Ozone plus therapy is a type of alternative medicine that uses ozone gas to treat various conditions. The ozone gas is created by passing oxygen through an electrical current. This process creates a high concentration of ozone, which is then used to treat the affected area. The ozone gas is thought to have healing properties, and it has been used to treat a variety of conditions, including arthritis, back pain, and wounds. Ozone plus therapy is available as an in-office treatment or through home health care services.
