I believe that level two there are techniques which are aimed at breathing problems and asthma. Don't hold me to that becuase I haven't had the chance to fully review the manual.
I have to add that this is also of interest to me becuase my mother suffers from hay-fever quite bad that she borders on asthmatic. I would like to know if the usual Qigong techniques for breathing/lungs techniques in level 2 can work to rid her of her hay-fever (its already done wonders for her shoulders pains and neck ache).
