The present paper analyzes the commercialization of a new medicinal specie in a public market in Rio de Janeiro, Brazil. During the years 2005-2006 semi-structured interviews were made with 15 herbalists. A free list of the most commercialized species (97) was made, and calculated the salience index in witch Eugenia rotundifolia presented a high value. Chrysobalanus icaco is known in the literature as sold as abajurú, and has hipoglicemient properties, proven by pharmacological research. The local population uses this species for these properties, however in the market in question, E. rotundifolia is almost exclusively sold with the same popular name and medicinal property. Until the present time, no pharmacological data exists for this specie. Both species are native and predominantly present in the coastal formations (restinga) of Rio de Janeiro. The attribution of the hipoglicemient property of E. rotundifolia may indicate a correlation, made by the herbalists, with the pharmacology of other Myrtaceae species. The lack of knowledge, erroneous field surveys and problems related with environmental monitoring may be involved with this process.
