RESUMO

BACKGROUND: The western Gironès is a district located in NE Catalonia (NE Iberian Peninsula). This area comprising 186.55 km2 and 10,659 inhabitants is composed of 5 municipalities encompassing 29 villages, located in the hydrographic basins of the Ter and Llémena rivers. METHODS: Following the methodology based on the semi-structured interviews, we carried out 40 interviews with 57 informants, 31 were women and the remaining 26 were men, with an average age of 78.6 years. RESULTS: In the present study, data from 316 taxa (301 angiosperms, 8 gymnosperms, and 7 pteridophytes) belonging to 89 botanical families were collected. The interviewed informants referred 3776 UR of 298 taxa, 1933 (51.19%) of them corresponding to the food category, 949 (25.13%) to the medicinal ones, and 894 (23.68%) to other uses. In addition, 581 vernacular names for 306 species, subspecies, and varieties have also been collected. CONCLUSIONS: These results reveal the validity of traditional knowledge in the studied area, which can be seriously threatened by the loss of its rural condition and its proximity to industrialized areas.

RESUMO

Multidisciplinary studies including archeology and ethnobotany that seek to understand human interventions on the landscape have obtained important results concerning Amazon biodiversity. This study aims to identify the useful plants in different phytophysiognomies related to archeological sites in the Serra de Carajás, in the state of Pará, as well as expand knowledge of the local flora. Information was collected in 76 parcels located in the influence areas of 15 archaeological sites: 45 in forest vegetation, 30 in canga vegetation and 1 in palm swamps. The species were categorized as either medicinal, food, game attractants, firewood, toxic, ritualistic and material. An assessment of the plants use potential by family was done using regression analysis for the taxa inventoried. All the phytophysiognomies studied in the vicinity of archaeological sites were expressive regarding useful species. The most representative categories were medicinal, material, game attractant, firewood and food. The floristic features related to the use of plant species by family were also expressive for Fabaceae, Myrtaceae and Chrysobalanaceae. The phytophysiognomies identified near archaeological sites feature several plant resources in different use categories, highlighting the value of local ecosystems and their potential for human use.

RESUMO

BACKGROUND: Archipelagos of islands have played an important role in shaping some of the paradigms of biology, including the theory of the evolution of species. Later, their importance in biology was further emphasised by the theory of island biogeography, which contributed to a better understanding of the shaping of species richness not only on real islands, but on isolated habitat islands as well. Although ethnobotany is a well-established discipline, patterns of knowledge about plant uses in archipelagos have never been quantitatively analysed, and the whole concept has been only briefly mentioned in the ethnobiological context. The aim of our study was to record which taxa of wild vegetables have been consumed in the Adriatic islands and to establish if such variables as island size, population size, flora or its isolation are correlated with the number of wild vegetables used. METHODS: We interviewed 225 people (15 from each island). RESULTS: Altogether, the use of 89 species of wild vegetables has been recorded. The largest number of wild vegetables is eaten on the islands of Korcula, Vis and Solta, and the lowest on Ugljan, Cres and Dugi Otok. The studied independent variables had a small and statistically not significant effect on the wild vegetable list length. The most visible effect was an increasing trend from north-west to south-east, overrunning the typical biogeographical island patterns. Moreover, one of the large and well-populated islands, Korcula, showed an 'unusually' high level of wild vegetable use. We hypothesise that the current use of so many species on this island has been maintained by the inhabitants' awareness that they are the holders of relic knowledge, an awareness reiterated by ethnographic and popular publications, as well as a strong history of famine. The most interesting edible species used in the Adriatic islands are Bunium alpinum, Cytinus hypocystis (both mainly on Pasman), Lotus edulis (on Vis) and Posidonia oceanica (on Vis and Korcula). CONCLUSIONS: The recorded relationships between the demographic and geographical features of the islands were statistically not significant. We assume that cultural and historical factors diversifying the use of plants in particular islands are stronger than the above-mentioned measurable variables.

RESUMO

ETHNOPHARMACOLOGICAL IMPORTANCE: The Caatinga (semi-arid region), is an exclusively Brazilian biome. Considering the scarcity of ethnobotanical and ethnopharmacological studies in this region before the year 2000, this study presents data from ethnobotanical expeditions carried out between 1980 and 1990, by the late professor Francisco José de Abreu Matos (1924-2008). The information revealed in this present work are valuable and remained unpublished until now. MATERIALS AND METHODS: The objective was to organize, systematize and analyze ethnobotanical and ethnopharmacological data using ethnobotanical analytical techniques. The most cited native species in each use category were selected for literature review of the pharmacological studies related to their ethnomedicinal uses. RESULTS: Revision of the botanical nomenclature led to the botanical confirmation of 272 plants, of which 84 (30.9%) were reclassified. These represented 71 families and 220 genera that were cited 1957 times. 153 (56.3%) of these plant species are native to Brazil, of which 36 (23.4%) are endemic to the Caatinga. The use reports (RU) associated with these plants, according to the body systems (ICPC-2) in decreasing order of UR and the ICF values were respiratory system (93 species, 407 UR, ICF 0.77), digestive system (119 species, 373 UR, ICF 0.68), general and nonspecific symptoms (95 species, 219 UR, ICF 0.58), female genital system (60 species, 184 UR, ICF 0.68), skin (71 species, 156 UR, ICF 0.55), cardiovascular (50 species, 99 UR, ICF 0.50), blood and immune system diseases (46 species, 96 UR, ICF 0.53), urological (44 species, 88 UR, ICF 0.51), musculoskeletal (33 species, 80 UR, ICF 0.60), psychological (21 species, 71 UR, ICF 0.60), while others represent less than 10.0% of the UR. The most cited plants in the disease categories were Dysphania ambrosioides (28), Pombalia calceolaria (28) Hymenaea courbaril (26), Myracrodruon urundeuva (50), Brassica juncea subsp. integrifolia (16), Scoparia dulcis (22), Phyllanthus niruri (14), Egletes viscosa (25), Lippia alba (16), Erythroxylum vacciniifolium (9) and Salvia rosmarinus (21). The most prominent clades of the medicinal plants based on cluster analysis were the Lamiids (Euasterids)-497 UR and the Fabids (Eurosids I) - 468 UR. Association between certain phylogenetic clades and use-category were also observed and discussed. CONCLUSION: This study demonstrated a new approach in ethnopharmacology by mapping plant usages to diseases prevalent in a community from old ethnobotanical travel reports. In addition to revealing the therapeutic potential of Caatinga species using cluster analysis.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Magnoliae Officinalis Cortex (the dried bark of Magnolia officinalis), a widely used traditional Chinese medicine, is also known as 'Houpo' (Chinese: ). Magnoliae Officinalis Cortex has a wide range of pharmacological effects and has been used to treat conditions such as abdominal distention, vomiting, diarrhea, food accumulation, Qi stagnation, constipation, phlegm and fluid retention and cough resulting from asthma. AIMS OF THE REVIEW: The present paper reviews advances in research relating to the botany, ethnopharmacology, phytochemistry, pharmacology and toxicology of Magnoliae Officinalis Cortex. Prospects for future investigation and application of this herb are also discussed. MATERIALS AND METHODS: Information on Magnoliae Officinalis Cortex was obtained from published materials, including ancient and modern books; PhD and MSc dissertations; monographs on medicinal plants; the pharmacopoeia of different countries and electronic databases, such as SCI finder, PubMed, Web of Science, ACS, Science Direct, Wiley, Springer, Taylor, AGRIS, Europe PMC, EBSCO host, CNKI, WanFang DATA, J-STAGE and Google Scholar. RESULTS: More than 200 chemical compounds have been isolated from Magnoliae Officinalis Cortex, including lignans, phenylethanoid glycosides, phenolic glycosides, alkaloids, steroids and essential oils. The plant has been reported to have pharmacological effects on the digestive system, nervous system and cardiovascular and cerebrovascular systems, as well as antibacterial, anti-tumour, analgesic, anti-inflammatory and anti-oxidative effects. CONCLUSIONS: Magnoliae Officinalis Cortex is an essential traditional Chinese medicine with pharmacological activities that mainly affect the digestive system, nervous system and cardiovascular and cerebrovascular systems. This review summarises its botany, ethnopharmacology, phytochemistry, pharmacology and toxicology. These information suggest that we should focus on the development of new drugs related to Magnoliae Officinalis Cortex, including specific constituents, so that Magnoliae Officinalis Cortex can exert greater therapeutic potential. Meanwhile, it is important to pay attention to the rational use of Magnolia resources, avoiding over-harvesting which could lead to lack of resources. We should also pursue research on Magnolia substitutes and develop resources such as Magnoliae Officinalis Flos and Magnolia Leaf.

RESUMO

MAIN CONCLUSION: Over the last 25 years, the process of domesticating culturally-important, highly-nutritious, indigenous food-tree species. Integrating these over-looked 'Cinderella' species into conventional farming systems as new crops is playing a critical role in raising the productivity of staple food crops and improving the livelihoods of poor smallholder farmers. This experience has important policy implications for the sustainability of tropical/sub-tropical agriculture, the rural economy and the global environment. A participatory domestication process has been implemented in local communities using appropriate horticultural technologies to characterize genetic variation in non-timber forest products and produce putative cultivars by the vegetative propagation of elite trees in rural resource centers. When integrated into mainstream agriculture, these new crops diversify farmers' fields and generate income. Together, these outcomes address land degradation and social deprivation-two of the main constraints to staple food production-through beneficial effects on soil fertility, agroecosystem functions, community livelihoods, local trade and employment. Thus, the cultivation of these 'socially modified crops' offers a new strategy for the sustainable intensification of tropical agriculture based on the maximization of total factor productivity with minimal environmental and social trade-offs.

RESUMO

Following is submitted an ethnobotanic study on knowledge and practices on usage, role and meaning of plants and relatives used by practitioners of non-official medicine in urban and peri-urban places of the city of Córdoba, Argentina. In this study area, it can be observed a cultural structure of knowledge as well as local and foreign practices, which are typical of modern cultures. Diverse social actors perform as cultural connectors between urban and rural scenarios, which match traditional components with those of biomedicine as well as those that belong to a large chain of medical herbs marketing. Quantitative and qualitative methods were resorted to, through classical ethnobotanic techniques. An amount of 768 therapeutical usages were registered which correspond to 262 native and foreign medical taxons. These taxons belong to 95 family plants marketed within urban and peri-urban areas. It is also remarkable an urban pharmacopeia highly diverse as regards species and usages with a top level of exotic species (60%) as well as complementary alternative and global medicines in theses contexts.


Se presenta un estudio etnobotánico de los conocimientos y prácticas referidos al uso, rol y significado de los vegetales usados por practicantes de la medicina no oficial en poblaciones urbanas y periurbanas de la ciudad de Córdoba, Argentina. En este ámbito de estudio, se conforma un complejo cultural de saberes y prácticas locales y foráneas, típicas de culturas modernas. Se destaca el protagonismo de diversos actores sociales los que actúan como conectores culturales entre escenarios urbanos y rurales, los que combinan elementos tradicionales con los de la biomedicina, como así también los que forman parte de una larga cadena de comercialización de hierbas medicinales. Se recurrió a métodos cualitativos y cuantitativos mediante técnicas clásicas etnobotánicas. Se documentaron un total de 768 usos terapéuticos correspondientes a 262 taxones medicinales de estatus autóctonos y exóticos que pertenecen a 95 familias de plantas comercializadas en el ámbito urbano y periurbano. Se advierte una farmacopea urbana altamente diversificada en especies y aplicaciones con un predominio de especies exóticas (60%) como así también la presencia influyente de las medicinas alternativas complementarias y de medicinas globales en estos contextos.

RESUMO

The antioxidant potential of leaf, stem, root and flower extracts of Quisqualis indica Linn. was assessed to verify its ethnopharmacological importance. Both polar and non-polar solvents like n-hexane, chloroform, ethanol and distilled water were used to obtain crude extracts. The chloroform extract of leaves showed the maximum %age yield, i.e. 27.3% while the n-hexane extract of stem showed the minimum yield, i.e. 0.2%. Five activities including DPPH free radical scavenging activity, ABTS+ assay, Total flavonoid components (TFC), Total phenolic components (TPC) and Metal chelating Assay (MC) were employed to evaluate the antioxidant activity of the plant. The ethanol extract of inflorescence of the plant displayed most elevated DPPH potential, i.e. 452.11%. Aqueous extract of root had highest value of TEAC i.e., 7.4515 mmol. The aqueous extract of flower displayed the highest level of phenolic contents with the value of 35 in terms of GAE mg/mL. On the other hand, the chloroform extract had the highest % bound iron value of 128 and the aqueous extract of flower showed a high concentration of Flavonoids having the value 347.65mg/l of Quercetin. It has been inferred that all parts of Quisqualis indica L. possess good antioxidant potential. Differents parts showed different antioxidant potentials hence they can be used as curative agents against human and animal ailments.

RESUMO

BACKGROUND: Ethnobotanical field studies concerning migrant groups are crucial for understanding temporal changes of folk plant knowledge as well as for analyzing adaptation processes. Italy still lacks in-depth studies on migrant food habits that also evaluate the ingredients which newcomers use in their domestic culinary and herbal practices. METHODS: Semi-structured and open in-depth interviews were conducted with 104 first- and second-generation migrants belonging to the Albanian and Moroccan communities living in Turin and Bra, NW Italy. The sample included both ethnic groups and genders equally. RESULTS: While the number of plant ingredients was similar in the two communities (44 plant items among Albanians vs 47 plant items among Moroccans), data diverged remarkably on three trajectories: (a) frequency of quotation (a large majority of the ingredients were frequently or moderately mentioned by Moroccan migrants whereas Albanians rarely mentioned them as still in use in Italy); (b) ways through which the home country plant ingredients were acquired (while most of the ingredients were purchased by Moroccans in local markets and shops, ingredients used by Albanians were for the most part informally "imported" during family visits from Albania); (c) quantitative and qualitative differences in the plant reports mentioned by the two communities, with plant reports recorded in the domestic arena of Moroccans nearly doubling the reports recorded among Albanians and most of the plant ingredients mentioned by Moroccans representing "medicinal foods". CONCLUSION: A large portion of the differences shown by the two communities are linked to different methods of procurement of home country gastronomic botanical ingredients, the different transnational informal exchanges that exist between Italy and migrants' home countries, the presence of markets and ethnic shops in Italy selling these items, and the different degree of difficulty in accessing public health services. The observed divergences were also clearly related to very diverse adaptation strategies, i.e., processes of negotiating and elaborating Albanian and Moroccan cultural identities.

RESUMO

BACKGROUND: Indigo-dyed textiles have been central to the cultural identity of Landian Yao (literally "blue clothes Yao") people in Southwest China for centuries, driving a significant local market for naturally dyed indigo cloth. In the past two decades, local indigo production for traditional textiles has declined for several reasons: Firstly, the younger generation of Landian Yao has shifted to using western style jeans and T-shirts. Secondly, due to its labor-intensive nature. In contrast, at a global scale, including in China, there has been a revival of interest in natural indigo use. This is due to a growing awareness in the fashion industry about human and environmental health issues related to synthetic dye production. Ironically, this new awareness comes at a time when traditional knowledge of indigo dyeing is being lost in many places in China, with weaving and use of natural dyes now limited to some remote areas. In this study, we recorded indigo dyeing processes used by Landian Yao people and documented the plant species used for indigo dyeing. METHODS: Field surveys were conducted to the study area from September 2015 to November 2016, supplemented by follow-up visits in July 2018 and November 2018. We interviewed 46 key informants between 36 and 82 years old who still continued traditional indigo dyeing practices. Most were elderly people. Semi-structured interviews were used. During the field study, we kept a detailed account of the methods used by Landian Yao dyers. The data were then analyzed by using utilization frequency to determine the best traditional recipe of indigo dye extraction. All the specimens of documented species were collected and deposited at the herbarium of Kunming Institute of Botany. RESULTS: Our results showed that indigo dyeing was divided into two main steps: (1) indigo pigment extraction and (2) dyeing cloth. The general procedures of indigo dye extraction included building or buying a dye vat, fermentation, removal of the leaves of indigo producing plant species, addition of lime, oxygenation, followed by collection, and the storage of the indigo paste. The procedures of dyeing cloth included preparing the dye solutions, dyeing cloth, washing, and air drying. It is notable that Landian Yao dyers formerly only performed the dyeing process on the goat days in the lunar calendar from June to October. After comparing the range of local indigo extraction methods, our results showed that the following was best of these traditional recipes: a indigo-yielding plant material to tap water ratio of 30 kg: 200 l, lime 3 kg, a fermentation time of 2-3 d, aeration by agitation for up to 60 min, and a precipitation time of 2-3 h. Our results show that 17 plant species in 11 families were recorded in the indigo dyeing process. With the exception of the indigo sources, only Dioscorea cirrhosa Lour. and Artemisia argyi H.Lév. & Vaniot were previously recorded in dyeing processes. Other species given in this paper are recorded for the first time in terms of their use in the indigo dyeing process. In the study area, Landian Yao men were in charge of indigo dye extraction, and the women were responsible for dyeing cloth. CONCLUSIONS: The Landian Yao has completely mastered the traditional indigo dyeing craft and are one of the well-deserved identity blues. Indigo production from plants using traditional methods is a slow process compared to synthetic dyes and is not suitable for modern and rapid industrial production. Therefore, our study records the detailed information of traditional indigo dyeing to protect and inherit it. Strobilanthes cusia (Nees) Kuntze is the main indigo source in Landian Yao that is widely used in the world and can be commercially exploited as an indigo plant. For commercial and environment benefits, we suggest that producing natural indigo for the commercial market is a good choice.

RESUMO

BACKGROUND: The wild plants not only form an integral part of the culture and traditions of the Himalayan tribal communities but also contribute largely to the sustenance of these communities. The tribal people use large varieties of wild fruits, vegetables, fodder, medicinal plants, etc. for meeting their day-to-day requirements. The present study was conducted in Churah subdivision of district Chamba where large populations of Muslim Gujjars inhabit various remote villages. These tribal people are semi-pastoralists, and they seasonally (early summers) migrate to the upper altitudes (Adhwari's) along with their cattle and return to permanent settlements before the onset of winters. A major source of subsistence of these tribal people is on natural resources to a wide extent, and thus, they have wide ethnobotanical knowledge. Therefore, the current study was aimed to report the ethnobotanical knowledge of plants among the Gujjar tribe in Churah subdivision of district Chamba, Himachal Pradesh. METHODS: Extensive field surveys were conducted in 15 remote villages dominant in Gujjar population from June 2016 to September 2017. The Gujjars of the area having ethnobotanical knowledge of the plants were interrogated especially during their stay at the higher altitudes (Adhwari's) through well-structured questionnaires, interviews, and group meetings. The data generated was examined using quantitative tools such as use value, fidelity, and informant consensus factor (Fic). RESULTS: This study reveals 83 plants belonging to 75 genera and 49 families that were observed to have ethnobotanical uses. Plants were listed in five categories as per their use by the Gujjars, i.e. food plants, fruit plants, fodder plants, household, and ethnomedicinal plants. The leaves, fruits, and roots were the most commonly used plant parts in the various preparations. The highest number of plants was recorded from the family Rosaceae followed by Polygonaceae and Betulaceae. On the basis of use value (UV), the most important plants in the study area were Pteridium aquilinum, Juglans regia, Corylus jacquemontii, Urtica dioica, Diplazium maximum, and Angelica glauca. Maximum plant species (32) were reported for ethnomedicinal uses followed by food plants (22 species), household purposes (16 species), edible fruits (15 species), and as fodder plants (14 species). The agreement of the informants conceded the most from the use of various plants used as food plants and fruit plants (Fic = 0.99), followed by fodder plants and household uses (Fic = 0.98) while it was least for the use of plants in ethnomedicine (Fic = 0.97). The fidelity value varied from 8 to 100% in all the use categories. Phytolacca acinosa (100%), Stellaria media (100%), and Urtica dioica (100%) were among the species with high fidelity level used as food plants, while the important species used as fruit plants in the study area were Berberis lycium (100%), Prunus armeniaca (100%), and Rubus ellipticus (100%). Some important fodder plants with high fidelity values (100%) were Acer caesium, Aesculus indica, Ailanthus altissima, and Quercus semecarpifolia. The comparison of age interval with the number of plant use revealed the obvious transfer of traditional knowledge among the younger generation, but it was mostly concentrated in the informants within the age group of 60-79 years. CONCLUSIONS: Value addition and product development of wild fruit plants can provide an alternate source of livelihood for the rural people. The identification of the active components of the plants used by the people may provide some useful leads for the development of new drugs which can help in the well-being of mankind. Thus, bioprospection, phytochemical profiling, and evaluation of economically viable products can lead to the optimum harnessing of Himalayan bioresources in this region.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The Zeliangrong people with their yearlong experiences still depend on the medicinal plants for primary healthcare. Some of the medicinal plants used by the community exhibits established pharmacological activities which signify the importance of the traditional knowledge of the tribes. Besides, many other species traditionally used by the tribes assume to have pharmacological potentiality. AIM OF THE STUDY: The study aimed to identify the medicinally and pharmacologically important species with understanding the traditional healing practices and to compare medicinal plant knowledge among the informants of the three tribes under Zeliangrong group. MATERIAL AND METHODS: Data were collected by interviewing selected 27 herbal healers using modified semi-structured questionnaires. Identification and documentation of all the species have been made using standard taxonomic procedure. Ethnomedicinal uses of all the recorded species was analyzed with computation of the use reports for each species and Informant Consensus Factor. RESULTS: The study recorded 145 medicinal plants used in healing practices by the Zeliangrong tribes. Except 2 species, all are Angiospermic plants found mostly in wild condition. These medicinal plants are used for treating about 59 different health ailments categorized under 13 ICPC disease categories. Highest ICF (0.75) was found in Digestive disorder with 174 use reports for 44 plant species. Besides the established medicinal plants in the Indian System of medicine like Acorus calamus, Centella asiatica, Oroxylum indicum and Phyllanthus emblica, a number of other species like Ageratum conizoides, Blumeopsis flava, Clerodendrum glandulosum, Gynura cusimbua, Hedyotis scandens and Paederia foetida also has maximum use reports. Among the species with higher use reports, 2 species namely Clerodendrum glandulosum and Paederia foetida are exclusively used for the treatment of hypertension, and bone fracture and sprain respectively indicating their remarkable medicinal values and acceptability. Out of the total 145 species, only 24 are shared by all the three tribes with 11 species used for similar diseases. CONCLUSION: The medicinal plants with higher use reports can be evaluated for validation of pharmacological activities and their toxicity. The Indigenous Knowledge System of Zeliangrong community for herbal remedies may be of immense value in pharmacological experimentation particularly for the uses like malaria, health tonic, cancer, jaundice, hypertension and diabetes.

RESUMO

BACKGROUND: Because of diverse topographical habitats, the Chenab River wetland harbors a wealth of medicinal and food plant species. This paper presents first quantitative assessment on the ethnobotanical use of plants by the local peoples residing in the Chenab riverine area. METHODS: The ethnobotanical data were collected from six parts of the Chenab River wetland: Mandi Bahuddin, Gujranwala, Gujrat, Sargodha, and Sialkot during 2014 to 2015, using semi-structured interviews. Quantitative indices including informant consensus factor (FCI), relative frequency of citation (RFC), relative importance level (RIL), use value (UV), fidelity level (FL), and corrected fidelity level (CFL) were used to analyze the data. RESULTS: On the whole, 129 medicinal plant species belonging to 112 genera of 59 families were reported, with herbs as dominant life forms (51%). Poaceae was the leading family with 13 species, and leaves were the most frequently utilized plant parts (28%). Herbal medicines were mostly used in the form of powder or decoction, and were mainly taken orally. Withania somnifera, Solanum surattense, Solanum nigrum, Azadirachta indica, Ficus benghalensis, Morus nigra, Morus alba, Polygonum plebeium, and Tribulus terrestris were among the highly utilized plant species, with highest UV, RFC, RIL, FL, and CFL values. The reported ailments were grouped into 11 categories based on FCI values, whereas highest FIC was recorded for gastrointestinal diseases and glandular diseases (0.41 and 0.34, respectively). The use report (UR) and frequency of citation (FC) depicted strong positive correlation (r = 0.973; p = 0.01). The value of determination (r2 = 0.95) indicating 95% variation in UR can be explained in terms of the FC. CONCLUSION: The significant traditional knowledge possessed by local communities depicts their strong relation with phytodiversity. Reported data could be helpful in sustainable use and protection of plant species in the Chenab wetland, with special emphasis on medicinal plants. Furthermore, screening of plant-borne active ingredients and in vivo/in vitro pharmacological activities could be of interest for novel drug synthesis.

RESUMO

BACKGROUND: The present study documents the ethnomedicinal knowledge among the traditional healers of the Pangkhua indigenous community of Bangladesh. The documented data from this area was quantitatively analyzed for the first time. We aimed to record ethnomedicinal information from both the traditional healers and also the elderly men and women of the community, in order to compile and document all available information concerning plant use and preserve it for the coming generations. We aimed to compare how already known species are used compared to elsewhere and particularly to highlight new ethnomedicinal plant species alongside their therapeutic use(s). METHODS: All ethnomedicinal information was collected following established techniques. Open-ended and semi-structured techniques were primarily utilized. Data was analyzed using different quantitative indices. The level of homogeneity between information provided by different informants was calculated using the Informant Consensus Factor. All recorded plant species are presented in tabular format, alongside corresponding ethnomedicinal usage information. RESULTS: This investigation revealed the traditional use of 117 plant species, distributed among 104 genera and belonging to 54 families. There was strong agreement among the informants regarding ethnomedicinal uses of plants, with Factor of Informant Consensus (FIC) values ranging from 0.50 to 0.66, with the highest number of species (49) being used for the treatment of digestive system disorders (FIC 0.66). In contrast, the least agreement (FIC = 0.50) between informants regarding therapeutic uses was observed for plants used to treat urinary disorders. The present study was compared with 43 prior ethnomedicinal studies, conducted both nationally and in neighboring countries, and the results revealed that the Jaccard index (JI) ranged from 1.65 to 33.00. The highest degree of similarity (33.00) was found with another study conducted in Bangladesh, while the lowest degree of similarity (1.65) was found with a study conducted in Pakistan. This study recorded 12 new ethnomedicinal plant species, of which 6 have never been studied pharmacologically to date. CONCLUSIONS: This study showed that the Pangkhua community still depends substantially on ethnomedicinal plants for the treatment of various ailments and diseases and that several of these plants are used in novel ways or represented their first instances of use for medicinal applications.
