Mice were given i.v. injections of water solutions of ethanol extract of propolis (EEP) over a varying period of time. Some of the animals were sacrificed immediately following the last injection and some within 2--4 weeks after the last injections. Internal organ samples were taken and underwent a microscopic examination. Insignificant pathological changes in the liver were observed. These changes were transient and regressed within 2--4 weeks after the application of EEP.
