Drug
Interactions:
None known. See
Caution. However, since mechanism of action of Saw
Palmetto is similar to Finasteride (Proscar) it may be important
not to use those two medications concurrently due to the possibility
of an additive effect. Conversely, San Palmetto's anti-androgenic
activity could diminish the effect of therapeutic androgens. Also,
may interact negatively with hormone replacement therapy.

| Pharmacology
|
|
Saw
Palmetto was once widely used for urogenital ailments prior to
World War ll. Since then, European Scientists have conducted studies
on Saw Palmetto and recognized its' therapeutic value in Benign
Prostatic Hyperplasia. [BPH ].
Studies
have shown that Saw Palmetto extract reduced the uptake, in tissue
specimens ,of both testosterone and dihydrotestosterone (DHT)
by more than 40%. Other studies have shown that Saw Palmetto inhibits
the conversion of the less active testosterone to the more active
DHT by inhibiting the enzyme 5 alpha reductase. Hence Saw Palmetto,
by blocking the binding of DHT to nuclear receptor sites and inhibiting
the conversion of testosterone to DHT ,decreases the proliferative
effects of DHT on prostate cells (a mechanism similar to Finasteride
- Proscar ,but without its side-effect. Proscar may cause hypotension
and lethargy).
Saw
Palmetto also inhibits the cyclo-oxygenase and 5-lipoxygenase
pathways, which results in prevention of biosynthesis of inflammation
producing substances such as prostaglandin and leukotrienes. It
also inhibits the arachidonic acid cascade, and all these account
for the anti-inflammatory and anti-edematous properties of saw
palmetto.
Together,
the anti-androgenic and anti-inflammatory effects of Saw Palmetto
account for its effectiveness in treating BPH. Placebo-controlled
double blind clinical studies in over 2,000 patients in Germany
confirms the effectiveness of Saw Palmetto in BPH.
Saw
Palmetto has become a very popular herb because of its efficacy,
low potential for toxicity and an increasing population of middle-aged
men seeking relief from symptoms of BPH - namely urinary frequency,
dysuria and nocturia. As a result of its efficacy and low potential
for toxicity, it is now prescribed as a first line treatment for
mild BPH. by many physicians. It is important to note that Saw
Palmetto does not reduce the size of the prostate, although it
relieves the urinary symptoms. Also, men should be aware that
lower urinary tract symptoms ,that may be relieved by Saw Palmetto
,could be symptoms of Prostate Cancer. Such symptoms include urinary
frequency, inability to urinate, trouble starting or holding back
urination and a weak or interrupted flow of urine. Men experiencing
these symptoms should be evaluated by their physician.
In
the U.S., a prescription drug called FINASTERIDE (proscar) with
exactly the same mode of action has been approved for prostatic
cancer and also for male pattern baldness .

| Origin |
|
Saw
Palmetto is a small palm tree with large leaves and large deep
red blackberries found along the North American Atlantic Coast
(Florida). The berries were used by American Indians in the treatment
of genito urinary tract problems including enuresis, nocturia
and urinary tract disorders. Recent clinical trials have been
shown that Saw Palmetto berries are very effective the treatment
of Benign Prostatic Hyperplasia.
|
| Processing |
|
The
large deep red blackberries of the Saw Palmetto are picked when
ripe, then partially dried, and prepared into a purified fat soluble
extract and processed into tablets or capsule form.
