ABSTRACT
Since essential oils are subject for pharmacological studies, tests on their antimicrobial activities have been done frequently. In consequence, a comprehensive data material exists, which, however, has never been compiled together for important essential oils, like such listed actually in the European Pharmacopoeia. Therefore, an attempt was done to collect and examine such information from scientic literature to obtain an insight into the variability of test parameters, data variation, and the signicance of such factors in the interpretation of results.
