Think about yourself. You don't believe anything which contradicts those 700 years of work. You don't believe that water can have a memory. You don't believe there is some sort of energy/frequency stored in water or sugar which cures us. Why? Because we cannot see it or prove it with any known scientific methods. Right?
Well I was exactly like you. I got helped by homeopathy by chance and probably a "hacker" (as defined by Paul Buchheit) within me got curious if homeopathy is really works and is as miraculous as it claims?
I spent time, took medicines myself and my volunteer friends and family. It is still hard to believe for me but it works and it looks more than placebo effect.
I did not read it in a book. I actually experienced it. And my experience of 10 years tells it works.
