I am here for the first time, have knowledge about acupuncture but not about Qigong.

I am 43 years and have to cope with seasonal asthma. Acupuncture helped me a lot this winter and now I would like to learn a `technique` or something similar to strenghten the respiratory system for the next cold season.

In brief:
Is Qigong helpful in cases of asthma ?

Many thanks for any advice,

Mary
