The FDA deleted the warning. The autism "cures" didn't go away.

In December 2025 the federal government quietly deleted one consumer warning page on FDA.gov, the page that told parents which autism treatments to avoid. Not a policy. Not a law. One page. Chelation, bleach, hyperbaric oxygen: gone, with no replacement and no update.

In this episode of The Ashleigh Report I walk through what that page said, why every product on it is still for sale, and how the evidence stacks up for the treatments parents are pitched next. I rank them from strongest evidence to weakest, and I give you four questions to ask about any treatment.

Not sure what to do with everything you have been pitched? You do not have to sort it out alone. On a 45-minute family care mapping call, we look at the providers and supports you already have and what one shared plan could look like. Book a 45-minute family care mapping call

I am a BCBA, but I am not your BCBA. This is general education, not treatment, and not a treatment recommendation for your child or your state. Build the real plan with the people who actually treat your child.

Why parents go looking

Before I name a single product, I want to say the thing that has to be true underneath all of this. Nobody arrives at chelation or a parasite cleanse because they were careless, gullible, or not paying attention. They arrive because they were handed a diagnosis, told "good luck," and left to build a treatment plan alone at two in the morning from a search bar, with a complete lack of trust in the healthcare system.

If you have ever Googled something at midnight because nobody on your child's team would call you back, this section is for you. Not about you, but for you. Every single thing in this episode is a rational response to an irrational amount of abandonment. That does not make all of it safe. But it makes all of it make sense.

This episode is also not about fixing your child. It moves through very different kinds of claims, and I treat each one differently: obvious danger, danger that looks like real medicine, open science that is still being figured out, a real diagnostic controversy with a market built on top of it, and a drug the government hyped in public and then had to walk back.

The old playbook: what the FDA page named

In 2017 the FDA posted a consumer warning page, and it updated the page in 2019. On it, the agency named six specific things parents were buying to "cure" autism. Most retellings only mention two. All six start from the same theory: autism is caused by something toxic in the body, so get the toxin out and you fix the autism. That theory has no scientific basis, and look how far it traveled anyway.

Chelation is a legitimate medical procedure for heavy metal poisoning. It has nothing to do with autism. Dr. Helen Tager-Flusberg of Boston University has said on the record that chelation and hyperbaric therapy "have already caused deaths to several autistic children." The CDC also documented the death of an autistic child in 2005 from dangerously low blood calcium during EDTA chelation.

Chlorine dioxide, sold as "Miracle Mineral Solution" or MMS, is industrial bleach. It has been marketed in some parent communities as a treatment for parasites and for autism. The FDA's own warning is blunt: it can cause severe vomiting, diarrhea, life-threatening low blood pressure, and liver failure. News investigations have documented parents giving it to their children. I did not find reporting that confirmed arrests, custody outcomes, or sentencing, so I do not claim any.

The other four are hyperbaric oxygen, raw camel milk, detox clay baths, and essential oils. On the last three, the FDA's language is almost gentler, which is what makes it more damning. Those products "have been marketed as a treatment for autism or autism-related symptoms, but have not been proven safe and effective for these advertised uses." There is no injury story attached the way there is with chelation and bleach. The complaint is simpler: nobody has ever shown they do anything, and parents pay real money while the window for early intervention keeps closing.

The page came down. The products did not.

One theory, six products, and one pattern: a theory, a product, a testimonial, and then, for at least three of the six, documented physical harm. That page put all of it in one place for parents. The page came down, but every one of those six is still for sale.

Parasite cleanses and how to read a label

The old products did not disappear. They ended up in a new bottle with a fresh label. I split this into two topics on purpose, because blending them would be as dishonest as the marketing I am criticizing. This section is the do-it-yourself, buy-it-online version. The researcher-led version comes next.

Commercial products combine ivermectin and fenbendazole and are sold openly on major online marketplaces. Fenbendazole is a veterinary dewormer. It is not approved for human use. Dr. Peter Hotez, who has built his career on parasitic disease, says plainly that no single product treats "all" parasites the way these cleanses claim. An infectious disease physician I quote makes the sharpest point: if a parent is repeating a "cleanse" every few weeks to months, ask yourself what that tells you. It tells you it is not working.

The documented harms include undisclosed ingredients linked to organ damage, and induced diarrhea that risks dehydration, malabsorption, and electrolyte imbalance. I did not find a documented pediatric death from dewormer misuse, so I am not going to hand you one. That is still bad enough.

Here is a label skill that works on anything in your medicine cabinet. Watch for:

1. A "proprietary blend" with no individual dosages listed.
2. No third-party testing seal, so nobody outside the company has verified what is in the bottle.
3. Any claim to "treat," "cure," or "prevent" a named medical condition, which a legal dietary supplement is not allowed to say.
4. A dosing schedule that repeats indefinitely and never resolves into "and then you're done."

That is not a supplement. That is a marketing document wearing a supplement's clothes.

Fecal transplants, antibiotics, and the gut-brain axis

This is where it gets harder, because some of this is real science. There is ongoing research into helminthic therapy, which is controlled, dosed exposure to specific organisms, built on the "old friends" hypothesis. There are blinded fecal microbiota transplant trials underway at a major university with more than 80 participants enrolled. A researcher I cite argues for standardization and clinical oversight precisely because people are already taking this into their own hands. The people running careful trials are the same people begging parents not to try it at home without them.

The do-it-yourself version carries documented risk. Home fecal transplants can transmit infections, and the FDA has issued safety alerts after antibiotic-resistant infections showed up in transplant recipients, including one death. That event was a general safety event, not specific to autism. My straight answer: this is a real, open scientific question. It is not a settled cure, and it is not a scam. Both are true about the same field.

A related story: sometimes a child on the spectrum is put on an ordinary antibiotic for strep or an ear infection, and for a little while they talk more and make more eye contact. A father published a one-child case report about exactly that. One child is what "n of 1" means. There is also an older study from 2000 using oral vancomycin in 11 children. A psychologist blinded to who had been treated scored videotapes and found improvement in 8 of the 10 children studied. But the gains were largely gone by follow-up, and the authors wrote that "the protocol used is not suggested as useful therapy."

The working theory is that certain antibiotics temporarily suppress gut bacteria that may affect the brain. That is a hypothesis under study, not an established mechanism. The effect is temporary, repeated antibiotic use carries real risk, and some autistic children react the opposite way, with more irritability and regression. If your child shows you, even briefly, that they can communicate more than you realized, the answer is a communication tool and a team that can build on it, not a pill that stops working when the prescription runs out.

Hyperbaric oxygen

The claim is that pressurized oxygen in a sealed chamber helps autism symptoms. The evidence is genuinely mixed. One study in 2009 reported positive behavior changes, a better-designed study the same year found no benefit, and the Association for Science in Autism Treatment says "there are no studies with strong experimental designs evaluating whether or not hyperbaric oxygen therapy is effective." There is also a physical risk that has nothing to do with autism: fire and explosion risk as equipment, middle and inner ear injury, and a significant drop in blood sugar.

Halfway through, and if your head is spinning, that makes sense. Every family I talk to is holding a pile of options and no one to help sort them. We can sort them together on a care mapping call. Book a 45-minute call

Supplements: B6, magnesium, and probiotics

Nobody rushes to the ER over a vitamin regimen. The cost here is your time, your money, and the coordinated plan that never gets built while you manage a supplement schedule. I walk through these in order, from weak evidence down to none.

Vitamin B6 with magnesium. A Cochrane systematic review concluded that "no recommendation can be advanced regarding the use of B6-Mg as a treatment for autism," because of few studies, weak methods, and small samples. Cochrane did not say B6 is dangerous. It said there is not enough evidence to recommend it.

Probiotics. A 2021 review found "limited, but preliminary evidence of efficacy," mostly from small, early-stage, open-label studies. "Promising" and "preliminary" are not the same word.

Gluten-free, casein-free, and other restrictive diets

There are two very different things under this heading. Gluten-free, casein-free diets have a small stack of real studies behind them. A 2022 meta-analysis pooled 7 studies with 338 participants and reported benefits, but the authors themselves flagged small samples, parent-reported outcomes, and inconsistent protocols, and called for more high-quality trials. Weak studies, but real ones.

The GAPS diet and the Specific Carbohydrate Diet are different. I could not find a rigorous controlled trial testing either one for autism. What exists is case reports and parent testimonials. Four things sold with the same confidence in a Facebook group, and four completely different evidence bases once you go look.

Stem cell tourism

Some families fly to clinics in Mexico and elsewhere for stem cell injections marketed to reverse or significantly improve autism. This is an unapproved intervention with no FDA-cleared evidence for autism anywhere. A CDC report published May 9, 2024 tracked three American patients who developed the same drug-resistant infection after stem cell injections at clinics in Mexico. The infections were genetically almost identical even though the patients used different clinics more than 100 miles apart, which suggests the contamination was in the product itself.

Two well-known tumor cases circulate attached to autism online. They are real, but neither involved autism. They are relevant because it is the same industry marketing the same way. Published stem cell case series specifically for autism report no serious adverse events in the literature I could find, but that does not make it safe. The danger is the documented infections and an unregulated industry.

The pattern to watch: no insurance coverage, hidden costs stacked on top of the advertised cost, no refund or legal recourse if it fails, and marketing built on emotional appeal, testimonials in place of research, one treatment for a dozen unrelated conditions, and pressure to pay upfront. The warning came down. The clinics are still taking deposits.

PANDAS, PANS, and the Cunningham panel

This one is different, and I say so up front: PANDAS is not a hoax. It is a real, actively debated diagnosis with real NIH history, proposed in 1998 for sudden-onset OCD and tics triggered by a strep infection. PANS came later as a broader umbrella that drops the strep requirement.

The controversy is real too. NIH's own largest study found no association between the timing of strep infection or antibody levels and flare-ups in 91% of PANDAS cases, and only 39% of children diagnosed in 2008 met the original five criteria. A 2017 Swedish study found that 86% of healthy controls tested positive on the Cunningham panel, a commercial blood test. That is not a diagnostic test at that point. It is close to a coin flip with an invoice attached.

The real guideline ladder looks like this: treat any documented active infection first, then psychiatric and behavioral care such as exposure and response prevention, then anti-inflammatory treatment scaled to severity. IVIG has the strongest evidence on that ladder, with a 60% mean symptom reduction in an NIMH study. At the other end sits an immunosuppressant cancer drug used outside of trials, and a pediatric neurologist said of it, "This is a very powerful medication, and somebody is going to get hurt." Same diagnosis, very different outcomes, depending on which clinician you end up in front of. Five states have passed insurance coverage laws for PANDAS treatment despite the evidence gaps.

Why it belongs in this episode: a contested diagnosis grows a market fast, and some families who believe a practitioner's claim stop pursuing the autism plan entirely.

Leucovorin: a promise and a much smaller approval

In September 2025 the President announced a treatment for autism. It was not a new drug. Leucovorin, also called folinic acid, is a prescription form of vitamin B9, FDA-approved since 1983 to protect healthy cells during chemotherapy and to treat certain anemias. The theory is that some autistic children have antibodies that block folate from reaching the brain, producing cerebral folate deficiency, and that leucovorin may get around the blockage.

The evidence for autism is small and short. It is not the large, multi-site, rigorously blinded trials the FDA normally requires before approving a broad new use. The American Academy of Pediatrics says the existing studies have fewer than 100 participants each, there are no large multicenter trials, and there is "insufficient evidence to support prescribing leucovorin for autism in the absence of" documented cerebral folate deficiency.

At the announcement, the FDA Commissioner said "hundreds of thousands of kids, in my opinion, will benefit," potentially "20% to 50% of kids with severe autism." The pushback was immediate. The Coalition of Autism Scientists said it is "premature to claim that leucovorin is an effective treatment for autism." Then, on March 10, 2026, the FDA approved leucovorin for one rare genetic form of cerebral folate deficiency, covering about 70 children. It does not cover autism generally. HHS later clarified that the Commissioner's earlier comments described a different, antibody-driven form of the condition, not the genetic one the approval covers.

Confirming either form is not simple. The genetic form has historically required a lumbar puncture to measure folate in spinal fluid, and there is no FDA-cleared blood test for the antibody form. If you are considering leucovorin, that is a conversation for your child's physician, not a supplement aisle or a telehealth ad.

Conflicts of interest and the guardrail that came down

Now back to where we started. HHS removed the FDA's consumer warning page on dangerous autism treatments. The page had stated plainly that "products or treatments claiming to cure autism are deceptive and misleading, because there is no cure for autism." HHS's stated reason for pulling it was "routine clean up of dated content." HHS called the criticism of the removal "false."

The reactions came fast from serious institutions. Dr. Helen Tager-Flusberg called it "a devastating blow." A representative of the Autistic Self Advocacy Network said, "People are still being preyed on by these alternative treatments, like chelation and chlorine dioxide. Those can both kill people." When researchers, clinicians, and an autistic-led advocacy group all agree, this is not a split between parents and self-advocates.

The same story is still moving. On September 18, 2026, Reuters reported that HHS Secretary Robert F. Kennedy Jr. named a new chair of the Interagency Autism Coordinating Committee, the body that helps set federal autism research priorities. The new chair, Dr. John Gaitanis, is the director of the NIH's child health institute and a longtime public proponent of leucovorin as an autism treatment. A company that launched in April with a leucovorin telehealth platform lists him as a co-founder in its launch release. I will follow up in a future episode once we see what he does in the role.

The neurodiversity view

I told you I would come back to the argument sitting underneath all of this. Many autistic adults would say the harm is not any single treatment on this list. It is the premise under the ones sold as a cure: that autism is the problem to be fixed. The Autistic Self Advocacy Network states that "disability is a natural part of human diversity" and that autistic people should be supported "to live good lives."

A lot of parents are not thinking about identity or philosophy at all. They are thinking about a child who cannot tell them where it hurts. Both are true at the same time, and I am not going to pick one to make this episode simpler.

My own opinion is that this partly sounds like semantics. An infection gets treated. A folate transport problem confirmed by a lab gets treated. A child in gut pain gets treated. But bleach, chelation, dewormer cleanses, and stem cell flights sold as a reversal are not that. Many parents have cried to me about how desperate they are for their child to stop hurting themselves, and to be able to say what they need.

Four questions to ask about any treatment

Here is the test I would run on anything:

1. Is there a published, peer-reviewed study behind this, or just a dissertation and a product name?
2. Does anyone selling it have a financial stake in the result?
3. Is the "before and after" you are being shown a single testimonial, or an actual controlled trial?
4. Would the people who developed it tell you to try it without their supervision?

I run it against a real example: a gut bacteria urine test that came out of a university lab. It claims 90% of autistic children tested had elevated markers. That figure and a single case example have not been independently published in a peer-reviewed journal. They come from a dissertation attached to a commercial product. I am not saying the test is fake. I am saying it has not answered these four questions yet, and that gap is what separates evidence from marketing, whether or not the conflicts are disclosed.

Run the same four questions back through the hour. IVIG for PANDAS clears them. The gluten-free research clears them, barely. The urine test, the GAPS diet, and everything on the old FDA list fail. Leucovorin is still working through them, because that story is not finished.

Why parents say yes

There is no cure for autism. That is the first fact the fad market has to erase, because the product only sells if autism is framed as a toxin, a parasite, or a "blocked" child who can be recovered if the parent is brave enough.

Here is why it works. Sellers use urgency: "critical window," "too late if you wait." Waitlists for evaluations and therapy are long and fragmented, so the first person to answer at 11 p.m. is often a Facebook group, not a developmental pediatrician. "Natural" gets treated as a safety label, even though chelation and bleach are not kale. Testimonials beat trials on purpose, because a before-and-after story of one child is easier to feel than controlled evidence. In group settings, doubt gets framed as not loving your child enough, and side effects get renamed "healing reactions."

Real medical gaps also get stretched into a theory of everything. Autistic children do have higher rates of GI problems, sleep issues, seizures, and anxiety, and those deserve ordinary workups. The leap from "this child is constipated" to "autism is parasites and metals" is the scam.

False hope has costs. It burns the years that matter, trains parents to misread their own child, can injure the body, can drain a household, and can isolate a family from real help. The money could have paid for speech, OT, or a safe communication device.

Red flags and what a real plan looks like

These are almost always about the product, not the parent:

• Claims to cure, recover, or reverse autism
• One product for autism, cancer, COVID, and parasites
• "Doctors don't want you to know" plus a checkout link
• Pain or illness reframed as proof it is working
• Pressure to start now or lose the window
• Labs sold by the same clinic that sells the protocol

None of that means you should not be doing something. Hard work is not glamorous. Behavior support, communication, sleep, nutrition that actually feeds your child, and treating constipation or seizures are all important, and none of it is an overnight fix. Every treatment in this episode sells the same thing under different packaging: a single fix, from one product, one clinic, or one government announcement, with nobody else in the room checking the work.

The alternative is not a better product. It is a team that has to actually agree with each other before anything gets tried on your child.

I do not believe parents are intentionally causing harm. I think they love their children and want desperately for them to sleep through the night, stop hurting themselves, and express what they need. The page that used to warn you is gone, so for now the warning has to come from people like me. Please do not turn me off because you think I do not care. I care deeply, and I am working on solutions to the systemic problems that keep families from a true team.

Tell me in the comments: what treatment have you been pitched, and what made you trust it or walk away?
