Guest guest Posted October 8, 2003 Report Share Posted October 8, 2003 Ye Hu Da, The effectiveness of qinghao will be diminished if it comes into contact with iron. Hence the use of an iron pot for decoction, or simultaneous iron rich food is contraindicated. This is true at least when qinghao is used as a 'simple' for treatment of malaria. There may be more subtle levels at which qinghao works where contact with iron enhances not diminishes a desired property. That is just my limited knowledge as a student of TCM, not an expert by any means.

Guest guest Posted October 8, 2003 Report Share Posted October 8, 2003 Hi again Sammy, I just checked Bensky and Yeung, and nothing is mentioned about iron antedoting or diminishing the effectiveness of qinghao. What's the source? Thanks, Yehuda On Wed, 8 Oct 2003 12:32:11 +0100 <ga.bates writes: > > Ye Hu Da, > > The effectiveness of qinghao will be diminished if it comes into > contact > with iron.

Guest guest Posted October 9, 2003 Report Share Posted October 9, 2003 There must problems with all sorts of containers. High lead content glass or ceramic glazes made with chromium have been known to cause poisoning. Is not that sort of thing covered in TCM courses' toxicology modules ? Sammy.

Guest guest Posted October 9, 2003 Report Share Posted October 9, 2003 Of course, but these are concerns with those who live in 3rd world countries (like China, dare I say!) with substandard regulation of toxic metals. But here in the good old USA, and other developed countries, why would it be anything less than preferable to decoct herbs in stainless steel, iron or pyrex pots? I'm still waiting to hear from anyone as to what the source is as to why qing hao can't be decocted in metal.

Guest guest Posted October 9, 2003 Report Share Posted October 9, 2003 I just know that when I first started taking raw herbs I thought the metal pot thing was silly but after 2 months of metal pots I switched to a stone pot. I noticed the difference in the potency of the herbs immediately. doug But here in the good old USA, and other developed countries, why > would it be anything less than preferable to decoct herbs in stainless > steel, iron or pyrex pots?

Guest guest Posted October 10, 2003 Report Share Posted October 10, 2003 Yehuda, If you do a Google search with combinations of the following terms ' qinghao artemesia iron ' as the search phrase I am sure something will turn up. You could also try PubMed as this is one of the few TCM herbs that have received a fair bit of attention by commercial interests. I believe the Chinese have most of the patents out on the artemisenins (the family of derivatives from artemisia) which is probably why we haven't heard an awful lot about the modern development of qinghao in the West unless you go to the technical literature. If your own search fails to turn up anything, let me know and I will dig out something from my archive. BTW: Please don't think I am ignoring anyone but I am having difficulty following threads on this list because the ChineseHerbalAcademy subject header blots out the rest of the line on my email reader. Couldn't it be changed to something more succint e.g. CHA - as Attilio did with TraditionalChineseMedicine --> TCM Sammy. yehuda l frischman [] 09 October 2003 23:11 Re: metal pots Of course, but these are concerns with those who live in 3rd world countries (like China, dare I say!) with substandard regulation of toxic metals.

Guest guest Posted October 10, 2003 Report Share Posted October 10, 2003 I think that enamel coated iron pots would be about the same as the clay pots in Chinatown. I gave up on the herb pots since I'm too impatient and they always crack. I think the warnings of metal pots probably came from the old days when they used uncoated iron / steel and you would get a reaction between the herbs and pots, like you do with cast iron and tomatoes. I'm not sure if stainless steel is more inert and therefore acceptible for herb cooking. I know that some people here use crock pots too, which are cheap and easy, but not too fast. 'you can have it good, fast or cheap, pick two!'

The supervising doctor (Dong) was not too happy about it. doug Quote Link to comment Share on other sites More sharing options...
