Comparative phylogenetic methods and the cultural evolution of medicinal plant use
Human life depends on plant biodiversity and the ways in which plants are used are culturally determined. Whilst anthropologists have used phylogenetic comparative methods (PCMs) to gain an increasingly sophisticated understanding of the evolution of political, religious, social, and material culture, plant use has been almost entirely neglected. Medicinal plants are of special interest because of their role in maintaining people’s health across the world. PCMs in particular, and cultural evolutionary theory in general, provide a framework in which to study the diversity of medicinal plant applications cross-culturally, and to infer changes in plant use through time. These methods can be applied to single medicinal plants as well as the entire set of plants used by a culture for medicine, and they account for the non-independence of data when testing for floristic, cultural or other drivers of plant use. With cultural, biological, and linguistic diversity under threat, gaining a deeper and broader understanding of the variation of medicinal plant use through time and space is pressing
Multi-functionality of the few: Current and past uses of wild plants for food and healing in LiubaÅ\u84 region, Belarus
Background: This study examined the use of wild plants in the food, medicinal and veterinary areas within a small territory limited to one village council in the LiubaÅ\u84 district of Belarus. The objectives of the research were to document the current and past uses of wild plants in this region for food and human/animal medication; to analyse the food, medicinal and veterinary areas in the context of wild plants; and to qualitatively compare the results with relevant publications concerning the wild food plants of Belarus. Methods: Fieldwork was carried out as a practical part of a development cooperation project in May 2016 in 11 villages of the LiubaÅ\u84 district. One hundred thirty-four respondents were selected randomly. Information about local uses of wild plants was obtained via semi-structured interviews and the folk-history method. Interview records were digitalized and the data structured in Detailed Use Records (DUR), which were divided into food, medicinal and veterinary areas and then analysed to ascertain local perceptions. Results: A total of 2252 DUR of wild plants were recorded. Eighty-eight wild plant taxa belonging to 45 plant families were used across all three areas. Of these, 58 taxa were used in the food, 74 in the medicinal and 23 in the veterinary areas. A relatively high percentage of the taxa were used in both the food and medicinal areas (55%) and an even greater percentage in both the medicinal and veterinary areas (87%). Comparison with earlier research on wild food plants shows the considerable difference among seldom-mentioned taxa or uses, showing possible regional differences despite the homogenization of the population during the Soviet era. Conclusions: As the majority of taxa with overlapping uses belonged to the most utilized plants, there appears to be clear a tendency to use plants in several different areas once they are brought into the home. This may be due to the need to maximize the versatility of limited resources. While the number of wild taxa used is relatively high, the mean number of taxa used per person is quite low, which indicates the relatively minor importance of wild plants in the respective areas in the study region. The low importance of snacks signals that unintended contact with nature has been lost
Current and Remembered Past Uses of Wild Food Plants in Saaremaa, Estonia: Changes in the Context of Unlearning Debt
It is widely agreed that in industrialized Europe, knowledge on the use of wild food plants shows a decreasing trend with few instances of valorization. We employed a folk history approach in order to understand the changes that have occurred in the use of wild food plants within the lifetime of the older generation living on Saaremaa Island. Comparing current and remembered past uses and evaluating temporal encounters afforded the understanding that, while the general picture of the use of wild food plants seems diverse and promising (89 plant taxa used, median 20 taxa used per person, Informant Consensus Index of 0.9), only 36% of uses have been practiced throughout life. Another third (34%) of uses existed as a childhood memory, which also encompassed taxa useful during times of food shortage, and 20% of the uses recorded were recently abandoned. The uses of wild food plants acquired later in life, at some point during adulthood (4%) or recently (6%), were few in number, rather temporal in nature and affected by fashion trends. To understand the temporal changes in the use of wild food plants and to identify the reasons causing those changes, it may be important for future researchers to document the exact time of the actual use. To ensure the survival of food security-related knowledge, during times of relative food abundance, it is important to ensure the continuity of the use of wild food plants on the family level by educating children through their participation in making food from wild plants
A comparative analysis of medicinal and aromatic plants used in the traditional medicine of Iğdir (Turkey), Nakhchivan (Azerbaijan), and Tabriz (Iran)
A total of 341 naturally distributed taxa belonging to 65 families are used in the traditional medicine in Iğdır (Turkey), Nakhchivan (Azerbaijan), and Tabriz (Iran). Local people in three different regions generally use herbal remedies for digestive, respiratory, urogenital systems, as well as dermal, neurological and psyschological diseases. On the basis of localities three highly prevelant usesin Iğdır are colds (32 taxa), stomach disorders (28 taxa), and cough (24 taxa); in Nakhchivan rheumatism (24 taxa), gastrointestinal disorders (24 taxa), and anthelmintic (20 taxa), and in Tabriz diuretic (24 taxa), fever (22 taxa), and cough (20 taxa). Our findings reveal that in these three areas belonging to three neighbouring countries 4 taxa are widely distributed and used almost forthe same applications; Glycyrrhiza glabra (for digestive and respiratory systems), Malus sylvestris ssp. orientalis (for respiratory system), Rosa canina (for digestive and urinogenital systems), and Urtica dioica (for digestive system). The studied areas show several resemblances from cultural and other aspects. © 2018, Pakistan Botanical Society. All Rights Reserved
