What is saw palmetto? 

Saw palmetto, botanically known as Serenoa repens, is a small palm tree endemic to the south-eastern parts of America especially Florida and Georgia. It has a long history of medicinal use for centuries in traditional and folk medicines used by native Americans in the southeast parts of the U.S.  

The herbs, berries, and extracts are used to prepare saw palmetto supplements. It has been found to be highly beneficial in the treatment and prevention of polycystic ovarian syndrome (PCOS), hormone imbalances (testosterone or estrogen), and benign prostatic hyperplasia (BPH). 

Besides, saw palmetto has an incredible ability to promote genitourinary health in both males as well as females. It can improve sexual vigor, libido, and chronic pelvic pain syndrome as well.    

How saw palmetto can help with PCOS 

Saw palmetto contains liposterols (a group of certain fatty acids) such as linoleic, oleic, myristic, and lauric acids. All of these fatty acids play an important role in inhibiting the 5 alpha-reductase enzyme that transforms testosterone into its most potent form DHT (dihydrotestosterone). 

Excess androgen levels are the hallmark of PCOS. Saw palmetto has been found to be effective in reducing the uptake of androgens, including both testosterone and its active form DHT. 

Another causative factor of PCOS is prolactin, which has been found generally high in women with PCOS and is a dominant cause of infertility and amenorrhea. Excess prolactin can restrain follicle maturation, and ovulation, and increase the risk of developing ovarian cysts. Studies suggest that saw palmetto is capable of blocking prolactin receptors on ovarian cells. 

Saw palmetto can prove highly beneficial for women with PCOS by inhibiting 5 alpha-reductase enzymes and reducing elevated androgens and prolactin which are leading causes of PCOS.     

How to use saw palmetto

Saw palmetto supplements are available in various forms including liquid extraction and dried extract capsules. Though dosages of saw palmetto may vary depending on the severity of the symptoms and other associated health conditions, it appears most effective at 160 mg to 320 mg daily doses. 

But it’s recommended to consult with a naturopathic doctor to ensure what doses would be the best for your specific health conditions. 

Precautions and side effects 

Saw palmetto supplements are generally considered safe for most people. Common side effects are mild and reversible. They may include headache, nausea, diarrhea, vomiting, decreased libido, fatigue, and vertigo. But these side effects are not common for all. 

Saw palmetto may interact with other supplements or medications even though there is no evidence. Pregnant, breastfeeding women, children, and those with medications should consult with their healthcare providers before taking any supplements. 

Final words 

Saw palmetto has been used for centuries in folk and traditional medicines of southeast America. Though it is mainly indicated for prostate-related issues, it has an incredible ability to lower elevated androgens and prolactin, two leading causes of PCOS in women. It can reduce both testosterone as well as its most active form DHT (dihydrotestosterone), making it highly beneficial for the treatment and prevention of hormonal imbalances seen in women with PCOS. 

Saw palmetto may interact with other supplements or medications and may also cause some mild side effects like vertigo, nausea, and vomiting. Therefore, consult with a professional naturopathic practitioner before starting the saw palmetto.
