Thyme Tea is very good to open up the breathing passages, it may even help dry out the liquid in the lungs. Foenugreek Tea is good as an expectorant to get the phlegm out. In fact eating food with Curry Powder is helpful (has Foenungreek in it) and will help you feel better too. I did this one time when I had Bronchitis really bad and it helped me get better.
Eat lots of Garlic of course.
Otherwise, maybe take at least a couple grams or so of Vitamin C at the opposite time of the day when you take the Miracle-Mineral-Supplement .
