Deborah - I make my own ... usually 22-29 ppm. I don't smoke. and usually if sick take the CS at a couple of ounces every few hours. and nebulize it. so far .. the pneumonia progresses and i end up on antibiotics. As maintenance I just take at least once a day .. an ounce or two. Maybe combining it with the electrolytes will make it work better for pneumonia. Will try it.
