The inflammation is a response to acute tissue injury responsible for producing characteristic symptoms that lead to changes in tissue homeostasis and blood flow, as a defense mechanism of the immune system. However, chronic inflammation is a cause of many diseases like cancer, arteriosclerosis, diabetes and neurodegenerative diseases. Most anti-inflammatory drugs exert significant side effects that may limit their use. An alternative to such drugs are the medicinal plants, which provide an important approach for the identification of bioactive compounds. This systematic review aimed to quantify the clinical studies that relate therapeutic potential for inflammatory diseases from the study of plants RENISUS, published between 2010 and February 2013 in three scientific databases (SciELO, Science Direct and Springer). Of the 21 357 articles found in databases, analysis of articles was originally made from the title of journal reading, the chosen articles were subsequently assessed for Abstract. Finally, Articles chosen at this stage, the full text was analyzed. This analysis resulted in the selection of 44 studies of interest, which dealt with 20 different plants RENISUS.
