I will copy the answer I sent in reply to your identical PM:
The information about anything less than 70 PPM not working is bunk! Particle size and true colloidal content are more important. The best use of silver for asthma is a combination of oral administration AND use of colloidal silver in a nebulizer. Better to use 5 parts silver to 1 part lobelia extract and 1 part mullein extract.
I also highly, highly recommend a Chinese herbal product called ClearLungs which is wonderful for the lungs.
For more information which may help you achieve your goals:
Use Nature Instead of Drugs to Treat and Relieve Asthma

I hope that helps and wish you the best of luck.
