There's been recent news on broccoli being particularly effective at opening up air passages etc. Recommend 'dose' is 6 oz. daily - with 2X being even better. The articles just say 'prolonged' use - but has anyone seen any references as to when one might see some kind of results -- 3/4 of a pound every day - even if one likes broccoli - starts to be a bit much if one would have to go six months before noticing anything.
But two-three weeks would be nice. Of course, one would have to keep up some kind of regimen to maintain the effect.
