According to Zirihi et al. (2005), an extract is considered safe when EC50 is >20 µg/mL. As shown in Table I, T. crispa extract and P. guajava extract as well as the eight fractions obtained from T. crispa crude extract and clindamycin (as positive control) showed no cytotoxicity against Vero cells.	cache/bjp-12499.pdf	txt/bjp-12499.txt
