Many technically “use” both and what is generally termed “medical qi gong” is essentially the Chinese Medicine/Martial Arts version of energy healing - loosely akin to reiki but more strongly interwoven with the same theories as Chinese Medicine.
So, yes, people technically use energy healing methods with Chinese Medicine, but a useful discussion of this (in my opinion) would require both a deep understanding of Chinese Medicine theory, at least a decade of clinical experience with it, a strong personal practice of internal arts and at least as many years or so of the clinical application of energy work. The way these system overlap and are used is not something that can be easily put into words - words of much value anyhow. But the thorough guidance of an accomplished master can discuss it over time in person with an eager and well read student. This is why learning Chinese Medicine well is best served by spending years and years with an accomplished master - after - all of the formal schooling, your own indepth explorations, some clinical experience and a strong personal practice. It’s really a lifetime commitment, particularly at the level where these systems merge.
