The plant is harvested from the wild for local use as a food.
A widespread and invasive plant in tropical and subtropical regions worldwide. It is toxic to livestock and very hard to control, as rootstocks less than 1 cm long can regenerate into plants. Introduced and invasive in drier habitats in southern (South Africa and Namibia) and northern (Morocco and Egypt) Africa, in South Africa classified as a noxious weed and a quarantine pest in northern Africa; also known from dry areas around the Mediterranean[
Although providing many well-known foods for people, including the potato, tomato, pepper and aubergine, most species in this genus also contain toxic alkaloids. Whilst these alkaloids can make the plant useful in treaing a range of medical conditions, they can also cause problems such as nausea, vomiting, salivation, drowsiness, abdominal pain, diarrhoea, weakness and respiratory depression[
