This book is the result of a master's research whose objective was to discuss the inclusion of flower therapy in the therapeutic practices of the Unified Health System (SUS), as a strategy for the implementation of the principle of integrality in health care to the user. Meeting the proposal of integrality, the Floral Therapy may constitute an important practice of health care, contributing to a greater resolubility and humanization of public services. The results found here indicate that Floral Therapy, by treating the subjects as singular beings and in their totality, allows a differentiated attention. Floral therapy is a therapy consistent with the principles of SUS and can favor the resoluteness of the system. Thus, it would be appropriate and feasible that it was valued for its peculiarities and integrated into the SUS, being recognized and made available as a therapeutic option to the entire population, so that it can contribute to ensuring the completeness of health care.
