Krongrad A, Droller MJ: Zinc and the prostate. Paulson DF (Ed), Prostatic Disorders. Lea & Febiger, Philadelphia, 1989
A most comprehensive review of a most esoteric subject: prostate zinc. No evidence is provided to support natural treatments for prostate cancer, as is often requested.
One often also hears about selenium as one of the natural treatments for prostate cancer, usually in the context of prostate cancer prevention. You can read more on this point in Dr. Krongrad's published piece called The Ghost of Larry Clark in the Editorials section: http://www.laprp.com/editorials.php .
