I always use this simple way to clear my stuffy nose or ease an itchy throat. A bowl of hot water, a towel and some sea salt or essential oils. For clogged sinuses it's actually even better to inhale the steam with your head upside down. I know sounds funny but it actually helps to drain the sinuses more effectively. It's one of those great tips I have been given. I just find something to hold on to and put the bowl very low... bit awkward at first but works wonders.
