An experimental double-blind study to evaluate the use of Euphrasia in preventing conjunctivitis

Abstract

A double-blind study using Euphrasia 30c or placebo was carried out during an epidemic of viral conjunctivitis. Nine hundred and ninety-four subjects were available at follow-up, when 48 subjects in the group given Euphrasia and 43 subjects in the placebo group had signs and symptoms of conjunctivitis, a difference which was not statistically significant. The protocol by which Euphrasia was tried may be used without change to scientifically confirm the efficacy of a genus epidemicus. The concept of genus epidemicus lends itself well to experimental double-blind studies in homœopathy during epidemics.
