NO. i suppose you will say that of allopathy too if you come across an idiot practising allopathy or if you come across fake drugs which are so rampant.
samrat ashok never destroyed any ayurvedic texts you idiot. its was khilji, get a history lesson before you spread lies.
modern day ayurveda is sound in its principles. in fact much of the herbs form the basis for many allopathic medicines - the active ingredients are all common.
