Ozonated products – particularly ozonated oils – represent one of the most accessible and well-evidenced forms of ozone therapy. These products capture the therapeutic benefits of ozone in a stable, easy-to-use form that can be applied at home under veterinary guidance.
This guide explains how ozonated products work, the different types available, their applications in veterinary medicine, and practical guidance for use.
How Ozonated Products Work
The Science
When ozone gas is bubbled through vegetable oil, it reacts with the unsaturated fatty acids in the oil. This creates a complex mixture of compounds called ozonides, along with other oxidation products including aldehydes and peroxides. These compounds are relatively stable in the oil matrix and release their oxidising power slowly when applied to tissues.
The key mechanisms include:
Sustained antimicrobial action: Unlike ozone gas which dissipates quickly, ozonated oils release reactive oxygen species gradually, providing prolonged antimicrobial activity over hours to days.
Tissue stimulation: The mild oxidative stress from ozonated oils activates beneficial cellular responses including increased growth factor production and enhanced immune cell activity.
Improved healing environment: Ozonated oils create conditions that favour healing — reduced bacterial load, improved oxygenation, and stimulated tissue repair.
Ozonation Degree
The therapeutic activity of ozonated oil depends on its ‘ozonation degree’ — how much ozone has been incorporated. This is typically measured by peroxide value (PV) or iodine index reduction.
Higher ozonation = more potent antimicrobial activity
Lower ozonation = gentler, suitable for sensitive areas
Quality products specify their ozonation level
Different ozonation degrees may be appropriate for different applications; heavily infected wounds may benefit from higher ozonation, while maintenance use may suit lower levels.
The most widely studied and used ozonated oil. Olive oil’s fatty acid profile creates stable ozonides with excellent antimicrobial and healing properties.
Broad-spectrum antimicrobial (bacteria, fungi, some viruses)
Water saturated with ozone provides immediate antimicrobial action but has a short active life; ozone dissipates within minutes to hours depending on conditions.
Ozonated oils are excellent for home wound care under veterinary guidance. They help keep wounds clean, fight infection, and support healing. Common uses include:
Minor cuts and abrasions
Post-surgical wound care
Dermatitis and skin infections
Slow-healing wounds
Wounds in diabetic or elderly animals
Apply a thin layer of ozonated oil to cleaned wounds 1-2 times daily. Cover with a light dressing if needed to prevent licking.
Clinical Detail
The evidence for ozonated oils in wound healing is robust:
Store in a cool, dark place (refrigeration extends shelf life)
Keep containers tightly sealed
Avoid contamination — don’t double-dip
Check expiry dates and ozonation levels
Discard if smell or appearance changes significantly
When to Seek Veterinary Advice
While ozonated products are suitable for home use in many situations, consult your vet if:
Wounds are deep, large, or near vital structures
Signs of systemic infection (fever, lethargy, loss of appetite)
No improvement after several days of treatment
Wound appears to be worsening
You’re unsure whether ozone is appropriate for the condition
Not a Replacement for Veterinary Care
Ozonated products are valuable tools but don’t replace proper veterinary assessment and treatment. Serious infections, surgical conditions, and systemic illness require professional care. Use ozonated products as part of a treatment plan developed with your vet.
Evidence Summary
Ozonated oils have one of the strongest evidence bases in veterinary ozone therapy. Key systematic reviews and meta-analyses confirm:
Effective antimicrobial action against bacteria, fungi, and some viruses
Enhanced wound healing compared to untreated controls
Efficacy against antibiotic-resistant organisms including MRSA
Good safety profile with minimal adverse effects
Multiple mechanisms supporting tissue repair
The research spans in vitro studies, animal models, and clinical applications in both human and veterinary medicine.
