Bio-Dynamo-Chromatic (B-D-C) Diagnosis

Bio-Dynamo-Chromatic (B-D-C) Diagnosis was a method developed by George Starr White to diagnose illness in a patient through percussion of the abdomen in conjunction with directional positioning in space and the use of coloured light rays. Among other claims, White held that the B-D-C diagnosis would uncover cancers "before any known method" and positively detected a variety of ailments, including gonorrhea and syphilis.
