Hi Sue, Max Gerson invented his Therapy because he had strong headaches. The Gerson Therapy is also a good way to heal from cancer. 40-50% of terminal cancer patients have been cured with success (and 90% of non terminal). http://en.wikipedia.org/wiki/Max_Gerson http://www.gerson.org/ http://it.wikipedia.org/wiki/Max_Gerson Good luck.
