Los cosméticos son productos de venta libre y de uso diario para los consumidores, quienes restan importancia a las implicaciones de salud que pueden experimentar a causa de los mismos. Es necesario monitorear la postcomercialización de estos productos, ya que en los años recientes se han visto asociados a reacciones adversas; de esta manera nace el concepto de cosmetovigilancia y la necesidad de implementar sistemas para llevarla a cabo. Esta revisión sistemática encontró un limitado número de publicaciones que informen del estado actual y de las tendencias de la cosmetovigilancia, aunque fue posible definir el concepto e identificar los países que lo han desarrollado e implementado, siendo la Unión Europea quien lidera estos aspectos, contando con la participación de distribuidores, industrias, profesionales de la salud y consumidores. La cosmetovigilancia es un campo de la vigilancia sanitaria que se encuentra aún en desarrollo y por lo tanto, es importante continuar con la indagación al respecto, hasta lograr un mecanismo de vigilancia eficiente y útil tanto para los países miembros de la Unión Europea, como para aquellos que aún se encuentran en vías de desarrollo, como Colombia.

Cosmetics are free sale products that are used daily by consumers who usually not concerned about the possible health implications by the use of these products. It is necessary to perform a post-sale monitoring for these products, since in recent years they have been associated with adverse reactions. For this reason was built the cosmetovigilance concept as well as the need to implement a system to perform this task. This systematic review found a limited number of publications about the current cosmetovigilance status and tendencies at world level. Nevertheless, it was possible to define the concept and identify the countries that have developed and implemented this system. European Union is the leader in this topic, with investigations, regulations, development and implementation of an harmonized cosmetovigilance system. These activities include the participation of distributors, manufacturing industries, health professionals and consumers. Cosmetovigilance is a sanitary vigilance area that is still under development and therefore it is important to keep on investigating about this topic until achieve an efficient and useful system, for both European Union members and developing countries such as Colombia.

Os extratos etanólicos de folhas de guaco (Mikania laevigata) cultivado tradicionalmente no solo ou por hidroponia foram avaliados quanto às atividades alelopática e antimicrobiana. Para a atividade alelopática foi utilizado o ensaio de inibição da germinação de sementes de alface (Lactuca sativa), enquanto que para a atividade antimicrobiana utilizouse a técnica de difusão em disco. Observou-se um notável efeito alelopático dos extratos de ambos os cultivos, em especial do extrato etanólico do guaco tradicional, que mesmo na menor concentração testada inibiu completamente a germinação das sementes. Nenhum dos extratos etanólicos do guaco apresentou atividade antibacteriana significativa para as linhagens de Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis e Enterococcus faecium.

The ethanolic extract of "guaco" (Mikania laevigata) traditionally cultivated in the soil or in a hydroponic system were tested for allelopathic and antimicrobial activities. Allelopathic activity was evaluated by the inhibition of germination assay using lettuce seeds, and antimicrobial activity by the disc diffusion assay. A notable allelopathic effect was observed for both extracts, although a more expressive activity of traditional "guaco" was verified, since the inhibition of seeds germination was 100% even in the lower concentration. None ethanolic extract of "guaco" presented significant antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis and Enterococcus faecium.
