U.S. District Judge Madeline Hughes Haikala imposed the sentence Tuesday on 61-year-old Isabel Kesari Gervais.
Authorities say Gervais described herself as a naturopathic doctor but wasn't licensed. A statement from prosecutors says she claimed to use naturopathic medicine to cure illnesses including cancer.
Gervais pleaded guilty last year to defrauding patients at a clinic in suburban Birmingham, Alabama.
In her plea agreement she acknowledged operating multiple offices over 15 years in Montgomery, Alabama; Springdale, Arkansas; metro Atlanta; and Leawood, Kansas.
Investigators determined Gervais moved frequently and used aliases including Rose Starr and Debra Lynn Goodman to avoid detection. She had been in Hoover, Alabama, since 2015.
