Old Molecule, New Evidence: Chlorine Dioxide Shows Promise in Three Veterinary Cases
Three animals with limited options improved after treatment with chlorine dioxide. A new case series in the Journal of Independent Medicine documents what happened.
May 27, 2026
The FDA calls chlorine dioxide “a dangerous bleach.” Millions of people drink low doses of it every day in treated tap water. And clinicians and veterinarians have been quietly using it for years to treat conditions that conventional medicine couldn’t resolve.
A new case series in the Journal of Independent Medicine puts clinical outcomes on the record for the first time in veterinary medicine.
Teresa Carr, a veterinarian with 30 years of clinical experience, and Mitchell Liester, MD, an adjoint assistant professor in the Department of Psychiatry at the University of Colorado School of Medicine, documented what happened when they used chlorine dioxide protocols on three animals that had run out of conventional options. A dog with suspected liver cancer. A cat with an infection that wouldn’t respond to antibiotics. A dog with a large, painful mammary tumor. All three improved.
“I began independently researching alternative therapies for patients with more complex conditions.” — Teresa Carr

What Chlorine Dioxide Is
Chlorine dioxide is a selective oxidant first synthesized in 1811. This is not the stuff you accidentally gulped at the swimming pool as a kid. It is a distinct molecule with a different mechanism of action: it selectively oxidizes specific amino acids in microbial proteins, disrupting their function and replication. That gives it broad-spectrum antimicrobial activity against bacteria, viruses, fungi, and parasites.
“Chlorine dioxide was synthesized over 200 years ago, but was primarily used as a water treatment agent. It also has broad spectrum antimicrobial activity against bacteria, viruses, fungi, and parasites.” — Mitchell Liester
Regulatory agencies have approved it for water treatment, food safety, and medical equipment sterilization. The antimicrobial properties are not in dispute. What’s been missing is formal clinical investigation.
The human data that does exist is promising. Studies have documented improved glucose control, reduced inflammation, enhanced wound healing, and activity against antibiotic-resistant pathogens. A case series showed complete resolution of treatment-refractory diabetic foot ulcers, with one patient achieving sustained medication-free glycemic control for three years.
The Safety Question
The FDA labeled chlorine dioxide “a dangerous bleach” during the COVID pandemic and pursued criminal enforcement against people promoting its use. Carr and Liester argue that label was based on high-dose misuse, not on the low-dose therapeutic protocols practitioners are actually using.
“The FDA during the COVID pandemic labeled chlorine dioxide a dangerous bleach. Now, this was based on very high doses being misused, not on the low doses that have been demonstrated to be safe.” — Mitchell Liester
The safety data at low doses tells a different story:
- The EPA established a no-observed-adverse-effect level of 3 mg/kg/day for oral chlorine dioxide
- Phase I and II clinical trials for ALS confirmed that IV sodium chlorite at doses up to 3.2 mg/kg/day was safe and well-tolerated, with no serious adverse events
- Millions of people consume low-dose chlorine dioxide daily in municipal drinking water
- In these three veterinary cases, no adverse effects across enema, oral, and intratumoral routes over treatment periods ranging from 10 days to 8 months
Calling this compound “a dangerous bleach” while millions drink it daily is, as the authors put it, like labeling chemotherapy a poison based solely on high-dose toxicity.
Why the Evidence Stays Thin
If the safety data is there and practitioners are already using it, why does the evidence base remain so limited?
The answer is structural. Chlorine dioxide cannot be patented. That means no pharmaceutical company has a financial incentive to fund the controlled trials that regulators require for approval. Regulators prohibit its therapeutic use because those trials don’t exist. And the prohibition makes it harder for researchers to generate the data that would justify lifting it.
“This compound is not patentable, and therefore it’s unlikely that pharmaceutical companies will want to fund further research.” — Mitchell Liester

The treatment consisted of increasing the concentration in cups of drinking water to levels above those typically used solely for water purification. They rapidly cured 154 malaria patients within two days.
