Species of Origanum L. (Lamiaceae) are traded in Argentina mainly as flavorings. With the aim of evaluating the quality in "oreganos", a random sampling of twelve trademarks commercialized in Buenos Aires City was performed. The packaging and organoleptic characters of the samples were examined; the components were separated under stereomicroscope and calculated the percentages. Subsequently, a microscopic analysis by obtaining and observing macerations was undertaken. The studies conducted revealed the presence of foreign matter mainly composed of own stems and bran cereal in some samples. The percentages found were higher than those suggested by the Argentinean Food Codex. We conclude that the foreign matter causes a reduction in the plant parts used, introduces adulterants and negatively affects the quality of the product. The methodolgy used in this study contributes to a better control over the "oregano" for trade.
