Guest guest Posted January 22, 2009 Report Share Posted January 22, 2009 Eric, Maybe your comment was in passing and trivial. I figured if I thought it was interesting enough to think about and comment on then others probably did also. Sorry if you feel it should not be 'dissected'. I personally do not think anything is 'trivial' otherwise why would you say it? But I think, right or wrong, the concept that granulars are more potent than bulk (even if 1 herb) warrants investigation via critical thinking. Without evaluating such statements properly we can all of a sudden have people saying, " I heard from source XYZ that granulars are stronger and more effective than bulk. " I think it was you who asked where does all the misinformation come from? It is from people not being clear with their thoughts and sources, as well as people just riffing (not that you doing any of that). However, everything, especially in writing, needs to be critically evaluated, and made as clear as possible. If you feel my concerns and criticism are too harsh then next time please feel free to site were the citation comes from, let us evaluate the research, and bow out. I think everything we say and think should be challenged, period. For example, if someone says treatment X is effective, I will always ask where is this information from / how do we know this? An answer may come from many realms, from personal experience, or from 'heard it from a friend' to a double blind study. Qualifying information is essential for progression of medicine. After knowing the source we can ask questions to help further evaluate how true a statement might be. We all know that medicine is fraught with misinformation and poorly presented 'statistics'. I personally am skeptical about most things I hear. IMO, it is our JOB to think critically and the first step it to try to explain things that seem contrary to normal experience. This pu gong ying might be no big deal, but the basic methodology you present for determining potency compared to raw herbs is just IMHO flawed. I do not need a biochemical degree to ask the questions and come up with possible explanations for interpretation of the 'data.' I also have no qualms about admitting I am wrong about such an issue when there is overwhelming evidence to the contrary. Finally, I feel like I have brought up very valid concerns about the granulars (in relation to extraction ratios) and as often happens the original question never gets addressed and somehow the conversation gets deviated into long drawn out red herring emails. Actually 'my' concerns and criticism are not from me at all, but leaders in the field, with much more experience than most of us on the list. Therefore I feel they are very worth discussing. Maybe people feel that none of this should be debated, but I have personally enjoyed the responses from others and look forward to further comments. But I can tell Eric is done with this thread for the moment, so I will wait until it comes up at a later date. CHA does have many lurkers, as does every group. But this may be partly because of people asking questions such as where is it from? Our field has a strong reputation of MSU and one thing I value about the CHA is our group's ability to ask questions and think critically and not swallow everything hook line and sinker. This may not be for everyone, but after spending time on some of the many other Chinese medicine groups this element of critical questioning and thinking is greatly appreciated. IMO, this really keeps the reins on some very out their stuff. For better or worse, right? I know it has been a criticism of others on this group before. I welcome Doug (the moderator) to contact me if he feels my way of thinking is out of line.

Guest guest Posted January 22, 2009 Report Share Posted January 22, 2009 hmmmm... well, CHA has had the pleasure of this impressive exchange between two really impressive figures. Eric and Jason, you both constantly amaze me with the depth of your knowledge and passion towards each subject you take on. There is no need to apologize... in my view, the granule question will remain a question as long as we have the privilege of using raw herbs to compare them to. I just throw up my hands when faced with trying to explain how to dose granules. (I use what is on the box so to speak) I see the issues (and I've kind of forgotten what they are) as pretty unresolvable. Therefore I especially admire and tip my hat for the attempt to unravel the connection between what has been in the books for a few thousand years and the technological developments of the last 50 years. At some point, (if not now or perhaps it has already happened), granules will be their own " standard " .

Guest guest Posted January 23, 2009 Report Share Posted January 23, 2009 This is a very good discussion and I learned a lot from you guys. I'm not sure if everyone is aware of the debates about the dosage of raw herbs. Basically the dosage that used in Shang Han Lun is about 5-10 times stronger (raw herbs to raw herbs) then today's textbook. Each side has their supporters, but most people will agree that the correct composition ratio of herbs in a formula is much more important then the exact dosage of each individual herbs. This is especially true for the formulas in Shang Han Lun because there each formula has its special ratio. If you prescribe a formula using the ratio of 1:1:1:1.. for all different herbs, then I guess the dosage become more important here. This is why most Taiwanese doctors I know do not pay too much attention to concentration ratios (once they choose a brand), but they will avoid mixing granules from different brand into one formula. If they don't get a good result from it, either double/triple the dosage in the formula, or re-exam the patient and change the formula.

Guest guest Posted January 26, 2009 Report Share Posted January 26, 2009 Bill, This is not necessary true, there are many factors that determine the ratio of constituents, and this is the whole debate.

With the > powdered extract, the drying is just an additional step. The interesting thing is, it is only really because of the granule industry and its water-based extracts that we know what we know about the chemistry of decoctions in the first place. The main area where the decoction process is mimicked with lab analysis is in the research department of granule companies. China has an official pharmacopoeia that contains detailed information about thousands of substances, their national pharmacopoeia is in fact a mixture of herbal, animal, and mineral crude drugs (Chinese traditional medicinal substances) and modern pharmaceuticals. It is a 3 volume set published by People's Medical Publishing House (PMPH), priced for academic institutions at something like $800. It has information on the chemistry, extraction procedures, drug analysis and use, TLC and HPLC assessment, microscopic assessment, etc. It is the definitive work on the topic and contains the core material that is used by all the lab companies that do testing analysis on Chinese medicinals as well as by all the pharmaceutical companies that make granules in both mainland China and Taiwan. Where does this data all come from? Apparently a significant portion of the TLC (thin layer chromatography) analytical standards that are used for identification purposes in the Chinese pharmacopoeia were actually done by China's largest granule company. Really the main labs for decocting authenticated Chinese medicinals for analysis are either the granule labs themselves or academic institutions such as that of Hong Kong Baptist University. I suspect that the situation in the US is not much different, much of the scientific information that is published on pharmaceutical chemistry comes from either labs in academic institutions or the pharmaceutical companies themselves. When I really heard that the TLC ID standards used by the government actually came from a granule company, I was both surprised and not surprised. For better or worse, the distance between the state and private industry is not always very wide anywhere in the world, US and China alike. All the world uses the Chinese pharmacopoeia as the base standard for all things related to Chinese medicine. Fundamentally China's largest granule companies have a lot of government connections and SATCM (State Administration of TCM) support, so I wasn't really surprised when I heard that they contributed to the TLC section of the national standard. In yet another illustration of how hard it sometimes is to separate science, government, and the private sector, I recently saw two whole books on the subject of granule research (comparing granules to raw). One book was published by the publishing branch of China's SATCM (State Administration of TCM), but nearly all the studies used granules from a single supplier. However, nearly all of the hospitals in the country using granules (I heard over 1000 hospitals now) use the same granules from said company. Just as our field here is a close community at the top of the field, so is the Chinese community of Chinese medicine in China. The people that run the big hospitals, big publishing companies, and big pharmaceutical companies all know each other, they have worked together earlier in their careers, they see each other at conferences, they all occupy the same network. Obviously there is inherent bias present, but essentially the situation is probably exactly the same with the pharmaceutical, university, and trade organizations for WM here in America. Its just how it is, we know about the constituents of herbs/actions of drugs because labs analyze them. Some labs are private and some use public funds, and all can be biased or ethical and fair. Interestingly, these two books have hundreds of summaries on clinical research comparing raw herbs and granules. Because mainland Chinese hospitals mix granule formulas from singles instead of boiling the formulas together, this research also compares the differences between cooking the herbs together in a home decoction vs. mixing singles. At a glance, some of the studies have better designs than others and I'm sure that selection bias may exist, but clearly a lot of people have looked at the issue. I am personally a strong proponent of cooking the herbs together. Thus I prefer to use the Taiwanese prescribing style of starting from base formulas that have been cooked together. I'll be in Taiwan in a few weeks so I will try to find some more research that looks into it from this angle. (I believe that the awesome Jiao Shu-De Ten Lectures on Formulas book by Paradigm contains an interesting reference to this concept in the bu zhong yi qi tang monograph, if memory serves.) Yet despite the fact that I prefer using whole formulas that have been cooked together, I cannot let my own bias prevent me from noticing one simple fact: hundreds of thousands of patient visits in China are managed by granule powders (most above 5:1, incidentally). Clearly there is therapeutic value. Chinese doctors are often conservative to change by nature, and the doctors there have a lot of experience using raw herbs. If the granules weren't working reasonably well, people would notice. Of course many doctors in mainland China and Taiwan eschew granules, but a significant number of doctors are generally resistant to any changes (some doctors even still rely almost exclusively on classical formulas, for example). Nearly all doctors prefer raw herbs but most concede that granules have their place. I would say the general consensus is that they work, there is a huge body of evidence that supports granule efficacy in both mainland China and Taiwan, despite their different respective approaches. As an aside, it should be noted that many companies that produce extracts in China for the US or other export markets do boil the herbs together in a traditional decoction (for example, Blue Poppy, Nuherbs, and Nong's all do this). This is something of a fusion between the Taiwanese approach and the Chinese technology. However, these compound formulas are rarely available in mainland hospitals. For people who want to read some of the studies (Chinese only), the two books I found are called " clinical use of granulated Chinese medicinals for formulations " zhongyao peifang keli, linchuang yingyong by the SATCM press (zhongguo zhongyiyao chubanshe) and " use and research of concentrated Chinese medicinal granules " zhongyao nongsuo keli de linchuang yingyong yu yanjiu by PMPH (renmin weisheng chubanshe). (btw, I haven't come across the pu gong ying research citation in there yet, but it was done by the Shandong University Hospital in Jinan, China, don't have a way to check it b/c I'm on the road.)

Guest guest Posted January 26, 2009 Report Share Posted January 26, 2009 Another area to consider is what is lost in the dehydrating process. Perhaps there are some constituents that are sensitive to this process and don't make it to the final granulated product. Some herbs like Da Huang are only traditionally cooked for a couple minutes and I have heard that when dehydrated there is nothing left because the original brew was too watery. In this situation granule companies will mix in some of the raw ground herb as a filler. Even though I have seen that granulations of Da Huang work very well in promoting a bowel movement, I wonder about other effects that are perhaps lost. For example, Jiu Da Huang can be a good herb to bring heat down away from the face when treating acne, particularly when the face is flushed. When using the granulation of this particular herb, I have questioned its effectiveness as the results have not always been great. I really haven't used it that often yet so I don't have the greatest opinion, but nevertheless it is still a question that I seek to answer. And then, on the other hand, I remember being told that aromatic herbs lose a lot of their punch when made into granules because of the delicacy of the oils within them. But I have to say that I had enormous success in treating many cases of Allergic Rhinnitis this last spring, 2008, using granular modifications of Cang Er Zi Tang, a formula rich in aromatic oils. So obviously many of the so called sensitive herbs still managed to keep their potency through the granule making process.

Guest guest Posted January 26, 2009 Report Share Posted January 26, 2009 In term so of singles versus compounded formulas, this has always been a issue for me that I have not been able to resolve. On the one hand it is easy to understand that new chemical compounds will be created when herbs are cooked together and that these compounds will have an effect on the treatment. So on this level, I agree that using whole formulas with granules make sense. But then I have watched one of my mentors, who is Taiwanese, make his own traditional honey pills using fresh ground powders mixed together. These herbs are not cooked together, they are only mixed together, and the end results for the patients taking them was usually very positive. In my own personal clinical experience with granules, I have found greater results when I can make my own formulas from singles, especially when treating atopic eczema or psoriasis. This could be due to dosing, as when I use the singles the patient is usually getting a much higher dose of granule than when I use the scooping of pre-made formula method. It could also be related to how I am combining multiple formulas and singles together, and that I need more time to perfect this. I would love to sit in on some Docs in Taiwan who use granules, particularly for dermatologic problems, and see how they (the herbs and the Doctor himself) work.

If water is used as a solvent in making an extract, it should have a similar profile to a decoction, which is also a water extract. Things get strange when other solvents are used, especially when the whole thing is run through a column to concentrate certain compounds.

Guest guest Posted February 1, 2009 Report Share Posted February 1, 2009 Jason, If you have seen these articles, could you provide links? Making a blanket statement that aqueous dried extracts are different from decoctions needs some evidence to back it up. Simply stating that you have " seen articles " or that " Andy says so " does not constitute evidence. This is an important issue that requires scientific evidence, since it is a science issue that is being discussed. - Bill , " " wrote: > > Bill, > > > > I have seen many comparative studies / articles that discuss the differences > using methods such as HPLC.

Guest guest Posted February 2, 2009 Report Share Posted February 2, 2009 Bill, Sorry you will have to hunt these down yourself, I do not have time, sorry I brought it up. For me, it is just common sense and knowledge that the two (aqueous dried extracts & decoctions) can be vastly different. Most of what I have seen has been in journals (not links) and many in Chinese. I read these years ago. As stated, Andy makes a clear presentation of this idea, and he may have the actual studies more handy. I do not keep this stuff lying around. I am also sure Western herbalism has this info. Check there. BTW- Andy is one of the most experienced and knowledgeable experts in the west on the subject, therefore his word is pretty strong. But as stated in my previous email, don't take his word for it, contact him and get the studies. But contemplate this, the mere fact that different ratios of extraction exist for different herbs, says 1 thing, that ratio matters. If ratio matters (and companies do debate which ones are best) then CLEARY one can make a " aqueous dried extract " that differs from a decoction. Therefore since many companies are doing things drastically differently at this point (different technologies, different ratios, determining proper ratios on different constituents) then is common sense (at least to me), that some of these are going to differ more than others when compared to decoctions. Are you saying that every company out there has a product that is identical to a decoction? Of course this is not true, therefore we can make the statement that just because someone makes a aqueous dried extract that it will not inherently be identical to a decoction. Some may be closer to others. Clinically also this is quite obvious to me. So I have no need to say anything more or hunt down studies. Thanks for the dialogue. -Jason On Behalf Of bill_schoenbart Sunday, February 01, 2009 9:29 PM Re: Granule conentration ratios Jason, If you have seen these articles, could you provide links?

Guest guest Posted February 2, 2009 Report Share Posted February 2, 2009 I would like to review Andy Ellis's essay on granular. Could you please direct myself and the group to its whereabouts. Thanks so much, Jennifer Quote Link to comment Share on other sites More sharing options...

I strongly agree with Bill that scientific issues require investigation and evidence. Jason, you often advocate challenging ideas and assumptions and are generally keen to request that others provide citations and supporting evidence to back up their viewpoint. So it is a bit disappointing that you tell Bill to go dig up the information himself after you say that you've seen multiple supporting articles on the topic. You are correct that Andy Ellis has written a nice essay on this topic, and I would be among the first to point out that Andy is very knowledgeable on the topic of granules. However, as much as I like Andy and respect his expertise, one essay published in the product literature of one commercial granule company is not sufficient evidence for a mature scientific debate. Andy's article can be found in the Notes from Cinnabar Creek published by Golden Flower Chinese Herbs, it is a provocative read. Bob Flaws, another noted expert in the field, has published an article from Blue Poppy that challenges many of the points implied by Andy's article, and is another essential article on this topic. The Evergreen catalog (the product literature of yet another vested interest) displays a HPLC chart that shows that their products are higher in certain constituents than some of their competitors. Remarkably, the product literature of every company tends to suggest that their own products are the best. The advancement of the discussion requires us to move beyond the level of " Andy says, Bob says, John says. " Generally a mature academic debate requires that evidence be presented to challenge the prevailing scientific opinion. Currently, overwhelming evidence supports the fact that full-spectrum water extracts as made by granule companies are chemically similar to (gasp) conventional full-spectrum water extracts. Sure, you can add different excipients and dilute this extract to different degrees, but much of this dilution has to do with business decisions such as delivery style rather than science. Granules in Taiwan are colloquially known as " ke xue zhong yao, " (scientific Chinese medicine)- specifically, the science of producing granules is the effective replication of the traditional water decoction. You test which constituents come out in ideal lab conditions, replicate it on a commercial scale, and test to ensure that the final product conforms. True, different companies use different excipients and achieve different concentration ratios. But we need to move beyond asking the salesmen and start actually looking at the issue scientifically. For this, we need concrete examples and data. It is easy to barrage someone with questions and demand evidence, but it actually requires time and effort to collect information that adds to the group's understanding. If everyone thinks the world is round and I say it is flat, typically I would be the one that would need to produce evidence that shows that the world is indeed flat, since the prevailing scientific evidence of our time suggests that the world is round. At present, there is an overwhelming amount of data to support the herbal science that guides extraction and granulation. If you think that a large group of these companies and scientists have it all wrong, it would be helpful if you could supply perhaps even a single example or two that shows that some of these granule technologies produce products that do not reflect the constituents yielded by a traditional water decoction.

Guest guest Posted February 3, 2009 Report Share Posted February 3, 2009 Eric, It is true that I ask regularly for citations. It is an important step. If someone does not have them, one can qualify the argument anyway they like. However, I will be the first to say that everything is not decided by " research. " For me it is only one piece of the puzzle. If someone though, quotes that XYZ was more successful in 56,000 people then this requires an immediate citation IMHO. Broad concepts that can be parsed through without a specific tests/ research are less likely to be decided by papers and research especially when the companies that market the products are usually responsible for the research. In this case, as disappointing as it may be, I do not have time to try to find these studies, actually I see no need to understand this point. Maybe you do, and we differ on that and why I do not care that much. I have already mentioned a probable place to find specifics, as well as cited a published English article that discussed this issue specifically. I am sure the author can provide citations for his stats e.g. that there are many factors that go into changing the ratio of constituents for end product granulars. So I do not have the excat research, but at least there are opinions that agree with mine by people much smarter than I. But really is there anyone saying otherwise? Therefore, if someone really cares they can pursue the lead I gave. If they just want to say, where's the citation, then sorry, I don't have it. However, the mere fact that companies present data that shows that their product is more 'correct' or 'better' than competitors is important enough to consider. Meaning, there are differences among companies, period. These differences are easy enough to prove with one's tongue and clinical experience! Hence granulars are not guaranteed to be equal to bulk decoctions, just because they are granulars. Otherwise all companies would be equal. But the reality is, some are better than others. This fact proves (IMHO) that as I originally stated, a granular does not guarantee anything and there " are many factors that determine the ratio of constituents. " I asked before and I will ask again, to Bill and Eric (and others). Are you saying that every granular out there has a similar profile as to a water decoction? If this is the case where is the evidence for this? If it is not true, then my point is proven. If some companies are better than others (constituent profiles) then my point is again proven. Otherwise one would be saying that the only variable between companies is extraction ratio, not constituent ratios? If this was actually the case I doubt there would be so much arguing out there. Western herbalism and supplement companies have oodles of support for this concept! There are different techniques that produce different profiles, hence producing drastically differing clinical results. Sorry no citations, this is just from years of exposure and reading. Again the reason I say that I have seen articles is so that if someone really cares they can find these things and evaluate them for themselves. Since I have the utmost respect for people like Eric who really have a passion for this topic, if he (or others) were to say clearly that all the companies out there are producing identical products and they were all almost identical to bulk, and that the only difference is extraction ratios, then I would have to consider the flip side. But to date I have not heard anyone say this, at least anyone with true expertise. Such a stance would counter what I am suggesting. Otherwise what are we debating? But my understanding of the topic (reading articles and convo with experts), my taste, and my clinical experience definitely says there are differences between companies. That is what I stand on. What these differences are I do not know. It is my stance that it is not just one has a higher (or lower) extraction ratios. But the mere fact that there is differences (between granulars) is evidence enough for me that says they all can't be equal to a bulk decoction. Simple logic here. Hence this observation supports my initial statement that there are many factors that go into making a correct ratio that is equal to a decoction. I really do not care enough more about the discussion to produce scientific articles, although I agree that they are needed in general. But I do await Bill's proof to counter my statement, since it was he who actually made the initial statement.
