I have severe doubts about something like this being able to heal asthma. It very likely helps against asthma attacks and when it's triggered, but asthma in general is an allergic reaction. Slow breathing can help control it by limiting the irritation in the upper airways so that they don't constrict as quickly, but I don't see how it would get rid of it entirely.
