Homeopathy was discovered over 200 years ago by the German physician, Dr. Samuel Hahnemann (1755-1843). By the early 1840s, homeopathy was growing in popularity. It had established itself in many countries. At the turn of the 20th Century, homeopathy was being practiced in over 60 countries worldwide, including France, Germany, Great Britain, the United States, Italy, Sweden, Denmark, Austria, Norway, Holland, South Africa, Argentina, Mexico, India, Sri Lanka, Russia, and many other countries. It is estimated that over 400 million people were receiving homeopathic treatment at that time. Homeopathic hospitals and medical schools were being established all over the world.
