as a person with chronic bronchitis since birth I can say the ONLY thing (outside of narcotic cough meds) that even comes close to helping me is homemade lemon/honey tea
1 lemon
2 cups of water
honey
sugar
cut the lemon in half and squeeze them into a small saucepan then cut up the rinds of one have into big hunks and put them in the pan, cover with about 1/2 cup honey (add more or less according to your taste...I like more than that) so the same with the sugar, add two cups of water and cook over medium heat stirring until mixed well and sugar is melted, then bring it to a boil, pour into a cup with a few of the rinds and drink
