What is it with fortune cookies?

I recently opened a fortune cookie that offered me the following advice:

Nature, time and patience are the three best physicians.

This piece of wisdom led me to reflect on healers and different types of healing.  Many people limit their idea of healing to the physical realm or, only to things they can see or feel.  Think of physiological diseases, broken bones, ripped cartilege, and things like high blood pressure.  You may assume that if a person doesn't offer you a means to eliminate such physical problems, then that person couldn't possibly be a healer.
