The study is hardly applicable to the real world, as the subjects spent 5 days in a sequestered setting, but they are negative enough to suggest that further study is needed in relation to this herb.
The only issue that I take with the whole study is the certainty of the scientists that their results are conclusive:
The results of this study indicate that extracts of E. angustifolia root, either alone or in combination, do not have clinically significant effects on infection with a rhinovirus or on the clinical illness that results from it.
Note: it proves that in a sequestered setting, with presumeably little physical activity.
Big difference between that setting, and the immunosuppresion drivers in the bodybuilding lifestyle.
