Study: Coriander and thyme essential oils for vaginal infections

Coriander Thyme essential oil douche

This study looked at coriander and thyme essential oils for the gynaecological treatment of microbial and fungal infections.

Essential oils studied

  • Coriandrum sativum L. essential oil
  • Thymus vulgaris L. essential oil

Bacteria and fungi studied


  1. Bactericidal activity was higher for coriander EO against almost all tested bacteria, except multiple resistant strains of Enterococcus sp. and Proteus sp.
  2. Thyme EO showed slightly better fungicidal activity for all C. albicans strains.
  3. The effect of EOs on biofilm-forming ability was tested for two strains of Staph. aureus and E. coli, as well as on C. albicans filamentation ability.

Study conclusions
In-vitro, coriander essential oil can be used against E.coli, Staph. aureus and C. albicans vaginal infections as an alternative gynaecological treatment.
