Herb strength (Magnesium Deficiency Causes?)

[Guest guest]

Every thing that Vitoria said plus, one needs to

consider the time since processing the herb for

consumption.

 

Common understanding in the Western herbal

practice is that once an herb has been gathered

the maxium quality of medicine deteriorates

after a given amount of time.

 

In Wertern herbalism;

Roots, barks, and seeds have a 3 year shelf life.

Leaves and flowers have a one year shelf life.

 

If you grind the herb it has approximately 3 to

6 month shelf life.

 

If you make a decoction or infusion, refrigerated

it is medicinally good for perhaps 24 hrs.

Tinctures are said to have indefinate shelf life as

long as they contain 20% alcohol.

 

Preserved with vinegar or glycerine, about one year shelf life.

 

Asian medicines have even more methods of processing for

consumption.

 

But my point is that if you purchase an herb in a capsul

from the health food or drug store,

how do you know how long its been from harvest to

consumption?

They tend to put a 3 year expiration date on the product

that relates to the time they anticipate the product being

placed in the store.

 

Chances are with many large herbal companies, they

bought the herb when prices were low and stored it in

their warehouse until the store placed their order for it.

The date of experation goes on when its bottled and

shipped to the store.
