Name and Origin
Saw palmetto (Serenoa repens) is a small palm native to the southeastern regions of North America, particularly in Florida. It gets its name from the sawtooth-like spines that cover its stems. Indigenous people of North America, grew it in sandy soil and it has been used for centuries in traditional medicine, especially by Native American tribes (Petre & McGrane, 2019). As it is derived from the ripe berry-like fruit of the American Dwarf Palm, it is often used as a supplement for suppressing conditions such as benign prostatic hyperplasia (BPH) and improving hormonal health. This herb is also used for reproductive concerns and has been shown to benefit people with genitourinary disorders. Additionally, saw palmetto extract has properties as an aphrodisiac, and as a sedative. Finally, saw palmetto is thought to improve hair loss and improve certain symptoms of androgen deficiency, and even helps to treat low testosterone.
Health Benefits
Saw Palmetto is most commonly known for supporting prostate health, especially in men with benign prostatic hyperplasia (BPH). It may help reduce urinary symptoms like frequent urination and nighttime urgency. Some studies also suggest it support androgenic alopecia and reduce inflammation (Petre & McGrane, 2019).
Expanded Health Benefits
More health benefits of Saw Palmetto:
❖ Benign Prostatic Hyperplasia (BPH): Saw palmetto is most widely recognized for its potential to alleviate symptoms of benign prostatic hyperplasia, a condition in which the prostate gland becomes enlarged, leading to urinary difficulties. Saw palmetto helps reduce urinary symptoms and improve flow.
❖ Hormonal Balance: Saw palmetto may inhibit the conversion of testosterone to dihydrotestosterone (DHT), a hormone linked to hair loss and prostate enlargement. This property is why it is often used in supplements aimed at promoting hair health.
❖ Hair Loss Prevention: Due to its potential effects on DHT levels, saw palmetto is sometimes used as a natural treatment for androgenetic alopecia (male and female pattern baldness).
❖ Anti-Inflammatory Effects: Saw palmetto may have anti-inflammatory properties, which can contribute to its benefits for prostate health and overall well-being. Reducing inflammation helps with various conditions affected by chronic inflammation.
❖ Urinary Health: Some studies suggest that saw palmetto can help improve urinary function and reduce the frequency of nighttime urination (nocturia) in men with BPH, enhancing overall quality of life.
❖ Potential Sexual Health Benefits: Some men report improvements in libido and sexual function when using saw palmetto, although scientific evidence on this is limited.
❖ Antioxidant Properties: Saw palmetto contains antioxidants that may help protect cells from oxidative stress, contributing to overall health.
