Wolfheart, did you say coffee enema? I doubt anyone will openly admit first hand experience now...

Anyway, if it has worked for many, let's not worry about it.
There are so many strange medical practices that seem to work but there is no scientific proof for them. At least nothing that can convince modern scientist, but that doesn't mean they don't work at all. Science it yet to discover it. Here is a strange example from my family.
My mother has had chronic migraine since she was 15. If ever she doesn't get to sleep on time at night, next day she starts suffering from severe headache for next 2-3 days. I grew up watching this phenomena. During that time, she would be bed-ridden, can't eat properly, vomits all the time, it is hellish, the whole home environment used to have gloomy pall whenever my mother is struck with migraine. Thanks to that I learnt to cook emergency food for the family so that we can get past those days. No medicine ever worked, not allopathy, not ayurveda, not homeopathy, not yoga, not anything. Every damn cure has been tried, but nothing has ever worked.
After my wedding I have rarely stayed with my mother for long durations, but I used to hear about her occasional migraine incidences even then. However, last few months my parents stayed with me to take care of my older son since my wife was away in Bangalore for my younger son's autism treatment.
During these last few months, I realised that my mother didn't suffer migraine even once. So I asked about it.
Me: Mom, I don't see you suffer from migraine anymore...
Mom: Well, I haven't had a single episode since 4 years, not since I turned 70.
Me: That is wonderful, you mean migraine stops after a certain age?
Mom: I suffered it for 55 years, no it doesn't go away with age. I was treated for it.
Me: Wow, so something finally worked, who was it, what was it?
Mom:Um, it was Ganapathy Bhat from Puttur.
Me: Ganapathy Bhat from Puttur? But he is a retired Bank Manager, dad's junior.
Mom: Well, there was a traditional treatment that was passed on for generations in his family. He had learned it from his father. Few years back, he offered to use it. Since he is a family friend for 35 years, I decided to trust him even though he is no doctor.
Me: What was the treatment?
Mom: He looked for a nerve behind my head and pressed it very hard. It pained for couple days, and after that nothing. Next time I lost sleep, I didn't get migraine. In fact I never got migraine after that, not since 4 years.
How can this be explained? I can't think of a way, don't think any modern doctor can. But my mother doesn't care whether it can be explained or not, she got cured, that's all she cares. We don't even know the name of this treatment or the branch of medicine it belongs.
Can we ask Ganapathy Bhat from Puttur? Not anymore, he expired in a tragic cycle accident couple years back. May he rest in peace.
