Every human has self healing energy, sometimes it just doesn't function properly because of external environment or types of food eaten.
take for example some medication would work for someone and wouldn't work for someone else, the common denominator is the self healing energy, it either works properly or not, as the anatomy and the medication are the same.
What I do is help activate the self healing energy of the person, by sending them energy. It is a gift I have and i am helping people with.
Do a search on the internet on distant healing and you will get a lot of information.
