For the cough at night dry heat a knob of ginger while still hot wrap in a tea towel and rub it on your back until it goes cold. My mother uses that with me because I notroiously have bad coughs (though I have asthma to deal with to), but really it's a good tradtional method of controlling night time coughing. Or you can drink preserved lemon or kamquats if you happen to know and Asian who has the stuff, and this gets rid of the phlegm too. Too make it do no peel and lemon give a quick boil and let them cool then put some lemon in a jar then a layer of salt and continue until you've finished all the lemone leave for a few months until the lemon has turned brown it doesn't look good and it tastes horrible, but it again works. To prepare it for drinking get about a tablespoon of the stuff and mix with boiling water add a little honey just to cut the saltiness and drink.
