If you have been dealing with problems of diarrhea, it is important to hydrate and fight off any potential bacteria that may be causing the issue. Lemons are a natural way to do both of these, as the acid content of lemons help to kill all bad bacteria in the gut and lemon juice mixed with water helps to hydrate the cells in the body. With that said, consider having some fresh lemon cocktails to help alleviate your symptoms of diarrhea. Mix together a teaspoon of ginger juice, lemon juice and a quarter teaspoon of cayenne pepper together. Once mixed, drink the mixture and repeat up to three times daily for best results.
