Echinacea used in children or adults has been investigated in a significant number of studies and has not been shown to be effective in lessening cold symptoms or shortening the length of illness.

So this potential benefit may be less than reported.
Certainly, Echinacea is not a major cornerstone of improving immunity against infections, but can be used preventively through the winter cold and flu season.
