Early successes with homeopathic methods in Europe led to its spread to America and throughout the world. Many prominent European doctors emigrated to the U.S., where homeopathy flourished during the 19th century.
By 1900, homeopathy was more prominent in America than it was anywhere else in the world. 20% of American doctors called themselves, specifically, homeopaths, and there were 22 homeopathic medical colleges, more than 100 homeopathic hospitals, and 1000 homeopathic pharmacies.
Many of the American cultural elite of the 19th century were homeopathy’s strongest advocates, among them Mark Twain, William James, Susan B. Anthony, Louisa May Alcott, Henry Wadsworth Longfellow, Henry David Thoreau, and Harriet Beecher Stowe.
Homeopathy has an outstanding track record in preventing and treating epidemic diseases. Dr. Nancy Malik created comparison charts on survival rates between those treated with homeopathy and conventional medicine during the great world epidemics. These charts include diseases such as cholera, pneumonia Spanish flu, yellow fever, and typhus fever. Recent epidemic diseases treated by homeopathy are also noted. These include: influenzas (including swine flu), hepatitis A, dengue fever, leptospirosis, and conjunctivitis.
