I hear what you are saying. the lecturer in question was somewhere in between the academic world while they did practice and actually showed us how to needle. Perhaps more on the academic side.
regarding the old wives tales and cupping/scraping i have met many muslims, greeks, and north african s who use this practices for the common cold. I do believe it draws out heat and wind. In arabic it is called hejama. GOod old grandmothers also have some recipes for broken bones i wanna track down. I spoke to a uni friend the other day that told me she gua shad her lung channel to nip a wind cold heat in the butt. she did later get a stomach bug though. Oh well
Regardning the needling though we have points such as Li 4 or lung points,yintang , ear lung, and while I have found they can give releif I am looking for something similar to the instant releif that i have seen in food poisoning, musculoskeletal issues, and headaches which I have been able to get instantaneous results with. i know this sounds a bit rigid and narrow focused. I suppose i am trying to build my faith so i can apply it to my intent> your simple words that remind me that it works and works well, helps bolster the faith that cops a battering from those outside and more pertinently those within our area of knowledge.
Thanks for your response(again)
