The use of domestic animals and their derivative products in contemporary Spanish ethnoveterinary medicine.

Abstract: This review documents the wide and varied repertoire of traditional practices and remedies based on the use of domestic animals 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 local veterinary knowledge (LVK) and research addressing the discovery of new drugs for livestock and the validation of the effects. Methods: A qualitative systematic review of the most important databases in the fields of ethnobiology, ethnoveterinary medicine, folklore and ethnography was performed. Information and use-reports were obtained from more than 60 documentary sources. Results: We recorded the use of nine domestic animal species and one hybrid (the mule) and a total of 171 empirical remedies based on the use of a single species. A wide diversity of body parts or derivative products were/are used. Fat was/is the most commonly used product, being used in 71 remedies (42%). These zootherapeutic resources were/are used to treat or prevent a total of 69 animal diseases or medical conditions, in particular dermatological, reproductive and digestive ailments, together with some infectious diseases. Sheep, cattle, goats and equines form the group of domestic animals in which the greatest number of useful species is employed. In addition, many remedies and practices of the magical-religious type are documented. In comparison with other culturally related areas, there is a greater parallelism in the animals and body parts and derivative products used, and the ailments treated. Conclusions: Contemporary Spanish EVM practices amass a great richness of domestic animal-based remedies. A diversity of body parts or derivative products has 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, and it can contribute to the creation of new strategies for the conservation of natural resources and management of endangered species. The usage of zootherapeutic products derived from wild animals can be replaced by the use of products isolated from domestic animals. Finally, this overview contributes to the inventory of some uses, traditional practices and rituals seriously threatened by the progressive loss of LVK.
