For some reason my excessive phlegm that I get shortly after I eat seems to be a lot less than it was only a few weeks ago (and for years before that). What have I changed and what parts of those changes were what has made the difference? First I started taking fisetin just as I finish eating (100 mg of lovusetin), not before eating. Maybe the anti-oxidant effect on top of the food is changing the electrical charge to the vagus nerve that otherwise quickly triggers NFκB and TNFα in the lungs to make phlegm. Second, I started taking a yogurt drink about every two weeks and that may be changing the microbiome in the gut that is affecting that signal to the lungs that otherwise says it was invaded and phlegm is necessary to attack the invader. Third, I started taking tadalafil (Cialis often used for ED problems in old men) which was originally designed for pulmonary arterial hypertension to open blood vessels in the lungs. Tadalafil has been tried in what seems to me to be stupid designed trials that showed it did not help COPD, but for me I think it is what has cleaned out the micro-vessels and I am breathing a lot better(get the phlegm off the lung epithelia and clean out the blockage in the endothelia, and you get better gas transfer). I still may cough a little, but it is no longer from deep down in the lungs and requiring lots and lots of coughing to get it up. It seems to be moving up more naturally. What very recently caused this positive change? Did the fisetin get rid of senescent cells (like Mayo Clinic trials seem to be trying to do) and let my natural lung stem cells rebuild part of my alveoli? Is there a possibility the cilia are rebuilding? Is this change for real and will it last???? Your comments would be appreciated.
