很多人会留意到自己的医疗保险是cover acupuncture的，Aetna在自家的Clinical
Policy Bulletin上根据各项研究有比较综合的评价： http://www.aetna.com/cpb/medical/data/100_199/0135.html
粗略看了一下，结论大概是“针扎”对偏头痛和背痛有些疗效，除此以外对绝大部分病
症都没
证据去支持它的效力。
这篇对针灸疗效的评述比较客观，也很值得一看： http://www.quackwatch.com/01QuackeryRelatedTopics/acu.html
摘录它的最后结论：
TCM theory and practice are not based upon the body of knowledge related to
health, disease, and health care that has been widely accepted by the
scientific community. TCM practitioners disagree among themselves about how
to diagnose patients and which treatments should go with which diagnoses.
Even if they could agree, the TCM theories are so nebulous that no amount of
scientific study will enable TCM to offer rational care.
注意，上面给出的两个连接，人家都是有理有据，踏踏实实根据大量研究报告而下结论
的。
