Abstract EN
Objective.
To identify whether a standardised Echinacea formulation is effective in the prevention of respiratory and other symptoms associated with long-haul flights.
Methods.
175 adults participated in a randomised, double-blind placebo-controlled trial travelling back from Australia to America, Europe, or Africa for a period of 1–5 weeks on commercial flights via economy class.
Participants took Echinacea (root extract, standardised to 4.4 mg alkylamides) or placebo tablets.
Participants were surveyed before, immediately after travel, and at 4 weeks after travel regarding upper respiratory symptoms and travel-related quality of life.
Results.
Respiratory symptoms for both groups increased significantly during travel (P<0.0005).
However, the Echinacea group had borderline significantly lower respiratory symptom scores compared to placebo (P=0.05) during travel.
Conclusions.
Supplementation with standardised Echinacea tablets, if taken before and during travel, may have preventive effects against the development of respiratory symptoms during travel involving long-haul flights.
