When I was a child, my grandma told me some folk remedies for bad breath. Because I often had bad breath when I was a child, my grandma always said that I was a little smelly cat, and then she used the following little folk remedies to help me reduce my bad breath, so These methods can only provide relief. I suggest you use sword beans to condition it, which may be more helpful. 1. Eat fresh vegetable leaf juice. Take fresh green cabbage leaves (or radish leaves, lettuce leaves), rinse them with water, rinse them with cold boiled water, dry them, then chop them with a knife, and use a juicer to extract the juice. You can also mash it in a container, squeeze the juice, and then filter it with clean gauze. You can add a little cold water when taking it, and drink 1 cup every morning and evening for two weeks. It will be effective. 2. Eat lettuce or leaves raw often. Cut the lettuce into slices, mix it with an appropriate amount of oval salt, let it sit for a while, drain the salt water, add high-quality soy sauce and a little MSG, and then pour a few drops of sesame oil. It tastes good as a cold dish. Chop the lettuce leaves into small pieces, salt them with a little salt, and then pour them with sesame oil. It can be used as a dish and can also treat bad breath. 3. Decoction 9 grams of Patchouli leaves and 3 grams of Acorus and take it twice a day, one dose per day. 4. 30 grams of pure white honey, mixed with warm water, simmered once. 5. Grind 3 grams of licorice, 6 grams of Ligusticum chuanxiong, 9 grams of cloves, and 15 grams of Angelica dahurica into fine powder, mix evenly, and make into pills with honey, swallow them twice a day.
