The human sense of smell is an area which has been under estimated, especial-ly in psychotherapy. Recently, an increasing body of ground-breaking evidence has demonstrated the crucial role that odors play in our lives. Most importantly for the topic of the present paper, each individual produces a unique odor signature which is able to communicate - mostly subconsciously - awide range of social in-formation (e.g., emotions, health status, age) to conspecifics. Nowadays, there is an ever-increasing number of people delivering psychotherapies over internet as a practical alternative to traditional methods. However, we need to consider the limi-tations linked to the non-verbal domain on the analytic dialogue. The aim of the present paper is to focus on the role of the sense of smell as a medium for convey-ing important social information within a group.
