Ok i grant it that there have been many important discoveries taken from different animal species which western medicine has derived treatments from, but they have to undergo the rigor of phased clinical trials to prove they actually work. Secondly they dont mass kill animlas purely for the purpose of these so called remedies.

Yeah, that is true. And rhino horns, tiger fangs etc. has obviously been tested for the medical properties, and found to not have any. I think it is very nice to get ideas and inspiration from eastern medicine, but if they are proven to not work, or even be harmful, then we need to accept this fact.
