Uziza seeds (from the plant Piper guineense) are widely used as a spice in West Africa and have been used in traditional medicine for generations. They contain compounds such as piperine, flavonoids, and essential oils that may contribute to their health effects.
While uziza seeds are nutritious, many of the medicinal claims (such as treating infertility or serious illnesses) come from traditional use or animal studies and have not yet been confirmed by strong human clinical trials.
