AI Article Synopsis

  • * Various quantitative indices, like Informant Consensus Factor (ICF) and Use Value (UV), were used to assess the importance and usage frequency of these plants, highlighting that herbs and leaves are the most commonly utilized parts.
  • * Notably, the research identified 16 species with new therapeutic uses and revealed 7 species that have not been previously studied, emphasizing the continuing relevance of traditional medicine in the area and the potential for further research into these plants.

Article Abstract

This study documents information on significant ethnomedicinal plants, which was collected from the traditional healers of three indigenous communities of Bangladesh. The documented data were quantitatively analyzed for the first time in this area. The information was obtained through open-ended, semi-structured questionnaires. The benefits, importance and coverage of ethnomedicine were expressed through several quantitative indices including Informant Consensus Factor (ICF), Use Value (UV), Frequency of Citation (FC), Relative Frequency of Citation (RFC) and Relative Importance Index (RI). The agreement of homogeneity between the present and previous studies and among the indigenous communities was evaluated using the Jaccard Index (JI). A total of 159 ethnomedicinal plant species, which were distributed in 132 genera under 62 families, were documented from 174 informants. Of these, 128 plants were native and 31 were exotic. Of a majority of documented species, herbs and leaves were the most utilized plant parts for the preparation of ethnomedicines (45.28%) whereas pastes (63.03%) were the most popular formulations. Among the documented species, the dominant families were the Asteraceae (14 species) and the Lamiaceae (12 species). The highest ICF value was 0.77 for digestive system disorders. Based on UVs, the five most commonly used ethnomedicinal plant species in the study area were (0.43), (0.41), (0.40), (0.33) and (0.28). The highest RFC was recorded for (0.25). The highest RI value was calculated for both and (0.83). Importantly, 16 species were reported with new therapeutic uses and to our knowledge, 7 species described herein have never been ethnobotanically and pharmacologically studied, viz: and . The present study showed that traditional treatment using medicinal plants is still widespread in the study area. Documentation of new ethnomedicinal species with their therapeutic uses shall promote further phytochemical and pharmacological investigations and possibly, lead to the development of new drugs.

Genetic counseling is a dynamic and rapidly growing field. In Qatar, the significance of genetic counseling is underscored by the distinctive demographic characteristics of the population, including elevated rates of consanguinity and larger family sizes, contributing to the increased incidence of many genetic conditions. This emphasizes the crucial role of genetic counseling in addressing the specific needs of the community.

Background: Traditional Chinese medicine (TCM) practices such as acupuncture and cupping have been practiced for thousands of years and recently gained more popularity and recognition because of their benefits. However, these practices are not unique to Eastern cultures and countries. The healing practices of folk healers like the of Indigenous communities in Latin America share striking similarities to their TCM counterparts, although not much literature exists on this topic.

Implementing culturally appropriate school-based prevention programs with Indigenous students that leverage culture as a protective factor has the potential to revitalize and sustain cultural connections that have historically and systematically been destroyed in the United States. However, there is a dearth of literature synthesizing the effectiveness of school-based prevention programs that have been implemented with Indigenous students across contexts. As such, we conducted a mixed method systematic review to (a) evaluate school-based prevention programs with quantitative and/or qualitative data, (b) assess the use of Indigenous research methods, and (c) examine cultural and community validity.

White root rot disease caused by Rosellinia necatrix is a growing issue in orchards, and biochar pyrolyzed from the pruned branch residues of fruit trees has potential as a soil amendment agent with a number of benefits, such as long-term carbon sequestration. However, the effects of pruned branch biochar on white root rot disease remain unclear. Therefore, we compared direct antagonism against R.

Implementation of risk mitigation prescribing during dual public health emergencies: A qualitative study among Indigenous people who use drugs and health planners in Northern British Columbia, Canada.

Background: In response to the dual public health emergencies of COVID-19 and the overdose crisis, the Government of British Columbia (BC) introduced risk mitigation prescribing, or prescribed safer supply. In the context of colonialism and racism, Indigenous people are disproportionately impacted by substance use harms and experience significant barriers to receiving care, particularly those living in rural and remote communities. As part of a larger provincial evaluation, we sought to assess the implementation of risk mitigation prescribing as experienced by Indigenous people who use drugs (IPWUD) in Northern BC.
