Polarity therapy is a lesser known branch of complementary medicine and was developed by Dr Randolph Stone. He was a qualified naturopath, osteopath, chiropractor and neuropath who practiced in Chicago. He also discovered a book called Mysticism, the Spiritual Path Vol II by Lek Raj Puri in 1945 which explained to him the concept of energy, its origins and its proper use for healing. Polarity therapy was the result of his course of spiritual study with the author.  

Polarity therapy is the science balancing the opposite energies inside the body to promote mental, physical and emotional health. Its name suggests that the image of the body represents a living magnet where electromagnetic energy flows between its positive and negative poles. Dr.Stone concluded that the ultimate cause of disease was blocked energy due to external factors such as poor diet and lack of energy or internal emotional stresses. Once the energy is unblocked, it flows freely restoring the mind and body to health.
