In the United States homœopathy has had a long history, with the height of its influence at the end of the 19th century where hardly any city with over 50,000 people was without a homœopathic hospital. In 1890, there were 93 regular schools, 14 of them were fully homœopathic. In 1900, this number had increased to 121 regular schools, with 22 of them being homœopathic. 2.5 million Americans use homœopathic medicines and the magazine of the Rheumatic Diseases Clinics of North America stated that " homœopathy is one of the world's most frequently used complementary therapies".1 The American Journal of Medicine reported in an article entitle 'The Future of Integrative Medicine' that integrative medicine now has a broad presence in medical education, having evolved because of public demand, student and resident interest, increased research, institutional support, and novel education programs: "Now on the horizon is a more pluralistic, pragmatic approach to medicine that is patient-centered, that offers the broadest range of potential therapies, and that advocates not only the holistic treatment of disease but also prevention, health and wellness."2
In Canada, the practice of homœopathic medicine is regulated by provincial jurisdiction, while homœopathic medicines are governed by federal jurisdiction. The Canadian province of Ontario passed a bill in 2007, legislating and enacting homœopathy as a government registered health profession.
Mexico has integrated homœopathy into its national health care system. In as early as 1895, by presidential decree, the first homœopathic school and hospital were established and regulations issued regarding training standards for homœopathic doctors.3
A number of Latin American countries have regulated homœopathy: in Cuba, Argentina and Colombia practitioners have to be doctors who have graduated from a recognised medical school, in Brazil homœopathy is incorporated into the national health system.3
