What is the difference between a generic medicine and one that carries a well-known maker's name? Surely, it is entirely a matter of perception. Both will be equally capable of addressing the basic need. But if the brand name inspires more confidence in the patient, it may yet cause them to feel better. And who knows what subtle yet crucial difference this small shift of mental attitude may contribute towards the recovery? What you need, is the right solution - not necessarily the most famous or obvious one. Perception/ faith is necessary in every matter.
