XXXIX GIRI Meeting
April 15 – 17, 2026 – Warsaw, Poland
Venue:
ADN Conference Center
Browary Warszawskie
Building GH; entrance B
Grzybowska 56 Street
For the first time, the annual meeting of the GIRI will be hosted by the Polish Homeopathy Association (PTH) and held in partnership with the European Committee for Homeopathy (ECH). With a scope on the clinical application of homeopathic medicines, the three groups join forces to integrate the experimental models and basic research conducted by the GIRI members, and to focus on the effectiveness of homeopathic drugs in daily clinical practice. As a prominent feature of the previous meetings, the cutting-edge scientific results on high dilutions and homeopathy will be presented in 2026, covering topics in basic research in physical-chemical and biological studies and their bridges to clinical practice.
In short, it will be a point of convergence between two crucial areas and an opportunity to deepen discussions on the results of clinical research.
Scientific papers involving recently published, completed, or not-yet-published partial data can be presented and open to peer discussion before completion. Protocols and projects in the initial phase are also welcome for discussion. The GIRI´s original nature is to be a laboratory of ideas so everyone can think and build knowledge together. The result of this movement is to envision solutions and mitigation strategies for serious contemporary problems related to human, animal, and environmental health by improving bio-resilience.
At this event, the presentations will be distributed at similar times among GIRI, ECH, and PTH, as well as invited authors whose abstracts had been approved by the International Journal of High Dilution Research – IJHDR – review committee.
Non-member participants are also welcome to attend as an audience and participate in the discussions.
