The first Rapid Color Guide of “Plants traditionally used to treat Malaria (and related conditions) 100 species from the ethnobotanical literature (Guide #367)”, was published online in January 2015. This work was conducted by the Plant Chemicals Research Network for Malaria Control based on ethnopharmacology research in the Brazilian states of Amazonas and Acre. Work was funded by Brazil’s National Council for Scientific and Technological Development (CNPq). Malaria still kills a huge number of people each year and this disease is therefore a major global health problem. This has motivated the development of research into new alternatives for the control and cure of this disease, which is the main objective of this research network. This guide is the result of an extensive literature survey conducted between 2010 and 2012 using scientific reference sites (SciFinder Scholar, Scielo, PubMed, Science Direct ISI Web of Science) as well as public and private libraries of research institutes and herbal, public and private libraries of research institutes and herbaria. Locations where photos were taken include: the botanical garden of the University of Amazonia (UNIAMAZONIA-Colombia); the "José Celestino Mutis" Botanical garden in Colombia, Kew Gardens (United Kingdom); The National Institute for Research in the Amazon (INPA-Brazil) as well as in other localities and local markets in the Brazilian and Colombian Amazon. This six page guide was organized by Gina Frausin, Renata Lima, Ari Hidalgo, Lin Chau Ming & Adrian Pohlit and assisted by the Action Center’s Juliana Philipp, Tatzyana Wachter, and Robin Foster, with support from Trustee Connie Keller, the Ellen Hyndman Fund, and the Mellon Foundation.
