yes glutathione powder dissolve in distilled water would be a nice nebulizing solution for emphysema. I have try that with my patient with very good results. But be sure to use a pure glutathione powder with no addictive, or you might have a bad reaction. I use the glutathione powder by Hulda Clark is 100% pure.
Also try doing a detox thru nebulization using NCD zeolite, start with 5 drops with 3cc distilled water, 3x a day. You see a remarkable improvement.
