If you have metholated spirits (sorry about the spelling), vinigar and water, you could make 3,2,1 it is where you put 3 tablespoons of spirits, 2 vinigar and 1 water in to a bowl and dip a bandanna or tea towel in it then wrap it around you son's neck. I've used it on my kids and all my families kids and it works everytime (DO NOT USE IF THERE IS A THROAT INFECTION INVOLVED), it help to get rid of the phleym in the throat.
