry leaf did not shorten the first stage of labor, and garlic did not prevent pre-eclampsia.

CONCLUSIONS

Despite the widespread, popular use of herbal remedies during pregnancy, too few studies have been devoted to specific clinical investigations. With the exception of ginger, there is no data to support the use of any other herbal supplement during pregnancy.

Use of and attitudes toward complementary and alternative medicine among midwives in Turkey

OBJECTIVE

The objective of the study was to evaluate the use of and attitudes toward complementary and alternative medicine (CAM) among midwives in Turkey.

STUDY DESIGN

Information was requested from 129 midwives at family health centers in Samsun concerning their suggestions for the use of complementary and alternative medicine for pregnant women.

RESULTS

58.9% of the midwives in this study had suggested CAM methods to pregnant women. It was found that, among CAM methods, the midwives studied made use of herbal treatment, diets and exercises the most (32.6%, 27.9% and 28.7%, respectively) and acupuncture, relaxation techniques and fast walking the least (1.6%, 6.2%, and 7.0%, respectively). It was found that the CAM method most suggested by the midwives studied was herbal therapy, and this therapy was suggested for nausea-vomiting, anemia, gastralgic complaints, constipation, sore throat, insomnia, hypertension, sinusitis, cough, the common cold, stress, hemorrhoids and asthenia-fatigue.

CONCLUSION

Complementary and alternative medicine, especially herbal therapy, is commonly suggested to pregnant women by those midwives studied in Samsun.

The role of naturopathy in pregnancy, labour and post-natal care: broadening the evidence-base

It is known that women are high users of complementary and alternative medicine (CAM) including naturopathy and that CAM is frequently used by pregnant women. However, we still know little about the consumption, practice and role of naturopathy in pregnancy, labour and post-natal care. With this in mind, this paper proposes a possible framework for advancing further research on this topic. The framework is divided into issues associated with three core stakeholder groups - pregnant women, naturopaths/herbalists and other maternity health professionals including obstetricians, midwives and general practitioners. The development of a rigorous health services research agenda around this topic has much to offer maternity-care users, practitioners and policy makers and the framework outlined here is offered with the hope of inspiring further inquiry into this significant issue in women's health.

Medication use during pregnancy in Omani women

OBJECTIVE

The aim of this study was to evaluate medication use pattern in a university tertiary hospital in the Sultanate of Oman.

SETTING

The study was conducted at the Sultan Qaboos University Hospital (SQUH) and the SQUH Family and Community Medicine clinic (FAMCO), Muscat, Sultanate of Oman during 7th to 25th June 2008.

METHOD

The medication use pattern was evaluated in women attending FAMCO and the standard antenatal clinics at the hospital. Women were interviewed in different gestational ages using a structured questionnaire. The Electronic Patient Record (EPR) was reviewed to acquire additional information on medication use. Medications were classified according to the US FDA risk classification.

MAIN OUTCOME MEASURE

Medication used including prescribed medications, OTC medications, or herbal treatment during the current pregnancy and 3 months prior to conception.

RESULTS

The study included a total of 139 pregnant mothers with an overall mean age of 28 ± 5 years ranging from 19 to 45 years. There was a slight overall reduction in the medication use including prescribed medications. However, there was a significant increase in utilization of vitamins and supplements (84-95% vs. 12% in the 3-months prior, P < 0.001) as well as herbal preparations (16-19% vs. 7% in the 3-months prior, P = 0.011) throughout pregnancy (P < 0.010). The use of category A medications increased in all trimester (43-52% vs. 13% in the 3 months prior, P < 0.010) while a reduction in the use of category C (for first and third trimester, P < 0.050) and D medications was seen. A reduction in the use of teratogenic drugs in all trimesters (P < 0.010) was also observed.

CONCLUSION

The prescribing of vitamins and minerals was optimal. However, the common use of herbal supplements observed warrants special attention due to their unknown risks. The conclusions should be interpreted in light of the study's limitations.

Evaluating the Impact of a Pragmatic Nutrition Awareness Program for Expectant Mothers upon Birth Weight of the Newborn

Poor maternal nutritional status and substandard antenatal care, which result in increased women's risk, low birth weight and stillbirth, afflict many countries with weak or emerging economies even today. Studies that address the effect of extending nutrition awareness among pregnant women to the net outcome of pregnancy remain scarce. We aimed to compare and contrast the effect of a pragmatic nutrition awareness program for expectant mothers (NAPEM) on birth weight of the newborn with a control group who received no such nutrition awareness activity. The effect of variables of mode of newborn delivery, associated complications at birth, and APGAR score of the newborn were also assessed. A pragmatic intervention trial of an antenatal care (ANC) program that consisted in nutrition awareness was conducted involving 53 pregnant women. Awareness was given through one-to-one interview and through informational literature provided to the participants in the local language. A hospital registry for deliveries undertaken during the study period was screened for identification of variables. A control group of matched pregnant women (n = 53) was obtained from the same hospital registry from preceding years, when the nutrition awareness program was not executed. A statistically significant improvement in birth weight of the newborn was observed in the intervention group, where expectant mothers were made aware about desired nutrition during pregnancy. A reduced incidence of complications associated with pregnancy was also observed in the intervention group. Providing awareness about nutritional requirements during pregnancy and suggesting the pragmatic ways to meet them was shown to be one possible effective measure to deal with pregnancy-related undernutrition. We show the efficacy of the intervention for underprivileged regions of India marked by inadequate health care delivery and lower socio-economical standards. We discuss our findings in the context of available evidence-based guidelines.

Use of herbal products among 392 Italian pregnant women: focus on pregnancy outcome

PURPOSE

The present study aimed to explore the use of herbal products among a sample of Italian pregnant women and the possible influence of herbal consumption on pregnancy outcome.

METHODS

The study was conducted over a 10-month period (2 days a week, from January to October 2009) at the Maternity wards of Padua and Rovereto Hospital. Data were collected through a face-to-face interview on the basis of a prestructured questionnaire including socio-demographic characteristics of the enrolled subjects, specific questions on herbal use, information about pregnancy and newborn.

RESULTS

In total, 392 interviews were considered. One hundred and nine out of 392 women (27.8%) reported to have been taking one or more herbal products during pregnancy, in the 36.7% of cases throughout all pregnancy. The most frequently herbs taken by interviewees were chamomile, licorice, fennel, aloe, valerian, echinacea, almond oil, propolis, and cranberry. Four out of 109 women (3.7%) reported side-effects: constipation after a tisane containing a mix of herbs, rash and itching after local application of aloe or almond oil. The decision to use herbal products was mainly based on personal judgement and on the conviction that these natural substances would be safer than traditional medicines. Users were more often affected by morbidities pregnancy-related and their neonates were more frequently small for their gestational age. An higher incidence of threatening miscarriages and preterm labours was observed among regular users of chamomile and licorice.

CONCLUSIONS

This research underlines that the use of herbal products during pregnancy is common among Italian women, not always appropriate and in some cases potentially harmful.

The use of complementary and alternative medicine by pregnant women: a literature review

BACKGROUND

The use of complementary and alternative medicine (CAM) has become increasingly prevalent in industrialised countries, with women being the most prolific users. Some women continue to consume these therapies when they become pregnant.

AIM

To review the literature exploring prevalence and motivation for use of complementary and alternative medicine by pregnant women.

METHOD

A search for relevant literature published from 2001 was undertaken using a range of databases and by examining relevant bibliographies.

RESULTS

Although the estimates vary widely from 1% to 87%, the general trend indicates that a significant number of pregnant women use complementary and alternative medicine. Common modalities used include massage, vitamin and mineral supplements, herbal medicine, relaxation therapies and aromatherapy. Reasons for use are varied and include the belief that these therapies offer safe alternatives to pharmaceuticals, they allow greater choice and control over the childbearing experiences, and they are congruent with their holistic health beliefs. The influence of traditional cultural practices on the use of these therapies is unclear. Most expectant women rely on advice from family and friends, and many do not disclose their use to their pregnancy care providers.

CONCLUSIONS

Many women use complementary and alternative medicine when they are pregnant. Further research is needed to gain a greater understanding of the true prevalence and expectant women's motivation for the use of complementary and alternative medicine. Health-care professionals are encouraged to ask women about their use of these treatments and seek out relevant information.

Use, Attitudes and Knowledge of Complementary and Alternative Drugs (CADs) Among Pregnant Women: a Preliminary Survey in Tuscany

To explore pregnant women's use, attitudes, knowledge and beliefs of complementary and alternative drugs (CADs) defined as products manufactured from herbs or with a natural origin. A preliminary survey was conducted among 172 pregnant women in their third trimester of pregnancy, consecutively recruited in two obstetrical settings; 15 women were randomly selected to compute a test-to-retest analysis. Response rate was 87.2%. Test-to-retest analysis showed a questionnaire's reproducibility exceeding a K-value of 0.7 for all items. Mean age was 32.4 ± 0.4 years; most women were nulliparae (62.7%). The majority of subjects (68%) declared to have used one or more CADs during their lifetime; 48% of pregnant women reported taking at least one CAD previously and during the current pregnancy. Women's habitual use of CADs meant they were at higher risk of taking CADs also during pregnancy (adjusted odds ratio = 10.8; 95% confidence interval: 4.7-25.0). Moreover, 59.1% of the subjects were unable to correctly identify the type of CADs they were using. The majority of women resorted to gynecologists as the primary information source for CADs during pregnancy, while they mainly referred to herbalists when not pregnant. Habitual use of CADs seems to be a strong predictor for their ingestion also during pregnancy; in addition most subjects were unable to correctly identify the products they were taking. In the light of the scanty data concerning the safety of CADs during pregnancy, these preliminary results confirm the need to investigate thoroughly the situation of pregnant women and CADs consumption.

Effects in Rats of Maternal Exposure to Raspberry Leaf and Its Constituents on the Activity of Cytochrome P450 Enzymes in the Offspring

The goal of our study was to determine whether maternal exposure to red raspberry leaf (RRL) and its constituents can permanently alter biotransformation of fluorogenic substrates by cytochrome P450 (CYP) in the livers of male and female offspring. Nulliparous female rats received vehicle, raspberry leaf, kaempferol, quercetin, or ellagic acid orally once breeding had been confirmed until parturition. Hepatic microsomes were prepared from animals at birth (postnatal day 1 [PND1]), weaning (PND21), PND65, and PND120 to determine the biotransformation of 8 fluorogenic substrates. The pattern of biotransformation of all but 2 of the substrates was gender specific. Maternal consumption of RRL increased biotransformation of 3 substrates by female offspring at PND120 resulting in a more masculine profile. Kaempferol and quercetin had a similar effect to RRL. These results suggest that maternal consumption of either RRL or some of its constituents leads to long-term alterations of CYP activity in female offspring.

Use of herbal drugs during pregnancy among 600 Norwegian women in relation to concurrent use of conventional drugs and pregnancy outcome

PURPOSE

The purpose of this study was to investigate the use of herbal drugs by pregnant women in relation to concurrent use of conventional drugs, delivery, and pregnancy outcome.

METHOD

600 women at Stavanger University Hospital Norway were interviewed using a structured questionnaire within five days after delivery. Medical birth charts were reviewed with respect to pregnancy outcome.

RESULTS

In all, 39.7% of the women reported having used herbal drugs during pregnancy, most commonly ginger, iron-rich herbs, echinacea and cranberry. Although 86.3% of the women reported having used conventional drugs during pregnancy there were few potential interactions between herbal drugs and conventional drugs. There was a significant association between the use of iron-rich herbs during pregnancy and high birthweight, and use of raspberry leaves and caesarean delivery.

CONCLUSION

Use of herbal drugs is common during pregnancy and indicates a need for documentation about their safety in pregnancy.

The use during pregnancy of prescription, over-the-counter, and alternative medications among Hispanic women

BACKGROUND

Despite lack of scientific evidence about the safety of complementary and alternative medicines, the reported use of such remedies during pregnancies has increased. This study was undertaken to investigate the use of herbs, vitamins, and over-the-counter and prescription medications among pregnant Hispanic women and reasons for use, and to assess physician-patient level of communication about women's use.

METHODS

A total of 485 Hispanic women were surveyed by means of a self-administered questionnaire immediately postpartum in a public hospital in Houston, Texas. The primary outcome was use of alternative therapies during the prenatal period.

RESULTS

During their pregnancies, 19 percent of the participants took herbs and 47 percent took vitamin supplements, other than prenatal vitamins. The most common reason for using herbs and vitamins was to improve the woman's general health and energy level (59%); a few women (12%) had used them for specific pregnancy-related problems. Overall, 77 percent took prenatal vitamins and 21 percent supplemented with folic acid. The rates of use of over-the-counter and prescription medications were 23 and 29 percent, respectively. The use of prescription medication was two-and-a-half times higher among women with history of medical problems (adjusted OR = 2.59, 95% CI = 1.59-4.25, p = 0.0001). No other factor studied was independently associated with supplement or medication use. One in five women (20%) believed that herbs and vitamins were safer to use than prescription medication or were better at treating medical problems than prescription medicine, and one-third had not disclosed information about supplement use to their physicians.

CONCLUSIONS

Use of herbal remedies does not appear to be a replacement for conventional medicine among most pregnant Hispanic women. Patient education about the risks of alternative therapies may lead to a reduction in intake of alternative medicines and greater disclosure to medical practitioners among this ethnic group.

Use of herbal treatments in pregnancy

OBJECTIVE

Interest in herbal treatments has increased without data on safety, efficacy, or rates of use in pregnancy. We examined antenatal herbal and natural product use among mothers of nonmalformed infants in 5 geographic centers.

STUDY DESIGN

We used data on nonmalformed infants from the Slone Epidemiology Center's case-control surveillance program for birth defects to examine rates and predictors of herbal use. Exposures were identified through maternal interview. In addition to overall use, 5 categories based on traditional uses and 2 natural product categories were created; topical products and herbal-containing multivitamins were excluded.

RESULTS

Among 4866 mothers of nonmalformed infants, 282 (5.8%) reported use of herbal or natural treatments. Use varied by study center and increased with increasing age.

CONCLUSION

Although rates of use are low, there remains a need for investigation of the safety of these products. Given sparse data on efficacy, even small risks might well outweigh benefits.
