Osborne A, Bangura C. Predictors of insecticide-treated bed nets use among pregnant women in Sierra Leone: evidence from the 2019 Sierra Leone Demographic Health Survey. Malar J 2024; 23:193. [PMID: 38898414 PMCID: PMC11188154 DOI: 10.1186/s12936-024-05018-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Accepted: 06/16/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Malaria remains a significant public health threat in Sierra Leone, particularly for pregnant women and their unborn children. Infection during pregnancy can lead to severe consequences, including maternal anaemia, low birth weight, premature birth, and even death. Therefore, preventing malaria during pregnancy is crucial for improving maternal and child health outcomes. This study investigated the predictors of insecticide-treated bed net (ITN) use among pregnant women in Sierra Leone. METHODS The study analysed the 2019 Sierra Leone Demographic and Health Survey data (SLDHS). The study comprised a total of 900 pregnant women aged 15-49 years, representing the nationally representative sample. A multivariable binary regression analysis was used to explore the predictors of ITN use. The regression results were presented using an adjusted odds ratio (AOR) with 95% confidence intervals (CI). RESULTS The study found that the prevalence of ITN use among pregnant women was 64.2 [60.4, 67.9] in Sierra Leone. Pregnant women who were married [aOR = 2.02, 95% CI 1.32, 3.07] had higher odds of bed net use than those who were unmarried. Pregnant women with five or more children [aOR = 1.69, 95% CI 1.01, 2.84] had higher odds of mosquito bed net use than those with four and below children. Pregnant women living in the Northern, Northwestern, Southern and Western regions all had lower odds of bed net use than those in the Eastern region, with the lowest odds among those living in the western region [aOR = 0.19, 95% CI 0.09, 0.40]. Pregnant women who were Muslims [aOR = 0.63, 95% CI 0.41, 0.95] had lower odds of mosquito bed net use than Christians. Pregnant women with female household heads [aOR = 0.65, 95% CI 0.44, 0.95] had lower odds of mosquito bed net use than those with male household heads. CONCLUSION ITN use among pregnant women in Sierra Leone remains suboptimal. Marital status, parity, sex of household head, region and religion were associated with bed net use. The government and policymakers in Sierra Leone should integrate ITN education and distribution into prenatal care services, emphasizing the benefits for both mother and baby-partnering with healthcare providers to raise awareness and encourage consistent use. Involve local leaders, religious figures, and mothers' groups to promote the benefits of ITN during pregnancy. Educate husbands and partners on the importance of ITN use during pregnancy and encourage their support in its consistent use.

[PMID: 38931045 PMCID: PMC11207860 DOI: 10.3390/plants13121613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/29/2024] [Accepted: 06/05/2024] [Indexed: 06/28/2024]
Abstract
While Moringa oleifera Lam. is gaining importance in Africa, especially sub-Saharan Africa, it is unclear whether research is following the quick pace of its development on the continent. Therefore, this article analyzes the landscape of research dealing with moringa in Africa. This systematic review draws upon 299 eligible articles identified through a search carried out on the Web of Science in April 2023. Research on M. oleifera is rather recent in Africa but interest is increasing among scholars. While the research field is multidisciplinary and cross-sectoral, the literature seems to focus on biological and environmental sciences. Moreover, research is performed mainly in South Africa, Nigeria, Egypt, and Ghana. The analysis suggests a significant potential contribution of moringa to food security and nutrition, climate change mitigation/adaptation, farming systems resilience, and livelihoods. Its versatility and diverse applications and uses make moringa particularly interesting for developing countries, such as African ones. However, this review also underscores some factors hindering its development. Therefore, there is a need to strengthen research on moringa to unlock its potential in Africa. Investments in research, innovation, and development can help address the many challenges that Africa faces and contribute to the transition towards sustainable and resilient food systems.

In-vitro antimalarial activity of methanolic leaf- and stem-derived extracts from four Annonaceae plants. BMC Res Notes 2023; 16:381. [PMID: 38135870 PMCID: PMC10740295 DOI: 10.1186/s13104-023-06664-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 12/11/2023] [Indexed: 12/24/2023] Open
Abstract
OBJECTIVE Plants in the Annonaceae family are known for having abundant biologically active secondary metabolites. They have been used in alternative drugs for various diseases in several countries, for instance, the bark of Cananga odorata (Lam.) Hook and Thomson is used for Ophthalmic inflammation and wound healing in Malaysia. Extracts from the leaves and stems of four Annonaceae plants, namely Uvaria longipes (Craib) L.L.Zhou, Y.C.F.Su & R.M.K.Saunders, Dasymaschalon sp., Artabotrys burmanicus A.DC, and Marsypopetalum modestum (Pierre) B.Xue & R.M.K.Saunders were investigated for growth inhibitory activity against blood-stage Plasmodium falciparum growth in vitro and for non-specific cytotoxicity against normal peripheral blood mononuclear cells (PBMCs). Antimalarial activity was assessed by invasion inhibition assay and the percentage of infected red blood cells on blood smears were determined. Cytotoxicity was tested by culturing PBMCs with the extracts, and viabilities were determined by Annexin V/propidium iodide staining. RESULTS A. burmanicus stem extract and M. modestum leaf extract were capable of inhibiting growth of P. falciparum when used at 200 µg/mL compared to chloroquine. The extracts at effective concentrations, did not affect the viability of PBMCs. These results support further need for characterization of active compounds from specific Annonaceae plants in order to exploit their components for potential malaria treatment.

Abstract
Child survival and wellbeing remain a global health challenge despite vast development within the area and a significant decline in mortality rates of children under five years of age. This study investigates the perceived causes of ill health and childhood mortality in the context of five villages located in the Tonkolili district of Sierra Leone. Mixed method methodology was applied in this study consisting of both quantitative and qualitative data contribution. The quantitative part consisted of a household survey on child health, where 341 households, equivalent to 50.6% of the total number of households in the five villages, participated with a response rate of 100%. The qualitative part consisted of six semi structured interviews-one with a health care worker and five with mothers from each village. The main perceived reason for child morbidity was inadequate care of children related to personal hygiene of the child, hygiene and safety in the environment, in-sufficient nutrition, inadequate supervision and poor healthcare seeking behavior. Additionally, reasons given for disease included supernatural forces such as witchcraft. In relation to the survey, the perceived causes of child mortality for ill children in the villages were mainly malaria (33.6%), diarrhea (11.6%), pneumonia (8.6%), and unknown (26%). The observed symptoms of illness among children were fever (43.7%), cough and difficulty breathing (10.7%), frequent watery stool (10.3%) and no symptoms (20.3%). The perception of ill health in children was mainly associated with the parent's ability to cater for the child's physical needs, but also associated with external factors such as witchcraft and "God's will". In addition, biomedical causes for disease and supernatural causes for disease were seen to coexist.

Abstract
BACKGROUND Considerable number of patients, including Ebola survivors, in Sierra Leone, are using traditional and complementary medicine (T&CM). Healthcare providers' (HCPs) views about T&CM is crucial in addressing the increased need for T&CM among patients. However, healthcare providers' views about T&CM in Sierra Leone is unknown. Our study explores healthcare providers' knowledge of and perception towards T&CM and how that influence their personal and professional T&CM use, communication with Ebola survivors about T&CM as well as its integration into the healthcare system in Sierra Leone. METHODS We employed a qualitative exploratory study design using semi-structured interviews to collect data from 15 conveniently sampled HCPs in all four geographical regions of Sierra Leone. We analysed our data using thematic network analysis framework. RESULTS Healthcare providers perceived their knowledge about T&CM to be low and considered T&CM to be less effective and less safe than conventional medicine as well as not evidence-based. HCPs perception of T&CM as non-scientific and their lack of knowledge of T&CM were the key barriers to HCPs' self-use and recommendation as well as their lack of detailed discussion about T&CM with Ebola survivors. HCPs are open to T&CM integration into mainstream healthcare in Sierra Leone although at their terms. However, they believe that T&CM integration could be enhanced by effective professional regulation of T&CM practice, and by improving T&CM evidenced-based knowledge through education, training and research. CONCLUSION Changing HCPs' negative perception of and increasing their knowledge about T&CM is critical to promoting effective communication with Ebola survivors regarding T&CM and its integration into the healthcare system in Sierra Leone. Strategies such as educational interventions for HCPs, conducting rigorous T&CM research, proper education and training of T&CM practitioners and effective professional regulation of T&CM practice could help in that direction.

Abstract
In the last few decades, Moringa oleifera, a multipurpose medicinal plant (MMP) has received increased research attention and commercial interest for its nutritional, therapeutic and pharmacological properties. Rigorous approaches including biological assays, animal and clinical trials are required towards safe usage as herbal therapy. We conducted a systematic review of the known pharmacological activities, toxicity, and safety of M. oleifera, usually used locally in the treatment and prevention of myriads of illnesses. Five major bibliographic databases (SCOPUS, Web of Science, Science Direct, PubMed, and Mendeley) were searched for studies reported on pharmacological activities, toxicity, and safety assessment of M. oleifera in the last 29 years (1990 – 2019). Studies on animals and humans involving aqueous leaf extracts and different preparations from M. oleifera seed and bark were also considered. All articles retained, and data collected were evaluated based on the period of the article, country where such studies were conducted and the document type. Our search results identified and analyzed 165 articles while 63 studies were eventually retained. Diverse pharmacological activities including neuroprotective, antimicrobial, antiasthmatic, anti-malaria, cardioprotective, antidiabetic, antiobesity, hepatoprotective and cytotoxic effects, amongst others, were recorded. Toxicity studies in animal models and few human studies showed that M. oleifera is safe with no adverse effect reported. The importance of the plant is highlighted in the search for new bioactive compounds to explore its therapeutic potentials towards drug discovery and development in the pharmaceutical and allied industries.

Abstract
BACKGROUND Malaria is a worldwide problem that affects millions of people yearly. In rural areas where anti-malarial drugs are not easily accessible, many people use herbal treatments, such as Moringa oleifera, to treat a variety of diseases and ailments including malaria. While Moringa is reported to possess potent and curative anti-malarial properties, previous studies have mostly been restricted to assessment of parasitaemia. In this study, the effect of Moringa on malaria immunity in a murine model was investigated. METHODS Using a high dose (60 mg/mouse) for a short time (7 days) or low dose Moringa (30 mg/mouse) for a longer time (3 weeks), cytokine production, and Tbet expression by effector CD4+ T cells (Teff) were determined. Mice were also treated with Moringa after infection (curatively) or before infection (prophylactically) to determine the effect of the plant extract on parasitaemia and immunity. Given that Moringa also possess many nutritional benefits, the contribution of Moringa on malnourished malaria infected mice was determined. Malnutrition was induced by limiting access to food to only 4 h a day for 4 weeks, while control mice had unlimited access to mouse laboratory chow. All data was collected by flow cytometry and analysed using one-Way ANOVA or two tailed Student's t test. RESULTS Moringa-treated mice had increased numbers of effector CD4+ T cells accompanied by an increase in Tbet expression compared to control untreated mice. Mice that were treated with Moringa curatively also exhibited increased effector CD4+ T cell numbers, IFN-gamma and TNF secretion. Interestingly, the mice that were treated prophylactically had significantly higher Tbet expression. In the absence of adaptive immunity, high parasitaemia was observed in the RAG1 knockout mice. The food limited mice (malnourished) had reduced numbers of CD4+ T cells, TNF proportions, and significantly greater Tbet expression compared to the control group. Supplementation with Moringa in the limited group slightly restored CD4+ T cell activation, IL-2, and IL-10 production. CONCLUSIONS Taken together, these data suggest that Moringa treatment leads to increased CD4+ T cell activation, Th1 differentiation and production of pro-inflammatory cytokines after malaria infection. Thus, Moringa may be immunologically useful in the treatment of malaria and malnutrition. Further investigations are required to identify the active components in Moringa.

BMC Public Health 2020; 20:182. [PMID: 32020858 PMCID: PMC7001224 DOI: 10.1186/s12889-020-8279-7] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 01/27/2020] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND We examined the magnitude and correlates of Ebola virus disease (EVD)-related stigma among EVD survivors in Sierra Leone since their return to their communities. In addition, we determined whether EVD-related stigma is a predictor of informal health care use among EVD survivors. METHODS We conducted a cross-sectional study among 358 EVD survivors in five districts across all four geographic regions (Western Area, Northern Province, Eastern Province and Southern Province) of Sierra Leone. Ebola-related stigma was measured by adapting the validated HIV related stigma for people living with HIV/AIDS instrument. We also measured traditional and complementary medicine (T&CM) use (as a measure of informal healthcare use). Data were analysed using descriptive statistics and regression analysis. RESULTS EVD survivors report higher levels of internalised stigma (0.92 ± 0.77) compared to total enacted stigma (0.71 ± 0.61). Social isolation (0.96 ± 0.88) was the highest reported enacted stigma subscale. Ebola survivors who identified as Christians [AOR = 2.51, 95%CI: 1.15-5.49, p = 0.021], who perceived their health to be fair/poor [AOR = 2.58, 95%CI: 1.39-4.77. p = 0.003] and who reside in the northern region of Sierra Leone [AOR = 2.80, 95%CI: 1.29-6.07, p = 0.009] were more likely to experience internalised stigma. Verbal abuse [AOR = 1.95, 95%CI: 1.09-3.49, p = 0.025] and healthcare neglect [AOR = 2.35, 95%CI: 1.37-4.02, p = 0.002] were independent predictors of T&CM use among EVD survivors. CONCLUSION Our findings suggest EVD-related stigma (internalised and enacted) is prevalent among EVD survivors since their return to their communities. Religiosity, perceived health status and region were identified as independent predictors of internalised stigma. Verbal abuse and healthcare neglect predict informal healthcare use. EVD survivor-centred and community-driven anti-stigma programs are needed to promote EVD survivors' recovery and community re-integration.

Abstract
Background It is well established that Ebola Survivors experience a myriad of physical and psychological sequelae. However, little is known about how they seek care to address their health needs. Our study determines the current healthcare seeking behaviour among Ebola survivors and determines the prevalence, pattern of use and correlates of traditional and complementary medicine (T&CM) use among Ebola survivors in Sierra Leone. Methods We conducted a nationwide questionnaire survey among a cross-sectional sample of Ebola Survivors in Sierra Leone between January and August 2018. We employed descriptive statistics, chi-square test, Fisher exact two-tailed test and backward stepwise binary regression analysis for data analysis. A p-value less than 0.05 was considered statistically significant. Results Ebola Survivors who participated in our study (n = 358), visited a healthcare provider (n = 308, 86.0%), self-medicated with conventional medicines (n = 255, 71.2%) and visited a private pharmacy outlet (n = 141, 39.4%). Survivors also self-medicated with T&CM products (n = 107, 29.9%), concurrently self-medicated with conventional and T&CM products (n = 62, 17.3%), and visited a T&CM practitioner (n = 41, 11.5%). Almost half of (n = 163, 45.5%) Ebola survivors reported using T&CM treatments for post ebola related symptoms and non-Ebola related symptoms since their discharge from an Ebola treatment centre. Ebola survivors who considered their health to be fair or poor (AOR = 4.08; 95%CI: 2.22–7.50; p<0.01), presented with arthralgia (AOR = 2.52; 95%CI: 1.11–5.69, p = 0.026) and were discharged three years or less (AOR = 3.14; 95%CI: 1.13–8.73, p = 0.028) were more likely to use T&CM. Family (n = 101,62.0%) and friends (n = 38,23.3%) were the common sources of T&CM information. Abdominal pain (n = 49, 30.1%) followed by joint pain (n = 46, 28.2%) and back pain (n = 43, 26.4%) were the most cited post–Ebola indications for T&CM use. More than three-quarters of T&CM users (n = 135, 82.8%) failed to disclose their use of T&CM to their healthcare providers. Conclusion Ebola survivors in Sierra Leone employ a myriad of healthcare options including T&CM in addressing their healthcare needs. Researchers, health policy makers and healthcare providers should be aware of the substantial role of T&CM in the health seeking of survivors, and this topic that should be factored into future research, policy formulation and implementation as well as routine practice regarding Ebola survivors.

[PMID: 31323758 PMCID: PMC6681324 DOI: 10.3390/medicina55070387] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 06/27/2019] [Accepted: 07/12/2019] [Indexed: 12/29/2022]
Abstract
Background and objectives: In addition to conventional healthcare, Ebola survivors are known to seek traditional and complementary healthcare (T&CM) options to meet their healthcare needs. However, little is known about the general beliefs of Ebola survivors regarding T&CM and the impact of these beliefs in influencing their decisions around T&CM use. This study examines Ebola survivors' attitudes towards T&CM use in Sierra Leone. Materials and Methods: We conducted a nationwide quantitative cross-sectional study of 358 Ebola survivors in Sierra Leone between January and August 2018. We used descriptive analysis, chi-square tests and backward stepwise binary logistic regression for data analysis. Results: Close to half of the survivors (n = 163, 45.5%) had used T&CM since their discharge from an Ebola treatment centre. Survivors who viewed T&CM as boosting their immune system/resistance were 3.89 times (95%CI: 1.57-9.63, p = 0.003) more likely to use T&CM than those who did not view T&CM as boosting their immune system/resistance. Additionally, survivors who viewed T&CM as having fewer side effects than conventional medicine were more likely to use T&CM [OR = 5.03 (95%CI: 1.92-13.19, p = 0.001)]. Ebola survivors were more influenced to use T&CM based on their personal experience of the effectiveness of T&CM than by clinical evidence [OR = 13.72 (95%CI: 6.10-30.84, P < 0.001)]. Ebola survivors who perceived T&CM as providing them with more control than conventional medicine over their health/body were more likely to use T&CM [OR = 4.15 (95%CI: 1.74-9.89, p = 0.001)] as opposed to those who did not perceive T&CM in this way. Conclusions: Considering the widespread use of T&CM, an understanding of Ebola survivors' attitudes/beliefs towards T&CM is useful to healthcare providers and policymakers with regard to public education and practitioner-survivors communication, T&CM regulation and research in Sierra Leone. Ebola survivors appear to turn to T&CM not only for treatment, but also to fill gaps in conventional health care services.

Abstract
A method for detecting the organophosphorus pesticides residue and aflatoxins in China herbal tea has been developed by UPLC-MS/MS coupled with vortex-assisted dispersive liquid-liquid microextraction (DLLME). The extraction conditions for vortex-assisted DLLME extraction were optimized using single-factor experiments and response surface design. The optimum conditions for the experiment were the pH 5.1, 347 µL of chloroform (extraction solvent) and 1614 µL of acetonitrile (dispersive solvent). Under the optimum conditions, the targets were good linearity in the range of 0.1 µg/L⁻25 µg/L and the correlation coefficient above 0.9998. The mean recoveries of all analytes were in the ranged from 70.06%⁻115.65% with RSDs below 8.54%. The detection limits were in the range of 0.001 µg/L⁻0.01µg/L. The proposed method is a fast and effective sample preparation with good enrichment and extraction efficiency, which can simultaneously detect pesticides and aflatoxins in China herbal tea.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 19:66. [PMID: 30876454 PMCID: PMC6420723 DOI: 10.1186/s12906-019-2479-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Accepted: 03/11/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND The use of medications, including herbal medicines during breastfeeding is always a concern among women. Currently, there is no published evidence on whether Sierra Leonean women use herbal medicine during breastfeeding. This study investigates the prevalence, correlates and pattern of herbal medicine use during breastfeeding. METHODOLOGY We conducted a cross-sectional study among 378 current breastfeeding mothers visiting public healthcare facilities within the Western area of Sierra Leone. Descriptive statistics and logistic regression analysis were used for data analysis. RESULTS Over a third of mothers (n = 140, 37.0%) used herbal medicine during breastfeeding. However, very few herbal medicine users (2.1%, n = 3) used herbal medicine to augment breastfeeding. Dietary changes were the most common method used to increase breast milk supply (93.9%, n = 355) with cassava leaves sauce and tubers being the most common dietary addition. Mothers with children more than six months old were more likely to use herbal medicine than mothers with younger children (OR:1.8; CI:1.13-2.85,p = 0.013). Among herbal medicine users, only 11.4% (n = 16) disclosed their herbal medicine use to their conventional healthcare providers. CONCLUSION The use of herbal medicine among breastfeeding mothers attending public health facilities in the Western area of Sierra Leone is common. Whilst this use is not usually specific to increasing breast milk supply, our study indicates that herbal medicines may be used to 'cleanse' initial breast milk.

Abstract
Background The WHO estimates that a considerable number of people in Sub-Saharan Africa (SSA) rely on traditional, complementary and alternative medicine (TCAM) to meet their primary healthcare needs, yet there remains a dearth of research evidence on the overall picture of TCAM utilisation in the region. Methods We conducted a literature search of original articles examining TCAM use in SSA between 1 January 2006 and 28 February 2017, employing Medline, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Scopus, ProQuest, PubMed, Embase and African Journals Online databases. A critical appraisal of relevant articles reporting a quantitative or mixed-method design was undertaken. Results Despite the heterogeneity and general low quality of the identified literature, the review highlights a relatively high use of TCAM alone or in combination with orthodox medicine, in both general population and in specific health conditions in SSA. TCAM users compared with non-TCAM users are more likely to be of low socioeconomic and educational status, while there were inconsistencies in age, sex, spatial location and religious affiliation between TCAM users and non-TCAM users. Most TCAM users (55.8%–100%) in SSA fail to disclose TCAM use to their healthcare providers, with the main reasons for non-disclosure being fear of receiving improper care, healthcare providers’ negative attitude and a lack of enquiry about TCAM use from healthcare providers. Conclusion TCAM use in SSA is significant, although most studies emerge from a few countries. Factors associated with TCAM use in SSA are similar to those observed in other regions, but further research may be required to further elucidate challenges and opportunities related to TCAM use specific to SSA.

JOURNAL OF ETHNOPHARMACOLOGY 2018; 222:217-228. [PMID: 29730132 DOI: 10.1016/j.jep.2018.04.026] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2017] [Revised: 04/18/2018] [Accepted: 04/18/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbal teas have long been consumed by Chinese people for preventive and/or therapeutic healthcare. Although herbal teas are widely consumed by many cultural groups in different regions of China, no thorough review has been undertaken to assess the diversity of the country's herbal tea usage. This literature review, complemented by a quantitative survey in an important tea market in Kunming, begins to fill this knowledge gap. AIMS OF THE STUDY The study aims to summarize the current knowledge of plant species used as herbal teas by different cultural groups in different regions of China, with a focus on the teas' perceived traditional healthcare functions, related phytochemical/pharmaceutical research, and safety issues. MATERIALS AND METHODS The study involved a comprehensive literature review and a market survey. The literature review was based on published ethnobotanical studies of herbal teas in China. We searched the Web of Science™, ELSEVIER, the China National Knowledge Infrastructure (CNKI) and the China Science and Technology Journal Database to locate relevant studies (including journal articles, Masters/PhD dissertations and books) that were published before March 2017. A species list was compiled based on the review and supplemented with information retrieved from the Scifinder database (https://scifinder.cas.org) and the Chinese Pharmacopoeia (2010). A Use Value Index was employed for ranking the most cited species. Based on the 29 most cited species, we discussed the current research status in relation to healthcare benefits and safety concerns of herbal teas in China. To better understand the current status of the herbal tea market in China, we also surveyed 136 tea vendors at the Xiongda Tea Market in Kunming. Information gathered from the survey included the species sold, the sale prices and the form of the herbal tea product. RESULTS The literature identified 759 plant species used as herbal tea in China and the market survey identified an additional 23 species. Most of the species used were from the Leguminosae, Compositae and Lamiaceae families. Twenty two provinces and fourteen ethnic minority groups have records on the consumption of herbal teas. Southern China uses up to 82% of the total species, and 211 out of 759 species are used by minority groups. Thirty categories of traditional healthcare functions are linked with herbal teas, with clearing away heat, relieving toxicity and suppressing cough being the most important functions. There is phytochemical/pharmaceutical evidence to support the claimed healthcare benefits of some Chinese herbal teas. Although Chinese herbal teas are generally safe to consume, overdoses of some herbal teas and some unapproved mixtures of species may cause health risks. Based on our market survey, the prices of most herbal teas range between 100 and 200 RMB (US$15-30) per kg. CONCLUSIONS A rich array of herbal tea species with various traditional healthcare functions have long been used in China, and as such there is a huge market potential for Chinese herbal teas. More pharmaceutical/phytochemical research is needed to assess a wide range of perceived healthcare benefits of Chinese herbal teas. Our research highlights the need to study herbal teas through an ethnopharmacological perspective and by employing a holistic approach, which requires greater consideration of traditional knowledge in the pharmacological research design. Product safety and sustainability issues should also be considered, so the traditional applications of herbal teas can be transformed to efficient health boosting functional products.

Prevalence and Correlates of Herbal Medicine Use among Women Seeking Care for Infertility in Freetown, Sierra Leone. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:9493807. [PMID: 29849738 PMCID: PMC5937420 DOI: 10.1155/2018/9493807] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/24/2017] [Revised: 02/06/2018] [Accepted: 02/18/2018] [Indexed: 12/16/2022]
Abstract
In resource-poor countries where access to infertility care is limited, women may turn to traditional medicine to achieve motherhood. It is unknown whether Sierra Leonean women with such condition use herbal medicine. This study investigates the prevalence and factors associated with herbal medicine use among women seeking care for infertility. This was a questionnaire-based cross-sectional study conducted among women seeking care for infertility at various clinics within Freetown, Sierra Leone. Data analysis included Chi-square tests and logistic regression. Out of the 167 women that participated, 36.5% used herbal medicine for infertility treatment. Women with no formal (AOR 4.03, CL: 1.38-11.76, p = 0.011), primary education (AOR: 6.23, CL: 2.02-19.23, p = 0.001) and those that visited a traditional medicine practitioner (AOR: 20.05, CL: 2.10-192.28, p = 0.009) as well as women suffering from other reproductive health problems (AOR: 2.57, CL: 1.13-5.83, p = 0.024) were more likely to use herbal medicines. Friends and family (n = 57, 96.7%) were the main influencers of herbal medicine use. Only (n = 12) 19.7% of users disclosed their status to their healthcare provider. Over half (n = 32, 52.5%) could not remember the name of the herb they used. Luffa acutangula (n = 29, 100%) was the herbal medicinal plant users could recall. Herbal medicine use among women seeking care for infertility in Freetown is common. Healthcare providers should be aware of the potential dyadic use of herbal and allopathic medicines by their patients and be knowledgeable about commonly used herbal remedies as well as being proactive in communicating the potential risks and benefits associated with their use.

Abstract
ETHNOPHARMACOALOGICAL RELEVANCE The genus Nauclea in Africa comprises seven species. Among them, N. latifolia, N. diderrichii and N. pobeguinii are widely used by the local population in traditional remedies. Preparation from various parts of plants (e.g. roots, bark, leaves) are indicated by traditional healers for a wide range of diseases including malaria, pain, digestive ailments or metabolic diseases. MATERIALS AND METHODS A literature search was conducted on African species of the genus Nauclea using scientific databases such as Google Scholar, Pubmed or SciFinder. Every document of ethnopharmacological, phytochemical or pharmacological relevance and written in English or French were analyzed. RESULTS AND DISCUSSION The Nauclea genus is used as ethnomedicine all along sub-Saharan Africa. Several local populations consider Nauclea species as a major source of remedies for malaria. In this regard, two improved traditional medicines are currently under development using extracts from N. latifolia and N. pobeguinii. Concerning the chemical composition of the Nauclea genus, indoloquinolizidines alkaloids could be considered as the major class of compounds as they are reported in every analyzed Nauclea species, with numerous structures identified. Based on traditional indications a considerable amount of pharmacological studies were conducted to ensure activity and attempt to link them to the presence of particular compounds in plant extracts. CONCLUSION Many experimental studies using plant extracts of the African species of the genus Nauclea validate traditional indications (e.g. malaria and pain). However, bioactive compounds are rarely identified and therefore, there is a clear need for further evaluations as well as for toxicity experiments. The sustainability of these plants, especially of N. diderrichii, a threatened species, should be kept in mind to adapt local uses and preparation modes of traditional remedies.

Abstract
OBJECTIVE This study aimed to determine the prevalence, determinants and pattern of herbal medicine use among hypertensive patients in Freetown. METHODS AND MATERIALS We conducted a cross-sectional study among hypertensive patients attending public and private health facilities in Freetown, Sierra Leone between August and October 2016. We analyzed the data using SPSS version 24. We used Chi-square, Fisher exact two-tailed test and regression analysis for data analysis. A p-value less than 0.05 was considered statistically significant. RESULTS Out of 260 study participants, over half (n = 148, 56.9%) reported using herbal medicine for the treatment of hypertension alone or together with comorbid condition(s). The most commonly used herbal medicine among users were honey (n = 89, 33.3%), moringa (n = 80, 30.0%) and garlic (n = 73, 27.3%). No significant difference existed between users and non-users of herbal medicine with regards to socio-demographic and health-related factors. The majority (n = 241, 92.7%) of respondents considered herbal medicine beneficial if it was recommended by a healthcare provider yet 85.1% (n = 126) did not disclose their herbal medicine use to their health care provider. CONCLUSION There is a high use of herbal medicines among hypertensive patients in Freetown, Sierra Leone. It is essential for healthcare providers to take heed of the findings of this study and routinely ask their patients about their herbal medicine use status. Such practice will provide the opportunity to discuss the benefits and risks of herbal medicine use with the aim of maximizing patient desired therapeutic outcomes.

[PMID: 29254852 DOI: 10.1016/j.wombi.2017.12.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2017] [Revised: 11/06/2017] [Accepted: 12/04/2017] [Indexed: 12/30/2022]
Abstract
BACKGROUND The influence of complementary therapies on maternal health has attracted the attention of policy makers, health professionals and researchers globally especially in developing countries. However, there is lack of evidence on whether Sierra Leonean women use herbal medicine during pregnancy which limit the chance of providing better maternity care. AIM This study was conducted to determine the prevalence and pattern of herbal medicines use among pregnant women attending an antenatal clinic at a tertiary maternal hospital in Sierra Leone. METHODS A cross-sectional study was conducted among pregnant women (n=134) who were at least 18 years of age and who have had at least one previous pregnancy, using face to face interview. Descriptive statistics, univariate and multivariate logistic regression analysis were used for data analysis. RESULTS The response rate was 82.7%. Nearly two-thirds of pregnant women reported using herbal medicine (62.7%). Herbal medicine users were more likely to be Muslim than Christian. Luffa acutangula (L.) Roxb was the most cited herbal medicine used and was mostly indicated for urinary tract infection and pedal oedema. Perceived effectiveness and safety over conventional medicine (70.2%) was key driver for use, and majority did not disclose their use of herbs to their maternal health professional (95.2%). CONCLUSION Herbal medicine use among pregnant women in this study was widespread. Maternal health providers should be aware of this relatively common practice and routinely discuss and educate pregnant women on the potential risks and benefits associated with the use of herbs.

Exp Ther Med 2017; 14:2385-2391. [PMID: 28962172 PMCID: PMC5609190 DOI: 10.3892/etm.2017.4771] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2016] [Accepted: 03/23/2017] [Indexed: 12/31/2022] Open
Abstract
Osteoporosis is a systemic skeletal disease that leads to increased bone fragility and susceptibility to fracture. Approximately 50% of postmenopausal women develop osteoporosis as a result of postmenopausal estrogen deficiency. To reduce fractures related to osteoporosis in women, previous studies have focused on therapeutic strategies that aim to increase bone formation or decrease bone resorption. However, pharmacological agents that aim to improve bone fracture susceptibility exhibit side effects. Current studies are investigating natural alternatives that possess the benefits of selective estrogen receptor modulators (SERMs) without the adverse effects. Recent studies have indicated that phytoestrogen may be an ideal natural SERM for the treatment of osteoporosis. In Chinese herbal medicine, psoralen, as the predominant substance of Psoralea corylifolia, is considered to be a phytoestrogen and is used as a remedy for osteoporosis. A number of studies have demonstrated the efficacy of psoralen in bone formation. However, the pathways and underlying molecular mechanisms that participate in psoralen-induced osteoblast formation are not well understood. In the present study, hFOB1.19 cells were treated with psoralen at different concentrations (0, 5, 10, 15 and 20 µM) for 0, 24, 36, 48 and 72 h, respectively. Reverse transcription-quantitative polymerase chain reaction and western blot assays were performed to detect glucose transporter 3 (GLUT3) expression. A cell counting kit-8 assay was used to analyze cell proliferation. In addition the effects of mitogen activated protein kinase inhibitors on extracellular signal-regulated kinase (ERK), phosphorylated (p)-ERK, p38, p-p38, c-Jun N-terminal kinase (JNK) and p-JNK expressions and cell proliferation were measured, as was the effect of nuclear factor (NF)-κB inhibitor on P65 and GLUT3 expressions and cell proliferation. The results indicated that psoralen stimulates hFOB1.19 cell proliferation in a dose-dependent manner (P<0.05). Phospho-ERK, p38 and JNK were markedly increased by psoralen compared with the control group (P<0.05), and the specific inhibitors of ERK (SCH772984), p38 (SB203580) and JNK (SP600125) reversed the stimulatory effects of psoralen on signal marker phosphorylation (P<0.05). The rate of psoralen-induced cell proliferation was significantly suppressed by inhibitors of ERK, JNK and p38 compared with psoralen treatment alone (P<0.05). In addition, psoralen stimulated osteoblast proliferation via the NF-κB signaling pathway. Therefore, the present findings suggest that psoralen may be a potential natural alternative to SERMs in the treatment of osteoporosis and fractures.

Antimalarial Properties of Aqueous Crude Extracts of Gynostemma pentaphyllum and Moringa oleifera Leaves in Combination with Artesunate in Plasmodium berghei-Infected Mice. J Trop Med 2016; 2016:8031392. [PMID: 27872647 PMCID: PMC5107876 DOI: 10.1155/2016/8031392] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2016] [Accepted: 10/20/2016] [Indexed: 02/04/2023] Open
Abstract
Due to the emergence and spread of malaria parasite with resistance to antimalarial drugs, discovery and development of new, safe, and affordable antimalarial are urgently needed. In this respect, medicinal plant extracts are targets to optimize antimalarial actions and restore efficacy of standard antimalarial drugs. The present study was aimed at determining the antimalarial activities of Gynostemma pentaphyllum and Moringa oleifera leaf extracts in combination with artesunate against Plasmodium berghei-infected mice. P. berghei ANKA maintained by serial passage in ICR mice were used based on intraperitoneal injection of 1 × 107 parasitized erythrocytes and subsequent development of parasitemia. These infected mice were used to investigate the antimalarial activity of artesunate (6 mg/kg) in combination with 500, 1,000, and 2,000 mg/kg of G. pentaphyllum and M. oleifera leaf extracts using 4-day suppressive test. It was found that these extracts showed significant (P < 0.05) antimalarial activity in dose-dependent manner with percentage of suppression of 45, 50, and 55% for G. pentaphyllum leaf extract and 35, 40, and 50% for M. oleifera leaf extract. Additionally, artesunate combined with these extracts presented higher antimalarial activity, compared to extract treated alone with percentage of suppression of 78, 91, and 96% for G. pentaphyllum leaf extract and 73, 82, and 91% for M. oleifera leaf extract. The results indicated that combination treatment of G. pentaphyllum or M. oleifera leaf extracts with artesunate was able to increase the antimalarial activity by using low dose of artesunate. Hence, these results justified the combination of these extracts and artesunate in antimalarial herbal remedies.

JOURNAL OF ETHNOPHARMACOLOGY 2016; 181:263-73. [PMID: 26732630 DOI: 10.1016/j.jep.2015.12.051] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 11/23/2015] [Accepted: 12/24/2015] [Indexed: 05/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Togo, many persons still rely on plants for healing, however very little is known about the medicinal practices of the indigenous people. The present study aimed to document the medicinal plant utilization for the management of liver diseases in the Maritime region of the country. METHODOLOGY This was an ethnobotanical survey conducted in the Maritime region of Togo from June to August 2015. The data were gathered from 104 traditional healers (TH) by direct interviews using a semi-structured questionnaire. The calculated use values (UV) were used to analyze the importance of the cited plants. RESULTS A total of 99 plant species belonging to 88 genera and 49 families were cited by the TH as curing the hepatic diseases. The most represented families were Caesalpiniaceae with 8 species, followed by Euphorbiaceae with 7 species, Apocynaceae and Asteraceae with 6 species each. The highest UV were recorded with Gomphrena celosioides (0.13), Xylopia ethiopica (0.12), Senna occidentalis (0.12), Bridelia ferruginea (0.12), Cymbopogon citratus (0.12), Kigellia Africana (0.09), Cassia sieberiana (0.08) and Sanseviera liberica (0.08), showing their importance in the management of liver dysfunction in the surveyed region. The main used parts were the leaves, followed by the roots, the whole plant, the rhizome and the bark, accounting for more than 10% each. The herbal medicines were mostly prepared in the form of decoction and administrated by oral route. CONCLUSION This study showed that Maritime region of Togo has an important plant biodiversity that is exploited by the indigenous TH. However, some plants cited by the TH have not been studied for their possible hepatoprotective effects. These plants are therefore a starting point for biological screenings.
