When you have mucus/phlegm in the throat due to post nasal drip, get some Silver Biotics (it is the only colloidal silver that really works for me) and make a nasal pray with this solution.
Don't add anything, just spray your nose 3 times daily, 2 spray in each nostril. It will fix the post nasal drip and allow the mucus to get out your nose.
THEN move on to the mucus and phlegm in the throat, here is an INSTANT remedy that will work 100%, all the time and it took me a minute to find this one.
1 - Get some Apple Cider Vinegar and mix it with 1/3 Apple Cider Vinegar, 2/3 cold water
2 - Do a gargle then bend over and stay in this position for as long as you can (minimum 3 minutes). Try to bend over and hold your feet.
3 - While bending, press your tongue against the roof of your mouth every 2 to 3 seconds.
What will happen is that:
a) The mucus/phlegm will attached itself to the mixture as Apple Cider Vinegar acts like a sponge.
b) The gravity will let the mucus/phlegm in your throat to fall in your mouth.
You will feel it falling inside your mouth and when you do, please do not stop because there are usually a lot more coming up.
So continue and each treatment should be at least 3 good gargles. You can do that as often as you like until the mucus/phlegm is completely removed. You can end your session by sucking on honey or drops to soothe your throat.
And VOILA!
Wow! Came across this tip and although unpleasant, it most definitely works. I had gotten so used to the constant congestion, post nasal drip and coughing up of phlegm that I forgot how wonderful it feels to not have that present. I've been drinking ACV off and on for years, but never used it in this fashion. I will make this a regular part of my routine now that I see it works so well. Thanks again for this great info!
