The study of medicinal plants is currently one of the alternative sources of allopathic medicine for therapeutic purposes. Given the high consumption of medicinal plants and the risks of indiscriminate use, the objective of the study was the identification of potential plant-drug interactions in the pharmacotherapy of the Public Health System users in a Brazilian Northeastern city, from 2015 to 2017 regarding the plant species used, as well as their therapeutic properties. An ethnobotanical study was conducted with a questionnaire. For this purpose, 46 types of plants were used by the 402 interviewees, where 297 were women, with 279 adult participants, and 269 medicinal plants used. Only 199 people out of the total interviewed used some medication, of which 55 associated the use of the drug with medicinal plants. We analyzed associations between the use of 13 plants and 27 drugs, totaling 42 potential interactions. Lemon balm was the vegetal species that presented the most common interactions among the interviewees. Thus, it was possible to conclude that medicinal plants are quite used for therapeutic purposes. However, one must be cautious about its use since they can interact with drugs, reducing or potentiating their effects.

RESUMO: "Plantas medicinais e outros produtos vegetais da Farmacopéia Brasileira". Este artigo descreve os resultados de uma extensa revisão efetuada nas quatro edições da Farmacopéia Brasileira, buscando dados sobre as plantas medicinais e outros produtos vegetais nela descritos. O crescimento da indústria farmacêutica internacional a partir da segunda metade do século passado afetou intensamente a medicina ofi cial no Brasil. O texto faz uma breve análise das transformações sofridas pela Farmacopéia, tomando como base a existência de Monografi as para as espécies vegetais nativas. Os resultados do estudo demonstram uma intensa substituição das plantas nativas do Brasil por medicamentos industrializados e outros produtos vegetais estrangeiros, confi rmando assim a necessidade de investimentos em pesquisa de validação das nossas plantas medicinais.
Ethnopharmacological importance: The use of medicinal plants for treatment, cure and prevention of diseases has been described by many people since time immemorial. Because of this use, commercial and scientific interests have emerged, making it necessary to realize ethnobotanical surveys of medicinal plants species, which is important for subsequent chemical and pharmacological bioprospections. Aim of the study: This study aimed at surveying, identifying, cataloging and documenting the medicinal plants species used in the Valley of Juruena, Northwestern Mato Grosso, Legal Amazon Brazil for the treatment of various human diseases, as well as assessed the species of interest for bioprospecting potential. Materials and methods: Informants were interviewed using semi-structured form to capture information on socio-demographic and ethnopharmacological data of medicinal plants such as vernacular name, uses, geographic origin, habit, form of preparation and part used. Results were analyzed using descriptive and quantitative means: indices of use-report (Ur) and informant consensus factor (ICF), for the selection of plant species with therapeutic potential. Results: Three hundred and thirty two plants species belonging to 90 families were reported for medicinal purposes and totaling 3973 use-reports were reported by 365 (92.9%) of the people interviewed. Asteraceae (32.2%), Fabaceae (26.7%) and Lamiaceae (24.4%) families were the most represented, with majority being species native (64.45%) to Brazil. Leaves (64.5%) were the part of the plant most used and infusion (45.7%) was the most utilized form. Gastrointestinal disorders followed by respiratory complaints topped the list of use-reports. The native or naturalized plants with the highest use reports in the order of decreasing absolute frequency per each emic-category are Cymbopogon citratus (DC.) Stapfc (104), Mentha pulegium L. (94), Arrabidaea chica (Humb. & Bonpl.) B. Verl. (97), Alternanthera brasiliana (L.) Kuntze (71), Baccharis crispa Spreng (57), Phyllanthus niruri L. (48), Gossypium barbadense L. (44), Solidago microglossa DC. (40) and Bauhinia forficata L. (20). And the most cited exotics are: Chenopodium ambrosioides L. (151), Aloe vera (L.) Burm. f., (89) and Rosmarinus officinalis L. (72). In some cases, high ICF values were found, which reflects high degree of homogeneity of consensus among informants in this region on medicinal plants. Conclusion: The population of Valle of Juruena makes use of a wide array of medicinal plants distributed in all use categories with predominance of those use in the treatments of gastrointestinal and respiratory Contents lists available at ScienceDirect

Medicinal and magic plants from a public market in northeastern Brazil
Journal of Ethnopharmacology, 2007
Markets are public spaces in which many kinds of products are sold, as well as places of cultural information exchange. These spaces are distinctive for each given culture or society as they represent small-scale reproductions of that region's cultural and biological diversity. We carried out ethnobotanical studies in an important traditional market in the city of Recife (Pernambuco, northeastern Brazil) in two distinct years, 1995 and 2002. Our objectives were to compare the taxonomic richness of the plants being sold there in these different years, to investigate differences between the species' relative importance, and to present descriptions of their main uses. Considering the lack of ethnobotanical studies in these markets and the great methodological difficulties in gaining access to this type of information, we discuss the limitations of this kind of study and offer suggestions to deal with specific problems. Semi-structured interviews with the plant vendors were carried out in the market, along with other data-collection and analysis techniques common to ethnobotanical studies. A total of 136 species were recorded -an increase of 58 species between the two study periods -with significant differences among the proportions of families, genera, and species (p < 0.05). Despite differences in the relative importance of species found in both surveys, there was an underlying trend maintaining the same species of greatest importance. Our data suggest that markets conserve their basic repertoire while at the same time act as open and dynamic systems that is enriched by adding new plants and their respective use-indications.
Changes in the trade in native medicinal plants in Brazilian public markets
Plants continue to be an important source of new bioactive substances. Brazil is one of the world's mega-diverse countries, with 20 % of the world's flora. However, the accelerated destruction of botanically rich ecosystems has contributed to a gradual loss of native medicinal species. In previous study, we have observed a fast and intensive change in trade of medicinal plants in an area of Amazon, where human occupation took place. In this study, we surveyed 15 public markets in different parts of Brazil in search of samples of 40 plants used in traditional medicine and present in first edition of Brazilian Official Pharmacopoeia (FBRAS), published in 1926. Samples of plants commercialized as the same vernacular name as in Pharmacopoeia were acquired and submitted to analysis for authentication. A total of 252 plant samples were purchased, but the laboratory analyses showed that only onehalf of the samples (126, 50.2 %) were confirmed as the same plant species so named in FBRAS. The high number of unauthenticated samples demonstrates a loss of knowledge of the original native species. The proximity of the market from areas in which the plant occurs does not guarantee that trade of false samples occurs. The impact of the commerce of the substitute species on their conservation and in public health is worrying. Strategies are necessary to promote the better use and conservation of this rich heritage offered by Brazilian biodiversity.
