SAN DIEGO (AP) - San Diego prosecutors say a man who called himself a naturopathic doctor and told patients he could cure cancer has been charged with practicing medicine without a license.

Kurt Donsbach, who treated Coretta Scott King before she died of ovarian cancer in 2006, was charged Thursday with 11 felony counts.

In 1997, Donsbach was sentenced in San Diego federal court to a year in prison for smuggling more than $250,000 worth of unapproved drugs into the United States from Mexico.

The charges filed Thursday include treating patients without a license, grand theft and supplying patients with drugs that are not approved by the Food and Drug Administration.

If convicted, the 73-year-old faces up to six years in state prison.
