I'm not pushing Colloidal Silver here. I promise. The question came up as to whether the use of CS would interfere with putting drops of probiotic in the nose. My answer is yes. Definitely. It has actually helped me in this situation; but only short term. CS has also helped very much when I feel flu like symptoms arising. It is a cure for me. I always keep it handy. Make it myself; but prefer Nutrasilver.
I'm not sure about putting kefir up my nose. Especially if I make it myself. I'm not trustworthy with fermentation. Not even sauerkraut. That's why I was wondering about that solution that claims the "results" of probiotics as more important than the probiotics themselves. And if it would be as beneficial up the nose.
