All COPD nebulizers are just very weak salts that they charge big bucks for. The first thing they do in hospital is put people on IVs which is just ionized table salt, sodium chloride. I made steamers with honey, pink Himalayan sea salts, and braggs apple cider vinegar. For the kidney's take one teaspoon of Shaklee Liquid Resveratrol and watch the creatinine levels go back to normal in 3 days. I tried to give Melania that remedy before her operation but could get above all the tens of thousands of twitter posts. Normal creatinine levels are .24 to .26. At .50 you have 50% kidney failure, and they consider at .38 terminal. The VA would not give my relative this stuff and waited till he was at .58 before they allowed me to resume treatment. In two days, I got it down to .33 and they panic, and did other nefarious things to him that he finally succumbed to. No Justice in this country.
