Eyebright (2015) - Eye Infection


A 2015 study investigated the chemical composition and anti-microbial capacity of an essential oil of eyebright (Euphrasia rostkoviana) - looking at micro-organisms that cause eye infections. The micro-organisms evaluated were:

  • Enterococcus faecalis
  • Escherichia coli
  • Klebsiella pneumoniae
  • Staphylococcus aureus
  • S. epidermidis
  • Pseudomonas aeruginosa
  • Candida albicans

The study was the first to access the chemical composition of eyebright essential oil, finding more than 70 constituents.

The essential oil was effective against all micro-organisms except Pseudomonas aeruginosa. The most effective activity was against gram-positive bacteria.
