The Hellenic Survey of Geology and Mineral Exploration (EAGME) has successfully completed the Technical Study for the Characterization of Clays and Volcanic Rocks for Therapeutic Use.
The project focused on describing and delineating the country’s therapeutic clay deposits, developing a comprehensive database, and analyzing the physical and chemical properties of both recognized therapeutic clays and new, unexplored deposits to assess their suitability for therapeutic applications. In total, 99 locations across Greece were analyzed, with 514 observation points recorded.
The identification and promotion of therapeutic clay sites contribute to the development of wellness and spa tourism, while also highlighting the importance of Greece’s natural healing resources for local communities and the national economy.
Greece holds significant potential to become a leading destination for thermal and wellness tourism, thanks to its unique bioclimate, the combination of sea and thermal springs, its rich cultural heritage, favorable climate, stunning natural landscapes, and highly skilled medical and therapeutic professionals.
It is noted that by 2025, medical and wellness tourism is expected to be among the world’s largest industries, with global revenues estimated between $45.5 and $72 billion and annual growth rates of 15%–25%. Approximately 14 million cross-border patients worldwide spend an average of $3,800–$6,000 per visit, including medical services, travel, and accommodation expenses.
In Greece, the Clay Therapy Center of Krinides, Agia Triada of Messolonghi, and the Loutra Kyllinis Spa and Clay Therapy Center are officially recognized sites for clay therapy. The clay of Sagiada in the Municipality of Filiates is also expected to be submitted for official recognition by the Ministry of Tourism and the Committee for the Protection of Thermal Natural Resources. EAGME has already delivered the relevant hydrogeological study, which confirms the clay’s strong development potential and its suitability in terms of quality, microbiology, and quantity.
The “Final Technical Study for the Characterization of Clays and Volcanic Rocks for Therapeutic Use” was carried out by EAGME’s scientific and technical team under the supervision of Dr. Konstantinos Athanasoulis of the Department of Geothermal Energy and Thermal Natural Resources (GEOTHE). The project was implemented within the framework of the OPYGEK Program – “Studies and Research Supporting the Energy Sector, Industry, and Entrepreneurship”, co-funded by the European Regional Development Fund (ERDF) and the Hellenic State through the Operational Program “Competitiveness, Entrepreneurship, Innovation” (EPAnEK) of the ESPA 2014–2020 (2023).
