We use five parts colloidal silver to one part lobelia extract (5 ml to 1 ml) and breath through the nebulizer until it is gone. Mullein might also make a good addition (1 part, or 1 ml). I urge you to try a Chinese herbal formula supplement called ClearLungs Extra Strength. We have had wonderful results with the combination of nebulizing as described above two or three times a day and taking the ClearLungs supplement. We also take colloidal silver orally if we feel a bug coming on or if one is going around.
You might want to start off with half the amounts above and work your way up to the full amounts if you feel too much fluid accumulating in the lungs. I predict that you will be pleased with your results (and let us know how it turns out if you do give the suggestions a try).
You can see all the herbs in the ClearLungs supplement and what they do here:
Should you decide to buy from CureZone sponsor Utopia Silver be sure to use the group discount code of LR001 if the supplement is not on sale at the time to get 15% off. You might find an even better price at iherb.com, but last week when I checked they were out of stock.
I also suggest you take a look at this article:
Congratulations. I don't think that the strength is critical. I use the 20 PPM Advanced Colloidal Silver. A good home brew should work fine for nebulizing. More than 20 PPM is overkill and anything less and I use 5 ml in combo with 1 ml of lobelia extract per breathing treatment. You can just use a bit more often. As far as how long to continue goes, I would say to continue doing the nebulizing once daily for a week and then perhaps cut back to every once in awhile. And don't neglect the oral silver solution use either, when needed. I personally do not take silver orally except when I think there is a need.
I look forward to your post about the mouth cancer in cats. I may well want to share it with our pets group. Colloidal silver, properly made oleander extract (or oleander supplement) and inositol/IP6 have been an effective combo for many cats, dogs and other fur-friends.
BTW, you weren't dumb. There are lots of things you can take orally that might not be wise to breath. Silver just isn't one of them.
All the best,
