| This study aimed to define the current status of ethnobotanical research in Brazil based on published scientific articles and to detect current knowledge gaps in Brazil's ethnobotany. A database, including articles published in national and international scientific journals from 1988 to 2013, was gathered for this purpose. This report discusses the growing number of publications in ethnobotanical research and the main techniques used in the discipline. To identify current knowledge gaps, his report emphasizes the main focus of the different studies, target regions, and communities targeted or involved in the original study. Most publications focused on the northeast and southeast Brazil, and the most frequently studied biomes were the Caatinga and Atlantic... |

| A distribuição geográfica das 39 espécies nativas de Mikania Willd. no Rio Grande do Sul foi estudada em duas escalas: uma escala regional, utilizando regiões fisiográficas como unidades, e uma escala continental, considerando regiões político-geográficas como unidades. A riqueza específica e a amplitude de distribuiçãoforam obtidas diretamente de matrizes de presença e ausência, relacionando espécies e regiões. A matriz regional foi analisada por dois métodos multivariados, uma análise de agrupamentos e uma análise de coordenadas principais, utilizando o complemento do coeficiente de Jaccard como elemento de comparação (dissimilaridade). Na escala regional as regiões mais ricas foram o Litoral e a Depressão Central, enquanto na escala continental, a... |

| ABSTRACT Among the medicinal purposes for which plants have been used is the treatment of “nerves". The objective of this study was to search for species of plants used in the state of Rio Grande do Sul (South Brazil) for the relief of symptoms related to central nervous system (CNS) disorders. Twenty-seven ethnobotanical studies were compiled, in which a total of 94 species were cited. The five most cited species were Cymbopogon citratus (81.5 %), Melissa officinalis (77.7 %), Aloysia citriodora (66.6 %), Matricaria chamomilla (62.9 %) and Passiflora edulis (51.8 %). Scientific studies have corroborated the popular use of these plants as sedatives, but most studies are preclinical and very few have been clinical (M. chamomilla and M. officinalis), and... |
