Saw palmetto has been getting a lot of attention recently as a natural
cure for hair loss. Is there any evidence that it works? While it is
true that saw palmetto is a natural product and an herbal supplement;
I think it's important to discuss the dangers behind what I call the
"herbal mentality." It's easy to fall into the belief that plant
extracts are "natural" and that substances that are plant-based are
naturally healthier for us. However, many of our legal (and illegal)
drugs are based on plant extracts! Although we tend to think of
natural substances as being harmless and good for us, there are some
dangers to consider-for example, if someone told you that "poppy seed
extract" was a great "natural" way to get a good night's sleep, they
would only be telling part of the story.

Many narcotics, poisons, and even legitimate medical treatments come
from leaves and roots, rather than laboratories. Unfortunately, the
wave of new-age medicine and do-it-yourself healing has given more
people the opinion that they can cure themselves with a pamphlet and a
few drops of essential oils. I strongly believe that natural remedies
can work, and that is exactly why I believe that people should really
know what they're doing before they start to throw back a bottle of
something that claims to grow hair (and shrink an enlarged prostate,
and grow breast tissue, and cure pelvic pain, and regulate a menstrual
cycle-assuming that you are even designed to have one.)

Moving on to my second concern-if it does one thing, how do you know
that's all it does? Minoxidil (one of the only FDA approved hair
growth medications) was originally developed as a treatment for high
blood pressure. Researchers discovered that it created the growth of
thicker, darker bodily hair; this strange side-effect ballooned into a
marketing opportunity. Certainly, many men and women are happy for
this unusual side-effect, but I think it's wisest to stick with tested
treatments. I wouldn't want to be the man who takes saw palmetto for
hair growth and discovers that it also increases breast tissue!

In the case of saw palmetto, there are claims that it inhibits
dihydrotestosterone or DHT (the androgenic hormone that leads to hair
loss). However, manufacturers mostly advertise it as an aid in urinary
function and men's prostate health; it has been specifically tested
for its effects on the urinary symptoms of an enlarged prostate gland-
however, according to the National Center for Complementary and
Alternative Medicine, there has been no conclusive evidence of any
real benefit for that condition either.

A final consideration with any treatment containing herbal extracts is
that the manufacturing process for herbal supplements is not as
stringent as it is within the pharmaceutical industry. It is likely
that different batches or brands of an herbal supplement can have very
different concentrations or levels of effectiveness. This can be a
troubling concern when it is combined with the fact that, without
clinical trials, no one knows exactly what amount is a recommended
dosage and what level would lead to an overdose. Overall, although
there may be a connection between saw palmetto and hair growth, I
wouldn't feel comfortable recommending it to anyone without clinical
trials, FDA approval, and government regulation. This will sound
harsh, but until it is government-proven, you're essentially running a
trial using your own body and your money.
