The use of laxative and diuretic herbal drugs is an alternative therapy for many people looking for loosing weight with fewer side effects. The microbiological evaluation is an essential requirement for the quality assurance of products. This study aimed to evaluate the microbial quality of artichoke (Cynara scolymus L.), centella (Hydrocotile asiatica L.), fucus (Fucus vesiculosus L.), and Senna (Cassia acutifolia Delile) capsules and teas, by counting the total viable aerobic microorganisms and through tests for specified microorganisms. On the total viable aerobic microorganisms count, the teas analyzed were approved, because although they had a high microbial load, this was in accordance with the specifications, however 16.66% and 66.66% of the capsules analyzed were rejected because they presented higher amounts of bacteria and fungi, respectively. In relation to the tests for specified microorganisms, 76% of the samples (88% of the teas and 58% of the capsules) presented one or more than one type of microorganisms. Salmonella sp. was present in 33% of the samples, showing the unsatisfactory microbial quality of the products in the market. These results demonstrate the necessity of performing quality control both on herbal raw material and finished products, through a rigorous control and inspection, adopting regulatory and educational measures.
