“…The community exhibits poorly developed commercial infrastructure (only a butcher shop and bars are present in the community) and has a public telephone, electricity, and public transport to facilitate access to the downtown area. There are no paved streets, nor is there a water distribution or sewer system (Alencar et al, 2009(Alencar et al, , 2010Araújo et al, 2008;Lins-Neto et al, 2010;Santos et al, 2009).…”

Human beings have accumulated rich experience with natural resources over time, but such knowledge can be strongly infl uenced by several factors, such as age, sex and occupation. This study focuses on the infl uence of these factors on knowledge of medicinal plants in a rural community in northeastern Brazil. Data were collected through semi-structured interviews with 102 people, with the number of plants and uses cited studied for quantitative analysis. Through this research, it was possible to show that the social variables studied (age, sex and informants occupation) have contributed to the formation of different patterns of knowledge regarding medicinal resources. The results indicate that awareness of this dynamic is necessary for the proper implementation of projects where the goal is the sustainable use of natural resources (because it indicates the different levels of knowledge within a community), for studies intended to discover new drugs (because it indicates the peculiarities of certain groups), and for biodiversity conservation strategies.

“…A large proportion of the medicinal plants in traditional tropical pharmacopoeias are derived from secondary forests and anthropogenic zones; herbs tend to dominate among the species that are traditionally cited Caniago and Siebert 1998;Stepp and Moerman 2001;Voeks 1996Voeks , 2004Voeks and Leony, 2004). Explanations for these patterns have been proposed but are still debated (see, for example, Albuquerque and Lucena 2005;Alencar et al 2009;Almeida et al 2005;Araújo et al 2008;. Curiously, this subject has attracted only limited interest among ethnobotanists and ethnopharmacologists.…”

The Inclusion and Selection of Medicinal Plants in Traditional Pharmacopoeias—Evidence in Support of the Diversification Hypothesis

et al. 2009

The Inclusion and Selection of Medicinal Plants in Traditional Pharmacopoeias-Evidence in Support of the Diversification Hypothesis. An ethnobotanical study with phytochemical analyses was undertaken to examine the medicinal plants used by residents of a small rural community in northeastern Brazil. The present work tested two ideas that attempt to explain the inclusion and selection of medicinal plants in a given culture: the diversification hypothesis and the concept of versatility. The study involved 101 people and used semistructured interviews. A total of 61 plants were selected, including 25 exotic and 36 native species. Plants were classified according to their habit and analyzed for their phytochemical components. In addition, the relative importance (RI) of these plants was calculated, and a chemical diversity index (CDI) was created and applied to each of the species. Exotic and native plants were found to have significantly different occurrences of certain classes of compounds; this result supports the diversification hypothesis. It was therefore concluded that exotic plants are included in traditional pharmacopoeias to fill therapeutic vacancies that native plants cannot satisfy.

“…basic (documentation of traditional botanical knowledge) (Liengme, 1983;Bhat et al, 1990;Cheikhyoussef and Embashu, 2013); quantitative (evaluation of use-values, relative use-values, proportion of agreement, and preference ranking) (Phillips and Gentry, 1993a, b;Assogbadjo et al, 2011;Avocevou-Ayisso et al, 2011); experimental (assessment of benefits, hypothesis testing and prediction) (Soleri and Smith, 1995;Albuquerque, 2006;Alencar et al, 2009); and applied (practical application of ethnobotanical information in areas such as pharmaceutical prospecting and conservation biology) (Gustafson et al, 1992;Cox, 1994). However, six fields of study (botany, anthropology, ecology, ethnopharmacology, linguistics and economics) are recognized (Martin, 1995;Cotton, 1996).…”

This paper reviews the current state and future prospects of ethnobotany in Nigeria. A brief historical background is presented. Books and journals indexed by Scopus and Science Direct were reviewed. Direct search was also made on the official websites of journals specializing in ethnobotany and allied disciplines. The field of ethnobotany manifests in all facets of human activities and relates to cultural and sociological relevance of plants. Ethnobotanical data generated from historical, religious, literary, linguistic, and pharmacological viewpoints serve as useful information regarding indigenous food production, traditional agricultural systems, and source for the development of new medicines. Since the vast majority of ethnobotanical studies conducted in Nigeria center on indigenous medicines, collaborative efforts geared toward efficient health service delivery is essential. This must include accreditation or documentation of traditional healers and herbal medicine vendors as well as policies in drug regulation, quality assurance, and control. Ethical guidelines and equitable sharing of benefits gained from sale of active compounds from source locations should be instituted and implemented. Conservation of indigenous plant resources requires the integration of ethnobotanical knowledge into national development programmes. Curriculum development and inclusion of ethnobotany (as a distinct subject) in Nigerian schools will direct future investigations in this promising field.
