While an interferon therapy is a conventional method for treating hepatitis
C, no particular option exists currently in the treatment except for this
interferon therapy. An object of the present invention is to provide a
novel method for treating hepatitis C. The present invention includes a
method for treating hepatitis C comprising warming a liver region of a
human by sandwiching an upper abdominal region of a human body between
electrodes on the front and back by supplying a high-frequency electric
power to these electrodes.
