如果只是看部分解释, 而不看全文, 还真被懵过去.
关于中医, 从美国食品药品管理局（ＦＤＡ）指导性文件文中可以看到:
1. CAM与常规医学有显著的差异. 中医是CAM的一种.
2. CAM现在有四个分类. 以前有个第五类. 由于第五类包括前四个分类, 所以第五类归纳为"whole medical systems".

再看看"whole medical systems"的定义:
(http://nccam.nih.gov/health/backgrounds/wholemed.pdf)
3. whole medical systems包括: Major Eastern whole medical systems include traditional Chinese medicine (TCM, 中医) and Ayurvedic medicine, one of India’s traditional systems of medicine (印度草医). Major Western whole medical systems include homeopathy and naturopathy. Other systems have been developed by Native American, African , Middle Eastern, Tibetan(藏医), and Central and South American cultures.

4. 看看对whole medical systems的总结:
.... To date, NCCAM’s research efforts have focused on individual therapies with adequate experimental rationale and not on xxxxuating whole systems of medicine as they are commonly practiced.
美国人只是对一些特殊的疗法感兴趣, 对whole medical systems根本没有评估. 如果没有评估, 如何得出"科学"的结论. 即使评估, 也不一定能得出"科学"的结论.

最后本人只是不明白, 自己的中医为什么要让别人承认才"理直气壮". 并且还牵强附会, 不惜断章取义, 以达到目的.
美国人把中医分类到CAM, 同印度草医,藏医, 以及非洲的"巫"医等相提并论, 一些
人还大张旗鼓的宣传. 不知道这些人是贬低中医还是赞扬中医?
