My partner and I were traveling in Canada a few years back. We stopped for some dinner at the only restaurant in the area, a divey little Indian food place. The food was less than fresh. Later that night and all the next day we were racing to the bathroom with food poisoning. We were miserable and since this was the very beginning of our vacation we were a little depressed.
After laying in bed for hours, miserably, I remembered that I had packed some Peppermint oil. We figured at that point we had nothing to lose, so we broke it out. We were having a hard time keeping anything down so we applied it first to our stomachs. After about a 1/2 an hours, our stomachs had settled enough to drink some water and rest. We put 2 drops in a glass of water and drank it. After an hour we were done running to the bathroom. We kept sipping at another glass of peppermint water (2 drops to a glass) and were soon up to leaving the hotel room. Our vacation was saved! All thanks to Peppermint oil.

***A note about this oil: it is very important to only use therapeutic, food grade essential oils if you are either applying to the skin or consuming the oil. Oils that are not low pressure, steam distilled contain chemicals that are used to strip the oils from the plants, these adulterated oils can burn you. This is the difference between a perfume oil and an essential oil. I use Young Living oils because I know I can count on the purity and have never had a negative reaction to.***
