Abstract

Rural communities have repertoires of knowledge associated with the use of plants related to various social
and biological aspects. The objective of this study was to identify the diversity of use of food and medicinal
plants by the Brejal rural community in Rio de Janeiro state, Brazil. Ethnobotanical data was obtained using
the snowball technique and semi-structured interviews with 22 farmers. Species diversity and use-value indices
were calculated. Relationships among the numbers of plants cited, interviewee age, gender, and working time
in agriculture were investigated. We identified a high diversity index, comprising 185 species belonging
to 53 botanical families, notably Asteraceae, Lamiaceae, and Brassicaceae. The greatest use-values were
associated with exotic species. Leaves were the plant structures most utilized, and infusions the predominant
method of preparation. The prescriptions most commonly cited related to illnesses of the digestive system.
Men and women did not differ in terms of the numbers of species cited. We found no correlations between
the ages of the interviewees and their working time in agriculture. The uniformity of the number of citations
demonstrates the shared knowledge throughout the community, covering a high diversity of plants, uses,
indications and preparations.

Key words: ethnobotany, food plants, local knowledge, medicinal plants, social-ecological variables.




Resumo

As comunidades rurais possuem um repert&#xF3;rio de conhecimentos associados ao uso de plantas que se relacionam
com diversos aspectos biol&#xF3;gicos e sociais. O objetivo deste estudo foi identificar a diversidade do uso de
plantas aliment&#xED;cias e medicinais pela comunidade rural do Brejal no estado do Rio de Janeiro, Brasil. Os
dados etnobot&#xE2;nicos foram obtidos por meio da t&#xE9;cnica &#x201C;Snow ball&#x201D; e entrevistas semiestruturadas com 22
agricultores. A diversidade de esp&#xE9;cies e &#xED;ndices de valor de uso foram calculados. Foram investigadas as
rela&#xE7;&#xF5;es entre o n&#xFA;mero de plantas citadas, idade dos entrevistados, g&#xEA;nero e tempo de trabalho na agricultura.
Identificamos um alto &#xED;ndice de diversidade, compreendendo 185 esp&#xE9;cies pertencentes a 53 fam&#xED;lias
bot&#xE2;nicas, destacando Asteraceae, Lamiaceae e Brassicaceae. Os maiores valores de uso foram associados a
esp&#xE9;cies ex&#xF3;ticas. As folhas foram as estruturas vegetais mais utilizadas e as infus&#xF5;es o m&#xE9;todo de preparo
predominante. As prescri&#xE7;&#xF5;es mais citadas s&#xE3;o relacionadas a doen&#xE7;as do sistema digestivo. Homens e mulheres
n&#xE3;o diferiram em termos do n&#xFA;mero de esp&#xE9;cies &#xFA;teis citadas. N&#xE3;o encontramos correla&#xE7;&#xE3;o entre a idade
dos entrevistados e o tempo de trabalho na agricultura. A uniformidade do n&#xFA;mero de cita&#xE7;&#xF5;es demonstra o
conhecimento compartilhado por toda a comunidade, abrangendo uma grande diversidade de plantas, usos,
indica&#xE7;&#xF5;es e prepara&#xE7;&#xF5;es.
