On Christian TV, author Valerie Saxion of Keller made her fame selling pills and herbal supplements as "Dr. Val," the "Parasite Lady."
But state attorneys are worried that she might be preying on viewers.
Attorney General Greg Abbott's lawyers are suing Saxion in Tarrant County district court, asking a judge to stop "Dr. Val" from claiming that her supplements are any kind of cure-all or from calling herself a doctor.
According to the lawsuit, state health investigators found that Saxion, author of the 2003 bestseller How to Feel Great All the Time, claimed that her supplements inhibit cancer growth, lower blood pressure and cure insomnia, among a list of more than 40 medical claims that the state describes as unproven.

Saxion calls herself "Dr. Valerie Saxion N.D." But her "doctorate in naturopathy" is from a notorious, unaccredited distance-learning school in Alabama.
Under Texas law, it's a crime to list an unaccredited or "substandard" degree. The lawsuit accuses "Dr. Val" of deceptive trade practice.
A Star-Telegram reporter could not reach Saxion, 49, or her lawyer, Greg Jones of Southlake, on Tuesday.
But in 2004, a reporter profiled the "Parasite Lady."
Back then, Saxion -- calling herself a doctor -- claimed that 85 percent of Americans suffer from parasites and need a "cleanse."
She said her children were so conscious that they would say, 'Mom, come look. Is this a parasite?'"
As of Tuesday, her website still sold herbal products including a supplement, ParaCease, labeled as "Treatments for Parasites." The price: $42.95.
Abbott's office has aggressively defended freedom-of-religion cases and the right to prayer, but also must defend state health laws.
A state spokesman said Saxion made "outrageous claims."
Her books mix dietary and nutrition advice with large doses of Christian faith. According to her website, her current TV show Alternative Health runs weekdays on several Christian networks, including televangelist Paul Crouch's Trinity Broadcasting Network.
Another one of her books promises "Vibrant Health ... God's Way."
She'll have to run her business Texas' way.
