Alternative medicine does work more slowly. The trouble for most Westerners is they only try to use an acupuncturist, for example, after they've tried everything else that hasn't worked, so the delay in starting holistic treatment is substantial. By that time their system is so out of whack, it takes even longer for the natural healing balance to be restored.
Also, most expect the "one and done" treatment. They aren't always prepared for the idea of coming back once a week for a month, out of pocket. And it's NOT a permanent cure. The imbalance was caused by something specific, and if you insist upon doing the same things that caused the imbalance once, it is likely to eventually happen again.
Since retiring, we have standing monthly appointments with our acupuncturist and acupressurist for sessions. We feel it's a good investment in our health, but we are lucky to be able to afford it.
