Ethnopharmacological relevance
An extensive ethnopharmacological survey was carried out in the Peruvian Amazonian district of Loreto with informants of various cultural origins from the surroundings of Iquitos (capital city of Loreto) and from 15 isolated riverine Quechua communities of the Pastaza River. A close attention was paid to the medical c...
Ethnopharmacological relevance:
The plant species reported here are used in contemporary phytotherapies by native and neo-urban societies from the Iquitenian surroundings (district of Loreto, Peruvian Amazon) for ailments related to microbial infections. Inhabitants of various ethnic origins were interviewed and 81 selected extracts were evaluated...
Objetivo: Determinar el efecto antibacteriano del extracto de Stevia rebaudiana (S. rebaudiana) frente a Streptococcus sanguinis (S. sanguinis) y Actinomyces viscosus (A. viscosus). Métodos: Se desarrolló la prueba de sensibilidad en placa de agar con discos, para lo cual se cultivaron las cepas de S. sanguinis y A. viscosus en placas de agar tript...
Deforestation of primary forests in developing countries is unquestionable, particularly, in tropical regions like Peru. Even extractors already use flooded forests. Consequently, populations of plants of commercial value have declined, putting their genetic diversity at risk (FAO 1993: 10–30; Namkoong et al. 1996). In the Peruvian Amazon, this pro...

... Compounds from Peruvian medicinal plants have been evaluated for their antidiabetic [93], anticancer [94], antiviral [95], antibiotic [96], and antiparasitic activities [97]; however, most of the studies in the literature were in vitro performed over plants extracts, and little information about the potential of single compounds on these activities is described, while these promising results can be explained by synergistic interaction or multi-factorial effects between compounds present in the plant extracts studied [98]. While pharmacodynamic synergy involves multiple substances acting on various receptor targets to enhance the overall therapeutic effect, and pharmacokinetic synergy involves substances with little to no activity helping the main active principle to reach the target by improving bioavailability or by reducing metabolism and excretion, this type of assay can hide the true potential of single molecules activity between different constituents of plant extracts. ...

... Myrciaria dubia (Kunth) McVaugh, popularly known as camu-camu, is native to the Brazilian and Peruvian Amazon regions. This species' leaves and fruit peels are used in Brazilian traditional medicine to treat diarrhea, female diseases, and labyrinthitis [14], while in Peru, M. dubia leaves are used to treat colds and arthritis [15]. Moreover, M. dubia fruits are considered a natural source of antioxidants by their significant content of ascorbic acid and phenolic compounds. ...
... El análisis microbiológico se llevó a cabo mediante la técnica de difusión en discos (Kirby-Bauer), la cual ha sido empleada por la gran mayoría de autores en este tema ( 1,11,19,25 ). Esta técnica es frecuentemente utilizada y se basa en el uso de discos de papel esterilizados empapados con el extracto experimental o la solución control. ...
