The pdf link at the webpage above was not accessible, but I found an objective-sounding summary here:  (because full article was unavailable, unable to assess strengths and limitations of analysis and study design)

  • Randomized clinical trial (RCT) examining the effect of elderberry vs. placebo lozenges in reducing influenza symptoms.
  • N=32
  • In subjects taking elderberry, in comparison to their symptoms at baseline, there was a statistically significant reduction in headache, nasal congestion, and fever after 48 hours.
  • Subjects taking placebo actually showed a worsening in nasal congestion and headache after 48 hours.
  • All subjects taking elderberry eventually had no fever.
  • While there was no statistically significant reduction in cough compared to baseline in elderberry or placebo, the severity of cough in subjects taking elderberry was statistically lower compared to placebo.
  • No adverse effects were seen.

Keywords: RCT, influenza, symptom improvement
