The FDA is quite clear about ozone:
Ozone is a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy.
In fact, ozone is the primary ingredient of the air pollution known as smog. It’s a highly reactive gas that can do harm to the human body. When breathed in, ozone can cause damage known as “a sunburn inside your lungs.”
Ozone therapy can kill
One worry about ozone therapy is the possibility of air embolism caused by a gas bubble entering a place it shouldn’t go, for example a vein or an artery.
In 2015, two men were charged with murdering a woman who died after receiving “Octozone” treatment. The coroner ruled the death a homicide by air embolism.
One of many sham treatments marketed for “Chronic Lyme”
Those who have become convinced they have chronic Lyme, “toxic mold illness”, or other fake diseases often pursue harmful treatments in desperate attempts to feel better. In a 2015 scientific review, ozone therapy was among 30 “unorthodox” Lyme therapies without evidence for efficacy.
The CDC warns:
Antibiotics are the only known effective treatment for Lyme disease, but a quick search on the internet will introduce you to other untested remedies that claim to cure Lyme disease or chronic Lyme disease. These products—available online or from some health care providers—may be dangerous, deadly, or simply a waste of money.
According to former naturopath Britt Hermes:
Ozone therapy is at the same level of quackery as fake cancer vaccines made from urine and illegal cancer drugs imported from overseas.
What is ozone therapy?
Ozone therapy can mean different things. Some quacks become convinced ozone gas is magic. They will tell people to breathe it in or even administer it vaginally or rectally. Some will dissolve tiny amounts in oil or water and drink it.
The most dangerous type of ozone therapy involves removing blood from a patient, exposing it to ozone, and then re-injecting it. This is called autohemotherapy and involves risks but no known benefit, especially for Lyme disease. Sometimes they also expose the blood to ultraviolet light.
