What is the best alternative treatment for pnuemonia?

Use mainstream Rx: Untreated pneumonia is often lethal. Use any "alternative" or "complementary" Rx only as an adjunct. There are few pneumonia quacks because the outcome is generally good and it's obvious when the treatment is working. By contrast, "alternative" practitioners thrive on the desperation of cancer victims with more grim outlooks. Be discerning especially about claims that sound too good to be true.
