Saw palmetto is a type of
palm tree that grows in the southeastern United States.
of the saw palmetto plant contains a compound that may reduce the symptoms of
benign prostatic hyperplasia (BPH), which is a
noncancerous enlargement of the prostate gland. Symptoms of an enlarged
prostate include dribbling after urination and getting up many times during the
night to urinate.
First and foremost, we're trying to bring as much attention as possible to
kidney disease; educate the general public about risk factors such as high
blood pressure, diabetes, and family history; share the warning signs and the
importance of regularly seeing your doctor; and highlight organ donation. So
many people have kidney disease and just don't know it, which is why it's so
important to create a relationship with your doctor. The National Kidney
Foundation provides free kidney screenings...
From the 1870s until 1950, saw palmetto was a
common treatment for prostate and other urinary problems. After 1950, saw
palmetto was no longer recognized as a drug in the United States. It is still
used in Europe as a treatment for BPH and is approved by the German Commission
E. The Commission E evaluates herbal treatments for their safety and efficacy
(how well they work).
Experts disagree on whether
saw palmetto improves men's symptoms of BPH. Experts also don't clearly
understand how saw palmetto may improve symptoms of BPH. It might stop the
growth of the prostate or even make it smaller. This is how finasteride, a
medicine commonly prescribed to treat BPH symptoms, works.
Most studies show that taking saw palmetto doesn't help symptoms of BPH any more than taking a placebo.1
A review of studies done on saw palmetto showed that men who took saw palmetto had some improvement in nighttime urination. But when only the best studies were included in the review, men who took saw palmetto had no difference in symptoms, urine flow, or nighttime urination compared with men who took a placebo.2
In another study, men who took even higher doses of saw palmetto had no difference in BPH symptoms, urine flow, or nighttime urination compared with men who took a placebo.3
Is saw palmetto safe?
Few problems have been
reported among men taking saw palmetto. But some men may experience stomach
problems. Saw palmetto is less likely than finasteride to cause difficulty in
getting an erection.
