Melt one to two 5ml spoonfuls of Vicks VapoRub into a bowl of hot water and then "Keep sufficient distance from the bowl to avoid burning of the face due to hot vapours". You can get teabags of this (the pricey Lemsip) or do it old school (Grandma style) and put a couple of slices of lemon in a mug of hot water and some honey. Night time baths with olbas oil bath.
