Well, there ARE tcm things that work from time to time, but this occurred out of a 'trial and error' practice over thousands of years. In the mean time, more people have died from being poisoned and god knows what else as 'doctors' feed people random deadly plants and herbs until one happens to work. Then we forget about all those who died in the process and hand out a random mystical explanation as to why the one that worked, worked.

Meanwhile real scientists isolated the molecule in the plant, found that it can be found in all these other things, replicated it, checked it for other safety and side effect issues, wrote a publication about it, had it peer reviewed and its studies replicated and approved and send out to the pharmacies.
