Ricola cough drops and hot decaf mint herbal tea (with honey if you have a cough – personally i prefer the taste sans honey).
I like the ricola honey lemon drops the best – for whatever reason the herbs in the drops just open up my sinuses completely. any flavor should do – and in theory other brands of cough drops that have menthol flavoring also would probably work – but ricola IMO is definitely the best and you cant overdo it.
also – sinus rinse. ive found the neti pot (it looks like a blue version of the genie lamp from the movie alladin) to not work for me, instead i use a positive pressure version, i think its called sinus rinse? its a clear bottle with a black cap and it comes with special salt packets. you can find it at drugstores for $10-15. i rinse the nose piece with rubbing alcohol between colds/infections to keep it sanitary.
also – hydrogen peroxide 3% (most commonly found in drugstores and supermarkets) – i put about a capful in my ear, with head tilted almost horizontal, and let it sit for a few minutes until i head a whoooooosh. youll hear bubbling and popping, it might be a little uncomfortable but harmless and not painful. repeat with the other ear. dont overdo it though – H2O2 is bad for your skin, it kills good cells and in stronger forms acts as a bleach. i do this after the sinus rinse – the positive pressure tends to clog my ears, somehow this equalizes the pressure and relieves the sinuses overall.
vitamin C in very large doses (i take emergen-c drink mix twice a day – i like the raspberry flavor), and zinc 50mg twice a day.
and in general, spicy food. avoid dairy products – they increase mucus production.
and last but not least, 12 or 24hr sudafed behind the counter at the drugstore – the one that contains pseudophedrine HCI (not the over the counter kind – it does not work!). in the US you have to show ID to purchase it – people use it as an ingredient in making meth. don’t take vitamin C when taking sudafed, it lessens the potency of the sudafed and makes it last a shorter amount of time. don’t take sudafed if you have a heart condition, and don’t take it without asking a pharmacist if you are taking other meds to make sure they dont interact negatively.
