I think you are talking apples and oranges. I used to teach Qigong (and martials arts).
Qigong is wonderful for physical, emotional and spiritual health and harmony. The 7 steps or any program of visualization is for life-enhancement, and change.
Having said that, Qigong will clear the airways, so to speak. By the way, one does not have to perform any specific Qigong regimem (regardless of marketing efforts). Unless it is one tailored for specific body systems, like the '8 Brocades' any are beneficial.
Even doing nothing more than basic Qigong breathing perhaps combined with 'hugging the tree.'
Make sure you glue your tongue to your upper palette when doing Qigong.
Hope this is helpful. Feel free to contact me if you have any questions.
