Piper guineense, known as African black pepper, Ashanti pepper, or Uziza (in Nigeria), is a West African spice used in cooking and traditional medicine for digestion, inflammation, postpartum recovery, libido, coughs, and antimicrobial effects, with its leaves and seeds rich in beneficial compounds like flavonoids and alkaloids.
Ashanti pepper (Piper guineense, family Piperaceae) is an evergreen climbing plant whose woody stems reach 4 to 20 metres, clinging to trees by roots that grow along the stem. Its small berries grow in clusters on slender stalks and are dried for use as a spice. Male and female flowers are borne on separate plants, so both are needed for fruit.
It is a plant of moist places: evergreen rainforest, forest edges and gallery forest along rivers, at 750 to 1,650 metres. Its range runs across tropical Africa from Senegal to southern Sudan and south to the Democratic Republic of Congo, Zambia and Tanzania. In savanna country it is found mainly in gallery forest and damp places along streams. It is grown from seed.
