“…Cymbopogon citratus, family Poaceae, was reported in an ethnoveterinary study as having anthelmintic activity (RITTER et al, 2012). Infusions or decoctions of dry leaves have been utilised as stomachic, antifever, antiseptic, carminative and tranquilising (ARHOGHRO et al, 2012;BORRELLI & IZZO, 2000).…”

Parasitic nematodes are of major economic importance in livestock. An alternative for the control of parasites is phytotherapy. This study evaluated the efficacy of Cymbopogon citratus decoction (CcD), C. citratus essential oil (CcEo) and citral against Haemonchus contortus using in vitro egg hatch test (EHT) and larval development test (LDT) and an in vivo test using a Meriones unguiculatus (gerbil) model. The effect of 800 mg/kg CcEo was evaluated in gerbils that had been artificially infected with 5,000 third-stage H. contortus larvae. The effective concentrations required to inhibit 50% (EC50) of egg hatching were 0.46, 0.14 and 0.13 mg/mL for CcD, CcEo and citral, respectively. The EC50 values in the LDT were 5.04, 1.92 and 1.37 mg/mL for CcD, CcEo and citral, respectively. H. contortus population in the group treated with C. citratus essential oil was reduced by 38.5% (P< 0.05) in comparison to the control group. These results suggest that it may be possible to use C. citratus essential oil to control of H. contortus parasite of small ruminant.Keywords: Phytotherapy, anthelmintic, Meriones unguiculatus, in vitro, citral. ResumoO parasitismo por nematoides tem grande importância econômica no rebanho. Uma alternativa para o controle de parasitas é a fitoterapia. Este estudo avaliou a eficácia do decocto de Cymbopogon citratus (DCc), do óleo essencial de C. citratus (OECc) e do citral contra Haemonchus contortus utilizando o teste in vitro de eclosão dos ovos (TEO) e o teste de desenvolvimento larval (TDL) e um teste in vivo com modelo Meriones unguiculatus (gerbil). O efeito de 800 mg/kg de OECc foi avaliado em gerbils infectados artificialmente com 5000 larvas de terceira fase de H. contortus. As concentrações efetivas necessárias para inibir 50% (CE50) da eclosão dos ovos foram 0,46; 0,14 e 0,13 mg/mL para DCc, OECc e citral, respectivamente. Os valores da CE50 no TDL foram de 5,04; 1,92 e 1,37 mg/mL para DCc, OECc e citral, respectivamente. No grupo tratado com óleo de C. citratus a população H. contortus foi reduzida em 38,5% (P < 0,05) em comparação com o grupo controle. Estes resultados sugerem que pode ser possível a utilização de óleo essencial de C. citratus para controle de H. contortus, parasita de pequenos ruminantes.Palavras-chave: Fitoterapia, anti-helmínticos, Meriones unguiculatus, in vitro, citral.

“…Current ecological themes also present a variety of approaches, especially regarding the different uses of wild fauna (Nishida et al, 2006;Alves and Santana, 2008;Alves et al, 2010a, b;Favoretto et al, 2011;Ritter et al, 2012). The use of fauna-derived products in popular medicine (zootherapy) has been the most studied subject, which encompasses studies performed in traditional Brazilian communities, especially in Brazil's northern and northeastern regions Alves, 2008).…”

Ethnozoology in Brazil: analysis of the methodological risks in published studies

et al. 2015

View full text Add to dashboard Cite

There has been a growth in the field of Ethnozoology throughout the years, especially in Brazil, where a considerable number of scientific articles pertaining to this subject has been published in recent decades. With this increase in publications comes the opportunity to assess the quality of these publications, as there are no known studies assessing the methodological risks in this area. Based on this observation, our objectives were to compile the papers published on the subject of ethnozoology and to answer the following questions: 1) Do the Brazilian ethnozoological studies use sound sampling methods?; 2) Is the sampling quality influenced by characteristics of the studies/publications? The studies found in databases and using web search engines were compiled to answer these questions. The studies were assessed based on their nature, sampling methods, use of hypotheses and tests, journal's impact factor, and animal group studied. The majority of the studies analyzed exhibited problems associated with the samples, as 144 (66.98%) studies were classified as having a high risk of bias. With regard to the characteristics analyzed, we determined that a quantitative nature and the use of tests are essential components of good sampling. Most studies classified as moderate and low risk either did not provide these data or provided data that were not clear; therefore, these studies were classified as being of a quali-quantitative nature. Studies performed with vertebrate groups were of high risk. Most of the papers analyzed here focused on fish, insects, and/or mollusks, thus highlighting the difficulties associated with conducting interviews regarding tetrapod vertebrates. Such difficulties are largely related to the extremely strict Brazilian laws, justified by the decline and extinction of some species, related to the use of wild tetrapod vertebrates.Keywords: scientometry, Ethnobiology, Ethnoecology, methodological biases. Etnozoologia no Brasil: análise de riscos metodológicos nos trabalhos publicados ResumoAo longo dos anos a Etnozoologia vem crescendo, principalmente no Brasil, no qual se observa um expressivo número de publicações científicas nas últimas décadas. Com isto abriu-se a oportunidade para avaliar a qualidade das publicações, já que não existem pesquisas que avaliem os riscos metodológicos na área. Partindo desta premissa objetivamos compilar os artigos publicados na área e responder as seguintes questões: os trabalhos etnozoológicos brasileiros possuem boa qualidade amostral? A qualidade amostral é influenciada por características dos estudos/publicações? Para responder tais perguntas foi realizado levantamento das publicações em bases de dados e sites de busca. As características avaliadas foram relacionadas à natureza, amostragem, uso de hipóteses e testes, fator de impacto do periódico e grupo animalBraz.

“…Among the aromatic lora of the Amazon region, there are more than a dozen species that provide essential oils that are used by the population for therapeutic purposes [12]. The decoction of Piper callosum leaves is used to treat diseases of the gastrointestinal tract [5,13,14]. Moreover, the tea of the decoction of Piper hispidum leaves is useful for the treatment of malaria.…”

Piperaceae, a Latin name derived from Greek, which in turn originates from the Arabic word babary-black pepper, is considered one of the largest families of basal dicots, found in tropical and subtropical regions of both hemispheres. The species that belong to this family have a primarily pantropical distribution, predominantly herbaceous members, occurring in tropical Africa, tropical Asia, Central America and the Amazon region. The Piperaceae family includes ive genera: Piper, Peperomia, Manekia, Zippelia and Verhuellia.Brazil has about 500 species distributed in the Piper, Peperomia and Manekia genera. The Piper genus, the largest of the Piperaceae family, has about 4000 species. Within the Piper genus, about 260-450 species can be found in Brazil. Piper species have diverse biological activities and are used in pharmacopeia throughout the world. They are also used in folk medicine for treatment of many diseases in several countries including Brazil, China, India, Jamaica and Mexico. Pharmacological studies of Piper species point toward the vast potential of these plants to treat various diseases. Many of these species are biologically active and have shown antitumor, antimicrobial, antioxidant, insecticidal, antiinlammatory, antinociceptive, enzyme inhibitor, antiparasitic, antiplatelet, piscicide, allelopathic, antiophidic, anxiolytic, antidepressant, antidiabetic, hepatoprotective, amebicide and diuretic possibilities.
