I highly recommend that you purchase the Balancing the Heart Qigong DVD available at Masich Internal Arts
I also highly recommend “Qigong Empowerment”, the best book on qigong that I have ever found:
Qigong Empowerment: A Guide to Medical, Taoist, Buddhist and Wushu Energy Cultivation

I would love to see trustworthy, scientific, reproducible, double blind studies done without political influence. Unfortunately, such studies are few and far between.

Its purpose is to normalize vasovagal function, improve blood pressure, balance the heart, and reduce unhealthy clotting of the blood.
