Christine Daniel, who is also an evangelical minister, was convicted Tuesday on four counts of mail and wire fraud, and six counts of tax evasion related to income tax filings as well as one count of witness tampering, the Los Angeles Times reported.
The 57-year-old is scheduled to be sentenced Dec. 5 in Los Angeles.
Prosecutors alleged Daniel used her position of trust in the evangelical community and a program on the Trinity Broadcasting Network to sell the treatments, which cost up to $4,270 for a week's worth of product, the newspaper said.
Daniel and her employees claimed the products had a 60 percent to 100 percent success rate in curing terminal cancer. She also claimed to be able to reverse a number of chronic and debilitating conditions.
Prosecutors said Daniels made millions of dollars from patients at her Sonrise clinic in Granada Hills, Calif.
