Ethnobotanical study of medicinal plants used to treat human ailments in Quara district, northwestern Ethiopia.

BACKGROUND: Ethiopia is recognized as one of the centers of origin for the diversity of many plant species, including medicinal plants. Throughout the country, a large proportion of the population relies on these therapeutic plant species for primary healthcare. While such traditional medicinal knowledge has been documented in some regions, there is a lack of information from the Quara district of northwestern Ethiopia. Therefore, this study aimed to document the indigenous and local knowledge of the use of medicinal plants among three ethnic groups residing in the area. METHODOLOGY: An ethnobotanical study was conducted from August 2022 to October 2023 in ten kebeles of the Quara district. Data were collected through semi-structured interviews, field walks, and focus group discussions with 286 informants using snowball, purposive, and random sampling techniques. Quantitative analyses included Rahman's similarity index (RSI), informant consensus factor (ICF), and direct matrix ranking (DMR). Descriptive statistics were used to analyze basic ethnobotanical data. RESULTS: A total of 128 medicinal plant species from 112 genera and 50 families were documented and used to treat 14 disease categories. There was a 28% overlap in medicinal plant knowledge among the three ethnic groups studied. Fabaceae was the most represented family with 22 species. Trees accounted for the majority of the documented plants (37.5%), and leaves were the most commonly used plant parts (23.1%). Oral administration (56.7%) of plant extracts was the primary mode of remedy preparation and use. The highest ICF value (0.93) was recorded for circulatory and blood-related disorders. The study identified nine plants and 39 therapeutic uses not previously reported in Ethiopia. The RSI showed high overlap with neighboring areas and low similarity with distant areas. Top-ranked multipurpose plants were Ziziphus spina-christi and Terminalia leiocarpa, with agricultural expansion and fuelwood collection identified as major threats. CONCLUSION: The findings demonstrate the rich diversity of medicinal plants and associated traditional knowledge in the Quara district. The high ethnobotanical indices warrant further phytochemical and pharmacological investigations. Integrated conservation efforts are recommended to address the challenges facing these valuable plant resources.

Exploring the lived experiences of women with infertility using traditional healthcare services in Harare urban, Zimbabwe.

Infertility has a significant impact on the lives of women. Therefore, affected women often consider the treatment options available to deal with their condition, including traditional healthcare services (THS). The aim of this phenomenological study was to explore the lived experiences of women with infertility problems who sought help from traditional health practitioners in Harare, Zimbabwe. Data from interviews with five women with infertility was explicated using a simplified version of Hycner (1985) five step explication process. Two major themes and eight sub themes emerged from the findings. The major themes were traditional diagnosis experiences and traditional treatment experiences. Consultation and divination were the diagnosis methods experienced by the women with infertility. The THS offered comprehensive management of infertility through couples therapy, as well as pre- and post-natal therapies, which include lifestyle counselling. The findings also showed that women with infertility commonly receive concurrent treatment, including both allopathic and traditional medicine. This presents an opportunity to explore the convergence of traditional and allopathic approaches in the management of infertility in women.

L'infertilité a un impact significatif sur la vie des femmes. Par conséquent, les femmes affectées envisagent souvent les options de traitement disponibles pour faire face à leur maladie, y compris les services de santé traditionnels (THS). Le but de cette étude phénoménologique était d'explorer les expériences vécues de femmes souffrant de problèmes d'infertilité qui ont demandé l'aide de praticiens de santé traditionnels à Harare, au Zimbabwe. Les données provenant d'entretiens avec cinq femmes infertiles ont été expliquées à l'aide d'une version simplifiée du processus d'explication en cinq étapes de Hycner (1985). Deux thèmes majeurs et huit sous-thèmes ont émergé des résultats. Les thèmes principaux étaient les expériences de diagnostic traditionnel et les expériences de traitement traditionnel. La consultation et la divination étaient les méthodes de diagnostic expérimentées par les femmes infertiles. Le THS proposait une prise en charge complète de l'infertilité grâce à une thérapie de couple, ainsi que des thérapies prénatales et postnatales, qui comprennent des conseils sur le mode de vie. Les résultats ont également montré que les femmes souffrant d'infertilité reçoivent généralement un traitement concomitant, comprenant à la fois la médecine allopathique et la médecine traditionnelle. Cela présente l'occasion d'explorer la convergence des approches traditionnelles et allopathiques dans la gestion de l'infertilité chez la femme.

Perceptions of ethnoveterinary medicine among animal healthcare practitioners in South Africa.

The South African government recognises the value of traditional healing and supports an integrated healthcare system. In the veterinary field, successful integration depends on the perceptions of different animal healthcare practitioners (AHCPs). This study aimed to determine the perceptions of ethnoveterinary medicine among state-employed veterinarians and animal health technicians in the North West province. A mixed model questionnaire and non-probability sampling gathered quantitative and qualitative data from 53 participants. Statistical and thematic analysis processes were applied to quantitative and qualitative data, respectively. Overall, 77.4% of participants were aware of ethnoveterinary medicine practices. Approval of the use of ethnoveterinary medicine by farmers was above-average at a mean of 3.57, standard deviation (s.d.) = 1.016 on a 5-point Likert scale. However, 65.9% doubted the effectiveness of ethnoveterinary medicine, which suggests tolerance but no appreciation of its value. The Chi-square test revealed a significant relationship between district municipality of employment and awareness at χ2 = 17.490, df = 3, p = 0.001. Thematic analysis of comments showed that some participants perceived ethnoveterinary medicine as unscientific and interfering with Western veterinary medicine, while some considered it a good complement to Western veterinary medicine. The study also found that 20.8% of AHCPs use ethnoveterinary medicine to treat certain diseases. In conclusion, the lack of appreciation for ethnoveterinary medicine among AHCPs may hinder government-proposed integration, emphasising the need for programmes to improve perceptions among these stakeholders.Contribution: This is first such study to report on perceptions of ethnoveterinary medicine among AHCPs, and assess their readiness for an integrated animal health system.

Ethnozoological study of medicinal animals used by the inhabitants of the Kucha District, Gamo Zone, Southern Ethiopia.

BACKGROUND: An ethnozoological study of medicinal animals in the Kucha district, Gamo zone, Southern Ethiopia, was conducted to investigate and document the use of traditional medicinal animals and the associated indigenous knowledge. Tribal people still make abundant use of animals and their parts to manage diseases in humans and even livestock. METHOD: A cross sectional study design and purposively sampling techniques were used. Data were collected from 132 respondents based on semi structured questionnaires. Focus group discussions (FGD) and Key informant interviews (KII) were conducted; Fidelity level (FL), Relative frequency of citation (RFC) and Informants' consensus factor (ICF) were used to analyze species preference and importance. RESULTS: A total of 24 medicinal animals were identified with 13 species (54.2%) being mammals of which 5 species (20.8%) dominated. They were followed by arthropods, reptiles and fishes. Seven out of the total were domestic species (29%) and 17 (70%) were wild animals. The majority of these animals, i.e. 22 (91.7%), were used to treat human ailments; whereas 2 (8.3%) were used to treat livestock ailments. The ICF values varied from 0.8 to 1.The highest FL value (98%) was linked to the cow (cattle), the lowest (1.5%) to the scorpion. The RFC value (1.0) was highest for the cow and lowest (0.02) for the scorpion. Honey, milk, and butter were the most commonly used therapeutic animal products, but regarding direct uses, fresh/raw meat dominated. Out of ten ailment categories, headaches had the lowest ICF value (0.8). All others scored at least 0.9. CONCLUSIONS: In rural areas, sick people often do not only have limited access to modern medical facilities, they actually prefer traditional treatments considering them to be more reliable and effective. It is therefore important to focus on documenting, conserving, and safeguarding the indigenous knowledge so that strategies to manage the traditional wisdom can be implemented in the future. To achieve these goals, it is important to make sure that medicinal animal species are available in sufficient numbers and neither threatened by habitat changes or overexploitation.

Traditional healer support to improve HIV viral suppression in rural Uganda (Omuyambi): study protocol for a cluster randomized hybrid effectiveness-implementation trial.

BACKGROUND: Rural African people living with HIV face significant challenges in entering and remaining in HIV care. In rural Uganda, for example, there is a threefold higher prevalence of HIV compared to the national average and lower engagement throughout the HIV continuum of care. There is an urgent need for appropriate interventions to improve entry and retention in HIV care for rural Ugandans with HIV. Though many adults living with HIV in rural areas prioritize seeking care services from traditional healers over formal clinical services, healers have not been integrated into HIV care programs. The Omuyambi trial is investigating the effectiveness of psychosocial support delivered by traditional healers as an adjunct to standard HIV care versus standard clinic-based HIV care alone. Additionally, we are evaluating the implementation process and outcomes, following the Consolidated Framework for Implementation Research. METHODS: This cluster randomized hybrid type 1 effectiveness-implementation trial will be conducted among 44 traditional healers in two districts of southwestern Uganda. Healers were randomized 1:1 into study arms, where healers in the intervention arm will provide 12 months of psychosocial support to adults with unsuppressed HIV viral loads receiving care at their practices. A total of 650 adults with unsuppressed HIV viral loads will be recruited from healer clusters in the Mbarara and Rwampara districts. The primary study outcome is HIV viral load measured at 12 months after enrollment, which will be analyzed by intention-to-treat. Secondary clinical outcome measures include (re)initiation of HIV care, antiretroviral therapy adherence, and retention in care. The implementation outcomes of adoption, fidelity, appropriateness, and acceptability will be evaluated through key informant interviews and structured surveys at baseline, 3, 9, 12, and 24 months. Sustainability will be measured through HIV viral load measurements at 24 months following enrollment. DISCUSSION: The Omuyambi trial is evaluating an approach that could improve HIV outcomes by incorporating previously overlooked community lay supporters into the HIV cascade of care. These findings could provide effectiveness and implementation evidence to guide the development of policies and programs aimed at improving HIV outcomes in rural Uganda and other countries where healers play an essential role in community health. TRIAL REGISTRATION: ClinicalTrials.gov NCT05943548. Registered on July 5, 2023. The current protocol version is 4.0 (September 29, 2023).

Exploring patient referral practices of traditional healthcare practitioners in Soshanguve, Gauteng Province, South Africa.

Introduction: It may be necessary for healthcare professionals to refer patients to other professionals and institutions that are able to provide the care needed by patients, depending on the severity each case presents, healthcare requirements, and resources available to offer care. In healthcare generally, patient referral is standard procedure; however, in South Africa, referral patterns between allopathic and traditional healthcare practitioners are unknown, and this is a problem yet to be addressed. Objectives: The study objective was to explore patient referral practices from the perspectives of traditional healthcare practitioners of South Africa. Methods: A qualitative, exploratory and descriptive design was employed to collect data from 11 traditional healthcare practitioners who were sampled using snowball sampling. An individual semi structured interview schedule was used to collect data. Content analysis was used to analyze the data. Results: Patient referral was common practice in traditional health practices, however not reciprocal between the traditional and allopathic healthcare. Several indications for patient referral to allopathic healthcare practitioners included management of chronic conditions amongst others. Discussion: Patient referral being an important part of healthcare practices should be promoted and regulation and traditional health practices improved to promote safe referral practices and curb unsafe self-referrals by patients.

A scoping review of the use of traditional medicine for the management of ailments in West Africa.

BACKGROUND: The coexistence of traditional healing practices deeply rooted in cultural and historical contexts and the evolving landscape of modern healthcare approaches in West African societies creates a dynamic interplay between tradition and modernity in healthcare. This study aims to comprehensively map the landscape of traditional medicine use for health in West Africa. METHODS: A scoping review was conducted following the Joanna Briggs Institute (JBI) methodology and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Research questions focused on the links between traditional medicine practices and health in West Africa. The systematic literature search covered PubMed, Web of Science, and CINAHL from database inception to September 2023. A descriptive analysis was conducted highlighting the years of publication, countries of publication, study designs of plant families and plant parts used for making traditional medicines, and the diseases the traditional remedies are for. RESULTS: The search identified 3484 records, with 46 articles meeting the inclusion criteria. Publications spanned from 1979 to 2023, with no observed trend in the number of publications over successive decades. Nigeria had the highest number of publications (54.3%), followed by Ghana (19.6%). The studies employed various designs, including clinical trials, ethnobotanical, ethnopharmacological, and experimental designs. Plant families frequently studied included Combretaceae, Euphorbiaceae, and Rubiaceae. Traditional remedies address various health issues, highlighting their versatility, from general symptoms to specific diseases. CONCLUSION: This scoping review offers an extensive overview of traditional healing practices in West Africa. The studies highlighted in this review stress the necessity for culturally sensitive healthcare interventions. The widespread use of traditional medicine and the variety of practices underscore the importance of encouraging collaboration between traditional healers and modern healthcare professionals. This review also identifies knowledge gaps and areas needing further research, setting the stage for future exploration into West Africa's intricate healthcare landscape.

Prevalence of traditional eye medicine and self-treatment in Gurage Zone, Rural Ethiopia.

INTRODUCTION: Traditional medicines are commonly used worldwide, especially in Africa-however, there is limited information on the prevalence and types of traditional eye medicine utilization in Ethiopia. The goal of this study was to determine the prevalence, the type and nature of traditional eye medicine use and practices related to self-medication for ophthalmic diseases in a rural Ethiopian population. METHODS: A cross-sectional study was conducted in six randomly selected primary health centers in rural Gurage Zone, Southern Ethiopia. Health-seeking behavior, use of self-medication, and traditional eye medicine were assessed in the population using a semi-structured questionnaire. Descriptive statistics and multivariable logistic regression analysis were computed to determine associated factors for using self-medication and traditional eye medicine. RESULT: Of the 814 participants interviewed, 487 (59.8%) reported using traditional eye medicine, mainly for combinations of symptoms of ocular redness, irritation, and eye discharge (95.5%). Besides, 604 (74.2%) participants reported self-treatment with tetracycline 1% eye ointment. Older age, females, low income, no formal education, and lack of access to media were risks for utilizing traditional eye medicine. CONCLUSION: The use of traditional eye medicine and self-treatment are common in this population. Regulatory legislation, public awareness, and making eye care are vital activities required to monitor such practices.

Ethnobotany in Angola: The contribution of late 19th century christian missionaries to the knowledge of medicinal wild plants.

ETHNOPHARMACOLOGICAL RELEVANCE: Angola has an extraordinary plant diversity and a great ethnobotanical potential. However, there is a general lack of information about the first botanical explorations in the country and their contribution to the knowledge of the medicinal flora. AIM OF THE STUDY: The main aim of this study was to unveil the ethnobotanical legacy of José Maria Antunes and Eugène Dekindt, priests of the first Catholic mission in Huíla (Angola) and shed light on their contribution to the knowledge of medicinal wild plants of the country, including information on the uses, plant parts used, and preparation methods documented in the late 19th century. The findings are discussed considering recent ethnobotanical studies to offer a more comprehensive understanding of the historical and traditional uses of plants in Angola over the last two centuries. MATERIALS AND METHODS: Based on the information available in manuscripts and on the study of botanical collections preserved in herbaria of Portugal and Angola, we extracted relevant information about the species used in traditional medicine by the rural population of Huíla, the health conditions treated, and the mode of preparation and application. RESULTS: Our results revealed that Antunes and Dekindt conducted the first ethnobotanical study in Huíla, and documented a large number of medicinal wild plants. From these, we report 191 medicinal species, including 25 endemic and four introduced species, belonging to 56 plant families and 146 genera. Fabaceae family presents the highest richness of medicinal plants (39 taxa), followed by Rubiaceae (13), Asteraceae (10), and Apocynaceae (9). The illnesses reported were classified into 15 different categories, with the highest number of species (49) corresponding to unspecific conditions, such as general pains, chills, and fever. Thirty-seven species were reported for respiratory diseases, 31 for musculoskeletal problems, and 30 for digestive issues. Leaves were the most used plant part for medicinal purposes (84 species). Infusion was the most frequently described preparation method (40 species), followed by maceration (24 species), and powdering (36 species). CONCLUSIONS: The legacy of Antunes and Dekindt's work improves our understanding of Angola's botanical richness and traditional uses of plant resources. Our findings highlight the presence of unique medicinal resources in Angola, especially among endemic species, which hold the potential to improve the quality of life of rural communities. Moreover, our research underscores the lack of knowledge of medicinal species, emphasizing the risk of losing valuable historical information.

Ethnomedicinal, phytochemical, pharmacological and toxicological profile of Mondia whitei: A review.

Mondia whitei is an aromatic plant native to sub-Saharan Africa. This spice is commonly used in the treatment of various diseases, such as hypertension, diabetes, erectile dysfunction, and premature ejaculation. This review was undertaken to provide updated information on the botanical, phytochemical, pharmacological, and toxicological knowledge of this plant of high relevance to African populations. Moreover, its mechanism of action was described based on previous experimental studies. Data were compiled from various online databases such as PubMed, Google Scholar, Scopus, Science Direct, Web of Science, Springer link, Taylor and Francis, and SciFinder. Additionally, books, book chapters and proceedings were used as secondary sources. The chemical structures of phytocompounds were drawn using PubChem Sketcher program. M. whitei contains various phytocompounds, including reducing sugars, triterpenes, steroids, alkaloids, saponins, tannins, phenolics, hydrogen cyanide, carotenoid, oxalate and phytate. Moreover, para-pentylphenyl-benzoate, (-)-Loliolide, 5-chloropropacin, propacin, 2-hydroxy-4-methoxybenzaldehyde, isovanillin, 9-hexacosene, 2-hexen-1-ol, and heptacosane were isolated from this spice. M. whitei has several pharmacological benefits, including aphrodisiac, pro-fertile, pro-erectile, androgenic, antioxidant, antiparasitic, antimalarial, antibacterial, antiviral, antifungal, antiepileptic, anti-inflammatory, analgesic, antidepressant, antidiarrheal, hepatoprotective, antisickling, and anticancer activities. Toxicological studies showed an LD50 of above 5000 mg/Kg and no signs of toxicity after one week of oral treatment. The aphrodisiac effect of this spice is one of its main activities, supported by numerous experimental studies. Because M. whitei delays contractions of the bulbospongiosus muscles, its aphrodisiac effect could be mediated through the modulation of the spinal generator of ejaculation. This can justify its folkloric use in the treatment of premature ejaculation.

Integrating traditional medicine into the African healthcare system post-Traditional Medicine Global Summit: challenges and recommendations.

The World Health Organization (WHO) held the inaugural Traditional Medicine Global Summit in India in 2023 to promote the evidence-based integration of traditional medicine (TM) into the global healthcare system. This summit offers many opportunities for Africa, where most people rely on TM for health care. TM is widely accepted and affordable in the region but faces many challenges that limit its potential. This article identifies some of the most pressing challenges to incorporating TM into standard healthcare in Africa. It also proffers useful recommendations on how these issues may be addressed while identifying key stakeholders whose contributions may hamper or enhance the realization of WHO´s goals for TM in the continent.

Indigenous herbal medicine use and its associated factors among pregnant women attending antenatal care at public health facilities in Dire Dawa, Ethiopia: a cross-sectional study.

OBJECTIVE: The aim of this study was to investigate the prevalence of indigenous herbal medicine use and its associated factors among pregnant women attending antenatal care (ANC) at public health facilities in Dire Dawa, Ethiopia. DESIGN: A facility-based cross-sectional study design. SETTING: The study was conducted in seven public health facilities (one referral hospital, three urban and three rural health centres) in Dire Dawa, Ethiopia, from October to November 2022. PARTICIPANTS: 628 pregnant women of any gestational age who had been on ANC follow-up at selected public health facilities were included. MAIN OUTCOME MEASURES: Prevalence of indigenous herbal medicine (users vs non-users) and associated factors. RESULTS: The study revealed that 47.8% (95% CI 43.8% to 51.6%) of pregnant women used herbal medicines. Lack of formal education (adjusted OR, AOR 5.47, 95% CI 2.40 to 12.46), primary level (AOR 4.74, 95% CI 2.15 to 10.44), housewives (AOR 4.15, 95% CI 1.83 to 9.37), number of ANC visits (AOR 2.58, 95% CI 1.27 to 5.25), insufficient knowledge (AOR 4.58, 95% CI 3.02 to 6.77) and favourable perception (AOR 2.54, 95% CI 1.71 to 3.77) were factors significantly associated with herbal medicine use. The most commonly used herbs were garden cress (Lepidium sativum) (32%), bitter leaf (Vernonia amygdalina) (25.2%), moringa (Moringa oleifera) (24.5%). Common indications were related to gastrointestinal problems, blood pressure and sugar. CONCLUSION: The prevalence of herbal medicine use is high (one in two pregnant women) and significantly associated with education level, occupation, ANC visits, knowledge and perceptions. The study's findings are helpful in advancing comprehension of herbal medicines using status, types and enforcing factors. It is essential that health facilities provide herbal counselling during ANC visits, and health regulatory bodies ought to raise awareness and implement interventions to lower the risks from over-the-counter herbal medicine use by pregnant women.

Understanding maternal Ethnomedical Folklore in Central Uganda: a cross-sectional study of herbal remedies for managing Postpartum hemorrhage, inducing uterine contractions and abortion in Najjembe sub-county, Buikwe district.

Pregnant women in rural Uganda largely rely on medicinal plants for inducing labor, treating postpartum hemorrhage (PPH), and inducing abortion. 90% of the women in both rural and urban Uganda use plants to manage pregnancy symptoms like constipation, heartburn, morning sickness, body aches, nausea, and vomiting. After delivery women continue using plants to manage postpartum complications and for infant care especially herbal baths. This study documented how ethnomedical folklore has been used to aid childbirth, manage postpartum hemorrhage, and induce abortion. METHODS: A cross-sectional ethnobotanical survey was conducted from May - December 2023 in Najjemebe sub-county, Buikwe district. 206 respondents from 12 villages were selected using snowball sampling. Key informants included Traditional Birth Attendants (TBAs) and herbalists. Data was collected using semi-structured questionnaires and focus group discussions. Voucher specimens of the plants were identified and authenticated at Makerere University Herbarium. Data were analyzed using descriptive statistics, Informant Consensus factor (ICF), Use Reports (URs), paired comparisons, and GraphPad Prism® version 9.0.0 software. RESULTS: All respondents (N = 206, 100%), used plants to induce labour, treat PPH, and induce abortion. One hundred four plant species were documented: most cited or preferred were: Hoslundia opposita (N = 109, 53%), Phytolacca dodecandra (N = 72, 35%), and Commelina erecta (N = 47, 23%). The plants belonged to 49 families, Lamiaceae (16.3%) and Fabaceae (14.3%) having the majority of the species. Herbs were 42 (40%) and trees 23 (22%). Oral administration 95(72%) was the commonest, then topical 19 (14.4%) and vaginal 14(10.6%). CONCLUSION: Health surveys revealed that about 27% of deliveries in Uganda take place outside a health facility. Due to the oxytocic effects of plant species reported in this study, they play a triple role of being uterotonics, abortifacients, and treating postpartum haemmorhage. The dilemma lies in the unknown dosages and toxicity levels that could endanger both the mother's and the unborn child's lives. Due to Uganda's high rates of population growth, overall fertility, maternal mortality, and morbidity, policies, and programmes on gendered health provision need to be reevaluated. Integrating herbal medicine into health care systems appears to be a feasible solution.

Traditional healers' knowledge and infection control practices related to HIV in Bukavu City, Democratic Republic of the Congo.

BACKGROUND: Patients with HIV consult traditional healers (THs). These THs can both delay care for people living with HIV (PLHIV) and transmit HIV through poor infection control practices. The main objective of this study was to evaluate knowledge and practices of THs regarding HIV in Bukavu. METHODS: A cross-sectional study using quantitative approach was carried out among 71 THs in Bukavu City. The collected data included the following topics: personal and socio-demographic characteristics, HIV knowledge, and infection control practices. Descriptive statistics, independent-samples T-test or F-test, and multiple linear regression were used to analyze the data with a p-value < 0.05. RESULTS: The THs' mean age was 49.2 ± 11.2 years, and the majority were aged 40 to < 60 years. Males constituted 88.7% of THs with a male-to-female ratio of 7.9. In general, 47.9% of study participants had poor knowledge about HIV/AIDS infection, 45.1% of them had fair knowledge, and only 7.0% had good knowledge. Overall, 43.7% of THs had poor infection control practices, 52.1% of THs had fair practices, and only 4.2% of participants had good practices. Results of multiple linear regression analysis revealed that none of the personal and demographic variables studied were significant predictors of their knowledge about HIV/AIDS (p > 0.05). In terms of practices, two variables were significant predictors of infection control practices: living in Ibanda and receiving training in taking care of HIV/AIDS. CONCLUSION AND RECOMMENDATIONS: The study revealed that THs' knowledge about HIV infection was insufficient and that they had poor infection control practices. Formal standardized training on HIV infection should be organized for all THs so that they can always refer their patients to modern, reliable antiretroviral therapy (ART) clinics and reduce the risk of occupational exposure in their practices. Although PPE's assistance for THs is required in terms of protective measures, the province health authority must also oversee infection control procedures at THs' offices.

Ethnomedicine, antibacterial activity, antioxidant potential and phytochemical screening of selected medicinal plants in Dibatie district, Metekel zone, western Ethiopia.

BACKGROUND: Medicinal plants play a major role in the delivery of healthcare, particularly among the rural population of Ethiopia. Plant extracts and their bioactive compounds have been utilized for the treatment of several diseases. This study was aimed at evaluating the antibacterial activity, antioxidant capacity, and phytochemical content of selected medicinal plants used in Dibatie district, western Ethiopia. METHODS: Study plants were collected, shade dried, pulverized, extracted by maceration in 80% ethanol, and subjected to antibacterial, antioxidant, and phytochemical tests. Minimum inhibitory concentration (MIC) was determined using 96-well microplates and nutrient broth microdilution. Antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. Phytochemical screening was conducted using standard test methods. RESULTS: The ethanolic extract of Polystachya steudneri Rchb.f. pseudobulbs was the most active against gram-negative Proteus mirabilis, Salmonella typhimurium, Klebsiella pneumoniae, Escherichia coli, and Shigella flexneri, with MIC values of 8 ± 0, 11 ± 5, 3 ± 1, 3 ± 1, and 2 ± 0 mg/mL, respectively. The ethanolic extract of P. steudneri was also the most effective against gram-positive Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, and Enterococcus faecalis, with MIC values of 8 ± 0, 8 ± 0, 3 ± 1, and 16 ± 0 mg/mL, respectively. Ethanolic extracts of Gnidia involucrata Steud. ex A.Rich. stems and roots were effective antioxidants, with respective 50% DPPH free radical inhibitory concentrations (IC50) of 168.68 and 181.79 µg/mL, followed by that of P. steudneri (IC50 = 203.11 µg/mL). The study plants contained alkaloids, anthocyanins, anthraquinones, cardiac glycosides, coumarins, flavonoids, phenols, saponins, steroids, tannins, and terpenoids. CONCLUSIONS: This study confirmed the antibiotic, antioxidant, and phytochemical constituents of the investigated plants and suggested further investigations that may lead to bioactive lead compounds.

Standardization parameters and synergism of source plant materials for the antidiabetic efficacy of the Rauvolfia-Citrus tea.

The introduction of glucagon-like peptide 1 (GLP-1)-based therapies has greatly improved the management of type 2 diabetes (T2D), as they ensure good blood glucose control and promote weight loss. Ingestion of standardized herbal remedies that promote the same endogenous metabolic processes affected by the GLP-1-based treatments could provide cheaper alternatives in low- and middle-income countries, where there is currently an increase in the incidence of T2D. The focus in this study was to determine quality control parameters and the prime factors for the Rauvolfia-Citrus tea (RC-tea), as used in Nigerian traditional medicine to treat T2D. We have previously shown that the RC-tea that is made by boiling leaves of Rauvolfia vomitoria Afzel. and fruits of Citrus aurantium L. causes normalization of blood glucose and reduction of ectopic lipid accumulation in genetic diabetic (BKS-db) mice and in humans with T2D. The standardized RC-tea was made by boiling 40 g dried R. vomitoria foliage and 200 g fresh C. aurantium fruits per litre. The resulting golden-brown extract is free of microbial contamination, has pH 5 and contains ca. 230 mg naringin (marker compound for C. aurantium) and 25 mg robinin (marker compound for R. vomitoria) per litre. In addition, the herbal extract has the characteristic HPLC-DAD fingerprint where the marker compounds, naringin and robinin have retention times of approximately 26.3 min and 26.9 min, respectively, when using the outlined column and gradient elution conditions. Comparative evaluations of the antidiabetic effects of the standardized RC-tea and boiling water-extracts made with C. aurantium fruits alone (CA), R. vomitoria foliage alone (RV) and a combination of CA and RV, (CA + RV) in BKS-db mice, indicate that components from R. vomitoria foliage drive the reductions in ectopic lipid accumulation, since CA-treated mice lacked this effect. However, the normalization of blood glucose arises from combination of components from the two source plant materials as administration of either CA or RV resulted in hypoglycaemia. Interestingly, treatment with the CA + RV mixture, generated by mixing individually produced CA and RV plant extracts, resulted in hyperglycaemia, possibly due to drug-drug interactions of the blood glucose-reducing components in either plant extract. Hence, our data show that the best antidiabetic outcome results from the traditional practice of boiling R. vomitoria foliage and C. aurantium fruits together.

Anogeissus leiocarpus (DC.) Guill. & Perr. (Combretaceae): A review of the traditional uses, phytochemistry and pharmacology of African birch.

Anogeissus leiocarpus (DC.) Guill. & Perr. belongs to the family Combretaceae and is used both by African traditional medical practitioners and livestock rearers to treat diseases such as African trypanosomiasis, animal diarrhoea, asthma, cancer, cough, diabetes, dysentery, erectile dysfunction, fever, giardiasis, helminthiases, meningitis, menstrual disorders, monkeypox, oral infections, poliomyelitis, sickle cell anaemia, snake bites, toothache, urinary schistosomiasis, and yellow fever. Some of these activities have been associated with the presence of polyphenols in the plant which include ellagic acid derivatives, flavonoids, stilbenes, tannins, and triterpenes. Several bioactive molecules have been identified from A. leiocarpus. These include the main active constituents, ellagitannins, ellagic acid derivates, flavonoids and triterpenes. Pharmacological studies have confirmed its antibacterial, antifungal, antihyperglycemic, antihypertensive, antimalarial, antioxidative, antiparasitic, antitumour and anti-ulcer effects. The stem bark has been investigated mainly for biological activities and phytochemistry, and it is the most mentioned plant part highlighted by the traditional users in ethnomedicinal surveys. In vitro and in vivo models, which revealed a wide range of pharmacological actions against parasites causing helminthiasis, leishmaniasis, malaria and trypanosomiasis, have been used to study compounds from A. leiocarpus. Because of its uses in African traditional medicine and veterinary practices, A. leiocarpus has received considerable attention from researchers.

An updated inventory of medicinal and ritual plants of southern Africa.

ETHNOPHARMACOLOGICAL RELEVANCE: For the first time in two decades, a comprehensive, up-to-date overview of the medicinal and ritual plants of southern Africa is presented. This data is analysed and compared with a previous survey done in 2002. STUDY AIM: The main aim is to update the checklist of medicinal and ritual plants of southern Africa and to determine the number of new records since 2002. We also provide a high-level perspective on the selection of medicinal and ritual plant species in southern Africa, a taxonomic analysis of the new checklist as well as a chronological perspective on the citation of medicinal and ritual species before and after 2002. MATERIALS AND METHODS: The most recently published medicinal and ritual plants checklist for southern Africa was reviewed and updated. A wide range of ethnobotanical literature, including books, field guides and electronic journals, was used. All calculations were done by using formulas and functions in Microsoft Excel and R Studio. RESULTS: 4120 medicinal and ritual taxa and 3784 medicinal and ritual species have been recorded. Compared with the 2002 checklist, there are 1239 new taxa (1228 new species). A strong correlation between available taxa and selected medicinal taxa exists on order level, which corresponds with the results of an analysis done in 2008. The top 10 species-rich medicinal plant families of southern Africa are Asteraceae, Fabaceae, Apocynaceae, Euphorbiaceae, Asphodelaceae, Malvaceae, Lamiaceae, Poaceae, Rutaceae and Rubiaceae. Different patterns of plant family representation can be seen across certain cultural healing systems of southern Africa. The species popularity (number of citations) of Hypoxis hemerocallidea Fisch. & C.A.Mey. Has increased substantially after 2002. Other medicinal and ritual plant species have been consistently researched, such as Artemisia afra Jacq. ex Willd., Carpobrotus edulis (L.) L.Bolus, Aloe ferox Mill., Leonotis leonurus (L.) R.Br. and Gunnera perpensa L. CONCLUSIONS: The numerous new medicinal and ritual plant records that have been reported in the last two decades provide evidence of an incompletely documented ethnobotanical heritage that urgently requires documentation. Patterns of taxonomic diversity on family level indicate distinctive differences between cultural healing systems. Signs of the adaptability and dynamics of traditional healing systems in southern Africa can be seen in the changes in the citation of species over time.

Knowledge and practices of traditional management of child malnutrition and associated pathologies in Benin.

BACKGROUND: Child malnutrition is a major public health challenge, affecting millions of children worldwide, with alarming proportions of children under five in Benin. The complexity of managing this condition is increased by its potential association with opportunistic pathologies. An interesting approach arises from the use of medicinal plants, to address child malnutrition and its associated pathologies. This study aimed to document the knowledge and practices of Beninese mothers and traditional practitioners with regard to the use of medicinal plants to treat child malnutrition and associated diseases. METHODS: A total of 844 Beninese mothers and 201 traditional healers were surveyed between March 2022 and August 2023 in the communes of Karimama, Bopa and Za-Kpota in Benin. The respondents' knowledge of child malnutrition and associated pathologies was explored. The ethnobotanical data collected from the subjects concerned the medicinal recipes used to treat child malnutrition, the medicinal plants that make them up and the methods of use. These data were analyzed using ethnobotanical indices such as the Informant Consensus Factor, the frequency of citation of medicinal recipes types and medicinal plants, and the contribution of plants to medicinal recipes. RESULTS: All respondents cited a total of 82 plant species used to treat child malnutrition and associated diseases. These plants were grouped into 37 botanical families, the most common of which were Fabaceae, Malvaceae and Annonaceae. The leaves were the most commonly used part of the plant species identified. The mothers shared 122 medicinal recipes, ranging from recipes based on a single plant to more complex compositions involving five plants. The most notable plants were Moringa oleifera Lam, Phyllanthus amarus Schumach & Thonn, Senna siamea (Lam.) H.S.Irwin & Barneby, Carica papaya L. and Ocimum gratissimum L. Traditional healers provided 52 plants in 71 recipes, with Moringa oleifera featuring prominently in both single-plant and multiplant formulations. CONCLUSION: This study made it possible to constitute a rich base of medicinal recipes used against malnutrition and associated pathologies, with the preponderant involvement of certain plant species. It is therefore necessary to deepen research on these different identified species in order to scientifically assess their potential.

A scoping review on the use of traditional medicine and oral health in Africa.

BACKGROUND: This review aimed to chart the landscape of literature concerning the precise applications of traditional medicine in managing specific oral diseases and, in doing so, to pinpoint knowledge gaps surrounding the use of traditional medicine for oral disease management in the African context. METHODS: A systematic search of the literature was conducted on PubMed, Web of Science, Scopus, and CINAHL. The search was conducted from the inception of the database till September 2023. A search of related citations and references was also carried out. Only English language publications were included. A summary of studies that met the inclusion criteria was conducted. RESULTS: Of the 584 records identified, 11 were duplicates and 12 studies, published between 2006 and 2021, met the inclusion criteria. The studies were published from eight countries located in the five sub-regions on the continent. All the studies were either experimental designs or ethnobotanical surveys and they all utilized plant-based remedies. The five experimental studies aimed to assess the impact of whole plants or plant extracts on the three microorganisms responsible for dental caries and seven responsible for periodontal diseases. The number of plant species identified by the seven ethnobotanical surveys ranged from 29 to 62 while the number of plan families ranged from 15 to 29. The remedies were either topical applied, use as mouth rinses, gargled, or chewed. The systemic routes of administration identified were inhalation and drinking. The remedies were used for the treatment of hard such as dental caries and tooth sensitivity, to soft tissue lesions such as mouth ulcers, gingival bleeding, and mouth thrush. Other oral disorders managed include halitosis, jaw fracture, and oral cancer. CONCLUSIONS: Given the increasing prevalence of oral diseases within the region, the shortage of oral healthcare professionals and limited access to financial resources, it becomes imperative to support the generation of empirical evidence to enhance the provision of traditional medicine for oral healthcare in Africa.
