GRAVIOLA Recent research has noted Gravilola's ability to target and destroy malignant cancer cells in 12 different types of cancers including breast and liver cancers. It is selective and only kills cancer cells and leaves healthy cells unharmed. It has also been found to improve the immune system, control blood sugars and diabetes, and improve the digestive system. It is high in fiber, assists in weight loss, and is high in anti-oxidants thus neutralizing free radicals. It has also been found to kill the Herpes Simplex 2 virus.
