I suffered from a persistent throat tickle for years to the point of feeling like I was going crazy. I saw a brief comment somewhere about oregano oil. I started taking organic oregano capsules, one at night and within 3 days the tickle was gone! Needless to say, I was thrilled.
I just occasionally get a tiny tickle if I have a cold or am in a dusty environment. I made my own throat spay. A small spray bottle to carry in my purse. whisky with a few drops of oregano oil in it. tastes horrible but coats the throat and instant relief. If it helps anyone else, it is natural and easy. first time I got relief after years of trying everything,
I had bronchitis when my asthma started, but my wheezing and asthma hasn't gone away since then (I took zpack for it)
you should go see a doctor and a pulmonologist
won't vitamin c mess up your immune system?
