Ozone therapy is a form of alternative medicine treatment that believes to increase the amount of oxygen to the body through the introduction of ozone gas into the body. There is some evidence to suggest it can treat various diseases including cancer, AIDS, multiple sclerosis,  rheumatoid arthritis, hepatitis B and C, diabetes, infected wounds, circulation disorders, and infectious diseases such as Ebola. Ozone therapy is also used for “slipped disks” in the spine, heart disease, cancer, an eye disease called macular degeneration, and Parkinson’s disease. It is also used for treating abscesses and other signs of infections and is sometimes used to stop dental cavities from progressing.
Historically it has been around for a while, in 1856 ozone was first used in a health care setting to disinfect operating rooms and sterilize surgical instruments. By the end of the 19th century ozone was being used to disinfect drinking water of bacteria and viruses. In 1892 The Lancet published an article describing the administration of ozone for the treatment of tuberculosis and it was used during the First World War to disinfect wounds.
Ozone is a naturally occurring chemical that consists of three oxygen atoms. Ozone is a powerful oxidizing agent and high concentrations of ozone can be toxic to living organisms and is considered a major source of pollution. However, small ozone doses are thought to increase some naturally occurring antioxidants in the body which are thought to help to fight off cancer, viruses and bacteria and benefit the body in other ways as well.
Ozone therapy involves the introduction of ozone into the body via various methods, usually involving mixing the ozone with various gases and liquids and injecting this into the body, either via a muscle, under the skin or directly into a vein. Ozone can also be introduced via autohemotherapy, in which blood is drawn from the patient, exposed to ozone and re-injected into the patient.
However the safety of ozone has not been studied enough to know if it is safe or what side effects it might cause. Ozone is known to be toxic when inhaled from polluted air in large amounts and when given intravenously by injection, it can cause serious side effects including blood clots in the lung. Ozone produces free radicals, an over-abundance of which is known to cause oxidative stress and cell damage, and is thought to worsen some degenerative diseases. The development of hepatitis and death has also been reported.
A group of doctors who are experts on oxidative therapy have travelled to Sierra Leone as they believe that ozone therapy is an inexpensive and very safe treatment for the devastating disease, Ebola that has recently become widespread. They travelled there at the end of 2014 to teach healthcare workers to administer the treatment, even the President of Sierra Leone publicly had the treatment.
They believe that ozone is extraordinary in terms of its anti-infective and antiviral action, all that is needed is the machine and a needle, making it uncostly and it has virtually no toxic side effects, which makes  it perfect for both prevention and treatment of all sorts of infections and viral afflictions, including Influenza and Ebola.
With bacteria, ozone works by puncturing the membrane of the bacteria, causing it to spill its contents and die. It also inactivates viruses, and does so 10 times faster than chlorine. It is believed that ozone is perhaps the most powerful natural oxidant in the world, and that it has the advantage of stimulating the immune system, and modulating it—either up or down depending on what your system requires.
Unfortunately the treatment being given over in Sierra Leone was stopped due to scepticism and a lack of concrete scientific evidence to back up the treatments even though there were many reported cases of infected individuals recovering from Ebola after having ozone treatment.
Hopefully more scientific studies will be carried out so as to ascertain once and for all whether ozone therapy could be used to treat a wide variety of diseases and medical complaints and could potentially in the future be a cheap, effective, low-risk, low side-effect method to treat so many different ailments and infections and become a ground-breaking discovery. It would be extraordinary if it was found to be a treatment for common widespread infections such as the Flu and Ebola and could eradicate these diseases.
