About
Solanum aculeastrum is commonly known as soda apple, sodaapple nightshade, goat apple, poison apple, or more ambiguously as "bitter-apple". It is a poisonous nightshade species from Africa and only distantly related to true apples. The term "soda apple" probably derives from "Sodom apple", modified due to the fruit's detergent properties.
Uses
Because of its dense growth and prickly nature, soda apple is used as a hedge and living barrier for containing livestock. It is often used as a soap replacement, as it is high in saponin. Traditional Zulu practices use the fruit - fresh, boiled, or charred - in herbal medicine to treat a wide variety of afflictions, including cancer, toothaches, and ringworm. The Taita tribe of southern Kenya use the ripe yellow fruit to treat paronychia. The roots are chewed and, the sap ingested to alleviate stomach aches.
