Ozone has a strong oxidizing ability, and when it is injected into the nucleus pulposus of the herniated disc, it can instantly oxidize the proteoglycans in the nucleus pulposus and destroy the nucleus pulposus cells, so that the function of proteoglycans is lost, the cells produce less proteoglycans, and the osmotic pressure of the nucleus pulposus cannot be maintained, resulting in the loss of water and atrophy, thus reducing the pressure in the disc, eliminating the symptoms and achieving the purpose of treatment. At the same time, ozone has anti-inflammatory and analgesic effects and can eliminate sterile inflammation in the nerve root, thus achieving a radical cure. Ozone therapy is safe, less invasive, easy to operate and has no significant complications. The clinical application of medical ozone has been very common in foreign countries, especially in Europe, mainly used in the treatment of trauma and refractory ulcers (such as diabetes), adjuvant treatment of cancer, treatment of lumbar intervertebral disc and bone and joint diseases, anti-aging of anti-free radicals and treatment of stroke and other diseases, and the efficacy of clinical application has been fully affirmed. In recent years, medical ozone has made a promising breakthrough in the treatment of viral hepatitis.
