Robert Medhurst in his article "In Defence of Homeopathy" cites scores of helpful studies and statistics. These can be read in the March edition of the ezine Homeopathy for Everyone at http://hpathy.com/homeopathy-papers/in-defense-of-homeopathy/
For me, however, the bottom line is that people have been being cured gently by homeopathic treatment for over 200 years. Like herbal treatment, it has never gone away - because it works. And if something works, you should use it. Sometimes the disease treated is too advanced for homeopathics to restore the body to health, but often even in such cases it can palliate the symptoms. One thing one can say: no homeopathic remedy has ever had to be withdrawn because of its side effects.
