Background: In spite of an increasing number of ethnobotanical market surveys in the past decades, few studies compare changes in plant species trade over time. The open-air market Ver-o-Peso (VOP) in Belém, located near the mouth of the Amazon River in the state of Pará, Brazil, is known for its wide variety of medicinal plants. A survey of VOP was published in 1984, but it remains unknown to what extent its botanical composition changed over 34 years. Furthermore, in northern Brazil, little attention has been given to the origins of the vernacular names of these plants. Our aim is to give an up-to-date overview of the VOP medicinal plant market, concentrating on changes in species composition and vernacular names over time. Methods: We collected medicinal plants and vernacular names at VOP in August 2018. We identified most plants at the Museo Paraense Emilio Goeldi Herbarium, where we also deposited vouchers and specimen labels. We compared our species composition data to the 1984 inventory by Van den Berg. Furthermore, we investigated the etymologies of the vernacular plant names. Results: We recorded 155 plant specimens and 165 corresponding vernacular names, and collected 146 specimens from the medicinal and ritual stalls of VOP reporting 86 species formerly not recorded at this market. Vernacular names had mostly Portuguese roots, followed by Tupi and African ones. We found 30 species also documented in 1984, and vernacular names that overlapped between both surveys were used for the same botanical species or genus, indicating that vernacular names have changed little in the past decades. Lastly, we found 26 more introduced species sold at VOP compared to 1984. Conclusions: Forest degradation and deforestation, prevalence of diseases, and methodological factors may play a role in the differences we found in our survey compared to 1984. Of the plants that did overlap between the two surveys, vernacular names of these plants were hardly different. Lastly, the lingual origins of the vernacular names in our survey and the origins of the plant species reflect the history of the intricate syncretism of medicinal plant practices of indigenous, Afro-Brazilian and European origins in Belém.
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.

Given the importance of markets and fairs for the commerce of medicinal plants, an ethnobotanical study was undertaken at the Caruaru Fair (Pernambuco, northeastern Brazil) to compare the richness of species sold and their values of relative importance (RI) using two datasets collected with a 4-year interval. The seasonality of these plants' supplies was also analyzed. The Caruaru Fair is located in the 18 de Maio Park. It covers an area 40,000 m 2 and is used by merchants who sell several types of products, such as supplies, handicrafts, clay and aluminum utensils, shoes, clothes and medicinal plants. Semistructured interviews were carried out with the vendors who agreed to take part in the study in order to record which plants were sold and their respective indications. The plants were collected, and the species were determined. The information was analyzed with quantitative tools. A total of 169 plants were identified from both surveys, which were significantly different with regard to species richness ( p < 0.05) but did not vary in relation to species' Relative Importance ( p > 0.05). In relation to the seasonality of the plant supply, habit may explain the lack of some species during certain periods of the year, as most of the absent plants are herbaceous. In terms of the species most sold locally, it was found that spontaneous tree species are well known and extensively commercialized.
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
Does the selection of medicinal plants by Brazilian local populations suffer taxonomic influence?
Journal of Ethnopharmacology, 2013
Ethnopharmacological relevance: Although the relationship between local people and plants may be idiosyncratic, some human behaviors are common to different communities and can be influenced by cultural and environmental factors. Thus, this study drew upon a systematic review and meta-analysis to evaluate if there are patterns of medicinal plant use in different Brazilian ethnobotanical studies and if these patterns are influenced by the urbanization or ecosystems where the studies were conducted. Materials and methods: The factors evaluated concerned the origin of the species used (native vs. exotic), plant habit (woody vs. non-woody) and plant parts (permanent and non-permanent). Two kinds of analysis were performed: the integrative and the meta-analytical. Results: The factors varied depending on the ecosystems in which the studies were conducted. In the Amazon, Cerrado and Caatinga, native and woody medicinal species dominated; conversely, this pattern was not the case for the Atlantic Forest and Pampas ecosystems. Permanent plant parts were predominant in the Cerrado, and considering only native plants, permanent parts dominated in the Amazon, Cerrado and Caatinga. Urbanization did not significantly affect these patterns. Additionally, the species relative importance (RI) did not change as a function of the ecosystem or the degree of urbanization. Conclusions: The phenomena observed in this study can be explained in light of the chemical ecology and historical and cultural aspects of the species, and the findings have important implications for bioprospecting and conservation.

Background: Ethnobotanical research has demonstrated that several wild food plants (WFP) are used for medicinal purposes. Therefore, in addition to constituting an important source of nutrients, WFP can be used to help treat and avoid health problems. This study sought to characterize the traditional use of plants considered simultaneously as food and medicine by local specialists in the community of Caeté-Açu, which borders Chapada Diamantina National Park (NE Brazil). We also sought to identify the drivers of species’ cultural importance. Methods: We selected local specialists based on a snowball sample and used a free-listing technique to register the wild plants they knew that are both edible and medicinal. Then, we asked the specialists to rank each plant component cited according to the following attributes: (1) ease of acquisition, (2) taste, (3) smell, (4) nutritional value, and (5) medicinal value. We used multiple regression to determine the drivers of popularity and frequ...

Ethnopharmacological relevance: Parallelisms between current and historical medicinal practices as described in the seventeenth century treatise Historia Naturalis Brasiliae (HNB) provide us with an overview of traditional plant knowledge transformations. Local markets reflect the actual plant use in urban and rural surroundings, allowing us to trace cross-century similarities of ethnobotanical knowledge. Aims of the study: We aim to verify in how far the HNB, created in seventeenth-century northeastern Brazil, correlates with contemporary plant use in the country by comparing the plant knowledge therein with recent plant market surveys at national level. Materials and methods: We conducted a literature review on ethnobotanical market surveys in Brazil. We used the retrieved data on plant composition and vernacular names, together with our own fieldwork from the Ver-o-Peso market in Belém, to compare each market repertoire with the useful species in the HNB. We analyzed similarities among markets and the HNB with a Detrended Correspondence Analysis and by creating Venn diagrams. We analyzed the methods of the different markets to check whether they influenced our results. Results: Out of the 24 markets reviewed, the greatest similarities with the HNB are seen in northern Brazilian markets, both in plant composition and vernacular names, followed by the northeast. The least overlap is found with markets in the central west and Rio de Janeiro. Most of the shared vernacular names with the HNB belonged to languages of the Tupi linguistic family. Conclusion: The similarity patterns in floristic composition among Brazilian markets and the HNB indicate the current wider distribution and trade of the species that Marcgrave and Piso described in 1648 in the northeast. Migration of indigenous groups, environmental changes, globalized and homogenous plant trade, and different market survey methods played a role in these results. The HNB is a reference point in time that captures a moment of colonial cultural transformations.
Local Markets and Medicinal Plant Commerce: A Review with Emphasis on Brazil
Economic Botany, 2010
Local Markets and Medicinal Plant Commerce: A Review with Emphasis on Brazil. Local markets unite, concentrate, maintain, and diffuse empirical knowledge about plant and animal resources and therefore help guarantee the resilience and maintenance of folk knowledge concerning useful species. A critical review is presented here that focuses on the importance of these local markets, emphasizing the diversity of medicinal products offered, the different approaches to this subject, and the evolution of the research approaches taken in studying the medicinal plant products sold. To this end, the scientific literature was examined for research on these markets so as to provide a panoramic view of the different approaches taken, the diversity of plants being sold, the methodological procedures employed in collecting research information, and the specific nature of the studies. From our point of view, it is necessary to intensify the ethnobotanical and ethnopharmacological investigation of these markets, especially with comparable methods and techniques. Mercados locais e o comércio de plantas medicinais: Uma revisão com ênfase no Brasil. Os mercados tradicionais são importantes por reunir, concentrar, manter e difundir o saber empírico sobre a diversidade de recursos tanto da fauna como da flora, sendo fontes imprescindíveis para a resiliência e manutenção do conhecimento acerca dessas espécies medicinais. Essa proposta de revisão crítica enfocou a importância desses centros de compras, ressaltando a diversidade de produtos ofertados, os diferentes enfoques das pesquisas realizadas e a evolução das abordagens ao estudar os produtos vegetais comercializados nos mercados. Dessa forma, realizou-se uma busca em periódicos para evidenciar o desenvolvimento das pesquisas com mercados intencionando-se uma visão panorâmica das diferentes abordagens utilizadas. Sobre isso, foram abordados: a diversidade vegetal comercializada, as partes vegetais mais encontradas nos mercados, bem como os procedimentos metodológicos para coleta de informações e a natureza desses estudos. A partir das análises realizadas, recomendações foram sugeridas para futuras pesquisas em mercados tradicionais: a realização de inventários locais sobre espécies úteis associado a comparações com informações já existentes.
