We can enhance human immunity by adding trace elements of selenium, vitamin E and beta carotene at the same time, i.e. by taking the medicinal supplement of malt selenium and vitamin E tablets directly, supplemented by the dietary supplement of eating more mushrooms, seafood, animal liver, carrots, purple potatoes and other foods. Enhanced human immunity by sweeping away free radicals, preventing immune cells from peroxidation and keeping them active will enhance the activity of immune cells such as white blood cells, T lymphocytes, macrophages and phagocytes in a short period of time, which in turn will strengthen the killing power of immune cells against HPV virus and speed up their speed of eliminating HPV virus, and if HPV positive, it will help speed up the conversion. In addition to using various nutrients to fully enhance the immune system’s ability to kill HPV, women who have cervicitis and are also infected with HPV should pay special attention to a regular diet, go to bed early and wake up early, eat a balanced and light diet, refrain from smoking and drinking, and be optimistic in order to maintain normal immunity in the long run. If coupled with regular cervical cancer screening and annual rechecking for high-risk patients, the layers of control will allow other types of HPV virus to escape seamlessly.
