:::I'm not talking about extraction above. Although, since you mention it, the source says that the traditional method for this herb is at room-temperature, an exception to the usual method of boiling.  The scientist recognized this exception, and decided colder was better.  So, the scientist modified the method  who gives a shit whether toward or away from the traditional method, except those who want to push the POV that the traditional method rules/sux?  That's why I removed it altogether ; it's peripheral, and a dumb micro-edit-war magnet.  Sheesh!  Your version is even more of a POV-push than the "inspired" wording; at least that version (before https://en.wikipedia.org/w/index.php?title=Traditional_Chinese_medicine&diff;=588759238&oldid;=588758564 your edit] accurately stated that the traditional method was cold (or room-termperature, which pre-refrigeration meant "cold"). 

 :::As far as the "heat-clearing" business, the both the source about drug isolation and the source addding the "heat-clearing" definition say it's a traditional Chinese herb.  So, per my e.g., two sources agree Mars is a planet; the second adds it's fourth from the Sun.  Mentioning both facts, without making a new inference, is not OR/SYN.  I'd guess that  didn't realize both sources said the plant in question is a TCM herb, hence his concern about SYN.  Move on already!
