Linked below is an excellent article from the Faculty of Homeopathy written by the late Dr. Peter Fisher who was unfortunately killed in a cycling accident this summer.
Dr Peter Fisher was Director of Research and Consultant Physician at the Royal London Hospital for Integrated Medicine (RLHIM). A Fellow of the Royal College of Physicians, he is accredited in homeopathy and rheumatology. He is a member of the World Health Organization’s Expert Advisory Panel on Traditional and Complementary Medicine, involved in drafting its Traditional and Complementary Medicine Strategy 2014-2023, and Editor-in-Chief of the international medical journal Homeopathy. He was Physician to Her Majesty Queen Elizabeth II. The RLHIM is part of University College London Hospitals NHS Foundation Trust, one of the largest academic medical centres in the UK, and is Europe’s largest public sector centre for integrated medicine.
This article talks about how homeopathy works as well as the studies, clinical trials and research that's being done in this area of medicine.
This is well worth the few minutes it will take to read.
