aiming to evaluate the quality of products made from medicinal plants, there were analyzed ten samples of horsechestnut, eleven samples of lemongrass, and six samples of gotu kola commercialized in pharmacies from the city of recife (pernambuco, brazil), coming from industries of several parts of the country. we analyzed the technical-scientific information on the labels and/or directions according to the requirements and obligations of brazilian law (laws %26quot;rdc 140 of 29/05/2003%26quot; and %26quot;rdc 102 of 30/11/2000%26quot;) and to scientific literature embasement. the products%26apos; organoleptic characteristics, authenticity, and purity were also evaluated. the absence of obligatory information was verified in 92.59% of the samples. among the blacked terms, it was common to find products that suggested inexistent collateral or adverse effects. technical terms were not standardized and the manufacturers did not provide scientific proof for some of the activities credited to the products. all samples were considered authentic based on the phytochemical and pharmacobotanical tests. the purity analysis considered 59.26% of the samples inappropriate, mainly due to the high total levels of humidity and ashes. it was verified that besides the lack of adequate information and quality of the commercialized products, there is an urgent need for an effective inspection by the suitable agencies.
