ABSTRACT
Forty-four medicinal species are cultivated at CESAM (Muribeca Alternative Health Center). The most frequent uses cited are related to the respiratory, digestive, and nervous systems. The phytotherapics most sold at CESAM, based on Justicia pectoralis var. stenophylla and Petiveria alliacea, are listed as toxic. In addition to these, eight other species are noted by specialists as toxic. A procedure to minimise the undesirable effects of such plants is also described.
Cuarenta y cuatro especies medicinales son cultivadas en CESAM (Muribeca Centro de Salud Alternativa). Los usos más frecuentes están relacionados con los aparatos respiratorio, digestivo y nervioso. Las hierbas más vendidas en CESAM, basadas en Justicia pectoralis var. stenophylla y Petiveria alliacea, también se consideran tóxicas. Además de éstas, otras ocho especies son identificadas por los especialistas del CESAM como tóxicas. En éste estudio, también se describe un procedimiento para reducir al mínimo los efectos indeseables de éstas plantas.

Objetivo: analisar a percepção de idosos sobre a importância do Grupo de Convivência. Métodos: pesquisa exploratória, descritiva, com abordagem qualitativa, desenvolvida em uma Unidade Básica de Saúde em um município do nordeste brasileiro, com 13 idosos que frequentavam o Grupo. Coleta dos dados por meio de entrevista semiestruturada e análise mediante técnica de análise temática. Resultados: foram identificadas três categorias empíricas: motivação ao procurar o grupo de convivência, perspectiva em relação a este e mudanças percebidas pela participação. Conclusão: o grupo de convivência pode representar um momento terapêutico para idosos, servindo de apoio e fortalecendo o idoso no contexto social, tornando possível o aprimoramento e o desenvolvimento de habilidades e obtenção de mais conhecimentos para promoção da saúde.

Piper aduncum L., Piperaceae, has been used to treat mainly inflammatory diseases and has shown several biological activities such as insecticidal and larvicidal. The aim of this study was to analyze the chemical composition of essential oil of P. aduncum and its efficacy to egg-hatching inhibition of Haemonchus contortus from sheep. The essential oil was obtained from leaves and analysed by gas chromatography coupled to flame ionization detector and gas chromatography coupled to mass spectrometry. It was possible to characterize 22 different substances, among them monoterpenes (80.6%) and sesquiterpenes (13.9%). The major compound was identified as 1,8-cineole (55.8%). Eggs of the nematode were exposed to four concentrations of the essential oil. Levamisole phosphate was used as positive control. The essential oil showed to be effective in inhibiting H. contortus hatchability and the LC90 was calculated as 8.9 mg.ml-1. These results can point out the P. aduncum essential oil and its chemical components as potential alternative to control of H. contortus .
