''Solanum giganteum'' Jacq. comprises about 1000 species and has a disjunct montane cosmopolitan distribution , except in Africa and is also known from tropical Asiaboreal, Australia alpine and South Americaaquatic habitats. In East About 110 species are found in tropical Africa the woolly hairy underside . The principal centre of the leaves diversity is used to clean wounds located in Central and the glabrous upper side is used to dress wounds. The fruits are edible but bitter South America, with secondary centres in Africa and are used to treat throat ulcers and to curdle milkAustralia. In Uganda powdered dry leaves are added to bath water to overcome sleeplessness. In India ''Solanum giganteum'' is planted as a shade treehas been subdivided into 7 subgenera and numerous sections and series.
''Solanum goetzeitettense'' Dammer occurs from Kenya southwards to Zambia is a polymorphic species and Mozambique2 varieties are distinguished, based on differences in hairiness. In Kenya It is placed in the ''Solanum giganteum'' group of the section ''Oliganthes'' of subgenus ''Leptostemonum'', a hot poultice group of pounded leaves is used about 10 species, all of them restricted to reduce swellings and to draw out abscessessub-Saharan Africa. Two other species of this group have medicinal uses in tropical Africa.
