I see alot of people believe that look is what determines the roots origins, especialy when they want to sell it. No buyer comments though,interesting.So for those whom I speak, I would like to sell you some gold, some real some not so real but all at the same price, right, it looks the same....
In the past it was to difficult to find out the truth how a specific batch was grown,or it's origin because of the lure of the all mighty buck.In other words our inherent need to lie or mislead for ones own gain, we all have it, that little voice that says, this guy don't know, or this guy can't see it.All for a few extra bucks. ALL IS GOOD AS LONG AS THEY DON'T KNOW THE TRUTH, but now the truth is easy to find.Origin of seed and how it was grown, all from a simple test. Here's something funny, this test was developed to protect us from the unscrupulous in the herbal medicine trade.Go figure!?!
Ginseng is one of the most expensive Chinese herbal medicines and the effectiveness of ginseng depends strongly on its botanical sources and the use of different parts of the plants. In this study, a microchip electrophoresis method coupled with the polymerase chain reaction (PCR)?short tandem repeats (STR) technique was developed for rapid authentication of ginseng species. A low viscosity hydroxypropyl methylcellulose (HPMC) solution was used as the sieving matrix for separation of the amplified STR fragments. The allele sizing of the amplified PCR products could be detected within 240 s or less. Good reproducibility and accuracy of the fragment size were obtained with the relative standard deviation for the allele sizes less than 1.0% (n=11). At two microsatellite locations, American ginseng had a different allele pattern on the electropherograms compared with that of the Oriental ginseng. Moreover, cultivated and wild American ginseng can be distinguished on the basis of allele sizing. This work establishes the feasibility of fast genetic authentication of ginseng species by use of microchip electrophoresis.
Alleles, in layman terms are compareable to your cousins the more you have the more like field grown you are, the more diverse you are. The ability to breed and get more cousins is increased in an over crowded enviroment. But by that stream up on that secluded mountain the three hundred ginseng plants that have been there for hundreds of years will all be direct family members with no cousins. Little diversity, except to the conditions they grow in.
For those who think the truth is in the buyers eyes.
Great topic...
