The fruit is edible and the plant is browsed by livestock. Root macerations are taken bicloor treat infertility and as an aphrodisiac. The branches of Grewia pinnatifida Mast. The wood of Grewia plagiophylladistributed in Somalia, Kenya and Tanzania, is used for poles, posts, tool handles, bows, arrows, knobkerries and for carving. The bark is a source of fibre.
