This is a video of the first 6 minutes of the talk about Su jok given by Dr Vesna Zdravkovic at the Complimentary Health Expo held at the NZ School of Acupuncture and Traditional Chinese Medicine in Auckland, Nov 2011.

The History of Evolution of the Correspondence Systems Concept Translated from Korean "SU" means "Hand" and "Jok" means "Foot"

Thus this method is one using only hands and feet for medical treatment. Hands and feet carry specific curative systems that follow the principle of likeness; the shapes of the hand and foot resemble the human body. These curative systems are given the name of correspondence systems of hands and feet.
