One of my favorite travel stories is actually from a trip to India and perfectly covers this:
After about two weeks in India and a week in New Delhi, I was having some issues with "Delhi Belly" and things weren't quite flowing the way they normally would. I had rested, taken anti-diarrhea mediation, etc. and it wasn't great, but I was managing. I traveled up North to the Palampur region and signed up for yoga classes. I ended up being the only one who signed up, so they became one-on-one lessons.
Within about ten minutes, after doing some hands-on adjusting, the instructor asked me if I was feeling okay and if I was having stomach problems. I explained that I hadn't been feeling great and he told me he could feel the issue: MY NAVEL WAS OFF-CENTER. I giggled (because I had to) and he launched into a big explanation of what that meant--my intestines were pushed to one side, so things couldn't flow. He "proved" it to me by measuring with a string and offered to help. I still didn't quite know what was happening, but of course, I said yes.
He punched me in one shoulder (I again started to laugh because it was just so odd to this Westerner), he tied string around my two big toes, we did a few specific yoga poses, and he gave me instructions (don't run, don't ride in the back of the bus, etc.) It was such a strange thing and my twenty-something self found it hilarious and fascinating.
But, I kid you not, I woke up the next morning feeling amazing. Everything was back to normal. I kept the string on my toes as long as I could, followed his instructions, and didn't have any more problems.
I've always been a "yoga person," but this made me a true believer in the healing power of Eastern medicine.
Epilogue: When I returned home, I went to dinner with an Indian friend and told the story. He interrupted me to launch into his own explanation of how important it was to have your navel centered. We then had a really interesting discussion about Eastern/Western medicine and how India was just starting to realize it needed both. It had been under English rule for so long and so many wanted to assimilate, that they forego their beliefs in Eastern medicine...but they're starting to come around and realize that a balance of both is needed.
This book was a nice reminder for me to explore natural medicine.
