Ethnobotanical inventory of medicinal plants used by Cashinahua (Huni Kuin) herbalists in Purus Province, Peruvian Amazon.

This study aims to document the diversity of medicinal plants used by the Cashinahua people (also known as Huni Kuin) of the Curanja River, as well as describe and compare their uses with pharmacological and phytochemical records from previously published studies. The ethnic has been studied to a limited extent from an ethnobotanical perspective. The study area is located in the Ucayali region, eastern Central Amazon, where ancestral knowledge is preserved due to the limited accessibility of the region. Between November 2010 and June 2015, a total of 11 months were spent on the survey, which included a short-term visit to complete voucher specimen collection and taxonomic identification. We conducted semi-structured interviews with 10 Cashinahua traditional healers and 10 midwives. Vernacular names, ethnomedicinal uses, plant parts used and forms of preparation and administration were recorded. Ethnopharmacological, pharmacological and phytochemical uses were checked through survey of the previously published papers indexed on Web of Science databases between 2018 and 2022. We obtained data on 467 plant taxa, among which we highlighted 79 species unreported or rarely cited for medicinal use or phytochemical analysis. These species were spread over 60 genera and 42 botanical families, with Acanthaceae being the most represented. Leaves were used the most frequently (93.56%). Among the 79 species, the most reported therapeutic activities involved pregnancy and birth disorders (13.84%), followed by poisonings, infections and infestations. The predominant application form was external (87%). Our study indicates that there are locally valuable species that have not yet been studied for their medical potential.

From Sxex to Chorta: The Adaptation of Maronite Foraging Customs to the Greek Ones in Kormakitis, Northern Cyprus.

The traditional foraging of wild vegetables (WVs) has played an important role in the post-Neolithic development of rural local food systems of the Near East and the Mediterranean. This study assessed the WVs gathered by the ancient Maronite Arabic diaspora of Kurmajit/Kormakitis village in Northern Cyprus and compared them with those gathered by their Cypriot and Arab Levantine neighbors. An ethnobotanical field survey focusing on WVs was conducted via twenty-two semi-structured interviews among the few remaining Maronite elderly inhabitants (approximately 200); and the resulting data were compared with those described in a few field studies previously conducted in Cyprus, Lebanon, and coastal Syria. Wild vegetables in Kormakitis are grouped into a folk category expressed by the emic lexeme Sxex, which roughly corresponds to the Greek concept of Chorta (wild greens). The large majority of Sxex have Greek folk phytonyms and they overlap for the most part with the WVs previously reported to be gathered by Greek Cypriots, although a remarkable number of WVs are also shared with that of the other groups. The findings address a possible adaptation of Maronite WV foraging to the Greek one, which may be explained by the fact that the Maronite minority and the majority Greek communities lived side by side for many centuries. Additionally, after Turkish occupation in 1974, a remarkable migration/urbanization of Maronites to the main Greek centers on the southern side of the isle took place, and Kurmajit became part of Cypriot trans-border family networks.

The nexus between traditional foraging and its sustainability: a qualitative assessment among a few selected Eurasian case studies.

Plant foraging is an important human ecological phenomenon being studied by a number of contemporary ethnobiologists as well as by a few social anthropologists among rural communities and, more recently, in urban environments. The sustainability dimension of foraging is, however, largely unexplored. We analyse a few case studies from recent field research and qualitatively assess both the environmental and social sustainability of diverse patterns of traditional foraging practices in three distinct human ecological environments (horticulturalism-, forestry-, and pastoralism-driven) located in the Eastern Mediterranean, Eastern Europe, and North Pakistan, i.e. we address the question of when does traditional foraging become unsustainable and what factors may influence this. The main findings are multidimensional. First, in all case studies, we sometimes observed competitive foraging among the gatherers of certain wild food plants potentially causing ecological degradation; such unsustainable practices seem to be linked to the market pressure on certain species. However, also customs and norms promoted by states can be detrimental (former Soviet Union), as well as climate change (Eastern Europe), and marginalisation of some minority groups (Pakistan). Second, in the Mediterranean Syrian context, wild food plant resources are largely represented by widely available weedy "wild" vegetables, normally (but not exclusively) collected by women, and usually easily accessible; only very few wild food plants seem to be threatened due to specific market demands or to disequilibria created by household economic instabilities due to the recent war. We also argue that unsustainable foraging is enhanced by the abandonment of daily practices and continuous interaction with the natural environment and by the increasingly uneven distribution of active practical knowledge on wild food plants among the middle-aged and younger population. Facilitating the transmission of sustainable foraging knowledge and practices could be therefore crucial, also for coping with food insecurity in times of crisis; but for that to occur, holistic environmental and food educational frameworks, appropriate policies for fostering community-based biodiversity conservation and also social cohesion and communal management of lands should be seriously considered as well. Moreover, future gastronomic and eco-tourism initiatives, if organised in a thoughtful manner, could represent a positive turning point not only for the local small-scale economies of the considered rural communities but also for helping them to dynamically preserve the entire socio-ecological system underpinned in plant foraging and ultimately to better adapt to the current global crisis.

Food Behavior in Emergency Time: Wild Plant Use for Human Nutrition during the Conflict in Syria.

Wild food plants (WFPs) have been an important source of human nutrition since ancient times, and it particularly revives when conventional food is not available due to emergency situations, such as natural disasters and conflicts. The war in Syria has entered 10 years since it started in 2011, and it has caused the largest war-related crises since World War II. Nearly 60% of the Syrian population (12.4 million people) are food-insecure. WFPs are already culturally important in the region, and may be supplementing local diets during this conflict. Our study aimed to uncover the conflict's effect on the use of WFPs and to know what species are consumed by local people during the current crisis. The fieldwork was carried out between March 2020 and March 2021 in the Tartus governorate located in the coastal region of Syria. Semi-structured interviews were conducted with 50 participants (26 women and 24 men) distributed in 26 villages along the study area. We recorded the vernacular names, uses, plant parts used, modes of preparation and consumption, change in WFP use before and during the conflict, and informants' perceptions towards WFPs. We documented 75 wild food plant species used for food and drink. Almost two-thirds (64%) of informants reported an increase in their reliance on wild plants as a food source during the conflict. The species of Origanum syriacum, Rhus coriaria, Eryngium creticum, and Cichorium intybus were among the most quoted species by informants. Sleeq (steamed leafy vegetables), Zaatar (breakfast/dinner food), and Louf (soup) were the most popular wild plant-based dishes.

Socio-Cultural Significance of Yerba Maté among Syrian Residents and Diaspora.

Socio-Cultural Significance of Yerba Maté among Syrian Residents and Diaspora. Syria is the world's second-largest importer of the dried leaves of Ilex paraguariensis A.St.-Hil., commonly known as yerba maté. The unique story of yerba maté in the Syrian beverage culture started at the beginning of the twentieth century when Syrian migrants returning from South America brought the beverage with them. The overall aim of our study is to understand yerba maté use among Syrians and its role as an essential part of the Syrian beverage culture. We compare yerba maté consumption on spatial, gender, and religious bases through semi-structured interviews with 50 respondents, with equal participation among genders, place of residence, and cultural-religious groups (Sunni, Alawite, Christian, Druze, and Ismaili). We found that the Alawite and Druze groups have the highest yerba maté consumption, and that men drink more than women. Yerba maté was the most preferred stimulant drink among participants, followed by coffee and tea, respectively. Interviews reveal social and cultural factors, perceived addiction, perceived pleasure, and perceived health properties as the drivers behind yerba maté consumption in Syria.

The Chemical Composition of Oils and Cakes of Ochna serrulata (Ochnaceae) and Other Underutilized Traditional Oil Trees from Western Zambia.

Currently, the negative effects of unified and intensive agriculture are of growing concern. To mitigate them, the possibilities of using local but nowadays underused crop for food production should be more thoroughly investigated and promoted. The soybean is the major crop cultivated for vegetable oil production in Zambia, while the oil production from local oil-bearing plants is neglected. The chemical composition of oils and cakes of a three traditional oil plant used by descendants of the Lozi people for cooking were investigated. Parinari curatellifolia and Schinziophyton rautanenii oils were chiefly composed of α-eleostearic (28.58-55.96%), linoleic (9.78-40.18%), and oleic acid (15.26-24.07%), whereas Ochna serrulata contained mainly palmitic (35.62-37.31%), oleic (37.31-46.80%), and linoleic acid (10.61-18.66%); the oil yield was high (39-71%). S. rautanenii and O. serrulata oils were rich in γ-tocopherol (3236.18 µg/g, 361.11 µg/g, respectively). The O. serrulata oil also had a very distinctive aroma predominantly composed of p-cymene (52.26%), m-xylene (9.63%), γ-terpinene (9.07%), o-xylene (7.97), and limonene (7.23%). The cakes remaining after oil extraction are a good source of essential minerals, being rich in N, P, S, K, Ca, and Mg. These plants have the potential to be introduced for use in the food, technical, or pharmaceutical industries.

Wild Food Plants and Trends in Their Use: From Knowledge and Perceptions to Drivers of Change in West Sumatra, Indonesia.

Wild food plants (WFPs) are often highly nutritious but under-consumed at the same time. This study aimed to document the diversity of WFPs, and assess perceptions, attitudes, and drivers of change in their consumption among Minangkabau and Mandailing women farmers in West Sumatra. We applied a mixed-method approach consisting of interviews with 200 women and focus group discussions with 68 participants. The study documented 106 WFPs (85 species), and Minangkabau were found to steward richer traditional knowledge than Mandailing. Although both communities perceived WFPs positively, consumption has declined over the last generation. The main reasons perceived by respondents were due to the decreased availability of WFPs and changes in lifestyle. The contemporary barriers to consuming WFPs were low availability, time constraints, and a limited knowledge of their nutritional value. The key motivations for their use were that they are free and "unpolluted" natural foods. The main drivers of change were socio-economic factors and changes in agriculture and markets. However, the persistence of a strong culture appears to slow dietary changes. The communities, government and NGOs should work together to optimize the use of this food biodiversity in a sustainable way. This integrated approach could improve nutrition while conserving biological and cultural diversity.

Medicinal plants used by 'root doctors', local traditional healers in Bié province, Angola.

ETHNOPHARMACOLOGICAL RELEVANCE: This study is one of the first post-civil war efforts to document traditional botanical knowledge in Bié province, central Angola, in a first step to bring more studies on the use of medicinal plant resources in this area so as to bring new insights into Angolan bio-cultural diversity. AIM OF THE STUDY: Examine the variety of plant species used for medical purposes, as well as characterize their social and cultural values. Also, it is aimed to compare their uses in the studied region with those in Sub-Saharan Africa and report new ethnomedicinal uses. MATERIALS AND METHODS: We documented traditional medicinal plant knowledge among professional herbalists in two areas in Bié province through participatory observation, semi-structured interviews and transect walks. Ethnobotanical information was quantified based on Use Reports to (1) rate traditional knowledge; and (2) determine most useful taxa. RESULTS: In total, 10 traditional healers shared information on their knowledge. A total of 87 plant species distributed among 57 genera and 36 botanical families were documented with Fabaceae being the best-represented family with 18 species, followed by Phyllanthaceae (6), Apocynaceae (5), Asteraceae (5), Rubiaceae (5), Lamiaceae (4), and Ochnaceae (3). Most medicinal plants are usually gathered at a distance from human settlements because of the belief in the higher efficacy of 'wild' plants shared by all herbalists. Roots are the most common plant part used (79%), explaining why the consulted herbalists call themselves 'root doctors'. CONCLUSIONS: The culturally most important medicinal species identified in this study, i.e. Securidaca longepedunculata, Garcinia huillensis, Annona stenophylla, Afzelia quanzensis and Strychnos cocculoides, were previously reported for the same use in neighbouring countries and elsewhere in Africa. Our study also indicates that there are several locally valuable species that have not yet been studied for their medical potential, to name a few: Alvesia rosmarinifolia, Diplorhynchus condylocarpon, Eriosema affine, Paropsia brazzaeana, Rhus squalida, Sclerocroton cornutus or Xylopia tomentosa. Moreover, the ethnomedicinal use of 26 species was reported for the first time to sub-Saharan Africa. CLASSIFICATION: Ethnopharmacological field studies.

Beetles, ants, wasps, or flies? An ethnobiological study of edible insects among the Awajún Amerindians in Amazonas, Peru.

BACKGROUND: Insects are known to be able to provide valuable nutrients to indigenous populations across the Amazon. However, studies on traditional insect use in the Peruvian Amazon are scarce. This study documents edible insect diversity and characterizes their food and collection patterns in eight Awajún communities in the Peruvian Amazon. Additionally, we reviewed what has been known to date about the nutrient composition of the documented species. METHODS: The survey was conducted among the Awajún populations living in the Huampami, Paisa, Achu, and Tseasim communities in the Cenepa district and the Shijap, San Mateo, Kusu, and Listra communities in the Imaza district. Data collection was conducted through a freelisting exercise complemented by a semi-structured inquiry form in the Awajún language. In total, 104 informants (72 men and 32 women) aged between 16 to 73 years were interviewed. RESULTS: The Awajún people use at least 12 insect species, with Rhynchophorus palmarum, Atta cephalotes, and Rhinostomus barbirostris being the most important ones. Beetles of the family Curculionidae represent the culturally most salient taxon. In the more accessible and developed Imaza district, the Awajún tend to eat almost exclusively R. palmarum, while in the more isolated and preserved Cenepa district, the community's preferences are linked with more species. Although men are the main insect collectors, women cited more edible insects on average. The insects are eaten mainly roasted or raw. Further use patterns and differences between the districts are discussed. CONCLUSION: Traditional knowledge related to edible insects and the ecosystems they occur in is widespread among the Awajún populations, and insects still represent an important part of the indigenous food system. This ethnobiological survey discovered five species that are newly recorded as edible insects. Chemical composition of insects deemed edible by the Awajún ought to be analyzed in the future and awareness about their nutritional importance should be raised to harness the potential of this underutilized yet nutrient-rich traditional food.
