A word from Frank Navratil BSc. N.D.


“I really believe that the world is changing. People are changing. People are searching for a greater fullfillment. We will look at the past as a primitive time. War, money, drugs, greed, power, racism. These are primitive words. Words of the second millennium.

Cooperation, exchange of ideas, common goals, respect for nature, equality and natural means of diagnosing and dealing with disease are words of the third millenium, the new millennium.

I have worked endlessly to write, design and create these iridology and nutrition related products, courses and educational resources so that I can share my experiences with you all. I sincerely hope they will enhance your understanding of natural means of dealing with disease. I wish you as much success and satisfaction as the rewarding career of natural medicine has offered me. ”
