I have been lurking around here for quite some time, but never attempted to create an account (too lazy perhaps). I have a question about moxa acupuncture; Can I use a copper handle needle for moxibustion needling, or does the spring steel type, such as Seirin, DBC do a better job conducting heat? I currently use the Hwa-To brand copper spiral handle for moxa needling and some say it doesnt conduct heat as well as compared to when I use the Seirin brand. Others find it the same. What do you guys think?
