Homeopathy is not a medical science, so you cannot have a MD in
Homeopathy. As far as I can tell, he never attended any university and I think he just gave himself the MD title. As for his book, it is about Homeopathy, so as far as I am concerned, it may as well be fiction.
If you believe in Homeopathy, that is your business. But if you try to recommend Homeopathy here to cure HBV, you will face opposition.
