Natural Ways To Treat Diarrhea And Upset Stomachs
Yarrow

Although many may not be aware of its health benefits, yarrow contains various substances such as flavonoids, polyphenols, lactones, tannins, and resins that may help decrease the amount of acid within the stomach. These substances act on the main digestive nerve, the vagus nerve, to try and reduce stomach acid and calm the stomach’s lining. With a reduction in stomach acid, a patient has a reduced chance of experiencing heartburn and indigestion. To remedy an upset tummy, individuals should try ingesting young yarrow leaves raw in a salad or cooked in a meal, or as a hot tea by adding one or two teaspoons of dried or ground yarrow leaves or flowers to boiling water.
Basil

Not only is this classic herb delicious in many meals, but basil also contains many active substances that help to reduce gas and flatulence, increase appetite, alleviate cramping, and improve a person's overall digestion. Just like cinnamon, basil contains eugenol, an active compound that can help reduce the quantity of acid in the stomach, as well as high levels of linoleic acid. It also has anti-inflammatory properties. Those who wish to use basil should try adding one or two teaspoons of dried or fresh basil leaves to meals to lessen the symptoms of an upset stomach, or make a tea with half a teaspoon of dried or fresh leaves.
