Species with medicinal and mystical-religious uses in São Francisco do Conde, Bahia, Brazil: a contribution to the selection of species for introduction into the local Unified Health System

We investigated the knowledge and practices of local residents in São Francisco do Conde, Bahia, regarding the use of medicinal and mystical plants with the aim of proposing strategies for the incorporation of phytotherapies into the local Unified Health System through local Basic Health Clinics. This municipality was founded during the early colonization of Brazil, introducing the monoculture of sugarcane and slave labor to the region, resulting in a currently largely Afro-Brazilian population. Key informants and local specialists were interviewed and workshops were undertaken at the Basic Health Clinics to collect data and information. The interviewees made 254 references to 126 plant species distributed among 107 genera and 50 families. Among the species cited with medicinal or mystical uses, 51.6% were considered autochtonous, and 42.8% were cited in at least one document of the Brazilian Health Ministry; of these, 11.1% were mentioned in four to eight documents, indicating potential for introduction to the local Unified Health System. The valorization of local knowledge and practices concerning the use of medicinal plants represents an important approach to public health efforts.

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.
