Saw Palmetto extract, erectile dysfunction, side effects, as a treatment or prevention of BPH
A discussion of the role of this extract in reducing prostate enlargement
November 12 2016

Saw palmetto is an herb that has been shown in clinical studies to have beneficial effects in reducing symptoms of benign prostatic hyperplasia (BPH).  Saw palmetto (sometimes referred to as sabal in Europe) grows naturally in the southeast United States, such as Georgia, Mississippi, and particularly Florida. Not all studies with this herb have shown a benefit for BPH. Since the adverse effects from the use of this herb are minimal, many men are taking saw palmetto for prostate health and mild BPH to see if they can avoid the use of finasteride or other medications used for an enlarged prostate gland.

Saw Palmetto: Berry or extract?
When you purchase saw palmetto, you will find some bottles that provide crushed berries, not the extracts. Until we learn more about the effects of using the full contents of the berries, I recommend that you buy the extracts. The extracts will contain the actual substances that are effective in treating BPH in a much higher concentration. The berries will provide you with smaller amounts of the needed active ingredients. Whether the crushed berries have compounds that provide other benefits is not fully known at this time. If you want to take saw palmetto berries, you may need to ingest at least one or two grams a day. The ratio of the dried berry to the lipophilic extracts is usually about 10 to 1. Some users prefer to take both the extracts and the berries, thinking that there are substances within the full berries that could be beneficial. We certainly need more research in order to have a fuller understanding.

Erectile dysfunction, impotence, libido
Q. Have you, by perusing research, or through clinical experience found anything to suggest that saw palmetto may increase erectile efficiency?
A. We have not come across any research on the role of this herb saw palmetto on erectile dysfunction, but some people do notice a improvement.

Q. Does saw palmetto extract improves libido?
A. Saw palmetto extract may have a slight effect on libido and impotence treatment, but we have found Prostate Power Rx and Passion Rx to be much more potent.

Is Saw Palmetto safe?
No significant side effects have been reported in the medical literature.

For what conditions is saw palmetto useful?
The best known use is for the treatment of prostate enlargement. However, there’s a possibility that substances in saw palmetto could have an influence on a variety of body tissues, particularly skin and hair, although there is no proof at this time that saw palmetto is involved in reducing hair loss or restoring hair growth. It appears that urinary symptoms resulting from mild-to-moderate prostate enlargement respond more readily to saw palmetto than symptoms due to severe enlargement.

Does Saw Palmetto interfere with medications?
Limited research suggests that saw palmetto does not influence the ability of the liver to metabolize other drugs, for instance saw palmetto does not alter the activity of cytochrome P450.

Combining Saw Palmetto with other herbs
Research shows when taken for 3 months, a combination of natural products (rye pollen extract, saw palmetto, B-sitosterol, and vitamin E) compared to placebo can significantly lessen nocturia and frequency and diminish overall symptomatology of prostate enlargement.

Hair regrowth
Q. Will saw palmetto help regrow hair loss?
A. Probably not by itself. Saw palmetto has not been shown to be an effective hair growth herb. Finasteride is much more effective.

Heart disease, cardiac health
I am 78 yrs old and suffer from chronic prostatitis and stable angina, otherwise I look 10 yrs younger. I cannot decide whether having a heart condition I should take product with saw palmetto as a company called Nature’s Best in the UK advised me that heart patients should not take saw palmetto herbal formulas.
We have not seen such research regarding not using this herb in those with a mild or moderate heart condition but the final decision rests with your doctor. He or she may advise a lower dosage or using it every other day rather than daily but your doctor knows your condition best.

Saw Palmetto for prostate enlargement, BPH
The results of numerous studies published over the past 15 or so years indicate that saw palmetto improves symptoms in a reasonable number of patients suffering from BPH. The benefits occur often without a dramatic decrease in the size of the prostate gland. The response to saw palmetto is similar in many ways to that of Proscar, even though they probably work in different ways. In a later chapter I’ll discuss in detail how saw palmetto influences the prostate gland.

The lipidosterolic extract of Serenoa repens in the treatment of benign prostatic hyperplasia: a comparison of two dosage regimens.
Giannakopoulos X. Department of Urology, Ioannina University School of Medicine, Ioannina, Greece.
Adv Ther. 2002.
This 6-month double-blind, randomized, parallel-group study compared two dose regimens of Libeprosta, the lipidosterolic extract of Serenoa repens (saw palmetto) in 100 male outpatients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). The patients received two 80-mg tablets twice daily or two 80-mg tablets three times daily. Baseline evaluations included maximum and mean urinary flow rates, postvoid residual urine volume, and International Prostate Symptom Score (I-PSS) total and quality-of-life scores. Both regimens significantly reduced the I-PSS mean total score from baseline values (P<.001); improvements achieved statistical significance after month 3 and were maintained for the duration of the study. Significant improvements from baseline also occurred in quality-of-life scores, maximum and mean urinary flow rates, and residual urine volume (P<.05). The decrease in residual urine with both regimens was highly significant (P<.001). No significant differences in efficacy were noted between the two dose groups, and no treatment-related complications or clinical adverse events occurred. In this clinical study, the lipidosterolic extract of saw palmetto was a well-tolerated agent that may significantly improve lower urinary tract symptoms and flow measurements in men with BPH.

Q. Does maca herb help reduce symptoms of BPH?
A. Not that we are aware of.

Saw Palmetto May Help Battle Prostate Cancer
Extract from the Saw Palmetto berry, a commonly used herbal supplement taken by men with enlarged prostates, may also have anti-cancer properties, researchers announced at a meeting of The American Society for Cell Biology. “Since we knew that saw palmetto berry extract had some effect on the prostate, we decided to take this a step further. We wanted to know if the saw palmetto had any effect on prostate cancer cells,” said researchers at Children’s Hospital in Boston, Massachusetts. The research team analyzed the effects of saw palmetto berry extract on cancer cells. To accomplish this, they exposed prostate cancer cells and a generic cancer cell line to various concentrations of berry extract. The cancer cell growth in laboratory cell cultures was then monitored. About one-fifth the amount of berry extract was needed to decrease the cell growth of the prostate cancer cells compared to the amount needed to slow down the growth of the generic cancer cells.
Comments: Men who take saw palmetto for enlarged prostates now can benefit even more by having a possibly lower risk in developing prostate cancer.

Interactions with blood pressure medications
Q. Is there info available re taking saw palmetto along with prescription meds such as high blood pressure meds?
A. As far as we know, saw palmetto does not interfere to any clinical degree with other medicines.

Q. My blood pressure increased since the last time I checked. I have High Blood pressure now . I don’t know what change led to this. Since 2 weeks I am taking saw palmetto supplement capsule twice a day and I am eating 3 eggs a day and I also stopped my year long habit of drinking green Tea. Do you thing that saw palmetto had any effect on my blood pressure or cholesterol, or its due to other reasons. Can you suggest any herbal supplement or medicine that can control this. And also I ordered a pack of saw palmetto, Beta-Sitosterol and Prostate Power Rx should I continue taking these supplements or not.
A. One way to tell if the blood pressure is related to the saw palmetto intake is to stop the saw palmetto supplement and check the blood pressure over the next few days, restart the saw palmetto and check the blood pressure over the next few days, and do this cycle two or three times. Most people do not notice a blood pressure increase with saw palmetto but there could be individuals who are very sensitive to it. Also, one may consider taking one capsule rather than two saw palmetto capsules. It is impossible to say whether beta sitosterol or Prostate Power Rx will influence your blood pressure without testing them on yourself.

Testosterone effect
Q. I read frequently that supplements that increase testosterone can result in unwanted prostate growth. If male testosterone levels naturally decline with age, why does supplementing to bring these levels up to their former values cause ill effects? Why don’t 18 year old males have giant prostates?
   A. It’s difficult to know exactly what’s going on in prostate tissue and how testosterone, in different age groups, has an effect. But, it may be that the biochemical system within prostate tissue is quite able to handle high androgen levels in the youth but is not able to handle these high androgen levels too well as the person gets older thus leading to prostate enlargement.
