My KNOWLEDGe :-
I know of a man who practices unani.His medicines r herbal, durations r longer than modern medicines but once u finish the the medicines, u r illness will fade permanently(99% probability).He also finds out if anything is wrong in da body by just touching and feeling our hands nerves, This is da most most amazing part of his skills.

IMP question
