Abstract
The growth processes demonstrated by living organisms are one of the most complex of all biological functions, having defied analysis and understanding for centuries. Physicians have long wished to be able to control growth, to speed it or to increase its competancy in healing processes and to stop it in the case of malignant tumors. Biochemical concepts, based upon metabolic inhibition have enjoyed but a limited success in the control of some malignant tumors, and have been unsuccessful in enhancing normal healing processes. Over the past two decades an increasing data base has been constructed indicating that both direct electrical currents normally generated within living organisms and time varying components of the Earth's normal magnetic field play pivotal roles in the control of biological growth processes. It is the aim of this paper to review this data and to suggest a unified concept relating normally occurring electromagnetic forces to the control of normal growth processes.
