Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Delays Blood Clotting

According to Medline Plus, taking saw palmetto may cause bleeding and delay blood clotting, potentially put the patient at risk for bruising. Surgeons advise patients scheduled for any surgical procedure to stop using saw palmetto at least two weeks before surgery. This herb should not be taken together with anti-coagulants and anti-platelet medications, such as Heparin and Coumadin, to avoid a dangerous increase in blood-thinning. Patients with conditions such as stomach ulcers, intestinal ulcers, hemophilia and blood-clotting disorders should avoid taking saw palmetto.

Liver Damage

Liver damage is one of the possible risks of saw palmetto, as described in Medline Plus. The liver, the body’s largest internal organ cleans and filters the blood of alcohol and toxins. These materials come from various sources such as food, beverages, medications and dietary supplements. Materials that damage the liver are called hepatotoxic substances. Saw palmetto can become potentially hepatotoxic in some patients, most especially for those who have pre-existing liver conditions. Patients who develop liver damage from taking saw palmetto exhibit loss of appetite, clay-colored stools and jaundice or yellow discoloration of the skin and eyes.
