GNI Symposium 2026
This year, the Symposium is in person. It will return to Goodenough College, Mecklenburgh Square, London WC1N 2AB, on Saturday, 17th October 2026.
Booking details will be uploaded soon. Hint: It will be a blend of traditional and Modern Iridology, with brand-new ways to look at and define signs and marking in context.
The body is always speaking — through the eyes, the face, the tongue, and even the nails. In this workshop, we’ll explore how these visible signs reveal deeper insights into vitality, balance, and constitutional patterns. By learning to observe and interpret these natural indicators, practitioners can expand the language of assessment beyond the iris and begin to see the body as an interconnected map of expression.
Designed especially for Iridologists and Natural Health practitioners, this workshop introduces practical ways to integrate tongue, face, and nail analysis alongside Iridology. As these observations come together, a fuller picture of the client emerges, allowing practitioners to refine their understanding, deepen their assessments, and develop more responsive and personalised natural therapy protocols.
