Here is a short excerpt from the article.
Oil of Oregano is a Natural Anti–Inflammatory Medicine
An article published in Phyotherapy Research describes how oregano oil surpassed anti–inflammatory drugs in reversing pain and inflammation and that it is nearly as powerful as morphine as a painkiller.
In fact all Inflammation & Infection are Natural Healing Processes created by the body in order to maintain its health as best it can in spite of poor nutrition, an overload of toxins, damaging foods, etc.
Helps Arthritis, Fibromyalgia, Bursitis, Carpet Tunnel, Sore Muscles, Sports Injuries, Backaches, etc.
Oil of Oregano is helpful because it penetrates the skin and reaches as far as the synovial fluid in joints, which helps alleviate arthritis, bursitis, carpal tunnel syndrome, sore muscles, sports injuries, and backaches because it helps pull toxins out. All forms of arthritis, including fibromyalgia, are caused by toxins—see Arthritis, Fibromyalgia, Rheumatoid Arthritis, Tendonitis & Related Diseases.
Rub a few drops of the mixture (50/50 mixture of oil of oregano and extra virgin olive oil) into the skin covering the affected areas.
