Chinese medicine emphasizes the underlying connection of the bodily, emotional, social, and environmental dimensions in illness experience and healing. The therapeutic process, characterized as tiao (attuning, balancing), targets the patient's overall illness condition and experience including both physical and non-physical aspects of suffering. This study, incorporating techniques of microanalysis as an ethnographic tool and using an actual recorded clinical interaction as data, analyzes how the path to effective healing is negotiated among multiple clinical realities at a clinic of Chinese medicine in Beijing. A close examination of interactive features of actual face-to-face communication between a doctor and a patient in a specific case of "stagnation of emotions" reveals that, for an illness recognized in Chinese medicine as originating from disordered emotions, adjustment of the patient's perceptions of reality and social relations is particularly salient in the "attuning" process. Efficacy then should be understood as more than physiological changes produced by herbs, but also as emergent through an interactive event of clinical encounters. This study demonstrates empirically how the clinical process of Chinese medicine works to define and transform the patient's emotions and experience.
