KP has

done testing of its own products and they reveal that active constituents

do not decrease substantially for up to five years if the bottle remains

unopened. Once a bottle has been opened the shelf life varies with

the

herb. Those herbs with lots of oils can get rancid in a year or so

or even

sooner if the temperature is warm. Most herbs however were found to

retain

potency for at least one year after being opened.

My hunch is that raw herbs are similar but I have no data to back up

that

hunch.

I think that one should not compare the smell of the granules to the

raw

herbs because the granules are (by and large) cooked already. It would

be

more accurate to compare the granules to the decocted liquid but even

that

has problems as obviously liquids are more volatile and thus have a

stronger smell. In addition, the base for some granules is the raw

herb and

for others it is starch. Thus those granules whose base is raw herbs

should

have a stronger smell.

Hope that is useful information,

Best wishes,

Andy

The same would be true for Qualiherb re using HPLC etc for batch analysis after storage.

Also found out that qualiherb atends to the species identification

issue very closely. As someone used to say, " ha! "

I am not sure this is true. Herb ID is not necessarily a GMP issue.

If the case can be made that a safe nontoxic species is actually used

as say, sheng ma or ban xia, in some parts of china, I don't think GMP

applies. these are not really mistakes as much as judgement calls.

there is no doubt that most sheng ma in raw form is NOT cimicifuga and

I suspect this is true for some powder makers.
