Barberry's medicinal value has not been officially recognized. It is considered obsolete as a drug, and its use is discouraged. Nevertheless, the berries appear to be effective for boosting the immune system and combating urinary tract infections, while the root seems to serve as a remedy for indigestion and problems with the liver and gallbladder.
Barberry has been used for a variety of other problems as well, including enlarged spleen, diarrhea, tuberculosis, hemorrhoids, kidney disease, gout, arthritis, low back pain, malaria and parasite infections. However, its effectiveness for all these conditions remains in doubt, and its use is not recommended.
