What is it?

Saw palmetto is a plant and the fruit is the basis for supplements.

Does it occur naturally in the body?

No.

What are the claims?

Saw palmetto is primarily promoted as a way to decrease symptoms or even cure an enlarged prostate (benign prostatic hypertrophy, BPH).

Saw palmetto is also marketed as a treatment for prostate infections and to treat prostate cancer.

Less well known uses it's promoted for include a way to treat asthma, chronic bonchitis, colds, coughs, chronic pelvic pain syndrome, reduce baldness, reduce complications prior to surgery, to increase urine flow (as a diuretic), to relieve migraines, as a relaxant (sedative), for sore throats and as an aphrodisiac.

Does it work?

In smaller studies, it has shown minimal benefit for sufferers of BPH. Small studies seemed to show modest benefits, but as the studies were scaled up the benefit was no more than that offered by a placebo. There are no large scale studies that show saw palmetto to help with BPH.

Prior to surgery, researchers found that taking 320 mg of saw palmetto daily for two months prior to prostate surgery could reduce blood loss, surgical complications and recovery time. Unfortunately the study was not successfully replicated and additional studies that prescribed lower doses prior to surgery showed no beneficial effect. As studies have scaled up, the benefits appear to be no better than a placebo.

As for the other potential benefits or saw palmetto? There are no reliable studies that show it can help with anything else it's being marketed for.

What are the dangers?

The side effects reported by people taking saw palmetto appear mild, including dizziness, headache, nausea, etc. But those symptoms don't appear any more often in subjects taking saw palmetto than they do to people taking a sugar pill.

It is ironic that the only study that seemed to show a potential benefit was one where people took it before surgery. Saw palmetto has been shown to slow how fast blood clots. That could mean more bleeding during and after surgery, leading to additional complications. Doctors generally recommend you stop taking saw palmetto supplements at least two weeks before any scheduled surgery.

DANGERS FOR WOMEN: Saw palmetto acts as a hormone. Women who are pregnant or breast feeding may be putting their children at risk if they take it. Saw palmetto also decreases the effect of estrogen in the body. Women who are taking birth control pills with estrogen in them, may experience a lowering of the effectiveness rate of the birth control.

Without any long term studies to rely upon, scientists can only make educated guesses on what other problems may occur. There are documented cases of people who took saw palmetto suffering from liver or pancreas damage. Unfortunately because saw palmetto is a supplement, there are no guarantees of drug levels in any bottle or independent testing for contaminants. It's entirely possible the reported potential problems were from adulterated or fraudulent supplements.

Without any federal oversight, the consumer is completely at the mercy of the supplement manufacturer and few have proven they can be trusted. (Remember in a 2014 study, 1/3 of the "herbal supplements" researchers purchased, didn't have any of the advertised ingredients in the bottle. Product substitution was revealed in 30 of the 44 products tested.)

The Bottom Line

There does not appear to be any benefit for people to take saw palmetto supplements. In addition there are potentially serious side effects for people taking it before surgery or for nursing or pregnant women.

Unless prescribed by a doctor for a specific medical condition, we cannot recommend the supplement saw palmetto.
