O presente trabalho consiste diagnÃstico de plantas com usos terapÃuticos e caracterizaÃÃo do perfil de comunidades sobre a conservaÃÃo da flora nativa do entorno da Reserva Natural Serra das Almas, CE e PI, Brasil. Para isto, investigou-se diversos aspectos como:o perfil sÃcio-econÃmico-cultural das comunidades; o repasse do conhecimento etnobotÃnico entre as sucessivas geraÃÃes; as informaÃÃes etnobotÃnicas relativas ao uso das plantas medicinais, dados relativos ao perfil epidemiolÃgico das comunidades; o comÃrcio de plantas em Ãrea urbana; e sobre a existÃncia de uma preocupaÃÃo do ponto de vista conservacionista com a flora local. Foram aplicados diferentes tipos de questionÃrios semi-estruturados para os grupos populacionais selecionados: 1) parteiras, curandeiros e raizeiros, 2) pÃblico jovem de 15 a 25 anos, 3) funcionÃrios dos postos de saÃde do entorno da reserva, 4) comerciantes de plantas medicinais da feira livre da sede municipal de CrateÃs. Paralelamente a essas entrevistas, foi realizado o levantamento florÃstico das espÃcies cultivadas nos quintais e na vegetaÃÃo perifÃrica Ãs residÃncias. Efetuou-se ainda, o cÃlculo do âValor de Usoâ das plantas usadas como medicinais, a fim de medir o grau de importÃncia de cada uma, para as populaÃÃes das comunidades analisadas. Foram citadas 61 espÃcies medicinais, pertencentes a 36 famÃlias, das quais, por falta de material botÃnico em estado reprodutivo, 27 sà foram identificadas em nÃvel de gÃnero. As famÃlias e subfamÃlias com maior nÃmero de espÃcies mencionadas foram: Lamiaceae (8), seguida por Euphorbiaceae (5), Anacardiaceae e Leg-Caesalpinioideae (4), Leg-Faboideae e Verbenaceae (3), Apocynaceae, Bignoniaceae, Moraceae e Olacaceae com 2 espÃcies cada. As plantas medicinais citadas sÃo utilizadas principalmente para o tratamento das gripes, a qual constitui tambÃm a enfermidade mais freqÃente detectada nos postos de saÃde. Verificou tambÃm que as folhas foram as partes da planta mais usadas pelos entrevistados. Algumas espÃcies se destacaram pelo elevado valor de uso como: Plectranthus amboinicus (Lour.) Spreg (2,50), Himatanthus sp. (2,50), Ocimum gratissimum L. (2,00), Caesalpinia ferrea Mart (2,00), Licania rigida Benth (2,00). Os resultados demonstraram uma tendÃncia à perda do conhecimento etnobotÃnico entre os jovens. / The present study has subject out a diagnostic of therapeutic-use plants and characterization profile of the communities about conservation of the native flora at the region of Reserva Natural Serra das Almas, CE and PI, in Brazil. In order to do that, different pieces of information were investigated, such as the social-economical-cultural profile of the communities; the spread of ethnobotanical knowledge among successive generations; the ethnobotanical information of medicinal plants, data related to the epidemiological profile of the communities, to the trade of plants in urban areas, and on the existence of concern â on the conservationist point of view â about the local flora. Diferents types of halfstructured of questionary were carried to the populations of elect groups: 1) midwife, rootmen, witchdoctor, 2) young public of 15 to 25 years old, 3) servant of half post at the region of Reserva, 4) the businessman of medicinal plants to the free market of CrateÃs. Parallel of this interview, take effecting floristical survey of the species cultivated in the back yard and in the outskirts vegetation. The calculation of the âvalue of useâ of the medicinal plants was also carried out - in order to measure the level of importance of each plant to the communities of the studied areas. About the local flora were also researched. 61 medicinal species were cited, that to belong to 36 families, of which just 27 have been identified in genus level, because didnât have botanic material in a reproductive condition. The families with the largest number of mentioned species were: Lamiaceae (8), following Euphorbiaceae (5), Anacardiaceae and Leg-Caesalpinioideae (4), Leg-Faboideae e Verbenaceae (3), Apocynaceae, Bignoniaceae, Moraceae, Olacaceae with 2 species each.. Medicinal plants are mainly used for the treatment of the flu, which is also the most frequently detected illness at health centers. Verified yet, that the largest part of plant used were the leaf. Some species have stood out for their high value of use, such as Plectranthus amboinicus (Lour.) Spreg (2,50), Himatanthus sp. (2,50), Ocimum gratissimum L. (2,00), Caesalpinia ferrea Mart (2,00), Licania rigida Benth (2,00). The results have shown a tendency towards the loss of ethnobotanical knowledge within young people.
