I knew I would find the answer. You need to just find the right term. If you Google "Uruguay homeopatia", you will find many big examples:
Homeopatía Alemana
Homeopatía Farmeco
Homeopática Hahnemann
AMHU - ASOCIACIÓN MEDICA HOMEOPÁTICA DEL Uruguay
I doubted that any country that has a European influence, wouldn't have homeopathy. I still feel that homeopathy can work alongside conventional medicine. But now I know it exists here.
