Saw palmetto is a traditional herbal medicine used to relieve urinary discomfort in men with an enlarged prostate (aka Benign Prostatic Hypertrophy or BPH) based on traditional use.

The saw palmetto plant is a small palm tree with saw-tooth-like leaves, hence the name. The berries contain a large number of natural, botanical nutrients including a variety of fatty acids and phytosterols.

  • How does it work?

    Traditionally saw palmetto is known to shrink the inner lining that puts pressure on the tubes that carry urine. As men get older the prostate gland can enlarge causing urinary discomfort. By the age of 70, approximately 8 in 10 men will have an enlarged prostate gland.(i)

    Saw palmetto is used to relieve these BPH symptoms:

    • Frequent urination (especially at night)
    • Incomplete sensation
    • Weak/interrupted stream

    One study confirmed that saw palmetto can ease the symptoms of BPH(i)(ii) It showed that 21% of men experience dramatic improvements of BPH symptoms after two months and 46% of men experience dramatic improvements of BPH symptoms after six months.

  • What is THR?

    The THR certification mark is a type of trade mark. It indicates that the herbal medicine has been registered with the MHRA under the Traditional Herbal Registration (THR) scheme and meets the required standards relating to its quality, safety, evidence of traditional use and other criteria as set out under the Traditional Herbal Medicinal Products Directive (THMPD) 2004/24/EC.

  • Caution

    You must have been told by your doctor that you have BPH (Benign Prostate Hypertrophy). Do not exceed the stated dose. Do not take saw palmetto if you are allergic to saw palmetto fruits or any of the other ingredients or are under 18 years of age.
