Ozone Therapy

Medical ozone therapy delivers controlled doses of an oxygen/ozone (O₃) mixture through various routes to enhance cellular oxygenation, modulate the immune system and support tissue repair. Backed by decades of clinical use and a growing scientific literature, it is one of the central tools of integrative and functional medicine.

Biological Mechanism

Ozone (O₃) is a reactive gas with one extra oxygen atom. On contact with body fluids it generates reactive oxygen species (ROS) and lipid oxidation products (notably 4-HNE and H₂O₂). At low concentrations these act as biological messengers, activating cellular protective responses — the Nrf2 antioxidant pathway, Hif-1α-mediated oxygenation and NF-κB inflammation-regulation systems.

Paradoxically, controlled doses of ozone reduce oxidative stress (hormesis), increase tissue oxygenation, improve erythrocyte flexibility (microcirculation) and stimulate immune cells. High doses, by contrast, can cause oxidative damage — dose calibration is critical.

Routes of Administration

Major ozone autohaemotherapy: 50–200 mL of blood is withdrawn, enriched with ozone in a sterile bag and returned. Provides the broadest systemic effect.

Minor ozone autohaemotherapy: a small amount of blood-ozone mix injected intramuscularly. Combines regional and systemic effects in a quicker session.

Intra-articular ozone: direct injection into knee, shoulder, hip or elbow joints — reduces intra-articular inflammation and supports cartilage. Intra-discal ozone (discolysis) in the spine is an alternative to surgery for disc herniation.

Rectal insufflation: rectal delivery of an ozone-oxygen mix — supports gut microbiome and produces systemic effects through absorption. Useful in IBS and GI inflammation.

Indications

The clinical scope of medical ozone has expanded dramatically over four decades of European and Latin American literature. Indications span musculoskeletal and neurology (chronic spinal pain, disc herniation, osteoarthritis, tendinopathy, fibromyalgia, neuropathy, migraine, MS adjunct); cardiovascular (peripheral artery disease, chronic venous insufficiency, microcirculation disorders); metabolic (type-2 diabetes and complications, especially diabetic foot ulcers); immune and infectious (chronic viral infections including HBV, HCV, long-COVID, recurrent URTIs); autoimmune (RA, ankylosing spondylitis, IBD, psoriasis); dermatology (eczema, acne, herpes, chronic ulcers); oncology supportive care (reducing chemo/radiotherapy fatigue, mucositis, nausea); dental, ophthalmology, sports medicine, gynaecology/urology; and longevity (mitochondrial support, hormetic regulation, anti-ageing programmes).

Safety and Protocol

Medical ozone has a strong safety profile when used correctly — direct IV bolus ozone injection is never performed. Contraindications include G6PD deficiency, active hyperthyroidism, anticoagulation and pregnancy. A standard protocol is 2–3 sessions per week, 10 sessions total, followed by individualised maintenance.
