1. Treats Benign Prostatic Hypertrophy (BPH)
The most common form of an enlarged prostate is benign prostatic hyperplasia - or BPH. The prostate gland can become inflamed or enlarged as men get older. The prostate then compresses the urethra, leading to difficulty with urination that results in bladder infections or bladder stones. BPH can be caused by a variety of circumstances, including hormonal changes (such as excess estrogen), deteriorating blood vessels and a zinc deficiency.
The American Urological Association reports that by the age of 60, over 50 percent of men will have BPH, and by age 85, 90 percent of men will have this condition. To add to this, one-fourth of these men will develop moderate to severe lower urinary tract symptoms that will greatly affect their quality of life.
Research shows that saw palmetto inhibits testosterone from binding to and stimulating prostate cells, which reduces the multiplication of prostatic cells and prostatic enlargement. Other treatments for BPH, alpha blockers and 5-alpha-reductase inhibitors cause sexual dysfunctions themselves - while saw palmetto is a natural supplement that doesn't have a long list of side effects. That makes it one of the best sources to increase testosterone naturally and improve prostate health the natural way.
One 2012 study conducted in Switzerland analyzed 82 patients in an eight-week trial; the patients took one capsule of 320milligrams saw palmetto extract daily. At the end of the treatment, the International Prostate Symptom Score was reduced from 14.4±4.7 to 6.9±5.2. Investigators' and patients' assessments confirmed the good efficacy, and treatment was very well-tolerated and accepted by the patients.
2. Reduces Risk of Prostate Cancer
A systematic literature review of 11 studies identified saw palmetto supplements as one of the five commonly used forms of alternative medicine by men with prostate cancer.
Saw palmetto supplements work as 5-alpha reductase inhibitors - meaning they slow down the conversion of testosterone to DHT by blocking the enzyme and preventing its formation. According to research, DHT is responsible for prostate enlargement, which may be a cause of prostate cancer.
The science is still unclear on this matter, but studies on two 5-alpha reductase inhibitor prescriptions, Finasteride (Proscar) and Dutasteride (Avodart) found that men taking either drug were less likely to develop prostate cancer after several years than men getting an inactive placebo. The problem lies in the side effects of these medications - they can cause sexual side effects, such as lowered sexual desire and impotence.
Saw palmetto, on the other hand, can also inhibit DHT and help with urinary problems from BPH, such as trouble urinating and leaking urine, plus it regulates your testosterone levels, helps with libido and works as a natural remedy for impotence.
Studies have also found that saw palmetto inhibits the growth of prostatic cancer cells and may destroy dangerous cells. A study conducted at the Department of Biochemistry and Molecular Biology in Beijing found that saw palmetto induced growth arrest of prostate cancer LNCaP, DU145 and PC3 cells and down-regulated DHT, the hormone that leads to prostate enlargement.
Another interesting note about saw palmetto is the research that has been done to measure its effect on post-surgery recovery time. Prostate surgery (known as transurethral resection of the prostate or TURP) can require a lengthy recovery period, but research shows that taking 320 milligrams of saw palmetto daily for two months before prostate surgery can reduce the time spent in surgery. It also helps with blood loss, the development of problems during surgery and the total time spent in the hospital.
3. Helps with Hair Loss
Saw palmetto extracts and supplements work as hair loss remedies because they keep testosterone levels balanced. As men age, the testosterone hormone is diminished and the hormone called 5α-Dihydrotestosterone (DHT) increases. The cause of hair loss is due to the hair follicles' sensitivity to DHT, which is a male androgen hormone that causes follicles to shrink, resulting in a shorter life span and decrease of hair production.
Normally after hairs fall out, another hair starts to grow from this same follicle - but if DHT is high, hair growth decreases. Saw palmetto has the power to stop the conversion of testosterone into DHT, making it beneficial for hair growth.
Although the options about saw palmetto as an effective hair growth agent are mixed, there are studies that indicate its use as beneficial. One study conducted at the Clinical Research and Development Network in Colorado tested 34 men and 28 women, aged 18-48 years, who topically applied saw palmetto extract in lotion and shampoo base for three months; the results found that 35 percent of the participants had an increase in hair density.
