Kurt Donsbach, 73, whose dubious health-related activities have
spanned more than 50 years, is facing 11 felony counts including
treating patients without a license, misbranding drugs for sale, grand
theft, unlawfully dispensing drugs as a cure for cancer, and falsely
representing a cure for cancer. The declaration in support of his
arrest warrant states:

    * in literature and his weekly online radio broadcast, Donsbach
identified himself as a chiropractor and a naturopathic doctor. He has
no license to practice any health profession in the United States.
    * In 2001, Donsbach’s Mexican clinic advised one patient to inject
herself with “neuropeptides” to treat arthritis, saying it would “re-
program” her body’s T-cells. FDA tests revealed the “neuropeptide”
contained a steroid not disclosed on the packaging or labels. The
patient paid thousands of dollars for the drugs and injected herself
for six years, leading to severe bone-density loss.
    * Donsbach advertised he had a 60% success rate with pancreatic
cancer and sold an undercover agent a home treatment protocol that
contained nimesulide, a non-steroidal anti-inflammatory not approved
by the FDA. Marketing of the product (Leppin Miradin, a/k/a Fortodol)
has been suspended in Europe because of high rates of liver failure
that resulted in deaths and liver transplants.

The investigation leading to Donsbach's arrest was was conducted by
the FBI, the the FDA, and the San Diego District Attorney's Office.
