May I add from http://en.wikipedia.org/wiki/Solanum_torvum :
It is also known as Devil's Fig, Prickly Nightshade, Shoo-shoo Bush, Wild Eggplant, Pea Eggplant, Pea Aubergine, susumba, boo, terongan, tekokak, berenjena cimarrona, berenjena de gallina, berenjena silvestre, tabacón, pendejera, tomatillo, bâtard balengène, zamorette, friega-platos, sundaikkai (Tamil: சுண்டைக்காய்), Thibbatu (Sinhala), makhua phuang (Thai: มะเขือพวง), and many other names (Howard 1989, Little and others 1974, Pacific Island Ecosystems at Risk 2001). [ In Malaysia, it is called terung pipit.]
In Jamaica this berry is called susumba,or gully beans, and is usually cooked in a dish along with saltfish and ackee. It is believed to be full of iron (it does have a strong iron like taste when eaten) and is consumed when one is low in iron.
Turkey berry contains a number of potentially pharmacologically active chemicals including the sapogenin steroid, chlorogenin.
Aqueous extracts of turkey berry are lethal to mice by depressing the number of erythrocytes, leukocytes and platelets in their blood (Tapia and others 1996). A related chemical, cholecalciferol, is the active ingredient in a number of commercial rodentacides.
Extracts of the plant are reported to be useful in the treatment of hyperactivity, colds and cough, pimples, skin diseases, and leprosy.
Methyl caffeate, extracted from the fruit of S. torvum shows an antidiabetic effect in streptozotocin induced diabetic rats.
A Google search with "Solanum torvum research" lists a good number (25,800) of studies into pea eggplant (but I didn't go on ;-)
(And thank you for your very kind words.)
