The purpose of this study was to know the probable diagnosis and therapeutic action of the flower essences under the light of the Theory of the Imaginary by Gilbert Durand, through the AT.9 test and flower essence interview sessions. It was applied to 30 people, who were being treated with flower essences, by a private practitioner in São Paulo. The study contains 60 AT.9 test protocols and 60 flower essence formulae. It analyzed the common traces, both the attuned and the dissonant ones, by the relationships established between the AT.9 and the flower essence formulae, bringing forward evidences of the capacity diagnosis and the therapeutic actions of these essences. The two essences that translated the characteristic tone of this population were California Wild Rose and Evening Primrose.
