Pygeum is a large evergreen tree found in Africa. It is also known as African Plumb. The bark of the tree is the part mostly used for medicinal purposes. Pygeum is an herb that is primarily used for urinary tract problems, especially those caused by an enlarged prostate. It contains terpenes that are anti-swelling so they aid in reducing the enlargement of the prostate. It is often combined with saw palmetto when used for enlarged prostate. It may also help prevent prostate cancer. Some animal studies indicate that it can increase sperm count in males. It is also sometimes used to treat impotence, fevers, kidney disease and malaria. It may help with urinary tract infections and erectile dysfunction. It has also been used as a tonic to treat hair loss. It may help with some cases of stomach upset. 
    Pygeum is considered generally safe, but may cause diarrhea, constipation or nausia in some sensitive individuals.
