Trials of traditional Chinese medicine (TCM) are out there (no pun intended), but they're usually not very large or well controlled.
Offhand I can think of a few good reasons why there aren't more such studies, money being the biggest. Controlled trials are very expensive and someone has to fund them. For Western medicine, funding usually comes from pharmaceutical companies or manufacturers of diagnostic devices. As far as I'm aware, most products used in TCM are not patented (I could be wrong) and are produced by numerous companies, so there's far less money to be made by funding research. If your expensive clinical trial proves that bark of dungberry root cures the common cold, there's nothing to stop dozens of other companies from producing it and even using your research for advertising. True, governments provide funding for research, but not nearly as much as the private sector.
Organization also contributes. In the US, for example, most trials are conducted through large hospitals or health care networks, simplifying logistics. In Taiwan, at least, TC seems to be much more decentralized.
