If you have bad breath, you can take some Yangyin Kouxiang Koufuye. Take it twice a day, 30 ml each time. It is recommended to have a light diet, eat more vegetables and fruits, drink more water, and pay attention to rest. Do not work overtime or stay up late. Avoid spicy and extremely cold foods. For severe bad breath patients, it is recommended to seek medical attention immediately and follow the doctor's advice for immediate treatment.
