Ozone Therapy is a complementary medical approach that uses ozone, a reactive form of oxygen, in controlled applications. It has been studied for conditions such as joint pain, wounds, dental problems, and some skin disorders. However, current evidence does not establish ozone therapy as a proven treatment for most diseases. A 2026 umbrella review found that available clinical evidence is inconsistent and generally low or very low certainty.
What Is Ozone Therapy?
Ozone therapy involves using ozone (O₃) in a controlled medical or clinical setting. Unlike the oxygen people breathe, ozone is a highly reactive gas. Researchers have investigated whether carefully controlled exposure may influence inflammation, oxidative processes, microorganisms, or tissue healing.
The term can describe several different approaches, including topical applications, ozonated water or oils, and certain injection-based procedures. Because these methods differ substantially, results from one type of treatment cannot automatically be applied to another.

What Conditions Has It Been Studied For?
Ozone therapy has attracted research interest across several areas of medicine. Studies have examined its possible role in knee osteoarthritis, chronic wounds, dental conditions, skin disorders, and some musculoskeletal problems.
For knee osteoarthritis, reviews have reported possible short-term pain improvement compared with placebo, but researchers have also noted major differences between studies and insufficient evidence to show that ozone is better than established treatments.
Research on chronic wounds has produced some encouraging findings, but newer high-level evidence is more cautious. The 2026 umbrella review found that ozone was not clearly superior to control treatment for diabetic foot ulcer healing or reducing ulcer area.
Skin research has also suggested potential benefits for certain conditions, but systematic-review authors have emphasized methodological limitations and uncertainty about safe treatment standards.
Overall, promising findings should be viewed as research evidence rather than proof that ozone therapy can treat or cure a disease.
Is Ozone Therapy Safe?
Safety depends heavily on how ozone is administered. Ozone is not a harmless form of oxygen. NIOSH reports that ozone exposure can cause coughing, headaches, dry throat, shortness of breath, chest discomfort, and fluid in the lungs; higher exposure can cause more serious effects.
For this reason, ozone gas should not be inhaled as a health treatment. The FDA has also raised safety concerns about ozone-generating devices when ozone exposure may occur during use.
For medical applications that do not involve inhaling ozone, safety evidence is less definitive. The 2026 umbrella review found that safety outcomes were inconsistently reported and that available evidence was insufficient to make firm conclusions about adverse events across the different treatments studied.
Anyone considering ozone therapy should discuss the specific procedure, potential risks, alternatives, and evidence with a qualified healthcare professional. It should not replace proven treatment for a serious medical condition.
What Does Current Research Really Say?
The strongest overall message from recent research is that Ozone Therapy remains an area of investigation rather than a universally established medical treatment.
A 2026 umbrella review assessed seven meta-analyses covering four clinical areas: chronic periodontitis, COVID-19, diabetic foot ulcers, and impacted third-molar surgery. The researchers found mixed results and rated the certainty of evidence as low or very low for all outcomes examined. They concluded that routine clinical use is not justified until better-designed trials provide stronger evidence.
This does not mean that every use of ozone therapy is ineffective. Some studies report potentially useful results, particularly for certain pain or dental applications. However, differences in ozone concentration, delivery method, patient groups, and study quality make broad conclusions difficult.
It is also important to distinguish scientific research from marketing claims. Statements that ozone therapy can cure cancer, replace conventional treatment, or provide guaranteed health benefits are not supported by the current evidence.
Conclusion
Ozone Therapy is being investigated for several medical applications, but its effectiveness and long-term safety remain uncertain. Some studies show potential benefits, while higher-level evidence remains inconsistent. Ozone inhalation can be harmful, so treatment should only be considered with appropriate professional guidance and should not replace established medical care.

FAQs
1. Is Ozone Therapy FDA approved as a general treatment?
No. FDA requirements apply to medical devices and claims involving ozone, and unsupported medical claims can violate federal requirements. There is no general FDA approval for ozone therapy as a treatment for diseases.
2. Can you breathe ozone during treatment?
Ozone should not be inhaled. NIOSH identifies ozone inhalation as a respiratory hazard and reports potentially serious effects from exposure.
3. What is Ozone Therapy used for?
It has been studied for conditions including joint problems, chronic wounds, dental conditions, and some skin disorders. Evidence varies considerably by condition and treatment method.
4. Can Ozone Therapy replace regular medical treatment?
It should not be used as a replacement for proven medical treatment. Because evidence remains limited for many applications, discuss any proposed use with a qualified healthcare professional.
