Plants used by the rural community of Bananal, Mato Grosso, Brazil: Aspects of popular knowledge

Abstract

Studies in rural communities are important to maintain popular knowledge between generations, as well as to identify new species for pharmaceutical production. Thus, the objectives of this study were to determine which plant species the rural community of Bananal, Mato Grosso, Brazil, uses by calculating the levels of fidelity and concordance regarding species uses among residents and to determine if there is a relationship between the number of known useful plants and levels of education, age, and residence time. Ethnobotanical data was collected from residents of the community through semi-structured interviews in January/December/2016. Species diversity was calculated using Shannon-Wiener, Level of Fidelity (LF), Correction Factor, and the Percentage of Agreement regarding the Main Uses (AMU). Statistical tests were performed using generalized linear models (GLM) in the R environment. The plant use indications were grouped according to the International Classification of Diseases and Related Health Problems (ICD 10). We found 152 species belonging to 130 genera and 67 families. The most frequently used plant parts were leaves, and decoction was the most frequent preparation mode. Strychnos pseudoquina was the species with the highest amount of use indications. The diversity index was 4.5 nats/ind-1. The body system with the most citations was the code XVIII of ICD 10, corresponding to the species: alfavaca, mentraste, terramicina, angelim, fedegoso. Medicinal species with AMU values higher than 25% were: Strychnos pseudoquina, Plectranthus barbatus, Citrus sinensis cv. pera, Cymbopogon citratus. There was a relationship between the number of useful plants and the residence time of the participants. The Bananal community revealed high species richness and the relationship of knowledge showed that the older the residents and the longer their residence time in the community, the more knowledge they acquired.

The diversity of useful plants and botanical knowledge of the Rejang Tribe in Kepahiang District, Bengkulu Province, Indonesia

“…The correlation was moderately strong, and statistically highly significant. The result of this study confirms the previous studies that showed the decline of local botanical knowledge among young generations, as happening in rural community of Bananal, Mato Grosso, Brazil (Miguéis et al 2019), in Garifuna, Nicaragua (Coe and Anderson 1996), in Western Himalaya (Uniyal et al 2006), in Sukamandi Village of Subang, West Java, (Suryana et al 2018), in Tanjung Terdana village, Central Bengkulu (Wiryono et al 2017), and Tebing Rambutan Village (Wiryono et al 2019). Indeed, the decline of botanical knowledge worldwide has become a serious concern among ethnobotanists worldwide (Ramirez 2007;Aswani et al 2018).…”

“…In Bustamante, in the northern region of the State of Nuevo León, Mexico, 218 useful species were recorded from private and public gardens which were employed for eight major uses (Estrada-Castillón et al 2018). The rural community of Bananal, Mato Grosso, Brazil, used 152 species from the natural vegetation and agricultural land for six major uses (Miguéis et al 2019).…”

Herbal Medicine Used in the Treatment of Human Diseases in the Rif, Northern Morocco

“…Generally, the main route of application for herbal therapies was oral (82.4%). Furthermore, the oral mode of administration is a preferred route all over the world [ 10 , 14 , 36 , 38 , 39 , 65 ]. The predominance of oral treatment may be explained by a large incidence of internal illnesses in the Rif region.…”

Plant-derived utility products: knowledge comparison across gender, age and education from a tribal landscape of western Himalaya

“…Male was coded as 1, female as 0 while for the age groups dummy variables D1, D2, D3 and D4 were used. We considered p values < 0.05 as statistically significant [39, 40] .…”
