I can train you about what I do for myself, to deal with my asthma, at home. This technique is based on steam, salt and inhalation.However I am not a doctor nor a technician. I can only advice on my approach I use, and reasons I use it.The kit is easily obtained, and any salt of your choice can be used.In case you are interested, PM me.
