Despite this, research on medicinal use of animals is still neglected in comparison to studies on medicinal plants. This paper documents the medicinal use of animals by hunters residing in rural communities in the semiarid region (Caatinga) of Brazil. A total of 117 hunters provided information about the animal species used, body parts useful for preparing remedies and which diseases are treated with animal-based remedies. The Informant Consensus Factor and Use Value - Current / Potential were calculated to determine the consensus on which species are effective in treating specific diseases, and to measure hunting pressure on each species. The medicinal use of 39 animal species was registered, which were indicated to cure 46 ailments. The local medicinal fauna is largely based on wildlife, including endangered species. The high number of animals used by hunters makes it possible to conclude that any conservation strategy should include, in addition to an environmental approach, access to modern healthcare.

Cl. 8 : A01M, C11D 3/384, A01K 11/00, A01M 23/00, A21D 2/34, A61K 8/98, A61L 27/31, C07K 14/47 The widespread use of natural resources is a common practice in traditional medicine. Therefore, animals and their by-products are a significant part of the inventory of medicinal substances used by many peoples in different cultures since ancient times 1-4. Research on animals used for medical purposes is neglected in comparison to research on medicinal plants, even with the worldwide prevalence of the use of wildlife products in traditional medical practices 5. Current papers, however, have demonstrated the importance of zootherapy in various sociocultural contexts in the world, especially in developing countries 6. In Brazil, many species of wildlife are used for medicinal purposes since the colonial period, being therapeutic alternatives widely disseminated and available throughout the country 3,7-10, and many people continue to rely on zootherapy as an alternative or complement to the use of allopathic drugs 11,12. This practice seems common among hunters, as an attempt to maximize animal resources 9,13. *Corresponding author The use of animals for medicinal purposes is part of a set of traditional knowledge that has become increasingly relevant to discussion about fauna conservation, public health policies, sustainable management of natural resources, prospecting and biological patentes 14. In North eastern Brazil, especially in the semiarid region, animals and plants are widely used in traditional medicine and play a significant role in alternative treatments 15,16. Zootherapy is part of the culture in the semiarid of Brazil, and the knowledge about animal-based remedies is passed down through generations of hunters by oral tradition. Thus, the present paper aims to record the medicinal use of wildlife by hunters from two areas of the Brazilian semi-arid region. Methodology The work was carried out between August 2011 and October 2015 in the municipality of Queimadas (7º21'29" S, 35º53'53" W), and Fagundes (7º20'45" S, 35º47'51" W), located in the Agreste Mesoregion (Dry forest) of the state of Paraíba, Brazil. These municipalities are easily accessible and have

2 486 INDIAN J TRADIT KNOWLE, VOL 17, NO 3, JULY 2018 predominantly rural characteristics, with communities following traditional customs (sertanejos). Fagundes has an area of 162 km² and an approximate altitude of 505 m. The municipality has a total population of 11,409 inhabitants, 5,942 of them live in the rural area. Its Human Development Index (HDI) is ,18. Queimadas has an area of 409 km² and an approximate elevation of 450 m. The municipality has a total population of 41,054 inhabitants, of which 22,249 are in the urban area. Its Human Development Index (HDI) is ,19. The studied area is subdivided in many communities. The Salvador and Catucar communities in Fagundes, and the Gravatá and Velez communities in Queimadas were the areas sampled in this paper. The localities present between 90 and 130 residences, distant from one another and close to mountains with preserved vegetation 13,20. The local vegetation is hyperxerophilic with stretches of deciduous forest. The climate is represented by the semiarid tropical type, with autumn-winter rains and an average annual precipitation of mm 17,19. Procedures and data analysis Initially, hunters were identified with the help of residents of the areas studied, and later, those with specialized knowledge on animal-based remedies were selected for interviews by Snowball sampling 3,21. Before the interviews, all signed a free and informed consent term. Ethical approval for the research was obtained from the Comitê de Ética of the Universidade Federal da Paraíba (CAAE: ). Most of the hunters interviewed experience a stable marital relationship, by marriage or consensual union. The occupational activity of most of them is agriculture. The educational level of hunters is low, % of them have not completed primary school. The average monthly income of the interviewees is 1.37 minimum wage (around R$ 1300) per capita (around US$ 400). The families present, in % of the cases, three individuals per residence. Most of the interviewees are from the area surveyed, and have lived throughout their lives in the same region. The interview questions were about the local name of the animal used as medicine; by-products and used parts; treated diseases; use of medicinal products; spiritual aspects related to the use; use of live or dead animals; obtaining animals; dependence on wildlife medicinal products; reasons for using zootherapeutic drugs and transmission of traditional knowledge. The common names of the species were recorded as cited by the interviewees. The animals were identified by expert taxonomists (I) through examining samples donated by the interviewees; (II) observing photographs of the animals or their parts, visualized during the interviews; (III) using the vernacular names. All specimens and photographs were deposited at the Departamento de Ciências Biológicas of the Universidade Federal de Campina Grande. The treated diseases were grouped into 14 categories (Table 1), based on the classification used by the Centro Brasileiro de Classificação de Doenças 22. To estimate the level of agreement between interviewees over which animals to use for each category, we calculated the informant consensus factor ICF, (adapted 23 ) that quantifies the variability of animals used for each treatment, and therefore the consensus between practitioners. ICF = (NUR NS) / (NUR 1) Where, ICF = Informant Consensus Factor; NUR = number of use-reports in each category; NS = number of species used. The ICF score ranges from 0 to 1. A value close to zero may indicate high variation in species utilization, or if animals are randomly selected, or if informants do not exchange information about wildlife use. Values close to one indicates the high intracultural consensus. For each animal cited, the use value UV (adapted 24,25 ) was calculated. The use value (current and potential) was calculated using the following formulas: (UV C = ΣU C /n) e/ ou (UV P = ΣU P /n) Where, UV C = current use value of the species (species known and effectively used); UV P = potential use value of the species (species of known use, but not currently used); U C = number of citations of current use per species; U P = number of citations of potential use per species; n = number of informants. This differentiation in use values was important to minimize some calculation limitations, since the classic UV 24 does not distinguish between actual use and past use, which could overestimate or underestimate the analysis 13.

They were aged between 32 and 79 yrs old (with an average age of 53 yrs old). The hunters cited a total of 39 species distributed in 34 wildlife families that are used as medicinal animals for the treatment of 46 diseases in the region. This sampling is high compared to other studies that list the medicinal animals in the region 13,26,27. It is necessary to consider both the knowledge and socioeconomic conjuncture of hunters using zooterapeutic drugs 20,28. This knowledge, coupled with the life stories, makes the hunters understand very well the ecological dynamics of the hunted species, which makes them important and with enormous potential to assist, under expert guidance, strategies of environmental and cultural conservation. The species recorded in this paper are basically arthropods and terrestrial tetrapods found in the region's ecosystem. This fact supports other research that exposes the tendency to use biodiversity in the ecological zone where people live 3,29. Four species are not part of the local fauna (Caiman sp., American rhea, Struthio camelus, Trichechus inunguis), and hunters reported acquiring their derivatives at fairs and formal and informal animals markets in the region. Part of the fauna is illegally traded. Several works denounce the illegal wildlife trade in the North east of Brazil, including zootherapy as one of the main justifications for its maintenance 30,31. This paper reinforces this claim, especially through the registration of derivatives of animals at risk of extinction, such as the Trichechus inunguis 32, which is freely marketed in the studied area. The most cited species were Salvator merianae (n=177), Caudisona durisa (n=154), Iguana iguana (n=130). The UV C varied between zero and 1.265, and the UV P varied between zero to An amount of 31 species (79.5 %) presented UV C higher than UV P, and eight species only showed UV C, which constitutes a strong indication of the continuous pressure of the zootherapeutic practices upon the local fauna. In addition, six species (Salvator merianae; Caudisona durisa; Iguana iguana; Cerdocyon thous; Mesoclemmys tuberculata; Cavia aperea) showed a UV C greater than 0.3, which indicates the current risk of local overexploitation of these animals. A total of six species (15.4 %) presented a higher UV P than UV C, with three species presenting only VU P. For some animals like Amazona aestiva, this may be a sign of their local absence. This evidence is reinforced by the hunters' opinion on the scarcity of this species in the region. Another possibility is that the local culture of consuming animal-based remedies might have changed, making fundamental a more

4 488 INDIAN J TRADIT KNOWLE, VOL 17, NO 3, JULY 2018 profound ecological analysis on these animal populations in the studied area. The hunters cited the following by-products as remedy: meat, bones, tail, feathers, paws, teeth, head, stomach, liver, gizzard, eggs, fat, abdomen, viscera and feces (Table 2). The zootherapeutic products listed in this paper corroborate other records for the North east Region of Brazil 3, for other regions of the country 33, for Latin America 34 and other areas 35-37, which demonstrates the undisputed dissemination of these practices and makes it essential to analyze the efficacy of these by-products. Animal-based remedies were used to treat 46 illnesses. The categories of diseases with the highest number of species used as treatment were respiratory diseases (18 species, 367 use citations), undefined diseases (12 species, 204 use citations) and diseases of the musculoskeletal system and connective tissue (8 species, 185 use citations). The IFC values were above 0.9 for nine of the categories of diseases listed (Table 3). The low number of species citations for some categories influenced this result, but it is worth mentioning the results for musculoskeletal disorders (IFC = 0.96), respiratory diseases and undefined diseases \(IFC = 0.95), that presented high ICF, despite the fact that more than 12 species were cited on average. Different parts of a single species can be used as raw materials to prepare different remedies, which are prescribed for the treatment of various diseases. The possibility of using different zootherapics for the same disease or the same animal to treat different diseases may be an adaptation of the hunters to the availability of animals 11,38,39. The local zootherapeutic products are used mainly for the treatment of diseases of the respiratory system, such as asthma, bronchitis, effusion, catarrh, cough, sore throat, sinusitis and tonsillitis. A similar trend in relation to medicinal animals was recorded in cities of North and North east Brazil 3,11,12,16,40,41. This fact amplifies the need to understand the zootherapeutic practices in the context of biodiversity conservation in the country 3,30. Besides being used for the elaboration of traditional medicines, the animals are also used as amulets in mystical cures, such as Cavia aperea (amulet to treat dentition) and Caudisona durisa (the rattle is used as an amulet to avoid snake bites). Due to this mystical aspect (superstitions), there has been a trend towards the use of live animals, as with Cyanocorax cyanopogon and Chelonoidis carbonaria, which are credited wih being capable of curing respiratory diseases with the symbolic rite of feeding them with the patient's food remains. Diseases with supernatural causes exist in different cultures 42, so, because traditional medical systems are organized as cultural systems, the use of wildlife substances, in addition to an ecological perspective, must also be understood from a cultural perspective 43. In every society there are beliefs that can be easily abandoned and there are ones that are strongly rooted within a culture, making them hard to change. This aspect is particularly relevant to the modes of disease transmission and how they can be effectively treated 44. In a study about the use of animals in zootherapy in fishing communities in the North and North east of Brazil, Alves 45 records that in the communities surveyed, besides the animals supplying raw material for the treatment of diseases using clinical methods, their products are also used in form amulets and spells in order to prevent and treat diseases associated with unnatural causes. The present work also identified that 21 species are on lists of threatened animals, such as Dasypus novemcinctus and Trichechus inunguis 32,46. Unscrupulous use of animal products in traditional medicine may result in undesirable consequences, including illegal wildlife trade and animal population reduction. Hence, the medicinal use of animals should be considered in conjunction with other forms of anthropogenic pressure 3,47. There is the necessity to increase understanding of the biology and ecology of species traditionally used as zootherapics to better assess the impacts of this form of use. Medicinal use of threatened species must receive urgent attention, and the loss and alteration of their habitats should be discussed in combination with current and future medicinal uses in order to preserve the bioprospecting potential of the fauna in Brazil 3,31. Biotherapeutic activities, if well managed, may be compatible with environmental conservation programs where the use of natural resources can and should occur in such a way that the fulfillment of human needs and the protection of biodiversity are guaranteed 11.

The high consensus among the hunters interviewed for the treatment of some categories of diseases makes it possible to infer that the use of animal-based remedies in the region is based on traditional systems of health perpetuated for generations. It is urgent to consider the hunting pressure exerted by the use of medicinal wildlife in the Brazilian semi-arid, since this form of use of the natural resources is related to the social and economic aspects of the local populations.
