Sympathetic Resonance Technology: scientific foundation and summary of biologic and clinical studies

J Altern Complement Med. 2002 Dec;8(6):823-56. doi: 10.1089/10755530260511838.


Sympathetic Resonance Technology (SRT; Clarus Products, International, L.L.C., San Rafael, CA) is a novel technology used in consumer health care products to protect humans from the potentially harmful effects of stress. A summary of the previously unpublished studies on SRT, both basic and clinical, is presented. These studies collectively show that SRT mitigates the stress response for a variety of stressors such as chemical and electromagnetic stress in various biologic systems and multiple levels of organization, ranging from the molecular to the behavioral. A rudimentary model of how SRT may work at the level of the biofield, the endogenous electromagnetic field of the organism, is proposed. By interacting with key component frequencies in the biofield, SRT may stabilize the organism homeodynamically, thereby protecting it from the effects of stressful stimuli.
