Gynecological ozone is harmless to the human body and is performed by a special machine that converts pure water into ozone atomization, which has a bactericidal and anti-inflammatory effect. When women suffer from various vaginitis, they can be treated with ozone and the treatment time is controlled to about 10 minutes. First, the vulva and vagina are rinsed with sterile pure water, and then the ozone is atomized inside the vagina to kill the bacteria in the vagina. This ozone can gradually decompose when it meets the air, and no allergic reaction will occur during the treatment with ozone. After 3-5 treatments for vaginitis, the symptoms of acute vaginitis can be well relieved and later women can place medication in the vagina to have a consolidating effect on the treatment. Ozone is a kind of physical therapy, which is widely used in gynecological clinics.
