Medical Ozone Therapy

Oxidative Therapypreliminary evidenceClinic Only
IVRectalTopicalInhalation-indirect

Medical ozone (O₃) is generated by passing pure oxygen through a calibrated ozone generator. The most studied cancer-relevant protocol is Major Autohemotherapy (MAH) — drawing 100–200 ml of blood, mixing with ozone, and reinfusing it. Ozone oxidises lipids in blood, generating ozonides (lipid peroxides) that act as secondary messengers, stimulate immune function, improve tissue oxygenation, and exert selective cytotoxicity against cancer cells. Used extensively in Germany, Italy, Russia, and Cuba as integrative oncology adjunct.

Mechanism of Action

Ozone reacts with blood lipids and proteins to form ozonides and lipid oxygenation products (LOPs). These LOPs act as signalling molecules that activate Nrf2 (antioxidant pathway), stimulate red blood cell flexibility and oxygen release, activate NK cells and macrophages, and generate controlled oxidative stress selectively in metabolically active (cancer) cells. Low-dose ozone preconditioning can also reduce radiation and chemotherapy side effects.

Protocols & Dosing

Major Autohemotherapy (MAH)

100–200 ml blood drawn, mixed with medical-grade ozone (20–80 μg/ml), immediately reinfused IV over 20–30 min. 10–20 sessions, 2–3x per week at ozone therapy clinic. Most studied protocol.

Rectal Ozone Insufflation

200–500 ml medical ozone gas introduced rectally via catheter. Absorbed through intestinal wall. Done at home or clinic. Used for colorectal cancers and gut health support.

Local / Topical Ozone

Ozone bagging around affected limb, ozonated water, or ozonated oils applied to wound/tumour area. Used for skin tumours and wound healing post-surgery.

Prolozone Injection

Ozone injected into tumour-adjacent tissue (joint or soft tissue). Performed by physician only.

Cautions & Contraindications

  • NEVER inhale ozone gas directly — causes severe lung damage (ozone is a respiratory toxin)
  • Must use medical-grade ozone generators and pharmaceutical-grade oxygen — industrial ozone is toxic
  • Contraindicated in: favism (G6PD deficiency), acute hyperthyroidism, thrombocytopenia, coagulation disorders
  • Contraindicated in active haemorrhage or convulsions
  • Only available at certified ozone therapy clinics under physician supervision
  • Regulatory status varies by country — legal in Germany, Italy, Russia; restricted in USA
