Women's ethnomedicinal knowledge in the rural community of São José da Figueira, Durandé, Minas Gerais, Brazil

São José da Figueira is a rural community which economy is based on small-sized family-owned agricultural and dairy farms. Rural communities often possess medicinal plant knowledge because not only does the rural lifestyle promote this but also because these communities coexist with a wide variety of plants. The aim of this study was to survey the knowledge of the community on plants and their medicinal uses. For data collection, semi-structured interviews and guided tours were carried out. Data were analyzed through the Major Use Agreement. All of the 34 informants were women. Plants were the first choice for use for primary health care by 75% of the interviewees. Of the total of 165 species identified, most species are exotic (45%), obtained by collection in home gardens (88%), and of herbaceous habits (65.7%). Leaves were the plant parts most often used (52%). Decoction was the most widely used form of preparation (41%), and oral intake was cited most often (66.4%). Leonurus sibiricus showed the highest value of Major Use Agreement (77.3%), in agreement with its popular use to treat diarrhea. The information obtained in this study showed that women in the community have extensive knowledge regarding medicinal plants. The home garden is a space where useful medicinal plants are maintained, and is the main location where these plants are gathered. .

Antinociceptive effects of Abarema cochliacarpos (B.A. Gomes) Barneby & J.W.Grimes (Mimosaceae) / Efeito antinociceptivo de Abarema cochliacarpos (B.A. Gomes) Barneby & J.W.Grimes (Mimosaceae)

In this study, we investigated the analgesic activity of crude aqueous and methanol extracts obtained from Abarema cochliacarpos bark in mice, and analyzed its phytochemical profile. All the extracts exhibited analgesic properties against the writhing test in mice, but the aqueous and methanol extracts were more active, and more potent than two known analgesic and anti-inflammatory drugs used as reference. They were also active against the capsaicin-model, but inactive when evaluated in the hot-plate test. Phytochemical studies revealed the presence of saponins, catechins, tannins, phenols and anthraquinones.

No presente trabalho foram avaliados a atividade antinociceptiva e o perfil fitoquímico dos extratos aquosos e metanólico produzidos com a casca do caule de Abarema cochliacarpos, uma espécie de Mata Atlântica com diversas indicações populares. Todos os extratos apresentaram atividade analgésica quando avaliados pelo teste das contorções abdominais induzidas pelo ácido acético via intraperitonial, apresentando respostas superiores às drogas usadas como referência, bem como no modelo da dor induzida por capsaicina. A avaliação fitoquímica demonstrou a presença de saponinas, catequinas, taninos, fenóis e antraquinonas.
