Bronchitis
"Used a number of times over the years and always found it to work better than anything. 250mg capsules (6), 2 to begin then 1 per day, 1 hour before, or 2hours after eating. Lots of coughing up phlegm but clears the chest so can breath properly.

Keep lots of tissues handy.

It ought to be available over the counter, as in some foreign countries."
