Ethnotaxonomy and Ethnobotanical Studies of Honey and Resinous Plants in the Tchamba Prefecture in Togo

Natural plant products have gained increasing attention, but climate change and human activities have led to the degradation of ecosystems and loss of biodiversity. This study aims to contribute to the preservation of local knowledge related to the classification and use of honey-producing and resinous plants in the Tchamba prefecture, Togo. Ethnotaxonomic and ethnobotanical data were collected through semi-directed interview and focus groups in the four localities, involving 92 respondents. A total of 96 plants of beekeeping were identified, classified into 88 genera, 33 families, and 22 orders, with 16 ethnotaxonomic criteria used for classification. The most common criteria were "plant use" and "plant habit". The study highlights the rich local knowledge of plant uses for food, medicine, and rituals, emphasizing the importance of conserving both biodiversity and cultural heritage. These findings contribute to understanding how indigenous knowledge can support conservation and sustainable use of plant resources.

The importance of sharing: wild plant knowledge in three valleys of Northern Pakistan

Mountain communities are often defined by their distinctive flora and fauna, and the way local people utilize these natural resources. Our study aims to document the indigenous knowledge of wild flora among the local people of three valleys in Northern Pakistan. The ethnobotanical study was conducted in July and August of 2019 and 2020 in 21 hill villages across Shamshal, Hopper, and Phandar valleys in Gilgit-Baltistan, Northern Pakistan. Semi-structured interviews were conducted with 90 key informants. We collected data on traditional knowledge of wild food plants (WFPs), wild medicinal plants (WMPs), and wild veterinary plants (WVPs) among three selected linguistic and religious groups scattered in different villages of the valleys. We documented 79 wild plant taxa belonging to 68 genera and 33 families utilized in the study area, among which, 50% were used as food, 43% were used for veterinary purposes, and 24% for medicinal applications. The data analysis revealed significant differences among the studied valleys and communities. The highest overlap was recorded between the Wakhi and Burushaski communities with a Jaccard Similarity Index (JI) value of 0.265, while the lowest was between the Burushaski and Khowar communities with a JI value of 0.238.

Indigenous Knowledge and the Hann Expedition: Re-Examining Scientific Collections From Colonial Expeditions

An examination of the motivations, dynamics and activities of colonial exploring expeditions can provide valuable insights into the ways in which the colonial mindset shaped the development of natural history collections in colonised lands. The Indigenous Knowledge and the Hann Expedition: Re-examining scientific collections from colonial expeditions project is working to redress these omissions in the historical record by re-contextualising the botanical specimens collected on the 1872 Northern Expedition and re-connecting them with the Aboriginal Country from which they were collected (Dalley et al. 2024). The 1872 Northern Expedition, led by William Hann, sought to establish the mineral and agricultural potential of Cape York Peninsula in northern Queensland, Australia. Alongside Hann, the expedition party included Jerry (Aboriginal guide), Dr Thomas Tate (botanist), Norman Taylor (geologist) and three other European men: Warner, Stewart and Nation. It was this expedition, with its reports of gold on the Palmer River, that triggered Queensland’s biggest goldrush and led to an influx of more than 20,000 settlers, with disastrous consequences for the Aboriginal people who occupied the area (Taylor and Huxley 2020). Between June and November, the expedition party travelled from Mount Surprise north to the Stewart River, before returning south via the coast at Cooktown and Weary Bay (Taylor and Huxley 2020). Geological specimens were collected by Taylor, and botanical specimens were collected by Tate and Taylor (Dowe and Taylor 2019). The botanical specimens collected by Tate and Taylor, now held at Royal Botanic Gardens Kew (K) and the National Herbarium of Victoria (MEL), were enumerated by John Dowe and Peter Taylor (Dowe and Taylor 2019). It has since emerged that the Queensland Herbarium (BRI) holds an additional 18 botanical specimens collected by Tate during the expedition (Council of Heads of Australasian Herbaria 2024). These specimens—along with expedition diaries and maps—will provide a stimulus for regional engagement that explores the intersection between the Hann expedition, colonial science, and the ongoing impacts of colonial violence on Indigenous peoples. The project is being led by three direct descendants of members of the expedition party: Nicole Huxley (descendant of Jerry); Peter Taylor (descendant of Norman Taylor) and Cameo Dalley (descendant of Thomas Tate), making the project uniquely—and powerfully—positioned to examine the personal, scientific and sociopolitical legacies of the expedition (Dalley 2021). It was co-designed with Balkanu Cape York Development Corporation and the three herbaria that house the expedition’s botanical collections. Through engaging in truth-telling with Aboriginal knowledge-holders on Cape York Peninsula to openly share and discuss historical truths around colonial violence and disposession—while highlighting the strength and resilience of First Peoples (ANTaR 2024)—the project team hope to correct historical omissions that have stood for more than 150 years and provide a more complete picture of the way in which colonial plant collections were made. Initial engagement is being undertaken with Aboriginal communities in Cape York will be undertaken to generate shared history-making and elevate Indigenous knowledge and memory to develop countervailing historical narratives and recontextualise the botanical specimens collected on the expedition. All engagement with Aboriginal communities will be held on-Country, i.e., on lands to which the Aboriginal peoples being consulted are connected via law, cultural practice, spiritual belief, language and/or custom (AIATSIS 2024). At the time of writing, the three descendants are continuing a series of region-specific engagements that are generating interest in—and support for—Indigenous-led knowledge-sharing and the documentation of untold stories. Based on this initial show of support, the project partners will likely seek funding for a broader Indigenous-led program of on-Country truth- and storytelling around key events that followed the 1872 Hann Expedition. Alongside the on-Country truth-telling, the project will help herbaria develop protocols for recording Indigenous Cultural Knowledge (ICK) shared by Aboriginal knowledge-holders in ways that uphold cultural safety and principles of Indigenous Data Sovereignty and Data Governance. Through two-way knowledge sharing, we hope to enrich the specimens both culturally and scientifically by: acknowledging the histories of specimens and the Traditional Owners of the lands on which they were collected; accommodating ethnobotanical enrichment of specimens by recording ICK alongside Western scientific knowledge in collection management systems, if requested by Traditional Owners; and connecting specimens to Country via enhanced georeferencing utilising Aboriginal knowledge of plants and place, and Expedition resources. acknowledging the histories of specimens and the Traditional Owners of the lands on which they were collected; accommodating ethnobotanical enrichment of specimens by recording ICK alongside Western scientific knowledge in collection management systems, if requested by Traditional Owners; and connecting specimens to Country via enhanced georeferencing utilising Aboriginal knowledge of plants and place, and Expedition resources. This symbiotic blending of botanical science and Indigenous Cultural Knowledge will 'give voice to Country' through knowledge partnerships, helping to heal the past, and to better understand and conserve the complex biodiversity of Cape York.

Cultivating Environmental Ignorance: Non-Circulation of Ethnomedicinal Knowledge about Culén (Otholobium glandulosum) in the Atlantic World (1646–1810)

A growing body of literature recognises the importance of exploring the uses of plants in historical written sources. The Chilean native plant culén (Otholobium glandulosum) has a long history of medicinal use, with various parts of the plant, including its leaves, aerial parts, and roots, employed to treat numerous ailments. This study undertakes a Critical Discourse Analysis of historical sources, specifically books published between the 17th and early 19th centuries (1646–1810), focusing on the medicinal applications of culén. The research highlights the circulation of plant knowledge over time by adopting an interdisciplinary approach that bridges historical ethnobotany, environmental history, and the history of knowledge and ignorance studies. The study reveals how the evolution of the ethnobotanical and ethnomedicinal knowledge of culén reflects the broader environmental ignorance, wherein the scientific community excluded and oppressed the indigenous and local knowledge of the plant. This work underscores the importance of integrating historical studies into modern environmental and botanical research, emphasising the value of understanding past knowledge systems to inform contemporary conservation efforts and sustainable practices.

Ethnomedical knowledge of plants used in alternative medicine to treat hemorrhoidal diseases in Lubumbashi, Haut-Katanga province, Southern Democratic Republic of Congo

BackgroundA variety of medicinal plants are used in traditional medicine in Lubumbashi for the management of hemorrhoidal diseases. However, no investigation has been conducted to gather the knowledge required for this type of management in the region. The present study was conducted to inventory the plants used in Lubumbashi to treat hemorrhoidal diseases and to relate their ethnomedical characteristics.MethodsThis study was conducted between March 2022 and February 2023 by interviews using semi-structured questionnaire with households (n = 1520), herbalists (n = 25), and traditional healers: THs (n = 59).ResultsThe 1,604 respondents (sex ratio M/F = 0.9; mean age: 56 ± 3 years; experience: 12 ± 3 years) provided information on 100 taxa, 84 of which are used against internal hemorrhoids, Phyllanthus amarus being the most cited (Citation Index, CI: 0.76). Most of them are trees (38%) or shrubs (32%), belonging to 90 genera and 45 families dominated by the Fabaceae (10%) and Asteraceae (9%). They are indicated in 76 other pathologies, dominated by gastrointestinal disorders (GID), wounds and sexually transmitted infections (CI > 0.57). From these 100 taxa, 117 anti-hemorrhoidal formulations were derived, 11 of which combined more than one plant. In all these recipes, the leaf is the most commonly used part (> 60%) and the liniment (> 45%) is the most popular form of application. For the first time, this study reports 14 taxa as plants used in the treatment of hemorrhoids. Among these taxa, Ficus stuhlmannii, Ficus laurifolia, and Ocimum centraliafricanum are listed as medicinal plants for the first time. Khaya nyasica, and Syzygium cordatum, each with 11 uses, have the highest traditional medicinal value.ConclusionThe findings of this study indicate that a significant number of medicinal plants are used in traditional medicine in Lubumbashi for the treatment of hemorrhoidal diseases. Some of these plants are endemic to the biodiversity area, while others are shared with other cultures and regions. A series of pharmacological studies is currently underway with the objective of validating the anti-hemorrhoidal properties of these plants and in order to identify phytochemical compounds responsible of this activity.Graphical

Wild-grown medicinal plants used by the Asháninka people from the Tambo River, Peruvian Amazonia

Ethnopharmacological relevanceThe Asháninka people are the largest Peruvian Amazonian group, yet the knowledge of their medicinal plants is scarce. This study on Asháninka herbal medicine offers an insight into the Asháninka aetiological system, resting within the wider ontological framework of animism, and cultural expressions of the biomedical understanding of illnesses. Aim of the studyTo document wild-grown (non-cultivated) plant species in current use by the Asháninka people and look closer at their herbal practices during the Covid-19 pandemic. The study examines whether the knowledge and use of medicinal plants is gendered in this society. It also compares the findings with available literature concerning the Arawakan groups from Peruvian Amazonia. Material and methodsThe fieldwork was conducted in 13 native communities of the Asháninka people along the Tambo River (Selva Central), Peru, between 2016 and 2018 and in 2022. The main field technique were guided walks in the forest with 27 female and 28 male participants, during which voucher specimens were collected and relevant information was recorded. Semi-structured interviews were performed with specialists in Asháninka traditional medicine and with lay Asháninka people to better understand Asháninka illness aetiologies. The analysis of medicinal plants included medicinal categories and uses, modes of preparations, the frequency of use and the knowledge about the plants between the genders. It also presents and discusses detailed testimonies of herbal remedies during the Covid-19 pandemic. The list of recorded plants was compared with ethnobotanical studies of other Arawakan groups from Peruvian Amazonia. ResultsAltogether, 169 wild-grown medicinal plant species were documented. Our findings highlight the importance of the Piperaceae and Acanthaceae botanical families in the Asháninka pharmacopoeia. The plants were used for 23 medicinal categories, of which dermatological disorders, digestive problems and venomous bites were the most prevalent. Over 70% of recorded plants were commonly and moderately known by the study participants. More exclusive species were found among the men than women; however, 64 % of all recorded plants were known to both genders. Sixty-one percent of recorded plants were not mentioned by any other study of medicinal plants among other Arawakan groups in Peruvian Amazonia. During the Covid-19 pandemic, nobody in the native communities at the Tambo River died directly due to the virus, which was attributed, amongst others, to effective and culturally-appropriate prophylaxis and treatments with medicinal plants. ConclusionTo this day, the Asháninka people at the Tambo River conserve the knowledge and practices related to medicinal plants which meet the daily needs of dwelling in subtropical forest; these are deeply rooted in animistic ontology, with the emphasis on spirit predation and retaliation. And yet, numerous applications of plants are compatible with the biomedical notion of illness and symptoms. Plant knowledge is shared between the genders, although specific plants exist for men and women, which are related to their gendered social and family roles. Some overlap and consensus exists with other studies regarding medicinal uses, which reflects the rich and diverse knowledge of medicinal plants among the Arawakan groups in Peruvian Amazonia, and this deserves further study.

Utilizing drawings to understand how our backgrounds and experiences change our plant mental models

Societal Impact StatementOur culture, life experiences, and the places we live teach us about the world around us and the plants within it. This information gives each individual distinct mental models. By delving into plant mental models of young adults, this study offers insights into the complex landscape of plant knowledge, with a special emphasis on Indigenous communities. Beyond broadening our understanding, these findings provide valuable resources for educators and researchers striving to bridge the gap in plant literacy. Moreover, the methods used offer a blueprint for similar investigations globally, which will foster a deeper understanding of plant awareness across diverse populations.Summary Plant mental models, or what people think about when they think of a given plant, give insight into a person's knowledge and understanding of plants. However, little to no research has been conducted on plant mental models of young adults or comparing mental models across demographics. This study assessed college students' plant mental models in the demographic categories of race, gender, rurality, and college type (tribal vs. non‐tribal), as well as experience in art, photography, and plant identification, to determine the impact of these factors on plant mental models. A total of 697 students from three tribal and three non‐tribal colleges enrolled in a specific introductory biology course participated. Participants completed four drawings, which represented their mental model of a plant, flower, grass, and tree. They also completed a short survey about demographics and experience with art, photography, and plant identification. Tree drawings had the most detail, and grass drawings had the least. Gender was the only demographic factor that impacted the detail drawn, with females including more detail for flowers and trees and males for grass. Surprisingly, experience with art, photography, and plant identification did not impact the detail included in the drawings. Overall, participants plant mental models across demographics were simplistic and lacked detail, potentially indicating a lack of plant awareness.

Composition, medicinal values, and threats of plants used in indigenous medicine in Jawi District, Ethiopia: implications for conservation and sustainable use

Indigenous knowledge of medicinal plants is vital to local communities and cultural heritage, particularly in Ethiopia. This study aims to document native medicinal plants in the Jawi district, including associated traditional knowledge. The study involved conducting semi-structured interviews, focus group discussions, and guided field walks with a purposefully selected 54 traditional healers. The study identified 87 medicinal plant species from 50 families used treat over 50 ailments, with a preference for wild herbs. Fabaceae, Malvaceae, and Solanaceae were the most prominent families, each with five species; Zehneria scabra, was the most often mentioned species, followed by Lepidium sativum, Myrica salicifolia, Carissa spinarum, and Momordica foetida. 43% of identified species were herbs, with 44% of remedies made from roots. Pounding was the most common preparation method, and oral application was the most frequent use, followed by dermal application. 60% plants treated human ailments, 16% treated livestock, and 24% were used for both. Preference rankings indicated specific plants favored for certain ailments. The study highlights key plant families and species crucial for local healthcare but notes threats like habitat destruction and knowledge loss. Urgent conservation actions are needed to preserve medicinal plants and inform future research and strategies.

What Are the Phylogenetic Limits to Pollinator Diversity?

ABSTRACTAlthough huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and what are the phylogenetic limits to that diversity? Which other groups of animals, not currently known to regularly engage with flowers, might be found to be pollinators in the future? Can we predict, from the fossil record and from discoveries in under‐researched parts of the world, which animal groups might turn out in the future to contain pollinators? I also discuss why adding to our knowledge of plant–pollinator interactions is important, but also stress that an incomplete knowledge may not be a bad thing if it means that remote, inaccessible and relatively pristine parts of the world remain that way.

Ethnobotanical study of wild edible plants in the mountainous regions of Semnan Province, Iran

In mountainous areas, wild edible plants are an important part of the local diet. Climate change and anthropogenic activities have profound effects on wild edible plants in these areas. Ethnobotanical studies are important for understanding the use patterns and harvest impacts on these plants. In this regard, the Shahrood region, with its diverse historical/ethnic background, is an appropriate starting point to investigate exploitation patterns and impacts of harvest of wild edible plants. During 2021–2022, ethnobotanical surveys were conducted in 12 villages in the region using semi-structured interviews and participatory observations. Data collection included assessing wild edible plant species diversity, their habitats, collection time and quantities, plant parts used and methods of consumption and preparation. The data were analyzed using use report indicators, relative frequency of citations, and use value (UV). A total of 1086 use reports were documented from a total of 44 interviews. A total of 67 wild species (66 plants and 1 fungus) belonging to 54 genera and 24 families were used as edible in the study area. Rosaceae (9 species), Apiaceae (8), Lamiaceae (8), Asteraceae (7), and Amaryllidaceae (5) were the families with the most reported species. Allium (5 species) was the most diverse genus in terms of species diversity. Herbs were the most commonly used life form (79.1%), followed by shrubs (13.4%) and trees (6%). The most consumed plant parts were young leaves (25%) and young aerial parts (21.4%). There were 13 use categories identified. The majority of edible plants were collected in April–May, mainly from areas nearby villages (37.7%) and rangelands (33.7%). The most important edible plants in the study area were Allium iranicum (Wendelbo) Wendelbo (UV = 1.7), Mentha longifolia (L.) Huds. (1.5), Allium umbilicatum Boiss. (1.47), Tragopogon graminifolius DC. (1.38), Lepidium draba L. (1.27), Urtica dioica L. (1.18), Falcaria vulgaris Bernh. (1.13), Malva neglecta Wallr. (1.11) and Eremurus sp. (1.09). Our results showed diverse and valuable knowledge for wild edible plants in this region, which should be considered in the conservation and management plans in the region.

Women's Knowledge of Local Plants and Their Gastronomic Heritage in Chitral, NW Pakistan.

Women are the "guardians of the kitchen" and central to household food security, yet their role has never been studied across the Hindukush region or Pamiri Knot. This study explores the women's knowledge (specifically from the Khowar (Kho) and Wakhi linguistic groups) of local food systems and determines their role in ensuring household food security and sustainability in the mountain regions of northern Pakistan. Based on in-depth semi-structured interviews with female informants in the Rech and Broghil valleys of upper Chitral, 91 different types of food products were recorded, including wild and cultivated species. Eremurus stenophyllus and Allium barsczewskii were the commonly utilized plant species, though distinct preferences between the Kho and Wakhi groups were noted. Prominent differences were perceived in using certain cultivated plants among the two ethnic groups. For instance, Kho preferred plants like Beta vulgaris, Zea mays, and Brassica napus as indicated by the use reports, while Wakhi concentrated on Thymus serpyllum, Zygophyllum obliquum and Papaver involucratum. Both groups had shared dairy practices, but cottage cheese and curd were highly cited among Kho, while double-fermented curd and Qurut for Wakhi. The study recorded some new food uses for specific plants, such as Atriplex hortensis, Carthamus tinctorius, Hylotelephium spp., and Saxifraga sibirica. Cross-culture analyses revealed a mosaic pattern of homogenous and heterogenous trends based on reported food species of plants/animals and their use reports. Our findings emphasize the significant role of women in sustaining local food diversity, food sustainability, and the preservation and security of the local food systems, cultural legacy, and household food management. Therefore, inclusive research addressing their social, economic, and environmental issues must be conducted. Furthermore, policies must incorporate women's traditional knowledge to build resilient food systems.

This study discusses the use of traditional medicinal plants from an ethnopedagogical perspective, focusing on a case study in the Sundanese community. The research aims to understand the traditional healing practices involving the use of medicinal plants among the Sundanese people and how the ethnopedagogical approach can be used to uncover local knowledge and strengthen these cultural practices. The research methodology employed is a qualitative approach with data collection techniques through participatory observation, in-depth interviews, and documentation study. The research sample was purposively selected, involving community leaders or traditional healing experts with extensive knowledge of medicinal plants and traditional healing practices in the Sundanese community. The results show that the use of traditional medicinal plants remains an integral part of the Sundanese healthcare system. These plants are used to treat various diseases and health disorders, serving as symbols of local wisdom and cultural identity. The ethnopedagogical approach facilitates the sustainable transfer of knowledge from generation to generation and raises awareness of the importance of preserving cultural heritage in the context of traditional medicine.

The 2030 Declaration on Scientific Plant and Fungal Collecting

Societal Impact StatementBiological samples and their associated information are an essential resource used by scientists, governments, policymakers, practitioners and communities to ensure that biodiversity can be appropriately protected and sustainably used. Yet, considering the enormous task of documenting the vast numbers of as‐yet‐unknown plant and fungal species, greater international coordination for biological collecting and recording is necessary, built on equitable collecting practices and standards. Here, we propose five commitments to accelerate and enhance scientific knowledge of plant and fungal diversity, while increasing collaboration, benefit sharing and efficiency.SummaryAlmost all life depends on plants and fungi, making knowledge of their diversity and distribution—primarily derived from biological collections—fundamental to national and international conservation, restoration and sustainable use commitments. However, it is estimated that some 15% of all plant species and over 90% of all fungal species have not yet been scientifically described, hampering our ability to assess and demonstrate the impact of efforts to halt biodiversity loss. In addition, organisations and researchers around the world lack a concerted strategy for increasing complementarity and avoiding overlap in botanical and mycological research, particularly in relation to the collection of specimens. We here present the 2030 Declaration on Scientific Plant and Fungal Collecting, summarising a commitment towards such a necessary strategy. Its components were identified from discussions during and after a series of four workshops and plenary discussions at the 2023 State of the World's Plants and Fungi symposium convened by the Royal Botanic Gardens, Kew, and were then consolidated into the present form by the authors. The Declaration was subsequently opened up for endorsement by signatories. Collectively, we agree on a set of five commitments for cataloguing the world's flora and funga, designed to maximise efficiency, facilitate knowledge exchange and promote equitable collaborations: (1) use evidence‐based collection strategies; (2) strengthen local capacity; (3) collaborate across taxa and disciplines; (4) collect for the future; and (5) share the benefits. This Declaration is a first step towards increased global and regional coordination of scientific collecting efforts.

Indigenous Knowledge and Herbal Medicine: Exploring the Ethnobotany of the Karo Tiganderket Tribe in Indonesia

This ethnobotanical study investigates the traditional use of medicinal plants in Tiganderket Village, Karo Regency, Indonesia, to document local plants' diversity, uses, and preparation methods for medicinal purposes. Utilizing a quantitative descriptive approach, data were gathered from 30 informants, including traditional healers and residents. The study identified 92 plant species from 44 families, with the Zingiberaceae family being the most dominant. Frequently used plants, such as Piper betle (belo) and Zingiber officinale (ginger), were primarily employed to treat common ailments like fever, boils, and joint pain. Boiling (74%) was the most common method of plant preparation, and leaves (50%) were the most frequently used plant parts. The Relative Frequency of Citation (RFC) revealed Acorus calamus and Curcuma longa as the most cited species. At the same time, 40 of 66 recorded diseases showed high Informant Consensus Factor (ICF) values, reflecting shared knowledge of plant use. This study highlights the rich preservation of traditional medicinal plant knowledge in Tiganderket Village, which continues to play a crucial role in local healthcare practices.

Ethnobotanical knowledge of plant species of the North-East of Morocco, with three provinces as a case study: Al Hoceima, Nador, and Jerada.

This study focuses on taxa found in the Northeastern part of Morocco and cited in the book “Al Jam’ li-Mufradat al-Adwiya wa’l-Aghdiya (The Book of Simple Drugs) by Ibn Al Baytar. The main objective of this study is to determine whether the taxa on our list are recognized by the populations in the three provinces of Northeastern Morocco, as well as to collect information about their traditional uses (medicinal or non-medicinal), their modes of preparation and administration, the plant parts used. All the data have been collected through conducting an open-ended, semi-structured interviews with randomly selected individuals. The informant consensus factor (FIC) was calculated to identify the level of agreement among informants regarding the use of medicinal plants for specific disease groups. During these ethnobotanical surveys, 1,177 persons were interviewed. We were able to record a total of 241 taxa belonging to 66 families with 1,264 uses mentioned in the three provinces. The results obtained confront us with the idea that there is a decline of autochthonous knowledge. They reveal that 32.12% of the local population considers itself ignorant of the uses of plants to cure illness, and that 66.78% prefer modern medicine despite possessing some knowledge of traditional medicinal plants. However, 790 medicinal uses recorded were classified according to the WHO’s international Classification of diseases (ICPC-2, International Classification of Primary Care), and 474 other uses were recorded, along with the transcription of new vernacular names for 107 taxa. This confirms the importance of ethnobotanical studies as it plays an important role in preserving the reservoir of indigenous knowledge from being lost over time.

Ethnobotanical, ethnopharmacological, socioeconomic and floristic studies of aromatic and medicinal plants from Boulemane region in Morocco

These studies were conducted to uncover the potential and traditional knowledge of aromatic and medicinal plants (AMP) in the Boulemane province of the Middle Atlas, an area previously unexplored. The objectives were to inventory and identify AMP used in the region’s traditional medicine, gather extensive information from locals and professionals on their usage and exploitation, and identify the most promising species for further studies, to be highlighted in future publications. The floristic study enabled the identification of 71 families out of 155 existing in Morocco, comprising 313 genera and 618 species and subspecies, which represent 11% of the global Moroccan floristic richness. Additionally, 84 taxa from 20 families are endemic with 78% being exclusive to Morocco. The ethnopharmacological study revealed that 88.47% of the informants use AMP for therapeutic purposes in 58.21% of the cases. A catalog of traditional practices was compiled, documenting 79 species across 38 families. Rosemary, sagebrush, pennyroyal, thyme, berber cedar, lavender sage, and clubroot were the most frequently cited species, mainly used to treat stomach and respiratory problems. However, only 17.6% of the population exploits this wealth through the creation of cooperatives and/or associations. This study assessed the role of AMP in fostering sustainable development in the region. The evaluation was based on a series of studies, with particular emphasis on the ethnopharmacological aspect. The latter has facilitated the promotion of awareness of sustainable usage practices and the training of professionals to implement these practices while ensuring the conservation of botanical resources against over-exploitation.

Can family structure and contact with natural resources influence young people’s knowledge about medicinal plants? An approach in the Northeast of Brazil

BackgroundIndividuals develop crucial survival knowledge in the juvenile phase, including understanding medicinal plants. The family context or contact with resources can influence this dynamic knowledge. By investigating the influence of these factors on young people's understanding of medicinal plants, we aimed to enhance our understanding of the knowledge-building process.MethodsThe study was conducted in three communities in the State of Alagoas, Brazil: Lagoa do Junco, Serrote do Amparo, and Brivaldo de Medeiros. Semi-structured interviews were conducted with young people aged between 11 and 19 to assess their knowledge of medicinal plants. We used a generalized linear mixed model (GLMM) with the number of therapeutic targets and known medicinal species (knowledge proxy) as response variables. As predictors, we included the number of individuals per family unit and the gender distribution within the famimunícpily (family context proxy), as well as dependence on the use (contact proxy). Location (city) was added as a fixed effect to the model. We investigated how knowledge of medicinal plants correlates with the practice of collecting these species.ResultsWe did not identify a relationship between the number of individuals per household, gender distribution within the family, and the frequency of medicinal plant use with knowledge about these species. However, we observed a positive, albeit weak, correlation between knowledge of medicinal species and the number of species collected.ConclusionThese results highlight the importance of investigating how young people acquire knowledge about medicinal plants, emphasizing the complex interactions between humans and nature, and providing a basis for future research.

Medicinal plants diversity among the oromo community in heban-arsi district of Ethiopia used to manage human and livestock ailments.

Medicinal plants are commonly employed mainly due their accessibility, affordability and potency. However, medicinal plants and the associated knowledge are disappearing at an alarming rate due to natural and anthropogenic causes and thus a need for their proper documentation conservation. This study was performed to document traditional knowledge related to use of medicinal plants in Heban-Arsi district, West-Arsi Zone, Oromia Regional State, Ethiopia. Interviews were conducted with 185 informants to identify medicinal plants used in traditional therapies in the study area. Informant consensus factor (ICF), rank order priority (ROP) values were computed, and preference ranking exercises were performed to assess the relative importance of medicinal plants. Descriptive and inferential statistics were used to measure and compare medicinal plants knowledge between social groups. A total of 120 medicinal plants were identified for being used to treat different human and animal illnesses in the study area. Most of the medicinal plants (76.4%) were uncultivated ones obtained from different habitats. Leaf was the most frequently used plant part constituting 62.6% of preparations. Oral was the most commonly used route of remedy administration (46%) in treating diseases. Gastrointestinal ailments category had the highest ICF value (0.83). In the study area, the highest rank order priority (ROP) values were recorded for Dombeya torrida (J.F. Gmel.), Artemisia absinthium L., Balanites aegyptiaca (L.) Del., Combretum pisoniiflorum Klotzsch) Engl., Celtis africana Burm. f, Ocimum gratissimum L. and Lagenaria sp. for their uses against snake poison, tuberculosis, liver disorder, stomachache, tuberculosis, febrile illness and liver disorder, respectively, each scoring a value of 100. Significant differences in medicinal plant use knowledge were recorded between male and female informants of different educational level, age and experience. Anthropogenic factors were the primary threats to medicinal plants in the area. The study area was found to be rich in medicinal plants that are useful in treating a wide range of human and animal illnesses. In future pharmacological and phytochemical investigations, priority needs to be given to medicinal plants of the highest ROP values and those that were reported against ailment categories scoring the highest ICF values.
