"It was excruciating," she recalled. "The only benefit was I did oxygen every night and they had hard surface floors without carpeting. I didn't know really the principals of environmental medicine yet. I just knew that I needed to rest and oxygen seemed to help."
Nagy's husband Wes Nagy said "the psychiatrist that had me commit her told me she would never get well and that I should consider moving on." But after a month of treatment at the clinic, Wes Nagy said that his wife "was like somebody else. It was like somebody had flicked a switch. It was a different person."
If it all sounds a little extreme to you, you're not alone.
"We believe he is posing a threat to the public health of the citizens of Texas," said Mari Robinson, an attorney for the Texas Board of Medicine.
The board is trying to stop Rea from practicing his brand of medicine, and may even strip him of his license. The hearing is set for Dec. 1.
"The treatments that he's giving, we believe, can be dangerous to the public health, such as injecting jet fuel or natural gas," said Robinson, who added that the treatments appear to have no clinical value.
Rea says that he has never injected patients with jet fuel.
"I've used antigens of it, and,of course, as you well know, that was one of the accusations," he said. "I used an antigen, a provocation test, just like we would a food or just like we would a mold."
We asked Dr. David Khan of the University of Texas Southwestern Medical Center, who, unlike Rea, is a board certified allergist and immunologist, if any of this makes sense.
"Certainly injecting jet fuel or any part of jet fuel into someone I think would be potentially dangerous and certainly doesn't seem to have any value," he said.
When asked about the success stories of Rea's patients, Khan said, "They're feeling better living in a closed room with aluminum foil, never leaving without oxygen. Is that a cure? Absolutely not."
Countered Rea: "I might say that in Japan now they have four environmental clinics that are at university medical schools that are patterned after our methods in our clinic." And he maintains that his methods have been peer reviewed in the United States, just not in what most would consider mainstream medical journals such as the New England Journal of Medicine, JAMA or Nature. And his reaction to the actions of the Texas Medical Board is that it "seems like somebody wants to limit the public's chance for freedom of choice in medical care, doesn't it?"
But Robinson, of the Texas Board of Medicine, said that "what's gotten him in trouble is that he has yet, so far, refused to submit his treatments to the double-blind sort of gold standard studies or to an institutional review board to oversee it."
But none of that matters to Lisa Nagy.
"I have a headset on every phone in the home because I can't really use [a regular] phone," she said. "If I hold it up, in the piece here, it's got a magnet and it gives me a headache."
Following Rea's program, she injects herself daily with all sorts of allergy shots.
"This one is terps, which is terpians from wood -- I was very sensitive to pine. Do not have raw pine in your home. Oak is OK. This is chemicals and these are the chemicals that are in this vial, whatever the chemicals are, I was sensitive to some and not to others. So the ones I was sensitive to, they were put in here with water," she said.
