The aim of these work was to determinate presence of contaminants in chamomile (Matricaria chamomilla) and juanilama (Lippia alba) commercialized in the municipal markets in San José, Heredia and Cartago, Costa Rica. They were collected samples of chamomile and juanilama in different sale points within the Cartago, Heredia and San José markets. The samples were analyzed fresh and through the criteria established by WHO; for the quality control of herbal products, the quantification of materials foreign to the traded product was established: insects, mixtures of soil minerals, plastic, glass and mold.
