Saw palmetto, a plant native to the southeastern United States, has been used for centuries in traditional medicine to treat various health conditions, including urinary problems and prostate issues. However, with the rise of its popularity as a dietary supplement, concerns have been raised about its potential impact on kidney health. In this article, we will delve into the available research and explore the question: does saw palmetto damage kidneys?
What Is Saw Palmetto?
Saw palmetto, also known as Serenoa repens, is a small palm tree that grows in the southeastern United States. The berries of the plant have been used in traditional medicine for centuries to treat various health conditions, including urinary problems, prostate issues, and even hair loss. The berries contain a mixture of fatty acids, flavonoids, and phytosterols, which are believed to be responsible for their medicinal properties.
How Does Saw Palmetto Work?
Saw palmetto is believed to work by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone that has been linked to prostate problems and hair loss. By blocking this conversion, saw palmetto may help to reduce the size of the prostate and alleviate symptoms of benign prostatic hyperplasia (BPH), a condition that affects millions of men worldwide.
The Concerns About Saw Palmetto And Kidney Damage
Despite its potential benefits, saw palmetto has been linked to kidney damage in some studies. The concerns about saw palmetto and kidney damage are based on several case reports and animal studies that suggest that the herb may cause kidney problems in some individuals.
Case Reports Of Saw Palmetto And Kidney Damage
There have been several case reports of saw palmetto causing kidney damage in humans. In one case report, a 65-year-old man developed kidney failure after taking saw palmetto supplements for several months. In another case report, a 55-year-old woman developed kidney damage after taking saw palmetto supplements for several years.
Animal Studies on Saw Palmetto and Kidney Damage
Animal studies have also suggested that saw palmetto may cause kidney damage. In one study, rats that were given high doses of saw palmetto developed kidney damage and inflammation. In another study, mice that were given saw palmetto developed kidney problems and had elevated levels of creatinine, a waste product that is normally filtered out by the kidneys.
What Do The Experts Say?
Despite the concerns about saw palmetto and kidney damage, many experts believe that the herb is safe when used properly. The National Institutes of Health (NIH) has stated that saw palmetto is “generally considered safe” when used in recommended doses. The NIH also notes that saw palmetto may interact with certain medications, including blood thinners and diabetes medications, and that individuals with kidney or liver disease should use the herb with caution.
