Mullein Tincture - very powerful
I first tried this a few years ago when I had the most dreadful chesty phlemy cough. After 1/2 hour of taking the ready made shopped bought tincture it all came up! Funnily not by coughing. I blew my nose and I am not joking when I say, for about 20 mins non stop! The relief of being able to breathe better and not having a chesty cough was incredible! I carried on having the chesty cough later that day but then just took more of the tincture.
Since discovering ACV on this site, I think that would be good to take as well and seems to speed up the healing process too!
Common mullein flowers, brewed as a tea, make a powerful cure for cough or upper respiratory disease, among other things. There are no side effects, and it tastes wonderful.
