Tui Na is a professional branch of Chinese medicine.  It uses hand manipulations (massage) for therapeutic reasons.  Tui Na utilizes the same theories and principles of health and disease as acupuncture and herbology, which are other two major elements of Traditional Chinese Medicine.  While sharing the same basic energetic theory, each area uses different means for influencing the energy of a person toward health and away from disease.  All three therapies attempt to achieve the same results.
