| Pharmacology
|
|
Active
principles consist largely of cascarosides A,B,C and D with anthroquinone
glycosides in minor amounts. These active substances stimulate
peristalsis locally in the large intestine and also act indirectly
by circulating in the blood stream and stimulating a nerve center
to trigger a laxative effect.
Cascara
also helps restore tone to the colon and thereby overcome laxative
dependence in the elderly.
It
is also safe and effective for detoxifying and cleansing programs,
as opposed to harsher laxatives e.g. senna.
Cascara
can be used as an effective chelating agent to prevent the occurrence
of calcium based kidney stones .

|
Active
Ingredients:
|
 |
Free anthroquinone and its sugar derivatives.
|
 |
Hydroxy anthracene derivatives (HAD)
|
|
| Origin |
|
It
is a small to medium-sized tree native to the American Northwest.
It has thin and pointy dark green leaves that fall in autumn,
small purplish -black fruits, and a reddish brown bark with gray
or white lichen patches The bark is used medicinally.
|
| Processing |
|
The
bark should be aged at least one year before being processed in
order to allow the reduced glycosides (Anthrones) with their harsh
laxative action to be converted to milder oxidized forms. The
Aged dried bark is then pulverized. Standard amount of the active
ingredient should be 20-30% hydroxyanthracene derivatives (HAD).
