The essential oils from 73 aromatic herb drugs entered on Korean official formularies were tested for antibioticresistance inhibitory effect. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combination were oils from Magnoliae Flos or Piperis longi Fructus ($25{\mu}g/mL$)-Am or Amx ($4{\mu}g/mL$).

Thirty six essential oils from herb drugs entered in Korean official formulary, which are frequently used in oriental region, were tested for antibiotic resistance inhibition. When the oils were combined with ampicillin (Am) or amoxicillin (Amx) they showed significant inhibitory effects on the growth of multi-drug resistant Staphylococcus aureus SA2 in considerably low concentration. The most effective combinations were oils from Acanthopanacis Cortex ($0.49{\mu}g/mL$) with Am and Cnidii Rhizoma and Lonicerae Flos (2.77 and $2.79{\mu}g/mL$, respectively) with Amx as shown in minimum resistance inhibitory concentrations.

The resistance inhibitory activities of 54 odorant mixtures (essential oil) from 41 Korean aromatic herbs were tested against multi-drug resistant Staphylococcus aureus SA2, which has resistances to 10 usual antibiotics including chloramphenicol. As results, combinations of 28 kinds of samples from 21 herbs and chloramphenicol have resistance inhibitory activities in dose dependent manner.
