Abstract
Traditional medicine has the potential to boost the health and economies of many SSA countries, especially if regulatory mechanisms are deployed to govern their protection and utilisation. There is lack of knowledge regarding traditional medicines and their impact on pregnancy. This paper reviews the literature on traditional medicine utilisation among pregnant women in Sub-Saharan African countries. The paper, determined the proportion of pregnant women utilising traditional medicines in Sub-Saharan Africa, identified the different types of traditional medicine used during antenatal care and reasons for Use in Sub-Saharan Africa and also identified challenges that are faced by women who use traditional medicine in antenatal care. A systematic exploratory review was conducted guided by the PRISMA framework. The databases that were searched included Google Scholar, PubMed, Cochrane, HINARI and the World Health Organization. Forty-one literature sources were eligible and included in the review process. Reported traditional medicine utilisation ranged between 12 and 93% among pregnant women in Sub-Saharan Africa. Different types of traditional medicines have been utilised in Sub-Saharan Africa for different purposes. Safety and poor management of usage were reported to be some of the challenges associated with traditional medicine. There is a need to determine chemical components and mode of action of these herbs as some could be beneficial, whilst others harmful, leading to severe pregnancy complications.
1) Traditional medicine utilisation during pregnancy is common in many Sub-Saharan African (SSA) countries.
2) There are still gaps in knowledge on how traditional medicine is utilised and for what purposes during pregnancy
3) This research provides a window of opportunity to explore the different types of traditional medicines utilised in different countries in SSA and document these for possible further studies to explore its safety and efficacy to strengthen health systems in managing pregnancies.
Background
Traditional medicines (TM) have been used in pregnancy management in many countries, even where modern health care is readily available 1 TM refers to plants, animals, or minerals taken either by injection, ingestion, adsorption or absorption by pregnant women 2 It focuses on the knowledge, skills and practices based on the theories, beliefs and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health and the prevention, diagnosis, improvement or treatment of physical and mental illnesses 2 There has been an increase of interest in the use and importance of TMs both by the WHO and many African countries 3 Pregnant women utilise TMs for several reasons: lack of foetal turning, overdue delivery, pregnancy breech and false labour, morning sickness, abdominal pain, constipation, heartburn, uterus being dirty or full of air, sexually transmitted diseases and high blood pressure4,5 The utilisation of TMs is diverse in maternal health. It can be used for different purposes depending on individuals the culture and beliefs of individuals and is based on locally available natural resources 6 The use is triggered by various practices, approaches, knowledge and beliefs about incorporating plant, animal and mineral-based medicines, spiritual therapies to maintain wellbeing and treat, diagnose or prevent illness2,7,8 However, it is reported in some studies that this increasing Use of TMs by pregnant women poses risks which in most cases are unknown ad could compete with other modernised medicines used, leading to complications 9
Treatment in the early stages of pregnancy is believed to prevent miscarriage and ensure proper growth of the foetus and stability of the woman’s health10,11 Treatment with TM at the later stages of pregnancy ensures safe delivery minimising chances of complications even after birth 12 Though most professional health practitioners are sceptical about the safety of TM usage, they agree that traditional healers play an important complementary role in the provision of effective prevention and treatment of diseases 13 The African continent is still developing, and several countries are classified as poor by the World Bank14,15 Poverty has negatively impacted health service provision due to poor infrastructure development and human resources exodus to developed countries16–18 Staff shortages in health institutions, among other challenges, have ensured that traditional health practitioners serve a large population and play an essential role in the health system19–21 There should, therefore, be an urgent need to recognise traditional practitioners and prioritise them in public health campaigns and health promotions as a mechanism to reduce maternal mortality 2 Studies in Sub-Saharan Africa (SSA) have shown that doctors are fewer than traditional healers aiding pregnant women to consult with the traditional system, which is more efficient2,22,23 Apart from the challenges mentioned above, sociocultural factors such as the knowledge passed from generation to generation, availability of TMs, unpleasant experiences with the formal health system, health beliefs and conceptualisation in most Africa settings also influence traditional medicine use in pregnant women SSA 4
Generally, several studies conducted on TMs utilisation tend to focus mainly on the factors that lead women to utilise the different types of TMs, with most focussing on the proportions of pregnant women that utilise these medicines during pregnancy9,24–28 Furthermore, most of these studies do not explore in-depth the challenges reported by these women who utilise TMs thus, this current study is critical in ensuring that challenges faced by women who utilise TMs are comprehensively documented through synthesising the different studies that have been published in SSA.
TM can boost the health and economies of many SSA countries, especially if regulatory mechanisms are deployed to govern their protection and utilisation

To reduce maternal deaths and pregnancy-related complications, TMs used during pregnancy need to be better known and thoroughly researched regarding their safety. Research into the TMs used will aid women in receiving adequate treatment, to identify potentially unsafe use, and also preserve valuable information about medicinal in the future as well as declare the different types of TMs they would have used in their health facilities to aid complementarity and better management of the pregnancies9,30 Therefore, this review explored TM utilisation during pregnancy in SSA. The following 3 specific objectives have guided this enquiry: 1) Determining the proportion of pregnant women utilising TMs in SSA 2) Identifying the different types of TM used during antenatal care and reasons for Use in SSA 3) Identifying challenges that are faced by women who use TM in antenatal care.
Methodology
Inclusion Criteria
Studies were included if they reported the Use of TMs by SSA women for reasons related to preparation for pregnancy, promoting fertility, treating pregnancy-related symptoms, maintenance of general wellbeing during pregnancy, inducing or assisting labour. Studies were also included if they described the views, attitudes and beliefs of women regarding TM utilisation. All studies published in English (up to 17 November 2021) in reputable peer-reviewed journals, and available open access were targeted.
Exclusion Criteria
The study excluded all published literature sources that addressed TM related issues but did not focus on SSA. Furthermore, literature sources that focused on women’s Use of TM for general purposes and other conditions other than pregnancy were excluded.
Keywords for Literature Search
The keywords for the literature search engines included traditional medicine utilisation, SSA pregnant women.
Search Strategy
The keywords (Traditional medicine; pregnant women; herbal medicines; phytotherapy, Sub-Saharan Africa complementary and alternative medicines) were used to search for literature on Google Scholar, PubMed, Cochrane, HINARI and the WHO website. The literature search was done up to 17 November 2021.
Methods of Review
We reviewed independently titles and abstracts of articles and reports that were relevant and qualified to be included in this study. Disagreements were resolved through dialogue between we and reaching an agreement based on issues arising and exchanged. The 2 authors reviewed full texts of these articles and reports that met the inclusion criteria, and findings were discussed, and an agreement was reached.
Data Extraction and Synthesis
We developed a data collection form as guided by the objectives to facilitate uniformity in data collection (by the authors). The we reviewed articles and reports and collected data. Discrepancies observed on collected data by the authors were resolved through dialogue and reaching a consensus. Findings from the articles and reports were then coded and thematically analysed in line with the specific objectives.
Quality Assessment
For this review, the quality was assessed using a purposive rating tool adapted from the AMSTAR checklist 31 This scale is a freely accessible, validated tool for evaluating the methodological quality of reviewed documents. AMSTAR items contain several aspects; therefore, only components relevant to the research scope were used 31 The primary purpose of this rating tool was to evaluate the scientific quality/rigour of systematic reviews in TM use, and question 1–6 was used in the checklist 31
Results
A total of 1770 literature sources were obtained from electronic databases. After excluding 1672 duplicates and irrelevant sources, 98 sources had their titles and abstracts screened. After screening, 47 articles were found not to address the objectives of this review, and some were not available open access, and some failed the quality test (16) and were excluded leaving 51 that underwent full manuscript review. Three of the 51 were excluded as they gave a general perspective of TM use, and the remaining 48 were eligible and included in this systematic review. The summary of this inclusion/exclusion process is shown in Figure 1.

Proportion of Pregnant Women Utilising Traditional medicines in Sub-Saharan African
It is estimated that TM utilisation by women in SSA is estimated to be between 30 and 70% 4 Subsidising influences to increase the Use of TMs include culture and beliefs, poverty, long distance to health facilities, cost of modern medicines and acceptability of TM 32 Results from different studies indicate that prevalence varies depending on the country, and in SSA, it ranges from 12 to 93% among pregnant women, as influenced by different contextual settings in different countries. These findings are presented in Table 1.

Traditional medicines Used During pregnancy Among Sub-saharan African Women
A study conducted in South Africa cited ten species as frequently used for the treatment of common pregnancy-related problems such as oedema, indigestion, constipation, infection, high blood pressure and post-partum healing 33 Also, a study conducted in Zimbabwe identified 8 species of herbal medicines, with many being used to quicken labour 34 Table 2 shows some traditional remedies used in Sub-Saharan Africa during pregnancy with Asparagus Africanus used in South Africa and Zimbabwe.

Discussion
The review indicated that the prevalence of TM utilisation during pregnancy is predominant and varies across different countries. Increasing prevalence is no longer debatable even though there is a previous misconception regarding herbal medicinal products as safe and raw consumption from their natural state. In several countries, herbal medicines and related products are introduced without any mandatory safety or toxicological evaluation, which makes patients have access to them 35 Studies conducted in Australia are within the range obtained by our review, with between 48% and 69% prevalence36,37 In Ghana, TM use in pregnancy is triggered by low education levels and long distances to the hospital and unpleasant interactions with health service providers in the modernised health facilities 4 The promotion of TM in society and the media is another contributing factor that increases prevalence in some Sub-Saharan countries 32 It should also be noted that TM utilisation is higher in countries that have poorly financed health systems that usually change significant amounts of monies from users, the majority of who would be poor and could barely afford the fees charged38,39
As our study indicated that prevalence varies, literature shows that increasing utilisation of traditional remedies is also caused by unease or discomfort about discussing their medical problems and fear of confidentiality in handling their health information 40 Influence of religion and a greater level of spiritual consciousness, many individuals tend to be increasingly disposed to accepting the therapeutic value based on faith or intuition rather than scientific reasoning 41 Numerous studies also indicate that traditional remedies usage is mostly recommended by traditional birth attendants, close relatives, and on rare occasions by health care providers. It is revealed that family members who advise on using herbal medicines may not have sufficient knowledge of the herbs and remedies 42
Confidence in herbal remedies is relatively high among primitive individuals, mainly those based in rural populations. It is associated with a lack of access to public healthcare, social and cultural values, perceived efficacy, beliefs about safety and general ease of access 43 However, though women have access to public healthcare facilities in urban areas, women still rely on alternative or traditional systems of care 43 In public health care, herbal medicines have been proved to impact the health-seeking behaviours of patients, prescribed drug use and health outcomes 44 Some women use herbal medicines secretively as compared to modern medications 44
Even though our review showed that Meconium-Stained Liquor (MLS) is a result of traditional remedies used but other scholars highlight that it can occur without any form of medications or if there is no foetal distress during pregnancies33,45, the review indicated Isihlambelo, which is commonly used in South Africa among Zulu that causes uterine contraction thereby quickening labour 46 Although some studies reveal adverse effects of traditional herbs, some highlights their benefit as some herbs have sugar components that can be the source of nutrition and energy to a pregnant woman, although others are antioxidants with health benefits, thereby boosting the immune system, preventing respiratory diseases and preventing birth defects47–49
Preeclampsia, nausea and vomiting have been noted in the review as complications among pregnant women who utilise traditional remedies. Other studies acknowledge that preeclampsia, vomiting and nausea are common during pregnancy and suggest modern ways of controlling such as regular intake of at least 1500 mg of calcium each day during pregnancy could significantly reduce the risk of preeclampsia and substantially lower blood pressure 50 It is also reported that hyperemesis gravidarum, Zingiber officinale (ginger) root is beneficial both in milder nausea and hyperemesis 51
Results revealed that several factors had triggered utilisation of TMs, and studies in different geographic setups indicate factors such as the belief that herbal products are superior to manufactured products 52 Furthermore, discontent with the results from approved modern medicines and the belief that herbal medicines might be helpful in the treatment of certain diseases where conventional therapies and medicines have proven to be ineffective. Some TMs are locally available and easily accessible in SSA. Accessibility and availability of TM in SSA are well documented and highlighted in the literature as an alternative remedy that promotes self-medication 52
The review also indicated that there are no formal regulations of this herbal medicines 29 The absence of these regulations is contrary to the European Union (EU), which implemented a directive to harmonise the management of traditional herbal medicinal products across the EU and establish a simplified licensing system to help the public make informed choices about the use of herbal products 53 It is expected that stakeholders producing herbal products have a product license or become registered as a traditional herbal medicinal dealer/distributor53,54 In developing countries, there is a lack of capacity to regulate manufacturing practices and enforce quality standards 50 These herbal products have been consistently made available to consumers without prescription, and in most cases, the potential hazards in a low-grade product are hardly recognised 52
This review indicated that different TM was used to ensure the sound development of the foetus, quicken labour, prevent or cure malaria and prevent miscarriages. Published sources from countries such as Ivory Coast, Nigeria, Zambia, Uganda, Tanzania, Benin and Gabon reveal extensive use of different types of TMs among women 55 In a study conducted in Uganda, Ivory Coast, Tanzania, Benin, Gabon study among women, 75, 75, 23, 248, 189 plant species were identified for use during pregnancy and labour, respectively 55
Limitations of the Study
We did not find some Latin Names for some of the TMs that different women in the literature used, and some literature just presented. It should also be noted that the environment we live in is dynamic, and new information comes through. Therefore, some studies may have been missed in this study. It should also be noted that this study was not funded; therefore, the literature search was limited to only those available sources open access from the databases.
Conclusion
There is proof that TM is widely used during pregnancy among Sub-Saharan African women. However, there is a gap as most studies focus on presenting general TMs utilisation patterns without paying particular attention to its application to maternal health-related issues and the complications associated with its use thereof. There is a need to determine the chemical components and mode of action of these herbs as some are beneficial, whilst others could be harmful, leading to severe maternal complications. Stakeholders within the domain of maternal health systems should design standardised guidelines and policies that might regulate the utilisation of traditional remedies by pregnant women.
