I have (usually) mild asthma. I visited a dusty wildflower area and contracted fungal pneumonia. The doctor did not apply effective antibiotics, because the infection was fungal, and he initially misdiagnosed it. The infection continued for weeks, and hardened into chronic obstructive pulmonary disease. Over the next year I tried many remedies. Then I found an interesting fact. The ocean has millions of antibacterial virions per liter. This is why there are so few bacteria there: predation. I live in an oceanside city, and have no problem getting clean, fresh seawater. I spat some infected sputum into a bottle of seawater and diluted it to invisibility. The idea was that any virus would rapidly multiply by killing and eating the bacteria of my infection. Then over a week, I sprayed the water and inhaled it. My coughing got worse, but then air began to penetrate past the blockages and I began to cough them up; some looked like french fries. I'm now healthy.
I think a similar effort might work with artificial seawater made from organic sea salt. The idea is that it must be organic so that the antibacterial virions would need to be preserved in the salt.
