I was too a very skeptical person, until I got a hormonal production disorder (I really don know its name in english, maybe later i can find a translation) that Western medicine said was impossible to cure and had to be countered with massive doses of neutralization of hormone medicines that would basically cripple me completely forever. I gave a shot and tried acupuncture since even death was better than those side effects. In 2 months the disorder was completely under control without any changes in my life but acupunture. The exams shown a reduction on the hormone production of more than 70%. I tough, ok that must be coincidence... stoped the treatment. Few months later the issue was back. Restarted the treatment and 1 month later was all under control again.... Even the doctors said to me, forget western medicie and stick to what is working.
Since then I tried acupuncture for a lot of things, including issues that western medicine never was able to cure me like allergic reactions etc. I am still quite skeptical about almost everything, but I was faced with undeniable evidence that it has some VERY interesting results.
People should spend less time trying to proof its or its not BS and more time trying to understand how to make people life better! And I pity the poor should that had the same diagnostics as me and went for the western "fully scientific" treatment.
Medicine should be about saving people and making them feel better! Not about having reason about anything! Fool is the one that speaks without having real experience about it. Fool is the one that condems others to suffering just because the better path doe snot match his own beliefs. That is basically the same thing as religious fundamentalist.
