Saw palmetto is a small palm that is commonly found in the southeastern United States. It has been used as a herbal medicine through the centuries. The extract of saw palmetto berries has been used for treating diseases, like benign prostatic hyperplasia and urinary tract infections. It is suggested that, this herb is useful in the treatment of androgenic alopecia (male pattern baldness), for breast enlargement, and for increasing sex drive. Even though, there is no scientific evidence to prove the efficacy of the herb, saw palmetto is widely used as a herbal supplement.
Though the herb is highly popular, and is said to be effective as a herbal remedy; it is not free of side effects. The following are some of the possible adverse effects of saw palmetto extract.

  • Use of saw palmetto may lead to depression, insomnia, high blood pressure, and hearts problems too.

Apart from the side effects, intake of saw palmetto may also cause drug interactions. The herb should be avoided by men, who are using medication that affect the sex hormones. Women should abstain from taking saw palmetto extract, if they use birth control pills or undergo hormone therapies.
