I practice Qi Gong (yet another spelling) and Gung Fu and can also attest to it's healing powers. I think if you practice Qi Gong long enough, it becomes part of everything you do. There are specific Chinese Qi Gong healing arts, like External Qi healing/ Wai Wi Zhi Liao (precursor to Reiki), but I believe it's also something that can be integrated into any art to take it to another level.
I highly recommend the book "the Way of Qigong - the Art and Science of Chinese Energy Healing" by Ken Cohen. It touches on so much yet there is ample depth to go back it to over and over again.

Excerpt from the section on External Qi Healing:
"EQH is also the most accessible form of Chinese medicine, the easiest for anyone to learn. Although it may be applied as an adjunct to acupuncture therapy, it can also be practiced by those unfamiliar with Eastern philosophy. It does not require knowledge of meridians, acupoints, or Chinese medical theory. Unlike many qigong instructors, I do not believe EQH is only for the advanced. I do not accept that one must wait ten years before attempting it. On the contrary, we are emitting qi all the time, with or against our will. We need to learn how to use this innate capactiy effectively and wisely."
I'm a new MT student, but because of my Gung Fu practice I've noticed I approach many things from a different perspective. If nothing else, Qi Gong practice will get you comments on how warm your hands are
