Abstract


Considering the importance of the evaluation of quality and performance attributes of herbal medicines, this work evaluated a gynecological gel containing aroeira (Schinus terebinthifolius Raddi), which was previously registered in 2001, and is still marketed in Brazil. Using the updated guides and legislation as a basis, the product was evaluated by checking the pH, spreadability, rheological behavior, in vitro release test, ex vivo permeation and retention study using porcine vaginal mucosa in Franz diffusion cells, and histological evaluation of the porcine vaginal mucosa before and after application of the product. After the permeation study, it was verified that gallic acid (chemical marker quantified) does not cross the mucosa, therefore, it is safe for local use. In addition, the pH of the formulation is within the range considered normal for use in healthy women. Finally, the histological evaluation of the mucosa showed changes compatible with the application of tannins (major compounds of the plant), and without changes indicative of loss of tissue integrity.
