People searching for EBOO therapy benefits usually want a straight answer: what might it do, and how good is the evidence? EBOO (extracorporeal blood oxygenation and ozonation) has been studied mainly for its effects on circulation, oxygen use and the body’s own antioxidant response. The research is real but small, and EBOO is not FDA-approved to treat any disease, so this page walks through what has been studied, what patients commonly report, and where the gaps are.

EBOO benefits at a glance
These are the areas researchers have looked at. They describe what was studied, not results you should expect:
- Circulation and small blood vessels. The best-known controlled trial of EBOO was in people with peripheral artery disease (PAD) and skin lesions on the legs.
- Oxygen delivery and use. Researchers have described how ozonated blood may influence how red blood cells release oxygen to tissues.
- The body’s antioxidant response. A brief, controlled oxidative signal is thought to switch on the body’s own antioxidant enzymes, an idea called hormesis.
- Immune signaling. Laboratory work suggests ozone-treated blood can shift some immune signals. How this translates to people is still unclear.
- Patient-reported wellbeing. In the PAD trial, patients also reported changes in pain and general wellbeing. These are subjective measures.
How EBOO is thought to work
During EBOO, blood is drawn from one arm, passed through a filter where it is exposed to a measured oxygen-ozone mixture, and returned through the other arm. Ozone reacts almost instantly with fats and antioxidants in the blood. Those reactions create short-lived messenger molecules.
A 2011 review by Sagai and Bocci proposed that this mild, controlled oxidative stress activates a protective pathway called Nrf2. Nrf2 switches on genes for the body’s own antioxidant enzymes, such as superoxide dismutase, glutathione peroxidase and catalase. The authors compare it to exercise: a moderate stress prompts the body to strengthen its defenses, while too much causes harm.
A separate 2011 paper by Bocci and colleagues described an inverted U-shaped dose-response curve for ozone in blood. In plain terms, too little does nothing, a moderate dose may be useful, and too much can be harmful. That is why dosing and screening matter, and why EBOO is a medical procedure rather than a wellness add-on.
What the research shows
Here is an honest summary of the published human evidence on EBOO specifically:
- Peripheral artery disease (2005). Di Paolo and colleagues randomized 28 people with PAD to EBOO or intravenous prostacyclin. The EBOO group showed greater regression of skin lesions and differences in pain, itching, leg heaviness and wellbeing. The authors found no measurable change in blood flow to the legs in either group, and suggested other mechanisms were involved. No side effects were recorded across the EBOO sessions in that study.
- Clinical overview (2005). A review in Redox Report by the same Siena group described the EBOO method, the laboratory markers they used to monitor patients, and the conditions they had tried it in. It is a summary of their experience, not a controlled trial.
- Device studies (2007). Laboratory work tested the gas-exchange filter used to ozonate blood during EBOO, focusing on efficiency and safety of the equipment.
Limits of the evidence
- Most EBOO studies come from a small number of research groups, largely in Italy.
- Trials are small, and there are no large, multi-center randomized trials.
- Much of the mechanism work is laboratory-based or comes from related techniques such as ozonated autohemotherapy.
- Protocols, doses and session counts vary, which makes results hard to compare.

What patients commonly report
People who explore EBOO often describe goals such as more steady energy, clearer thinking, or feeling less run-down. These are personal experiences and vary widely. Some people notice nothing. We share them so you know what people talk about, not as a promise of results.
Who may be a candidate
EBOO is usually discussed with adults who have long-standing concerns that standard care has not fully explained, and who understand that it is investigational. At Venturis, patients often ask about it in connection with:
These are conversation starters, not treatment claims. Whether EBOO is a reasonable option is decided only after a Good Faith Exam by licensed medical staff.
Who should not have EBOO
EBOO is not appropriate for everyone. People with G6PD deficiency, uncontrolled hyperthyroidism, active bleeding problems, pregnancy, severe anemia, or certain heart conditions are typically not candidates. Our full list is on EBOO Side Effects and Safety: Who Shouldn’t Have It.
What a visit looks like
- Listening consult. We start with your history and what has and hasn’t worked.
- Good Faith Exam. Licensed medical staff review your health, medications and screening labs before any treatment.
- Your session. EBOO is performed by licensed medical staff under our medical director. A session usually takes about an hour, and you are monitored throughout.
- Follow-up. We check in on how you felt and decide together whether to continue.
Safety and risks
Common, usually short-lived effects include tiredness after a session, bruising at the needle sites and lightheadedness. Less common risks include low blood pressure, vein irritation and reactions to the anticoagulant used to keep blood flowing through the filter. Ozone is never inhaled during EBOO. Risks are reviewed with you in detail before your first session.
Cost
Cost is discussed at consult, because session count depends on your plan. For what affects the total, see EBOO Therapy Cost: Pricing, Packages and Sessions.
EBOO benefits FAQ
What are the main benefits of EBOO therapy?
Research has focused on circulation, oxygen use and the body’s own antioxidant response. The strongest human data is a small 2005 trial in peripheral artery disease. EBOO is investigational, and individual experiences vary.
Is EBOO proven to work?
No. There are encouraging small studies, but no large controlled trials. EBOO is not FDA-approved to treat any disease.
How many sessions does it take to notice anything?
It varies. Some people notice changes after a few sessions and some notice none. Your plan and session count are set after your Good Faith Exam.
Is EBOO the same as ozone IV or 10-pass?
No. EBOO filters and ozonates a larger volume of blood in continuous circulation. See EBOO vs 10-Pass vs IV Ozone.
Can EBOO be combined with IV nutrients?
Sometimes. IV options such as glutathione IV or the IV menu may be discussed after your Good Faith Exam.
Do you see patients from Tulsa?
Yes. We see patients from Oklahoma City and surrounding areas, including Tulsa. All EBOO sessions take place at our Oklahoma City clinic.
