A 73-year-old California man is under arrest for practicing medicine without a license and supplying patients with supplements containing non-FDA approved drugs.

Kurt Walter Donsbach, who claimed to have the cure to cancer, faces 11 felony charges ranging from treating patients without a license, misbranding drugs or sale, grand theft and unlawfully dispensing drugs as a cure for cancer.

Donsbach is scheduled to be arranged on Monday in a California courtroom.
