Saw Plametto
The botanical name for Saw Palmetto is Serenoa Repens, while its genus / species name is Serenoa repens.

Its benefits on prostate gland can be traced back centuries where the aborigines of Florida depended upon the
berries as a staple food item and was included in the Indian medicine mans array of healing herbs. In 1898, Edwin
Hale, M.D. described its medicinal value for relief of prostate gland swelling in his book-Saw Palmetto. Saw Palmetto
is also believed to benefit conditions like baldness, colds and coughs, sore throat, asthma, chronic bronchitis,
migraine headache etc, studies are needed to support these health benefit claims of saw palmetto.

Saw Plametto Benefits - Benign Prostatic Hyperplasia
Recently an extract derived from the Saw Palmetto berry has been used to treat male genitourinary problems. It
grows naturally in the southeast United States, and has been used as a folk remedy for this issue for hundreds of
years. In recent years science has confirmed that Saw Palmetto is an effective herbal remedy in helping to treat the
common symptoms associated with and enlarged prostate gland.
Benign Prostatic Hyperplasia (BPH). Benign
Prostatic Hyperplasia is a common occurrence in almost all men over 50.

Researchers at University of Messina, Italy, reported the combined use of saw palmetto, selenium and lycopene
gave a better benefit than saw palmetto alone to prevent hormone dependent prostatic growth in a study of rats. [9]

Saw Palmetto Benefits - Prostate Cancer
Researchers recently demonstrated that oral administration of saw palmetto to TRAMP mice increases apoptosis,
and reduce tumor grade and frank tumor incidence. These results support the idea that dietary supplementation
with saw palmetto extract could be effective in preventing or delaying the onset and progression of prostate cancer.

A study of 369 men finds that the supplements work no better than placebo. The trial started men out at 320 mg,
doubled the dose at six months, then tripled the dose to 960 mg daily after one year. However, both groups have
similar results and the result is only a slight improvement. [11]

Saw Palmetto Hair Loss
Androgenic alopecia (AGA) is the most common cause of hair loss in humans. AGA hair loss is characterized by the
structural miniaturization of androgen-sensitive hair follicles in susceptible individuals and is anatomically defined
within a given pattern of the scalp. Saw Palmetto may benefit AGA hair loss. Biochemically, one contributing factor
of this disorder is the conversion of testosterone to dihydrotestosterone via the enzyme 5-alpha reductase (5AR).
This metabolism is also key to the onset and progression of benign prostatic hyperplasia (BPH). In a study,
liposterolic extract of saw palmetto and beta-sitosterol were effectively to treat this type of hair loss. [5] Chittur S
and co-workers at Advanced Restoration Technologies, Inc. further demonstrated that saw palmetto extract
combined with blockade of inflammatory processes could represent a novel two-pronged approach in the treatment
of AGA hair loss with improved efficacy over current modalities. [6]

Saw Palmetto Acne
A sebum control cream containing polyphenol-rich extract from saw palmetto, sesame seeds, and argan oilIn was
shown its efficacy or benefit of reducing the greasiness of oily facial skin. [7] But insufficient evidence to support the
claim that saw palmetto benefit conditions like acne.

Saw palmetto appears to be as effective as finasteride, with limited side effects. There is no known drug interactions
with saw palmetto and the side effects reported are minor and rare. [1] Also, In a review of 21 trials, Wilt T and
co-workers at General Internal Medicine, Minneapolis, concluded that the side effects related to Serenoa repens
were mild and infrequent. [3]

In a study of 155 men with clinically diagnosed benign prostatic hyperplasia, subjects consumed Permixon 160 mg
(lipidosterolic extract of Serenoa repens; twice daily for 2 years). Researchers found maximum urinary flow
improved significantly and Prostate size decreased. Sexual function remained stable during the first year of
treatment and improved significantly during the second year. 10 adverse events were reported in nine patients. The
researchers claimed that the long-term efficacy and tolerability of saw palmetto extract was demonstrated. [2]

Medlineplus (September 14, 2011) reports saw palmetto side effects include dizziness, headache, nausea,
vomiting, constipation, and diarrhea. Saw palmetto side effect may further include impotence, however, the rate of
these side effects is similar to the rate for users taking placebo. There is also some concern that saw palmetto
might cause liver or pancreas problems in some people, but information is not sufficient to show the relationship.
Finally, saw palmetto seems to decrease estrogen level and slow blood clotting. Users must be careful if they are
also taking estrogen pills, anticoagulants, and antiplatelets.

A recent report (August 25, 2011), a case of acute pancreatitis potentially associated with saw palmetto use has
been reported. Users must be alert to this potential side effects. [8] In fact, as early as 2006, there was a similar
report about saw palmetto side effect of pancreatitis from St. Agnes Healthcare. [10]

The recommended dosages for early stages of Benign Prostatic Hyperplasia is 160 mg, twice a day. The product
should be standardized and contain 85 - 95% fatty acids and sterols. These fatty acids and sterols are believed to
be the active components in Saw Palmetto that may nutritionally support healthy prostate and urinary function.
Extract usually contains oleic acid, lauric acid, myristic acid and palmitic acid, plant sterols (beta-sitosterol,
campesterol, stigmasterol and cycloartenol), free fatty alcohols and monoglycerides.Other relevant articles in this
