Ethnobotanical study of medicinal plants traditionally used in the Arribes del Duero, western Spain.

AIM OF THE STUDY We studied traditional knowledge (TK) and current uses of medicinal plants among the inhabitants of the Arribes del Duero-ARD-(Spain), documenting traditional medical practices. MATERIALS AND METHODS We interviewed 80 key informants (44 men and 36 women). Their average age was 72 years (range 48-98 years). We calculated the cultural importance for each species cited. To analyze how TK varies with the characteristics of the different informants, we performed an ANCOVA, taking the number of use-reports (URs) provided by each informant as a variable to model, and age and gender as explanatory variables. RESULTS AND CONCLUSIONS 156 medicinal remedies were recorded; they were based on a single species and were cited by at least three independent informants, and half of them are still in use today. These remedies are related to nine major organ systems and 54 therapeutic uses, and 70 species (belonging to 39 families) are used, most of which are herbs (64%). The most relevant family is the Lamiaceae (23 remedies, 8 species) and the species employed in the greatest number of remedies (8) is Urtica dioica L. However, the taxon with the greatest cultural value is Hypericum perforatum L. (CI=0.71). 31% of the variability of the TK can be explained in terms of the age and gender of the informants (R(2)=0.315), the age factor having a positive effect. Most of the remedies are related to the treatment of unimportant ailments, referring to disorders of the skin, and the respiratory and digestive systems. The leaves and fruits are the most frequently sought plant parts (40 and 17% of the plants mentioned, respectively), and infusions (34%) and decoctions (28%) are the main methods used for preparing the remedies. Likewise, we recorded remedies based on plant mixtures and ethnomedicinal novelties or rare uses, and comment on the influence exerted by superstition. Currently, many people preserve a rich TK about medicinal plants, and it may be affirmed that the folk medicine is still very much alive in the ARD, above all as regards the treatment of certain common afflictions or unimportant ailments.

The consumption of wild and semi-domesticated edible plants in the Arribes del Duero (Salamanca-Zamora, Spain): an analysis of traditional knowledge

The collection and consumption of wild (including naturalized) and semi-domesticated (cultivated and reverted to wild status, and neglected cultivated plants for food) edible plants in the rural communities of the Arribes del Duero (western Spain), a highly heterogeneous Mediterranean agroecosystem, were analysed. Through semi-structured interviews with 80 informants, data on the gathering, preparation and consumption of 76 wild edible plant species were acquired. To analyze how traditional knowledge varies with the characteristics of the informants, we performed an ANCOVA. The “age” variable was found to have a significant effect. The most frequently cited species in the study area (i.e. Rubus ulmifolius, Foeniculum vulgare, Quercus ilex, Laurus nobilis, Origanum vulgare) are widely consumed in the Mediterranean region. Also, from a cluster analysis it was observed that the grouping succession this territory matches those of analysed areas of the Iberian southwest. Certain species have traditionally been consumed as an important supplement to the diet, particularly during food shortages (i.e. Rumex induratus, Chondrilla juncea). Several species are ethnobotanical novelties, among which are Erodium botrys and Astragalus pelecinus, whose immature fruits are eaten raw as a snack. Some ecological and cultural aspects of the gathering of wild plants for food are discussed.

Ethnoveterinary medicine in the Arribes del Duero, western Spain

Currently, traditional ethnoveterinary practices are rare in Europe and the plants used previously have been replaced by the modern drugs used by national veterinary services. However, in some rural areas of the Mediterranean basin these traditional practices persist. Here we analyze the plant resources still used, or that have been used up until recently, for the treatment of the health and comfort of animals in a region in the central-western part of the Iberian Peninsula, the Arribes del Duero. We document the use of 84 species, belonging to 39 families (with a total of 2243 use-reports), and 62 herbal remedies based on the use of a single plant species (43) and cited by at least three independent informants. The veterinary use of the Ranunculaceae Clematis campaniflora is reported for the first time. We also identify several plants used as bedding or fodder for livestock and discuss the relevance of some toxic plants and some “magical-curative” aspects reported in the territory.

Diversity and Biogeographical Significance of Solitary Wasps (Chrysididae, Eumeninae, and Spheciformes) at the Arribes del Duero Natural Park, Spain: Their Importance for Insect Diversity Conservation in the Mediterranean Region

ABSTRACT Between 1997 and 2005, a study was made of the Chrysididae, Eumeninae, and Spheciformes wasps in the Arribes del Duero Natural Park (Provinces of Salamanca and Zamora, western Spain), a highly heterogeneous Mediterranean landscape. We collected, respectively, 127, 57, and 230 species of these groups, constituting ≈50% of the species known for the Iberian Peninsula. The inventory was fairly complete according to the final slope of the species accumulation curves. From a biogeographic point of view, the predominant elements of the Arribes del Duero fauna are Mediterranean in the broad sense, together with a high percentage of species of Euro-Atlantic distribution. The proportion of endemic species obtained is similar to those known for the whole of the Iberian Peninsula. The species endemic to the northern subplateau and to the southwestern quadrant predominate. The Arribes del Duero territory is the northern limit of the distribution of some Iberian-Maghrebine species, although it is also the southern limit of species widely distributed throughout central and northern Europe. The Atlantic influence in the territory has facilitated the persistence of some species, with an Atlantic or sub-Atlantic distribution, related in particular to riparian forests. This space constitutes a large eco-corridor that joins the north of the Peninsula to the south, linking communities corresponding to the Eurosiberian and Mediterranean biogeographic regions and to territories encompassed within the Temperate and Mediterranean macrobioclimates. Thus, because of its geographic situation and extensive latitudinal range, together with the fact that it has a good representation of European biodiversity, the Arribes del Duero Park is proposed as a priority area for insect diversity conservation in the Mediterranean region.

Traditional plant-based remedies to control insect vectors of disease in the Arribes del Duero (western Spain): an ethnobotanical study.

ETHNOPHARMACOLOGICAL RELEVANCE In several Spanish rural communities, simple and effective plant-based remedies are employed for the control of vector-borne diseases. Hence, the aim of this study was to assess the knowledge and usage custom of traditional insect control in the Arribes del Duero-ARD-(Salamanca-Zamora, W Spain). MATERIALS AND METHODS Between 2005 and 2009, 116 semi-structured interviews of 80 non-specialist people (44 men and 36 women; mean age, 72) were conducted. This community was located in the Arribes del Duero Natural Park, representative of a highly heterogeneous Mediterranean landscape with a strong decline in the population and a significant proportion (almost 40%) age 65 or greater. We calculated the cultural importance for each species cited. To analyze how traditional ecological knowledge (TEK) varies with the characteristics of the informants, we performed an ANCOVA. RESULTS AND CONCLUSIONS We documented the traditional use of 22 vascular plants as remedies to prevent or treat external parasites, and control mosquitoes, flies and other nuisance insects. There were described 27 plant remedies, of which 16 (59%) continue to be in use, including basil (Ocimum basilicum L. and Ocimum minimum L.) as a repellent for mosquitoes and houseflies. Most of the plant species contain phenols and/or terpenoids, and in several investigations bioassays have been performed to test their repellent and/or insecticidal properties. Three taxa (Ballota nigra L., Cicer arietinum L. and Ocimum minimum) have not been tested and these may offer excellent natural remedies. As well as allowing the discovery of new chemical compounds with insecticidal activity, this traditional knowledge may be paramount in the control of potential populations of vectors of emerging diseases in the Mediterranean region without harming the environment.

The use of wild vertebrates in contemporary Spanish ethnoveterinary medicine

ETHNOPHARMACOLOGICAL RELEVANCE This review documents the wide and varied repertoire of traditional practices based on the use of wild vertebrates in Spanish ethnoveterinary medicine (EVM) from the early 20th century to the present. Empirical practices, both ritual and magical, are recorded, and these EVM data are compared with those of other countries in the Mediterranean Region and Latin America. The data collected here could form a scientific foundation for future inventories of traditional knowledge and help in the discovery of new drugs for livestock. MATERIALS AND METHODS A qualitative systematic review of international and national databases in the fields of ethnobiology, ethnoveterinary medicine, folklore and ethnography was made. Information was obtained from more than 60 documentary sources. RESULTS We recorded the use of 30 wild vertebrates and a total of 84 empirical remedies based on the use of a single species. The two most relevant zoological groups are reptiles and mammals. A wide diversity of body parts or products have been and are used. The meat and skin of snakes are the animal products most commonly used. These zootherapeutic resources have been and are used to treat or prevent ca. 50 animal diseases or conditions, in particular digestive and reproductive ailments, together with some infectious diseases. Sheep, cattle and equines form the group of domestic animals in which the greatest number of useful species are employed. In addition, many remedies and practices of the magical type are documented. In comparison with other culturally related areas, this is a rich heritage. CONCLUSIONS Contemporary Spanish EVM practices amass a great richness of wild animal-based remedies. A diversity of animal parts or products have been used, offering a cultural heritage that could be a fundamental step in the discovery of new and low-cost drugs for treating livestock and alternative materials for pharmaceutical purposes. This overview contributes to the inventory of some uses and rituals seriously threatened by the progressive loss of local veterinary knowledge.

The use of the head louse as a remedy for jaundice in Spanish folk medicine: an overview

BackgroundIn Spain, head lice are considered a therapeutic resource for the treatment of jaundice. All folk remedies based on the ingestion of these insects meet in the present document, previously dispersed among a large number of references.MethodsAn overview of the Spanish literature has been carried out. The most important databases have been consulted. All related works have been examined.ResultsAlthough the method of preparation is diverse and the dose varies, the primary recommendation is a transference ritual consisting of taking nine live lice for nine days on an empty stomach without the patient’s knowledge. This traditional knowledge survives in Spanish society, and constitutes an example of the interrelation between Spanish and Latin American folk medicines.ConclusionsThe survival of this therapy in the worldview of certain rural communities suggests the need to take into account the beliefs, ideas and behaviour patterns of popular culture in relation to health and disease.Resumen (in Spanish)AntecedentesEn España, los piojos de la cabeza son considerados un recurso terapéutico para el tratamiento de la ictericia.

Se han examinado todos los trabajos relacionados.ResultadosAunque el método de preparación es diverso y la dosis varía, la recomendación principal es un ritual de transferencia consistente en tomar nueve piojos vivos durante nueve días en ayunas y sin el conocimiento del paciente. Este conocimiento tradicional sobrevive en la sociedad española, y constituye un ejemplo de la interrelación entre las medicinas populares española y latinoamericana.ConclusionesLa supervivencia de esta terapia en la cosmovisión de algunas comunidades rurales sugiere la necesidad de tener en cuenta las creencias, ideas y patrones de comportamiento de la cultura popular en relación con la salud y la enfermedad.

Therapeutic and prophylactic uses of invertebrates in contemporary Spanish ethnoveterinary medicine

Zootherapeutic practices in ethnoveterinary medicine are important in many socio-cultural environments around the world, particularly in developing countries, and they have recently started to be inventoried and studied in Europe. In light of this, the purpose of this review is to describe the local knowledge and folk remedies based on the use of invertebrates and their derivative products in contemporary Spanish ethnoveterinary medicine. An overview in the fields of ethnozoology, ethnoveterinary medicine and folklore was made. Automated searches in the most important databases were performed. All related works were examined thoroughly and use-reports were obtained from 53 documentary sources. The traditional use of 18 invertebrate species and five ethnotaxa and a total of 86 empirical remedies based on the use of a single species was recorded. The two most relevant zoological groups were found to be insects and molluscs. A broad diversity of body parts or derivative products have been and are used to treat or prevent ca. 50 animal diseases or conditions, in particular diseases of the skin and subcutaneous tissue, different infectious livestock diseases, and disorders of the eye and adnexa. Cattle, sheep and equines form the group of domestic animals in which the greatest number of remedies are mentioned. In addition, seven magical remedies and practices are documented. In comparison with other culturally related areas, this is a rich heritage. The use-reports included here will help in the search for new and low-cost drugs for treating livestock and alternative materials for pharmaceutical purposes, future research addressing the validation of the effects and the development of organic farming.

Plant Remedies against Witches and the Evil Eye in a Spanish “Witches’ Village”

Plant Remedies against Witches and the Evil Eye in a Spanish “Witches’ Village.” An ethnobotanical survey was carried out to understand the traditional knowledge and current use of different preventive and curative plant remedies against witches and the evil eye in a Spanish rural community (Villarino de los Aires, Salamanca). Located in a Spanish region known as “Arribes del Duero,” this locality has historically been considered an important “witches’ village.” An anonymous questionnaire was answered by 52 people living in the village. The cultural importance index (CI) of each species was calculated. To analyze how knowledge varies as a function of the socio-demographic characteristics of the different informants, an analysis of covariance (ANCOVA) was performed, taking as variable to model the use-reports provided, and as explanatory variables the age, gender, and educational status. Age was the only variable that explained the variety in the number of plant remedies known; people over 60 knew significantly more plant remedies. Fifteen vascular plants were mentioned. The preventive remedies were particularly associated with key moments of the religious calendar. Branches gathered from olive trees, laurel, and/or rosemary are blessed on Palm Sunday, and then placed on window sills to protect people’s homes. During the celebration of Saint John’s Bonfire, aromatic plants are burnt, and the purifying and protecting power of the smoke emerges. The traditional use of plants hung behind doors of houses and stables to repel witches, and rituals for curing evil eye affecting people, animals, or even possessions were also revealed. Even today in rural communities of western Spain, there is a clear connection between popular religious and magic beliefs and their relationship with nature, especially plants.AbstractRemedios vegetales contra las brujas y el mal de ojo en un “pueblo de brujas” español. Se ha llevado a cabo un estudio etnobotánico sobre el conocimiento tradicional y el uso actual de diferentes remedios vegetales preventivos y curativos contra las brujas y el mal de ojo en una comunidad rural española (Villarino de los Aires, Salamanca). Esta localidad, situada en el extremo centro-occidental de España, concretamente en la comarca de Arribes del Duero, es reconocida como un importante “pueblo de brujas” desde antiguo. Se ha entregado un cuestionario que han rellenado, de forma anónima y unipersonal, 52 habitantes de la localidad. Se ha calculado el índice de importancia cultural (CI) para las diferentes especies vegetales citadas. Para analizar cómo varía el conocimiento en función de las características de los diferentes informantes, se ha realizado un análisis de covarianza (ANCOVA), tomando como variable del modelo los “registros de uso” aportados, y como variables explicativas la edad, el sexo y el nivel educativo. Solamente afecta, positivamente, la variable “edad,” habiendo aportado un mayor número de remedios vegetales las personas mayores de 60 años. Un total de 15 plantas vasculares han sido mencionadas. Los remedios preventivos tienen especial relación con momentos clave del calendario religioso. Durante el Domingo de Ramos se bendicen ramos confeccionados con olivo, laurel y/o romero, que posteriormente se colocan en ventanas para proteger las casas. Durante la celebración de la hoguera de San Juan se queman plantas aromáticas y se aprovecha el poder purificador y protector del humo. Asimismo, se ha recogido el uso tradicional de plantas repelentes de las brujas, plantas que son colgadas detrás de las puertas de casas y cuadras, y de rituales de curación de personas, animales, e incluso posesiones. Se puede asegurar que en comunidades rurales del occidente español, aún en la actualidad, la religiosidad popular y la magia aparecen claramente relacionadas con la naturaleza, sobre todo con el entorno vegetal.

Plant-based remedies for wolf bites and rituals against wolves in the Iberian Peninsula: Therapeutic opportunities and cultural values for the conservation of biocultural diversity

ETHNOPHARMACOLOGICAL RELEVANCE Combined approaches to local knowledge and folk plant use improve awareness and promote effective strategies for the conservation of significant biocultural patrimony. Moreover, the information reported might be the basis for further appropriate phytochemical and pharmacological research. Therefore we provide an insight into traditional herbal remedies and practices for healing bite injuries in humans and domestic animals caused by the Iberian wolf. Wolf bites are associated with inflammatory processes and rabies is a potential complication AIMS: This paper describes and summarises the medicinal-veterinary empirical and ritual uses of the Iberian flora for wolf injuries and reviews the ethnopharmacological data of specific plants that are already published. The Iberian wolf is a critically endangered subspecies of the grey wolf. Livestock attacks attributed to wolves are increasingly frequent in the Iberian Peninsula, resulting in serious social problems. Interesting strategies for Iberian wolf conservation might be related to traditional grazing practices that are deeply linked with empirical knowledge and local practices passed on by oral tradition, which are also vulnerable now. MATERIALS AND METHODS Based on documentary sources from the beginning of the twentieth century to the present, we systematically searched old monographs, regional documents, technical papers, project reports, as well as the international and national databases and the available scientific literature, without restrictions regarding the language of the publications consulted. RESULTS A total of 39 remedies for healing wolf bite injuries in humans and domestic animals was reported, highlighting the medicinal use of 33 species of vascular plants, mostly wild herbs, belonging to 18 botanical families. The use of wood ashes was also reported. The number of use-reports found represents a very high number considering similar European studies. Leaves were the predominant plant part mentioned. Boiling plant materials in water for topical uses was the most frequent method of preparation found. Some traditional remedies combined two or more plant species in order to potentiate their effects. Moreover, some plant-based traditional practices and rituals to ward off wolves and to prevent wolf attacks were also documented. In these practices eleven other species (belonging to seven more families) were used. CONCLUSIONS Despite the decline of the Iberian wolf over the last few decades, wolves are still in the imaginary of rural communities that perceive this large carnivore as both a diabolic creature and a mythic and benign animal. Wolf-related cultural heritage is of great interest in terms of conservation strategies. This review emphasises the importance of local knowledge and provides useful information about several potential sources of phytochemicals and their claimed therapeutic effects, aiming at contributing to the conservation and appreciation of the Iberian biocultural heritage.
