Local knowledge, practices, challenges of ethnopharmacologically used medicinal plants in Benin and implications for brain illnesses. Sci Rep 2023; 13:19743. [PMID: 37957181 PMCID: PMC10643655 DOI: 10.1038/s41598-023-46647-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
Traditional medicine (TM) is a significant resource for primary healthcare management all over the world, and principally in Africa. Quality improvement activities that promote evidence-based practices and the integration of traditional medicine into primary healthcare systems can help improve the quality of patient care. In the Republic of Benin (West Africa), traditional medicine practitioners (TMPs) provide different treatments and ways of use, depending on the ailments and the medicinal plants used. The present study aimed at documenting the knowledge, attitudes and practices of Beninese TMPs regarding the use of medicinal plants and the challenges associated with their activities. A focus group survey was conducted using semi-structured interviews with a sample of 91 TMPs in 8 departments of the Republic of Benin. The respondents had an average age of 50 years old and belonged to various categories of TMPs. Medicinal plants are harvested depending on the season and time of the day, and are dried in the shade before being used as decoctions or infusions. Nevertheless, the majority of TMPs do not conduct the necessary tests for quality control, efficacy or toxicity of the proposed remedies, which raises several scientific interrogations, particularly for the treatment of mental and brain-related disorders. Among ~ 110 plants used in the treatment of several pathologies, 66 were revealed as threatened species. The challenges faced by TMPs are mainly material, financial and technical difficulties. The present study reports the importance of intervention to modernize TM practices in Benin. Quality improvement could enhance healthcare delivery and provide support for evidence-based interventions aimed at addressing behavioral, social, and environmental determinants of health.

Silambarasan R, Sasidharan S, Nair J H, Kumar S N, R A, Nair AS, Selavinayagam K. A multivariate and quantitative assessment of medicinal plants used by the indigenous Malayali tribes in the Javadhu hills of Tiruvannamalai district, Tamil Nadu, India. Heliyon 2023; 9:e15607. [PMID: 37305490 PMCID: PMC10256831 DOI: 10.1016/j.heliyon.2023.e15607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 04/12/2023] [Accepted: 04/17/2023] [Indexed: 06/13/2023] Open
Abstract
The study of medicinal plants with their traditional uses and related pharmacological studies has received more attention during the past several decades around the world. The Malayali tribes of the Javadhu Hills in the Eastern Ghats rely heavily on a system of traditional medicine for healthcare. A qualitative ethnographic method with a semi-structured questionnaire was used to interview 52 people across 11 localities in the Javadhu Hills. In the data analysis, descriptive statistics such as Use reports (UR), frequency of citations (FC), relative frequency of citations (RFC), informant agreement ratio (IAR), fidelity level (FL), and informant consensus factor (FIC) were studied. In the current investigation, 146 species from 52 families and 108 genera were discovered to treat 79 diseases. Leguminosae and Apocynaceae were the dominant families (12 species each). The most frequently used life form was the herb and the plant part were the leaf. The majority were being harvested from natural resources. Most medicines were taken orally. The most frequently cited species are Moringa oleifera and Syzygium cumini. The illnesses were divided into 21 categories. The majority of the plants mentioned are utilised to increase human immunity and health. The principal ailment (general health) was revealed by two-way cluster analysis and PCA. The species Litsea decanensis, Phoebe paniculata, Commiphora caudata, etc., were new records for the Javadhu hills according to a comparison between the current study and previous local and regional research. Documenting novel ethnomedicinal species and their therapeutic applications will encourage more phytochemical and pharmacological research and may even result in the creation of new medications. Furthermore, the study's significant novelty is that principle component analysis and two-way cluster analysis clearly revealed that the species that are used to treat various diseases, as well as species that are closely associated with treating specific ailment categories, are distinct. Significantly, species recorded in this study rely on maintaining and improving general body health of humans.
