Keep treating your Dad on the Incurables Program. Dr. Schulze is a genius and if anyone can help him, Dr. Schulze can.
I looked up what Dr. Schulze recommends when treating pneumonia. He says to use Enchinacea Plus, (to boost the immune system) SuperTonic, Sinus/Lung, Garlic, Clinical Air and Lobelia. I would order all of it and try it.
Also, I believe in the power of prayer, so I will say a prayer for your Father.
