„Traditionally, the milky latex of V. solanacea can be applied to treat ringworm and other skininfections, including sores, cuts and wounds. From leaves and seeds of V. solanacea, cardiac glycosides, fatty acids and triterpenes have been isolated. From the root bark, essential oils have been identified. Leaves and barks of V. solanacea have been reported to possess anticancer, antimicrobial, analgesic, anti-inflammatory, anti-diarrhoeal and cardiotonic properties, and display toxicity to brine shrimp but not to rats.“
