Guest guest Posted November 7, 2001 Report Share Posted November 7, 2001 Todd- What kind of shelf life do you find with the dried extracts? I sincerely doubt that the aromatic herbs have much shelf life in either bulk or granulated form- at least I notice no strong aromas after a few months. I've always been taught that freeze dried extracts had shorter shelf-lives than dried powders because of surface area (although freeze-dried extracts might retain volatiles better initially) and both had considerably less shelf life than properly stored bulk herbs. I see nothing in the extraction method for Chinese granules that would give longer shelf-lives than for western freeze-dried herbs. Yet I find practicioners who insist that they last indefinitely. (That may be a side effect of laying out $5000 for a basic granule pharmacy). I generally assume 3 months shelf-life for an aromatic leaf (bulk) to a couple years for a non-aromatic root or bark. Vacuum packaging will extend these times. Some herbs will still work longer but require higher doses when aged- others deteriorate too much. Tinctures can deteriorate, contrary to popular opinion, depending upon the herb, but probably hold their value longer than any other form and many may as well be indefinite. The invigorating effects of alcohol however may not be desirable and it doesn't actually evaporate with dilution in warm water (once mixed with water, the water and alcohol evaporate at about the same rate.) Unlike Weil, I prefer to purchase my herbs fresh so I can smell, see and feel them. Vitality is far harder to assess with any type of powder. (Of course, mail order puts one at a distinct disadvantage, but you can only mail-order herbs with long shelf-lives and grow or buy others in person until you are sure of suppliers and learn their import schedules for various herbs.)

A virtue of tinctures no doubt, but unless they are 1:1, they are too weak and too expensive for typical use. If they are 1:1, then I think the relatively low dose of alcohol outweighs the energetics of the alcohol. Traditional chinese use of alcohol called for consumption of an entire glass of rice wine elixirs. I do not think a few droppers of alcohol has much medicinal effect from the acohol itself. I used to feel different, but have changed my mind from experience and careful consideration. > > Unlike Weil, I prefer to purchase my herbs fresh so I can smell, see and > feel them. Vitality is far harder to assess with any type of powder. No doubt, but this requires a skill for assessment that I feel few laypersons and even many professionals do not possess.

Even a fresh granular's taste (qi) does not come close to Bulk teas. > > (That may be a side effect of laying out $5000 for a basic granule > pharmacy). > > I generally assume 3 months shelf-life for an aromatic leaf (bulk) to a > couple years for a non-aromatic root or bark.

I have found by smell and taste that Most herbs last quite a while- up to a year or more. Leafies even 6 months or more. An these 6 month old herbs usually (still) smell stronger then powders. Roots last very long. Although, I do get my herbs from Mayway, vacuum packed, and they are STRONG, from the get-go. Strongest I have seen. Though Todd is right, one can only know active constituents through testing. Since I do not have that ability, I go my smell and taste. I am always unclear when I hear that people had raw pharmacies that went bad? Either they are starting with really bad herbs or they just aren't being used. With minimum use you can keep a good turnover and truly minimize herbs going bad. - > > Tinctures can deteriorate, contrary to popular opinion, depending upon > the herb, but probably hold their value longer than any other form and > many may as well be indefinite.

Also, smell of granules is altered because they are on a carrier base, so this is not a completely accurate gauge, either. I disagree with Jason. I have been practicing for 14 years and find granules much much more reliable in potency than raw. One of the most decisive factors is also the errors made by patients in preparation. Laboratory controlled cooking sidesteps these rampant errors. Anyone else with extensive experience out there to comment? Mark Reese?

I agree that KPC is one of the BEST... but... Also, smell of > granules is altered because they are on a carrier base, so this is not > a completely accurate gauge, either. Taste and smell are important to me. TASTE: Once put in the water, is the base dissolved? When I drink a granular tea it does not seem nearly as strong. And the effect on the body, at least for me, does not compare. There is no way I can say the taste compares. See experiment below. SMELL: I am unsure why the base destroys the smell, I am unsure of the chemistry. But just today I sampled multiple hit medicines, in various bases including beeswax etc...they all had very strong fragrances. I disagree with Jason. I have > been practicing for 14 years and find granules much much more reliable > in potency than raw. **this is what I would like to hear an explanation of. What is meant by much 'much' more reliability in potency? There is no way I can agree that granules are more potent than raw herbs until there is some substantial studies with some proof. Someone with 14 years or 50 years experience really means little to me. Length of practice and experience seems moot, one can find anyone (i.e. 20 years+ experience) that says anything... If one starts with herb A, divides it in 2, makes an extract with 1/2, and decocts the other, how is this herb suddenly transformed into a much 'much' more potent product? If it is there are multiple potential problems that arise: A) It is said that the extracts are tested for active constituents, to guarantee potency. IS this what is meant? Problems with this: 1) If one is gearing the extraction process for this marker then one runs the risk of not extracting equally all the components, and moving more and more towards pharmaceutical based thinking. 2) This guaranteed potency and therefore a much different processing that originally intended, for a given formula, would make sense that it is changing the overall properties of the formula. I can not imagine that herb's constituents are extracted in the same ratio as making a decoction, so therefore this supposed higher potency would not be higher in the same ratios in a normally decocted formula, again changing the properties. This is not bad, just a potential problem we should realize. We are no longer giving that same classical formula/ preperation. I even believe individual herbs singly extracted in this manner are going to be different than the originally intended functions, because some of the constituents will be less and some more. This I believe is common knowledge, correct. Everyone knows that different extraction methods yield different components in different herbs. Therefore some methods will make an otherwise useful herb useless (in a given situation). So there testing for the active (main) constituent, to me does not guarantee anything. It just guarantees something that we might not expect. c) Quality of the original herb is moot, because they are coming from the same source. If someone is buying inferior bulk herbs from a i.e. local Chinese herb store then this is a different story. If one is letting herbs sit around until they go bad, and do not have the common sense or knowledge not to use it- that is also a different issue. Maybe 10 or 14 years ago one could not get quality herbs, that is not the case anymore. I have never received raw herbs through MAYWAY that have not be loaded with QI. One could debate that these herbs are inferior to herbs put in the KPC granules.. Well if that is the case buy the BULK from KPC's supplier... Therefore same herb? So... If extracts are much more potent, IS this good? How is this known, besides one's experience, because I hear plenty of Chinese doctors that say the opposite? Do you believe that the formulas act exactly the same as a decoction, therefore just prescribing less to accommodate the extra potency? If they are different, then is it a problem that all our history, and 99% modern research is done with decoctions. TODD: One of the most decisive factors is also the > errors made by patients in preparation. I am unsure about this? Errors? IS a patient only cooking the herbs 5-10 minutes when they should cook for 35? OR an hour and ½?? We all would probably agree actual amount of water does not really matter, it’s a matter of drinking the tea over a given time... IT is not that hard, and really don't see how one could make such a gross error that the herbs would be that much different? Extracting herbs I feel is much more changing (in original preparation methods intended) than possibly minor cooking errors, which is still the intended decoction. I find people do not have problem with the process if it is explained clearly and EASILY- Making it not to complex. Experiment: Take gui zhi tang, make a soup (decoction) see how it feels, get under the covers, see how it feels, even eat the congee if you like. Do the same with a liquid extract, then a granule (different day of course). I have done these types of experiments, that is why I vote RAW.

Guest guest Posted November 8, 2001 Report Share Posted November 8, 2001 Hi,Dr.,Prof.and all, I would like to provide the opinion about the raw herbs , formula powder,granules,the use point in Taiwan an din mainland. A.The most excellent herbal formula is raw herbal formula by decoct method both in Taiwan and Mainland.Some hospitals in Mainland even provide the service for delivery the decocted formula to home. We all know this information in Taiwan(as well as mainland ) that if you get really sick very heavelly,you have to cook the raw herbs by yourself.And you will recoverd very fast if the doctor really provide the correct formula according the correct four diagnosis steps of TCM. Why?Because it is Do-we zhang sha Yao.And the raw herbs is under the most strong situation.Herbal formula is partial of our daily life.The phamacy store's herbs got good circulartion. The raw herbs is not eazy too keep resh,therfore,Every herb stroe 's boss all got their own speciall skill to keep their raw herbs fresh.If you like to learn the skill,be the totur of the boss,he will teach you. Almost every old fasion TCM herbs store in Taiwan all know how to keep and do concoct of herbs very well. Mainland China controll the TCM herbs by government(communism),therefore,I think(becasue I didn't go to deep to their life),in some corners might also reserve these skill,but most of them didn't have their own herbs store in private person,therefore maybe they are not exist any more. For the best quality of the RAW herbs.TCM doctor should learn how to choose the good quality and real herbs. And,concoct the raw herbs by yourself is it is necessary for cure patients. Good quality herbs need to consider these condition: 1. real herb, not forged or use wrong one to substitute. 2.herbs pick up in right seasons. 3.herb growing up in excellent condition,good quality. 4. good product place,for example Si-yang-Sen is from Wesconsin. The shelf time needs to consider the character of the herbs,for some herbs,as long time as best,for example, rice for treat spleen need to us the old years one(some delicious rice cake need last year rice to cook,fresh rice can't create the delicious taste.) and some others.The Concoctology also an great knowledge in TCM. Use correct herbs(raw herbs,concoct herbs,mineral herbs,frankincense,myrrh....)decoct in correct time, correct fire(from strong fire to soft fire), use correct water CC. The raw herbs is the tradiciton effective formula. B.Powders and pills: Taiwan also product excellent TCM formula powders and pill,they all fit the GMP. ,But ,as my understanding of the effect(I taste them before,Gia-wei-Shio-Yo San and Leo-wei-di-hung-won. for a not short period.I was over stressed in my job. These two formula develop in two ways,one is from the decoct formula turn into powder ,the othe is made by raw herbs by follow the TCM " won " product procedures. The second(won) is best then first.(powder and pill) As my understanding,herbs powder only got 60-70-80% effective according the quality of the product.because, 1.the quality of the raw herbs the phamacy factory used.if they chose high quality herbs,the effect is excellent.if they chose the low quality herbs,you can image the results. 2.during procedure,some chemistry changed not like the tradition decoct way because the " fire " degree(charcoal provide steady fire temperature and pottery can make great one) and some herbs need cooked first and some need cooked after.Maybe the phamacy factory didn't or can't follow the whole old fashion procedures so far. 3.the procedure to turn decoct juice into powder need to add some satrch and the satrch might weak or dilute the effect of the juice. C.granules We didn't use this type of TCM herbs .thry are rare in Taiwan.But,In mainland,it is popular I guess.We can buy it in Taiwan in some stores.I drink it once before.It seems that granules defined their position in soft drink for a very light dosage in herbs. These are my opinions. Sen-long Shi taste herbs.Every TCM doctor in Taiwan all taste herbs by themselfs.More or less,we need some real experiences.Then,you will know when your patient drink it,it really need great courage in Western.Ha! \(^-^)/!

Guest guest Posted November 9, 2001 Report Share Posted November 9, 2001 Dr., >One thing that always has puzzled me in the states (and possibly in China ; Taiwan) are that the herbs are kept in those wooden drawers, No,they didn't.there are small among herbs in those wooden drawers,running out,add more in fresh.They keep the others in a dry,air ciraulte weel places.Some herbs wraped in thick paper to keep in a dry condition. some are smoky dry by some nature chemistry staff,humless to the herbs(for prevent the herb worm). constantly exposed to air...?? It is not exposed to air,it is exposed to sun light. sun light dry can killing bacterias(isn't it morden way?Yes!! Ha!)and keep the herbs in a very dry condition. We all have same feeling the rice from sun light dry is more delicius then rice from mechine dry.Sun light dry also can make some micro change to the herbs or rice which we wtill unknow from scientific evidences until now. Taiwan is on a wet weather conditions than mainland and US.Therefore,in ancient time,sun light dry is very important for the herb stores. Now,I think the herb stroes use machine(dehumidifier) or refrigerator to help preseve herbs. > This is one reason I think herb stores usually do not have fresh herbs... No,In taiwan,their herbs have to be fresh very much.some customers are expert,too.If stores sale bad herbs,the customer will gone. Yes it is fast, but jars seem to make much more sense? Opinions ? if jars means big glass bottles,the answer is the wooden drawer and thick paper also can dry the wet,pervent the wet.Glass bottle will keep the moisture in the bottle. the herbs quality will turn bad very soon. Glass bottles only preserve mineral or herbs wine. We also make herb wine(according herbology plus rice wine) for treatment Qi-kun or boxing punch illness.Or ,for winter and daily drink,3-5 cc a day or more to keep the body energy strong. And, so many other way that hardly can tell. That's why we all say that TCM is wisdom of ancient. Wide like ocean.

Guest guest Posted November 11, 2001 Report Share Posted November 11, 2001 I think herb storage works differently in different conditions. I find jars in a dark closet to be the best where I live. I do think that air circulation will hurt aromatic herbs. And jars contain the insects reasonably, if you check so you get them before the larvae crawl out along the jar threads. (Hanging strips of fly paper in the herb closet helps with meal moths too.) However when Rosita Arvigo moved to Belize where the air is very humid, she had lots of trouble keeping her herbs in jars from molding. A local curandero suggested that she use brown paper bags and her herbs stopped getting moldy. Of course the climate is less variable there so she can get fresh herbs frequently rather than one season a year as most of us must do. If they lose potency and she replaces them regularly it is less of a problem. Perhaps conditions in Taiwan are more like those in Beliz.

Guest guest Posted November 11, 2001 Report Share Posted November 11, 2001 Hi,Karen, Yes,Weather in Taiwan is wet then US and north part of mainland. We usually use Yang-zi Chung to separate north part of china and south part of main land.Taiwan is an island and locate in very lower south corner of China,surrond by sea,therefore, we get wet air almost 4 seasons. But,mainland also use wooden drawer and paper to pack herbs in the herb stores.

Guest guest Posted November 11, 2001 Report Share Posted November 11, 2001 Hi,Karen, let us think this way, When you buy vagetables, and you keep it in the plastic bag,what will happened? The fresh vagetabls need to breath and water circulation if it is still fresh. The herbs after machine dry maybe still remain some water and it still breath and circular in a very mild situation(as well as after amputation,some patient still feel leg pain,in Qi theory,maybe invisible Qi still circulate after amputaion). Wood drawer and paper provide fiber spece for air to circulate which jars and plastic bag can't,therefore,herbs can preseve in good condition and the herbs still alive. If the herb still alive,they will need good air circulate when you preserve herbs.That 's what karen saw.

If one is present, then so are the others that come out with water and in proportion. But if there is no ephedrine in ma huang, there is probably little else as well, for example. this has been demonstrated in europe with standardized extracts. > > 2) This guaranteed potency and therefore a much different processing that originally intended, for a given formula, would make sense that it is changing the overall properties of the formula.

Did they really follow the TCM theory or TCM concoct procedure before decoctions?If the answer is " yes " , Did researcher provide the procedures he/she concocted?if it is " no " ,How many % of 99% is correct ?Wrong begining develop wroung result. >the powders are made form decoctions and most of the research on decoctions is probably bogus> Why come out this conclusion?You believe the efectiveness of powder from decoction but claim the decoction researches are bogus? In Taiwan,We have many GMP(some technics are from Japan decades ago.,some are traditional TCM techs.) factory of powder.Shu-Tan-Do,Sen-chun,minton..... We have at least two type products: A.concoct then add starch dry(like milk powder). We assumed the resoures of herbs all qualify becasue the datas they provide are correct because they are GMP standard.We don't have to request the scientific finding.And our product is excellent because I used it for two year. In the mean time,I visited Peigin and bought same formyla Lio-we-di-houng-won and Gia-wei-shao-yao-san from Tong-ren-tone,Peigin.Their effect were much much weaker than our products(Taiwan).I think the raw materials are the key issue. Most excellent quality herbs in mainland are sold over sea for eran more and more money during that period. The commond problem that A type factory still can't claim their powder is 100% like concoct formula because 1.they have to add starch for turn into powder, 2.they can't follow all the procedures tradition concoction method and decoctology. 3.the procedure the dry might cause some ingrident running away from air,for example, peppermint... As well as Mainland and Japan,Japan have many kanpo products. I have been visit ?(123)biggest factory in mainland once.Also ,I saw many produts in Tokyo and Osaka. And according my two years experience of using these product,their effects were slowly.If patients problem is not very heavy,(sickness level 10-40%),it might bring patient back to the normal stage. But,If patient's condition is tough,the effectiveness of powder will turn useless or need longer peirod.And ,when the powder used reaching some level of disease develop ,the patient's situation will get no progress by useing powder because powder Yao-qi can't push the illness Qi.. B Type: use raw herbs and tradition sikll to make product. sen-chun has a good product:Lio-wei-di-houng-won. I also take this product for two year. " won " meaning slowly,and completely, it goes very slowly and will get will completely.Therefore ,long term diseases need " won " to take care of. It smash(milled) raw herbs(sun dry is better than machine dry)add cooked honey and turn it into " won " by machin. I have to say,sometimes,this product can't compared with hand made Lio-wei-di-houng-won by some experienced herbs stores.(I bought others before,cirous girl,Ha!) The experienced herbs stores's boss known how to chose excellent quality herbs becasue The buyer ordered it and willing to pay higher price for hand made Lio-wei-di-houng-won. For common use, B type product is much excellent than powder. If doctor in US can get good quality herbs and patient will to do concoct,I don't think there is any thing wroung and the experimental concoctions are not bogus.We use them and drink them since we are childhood. If patient don't have time to do so,for common use, powder , " won " product , " jao " product is another good choice. Ok,I know the good and bad of those stuffs,do you believe that I know how to invent new methods? Ha!
