Editor's Note: The homeopathic remedy described here is contradicted by the warnings found on most toxic/poisonous plant lists and websites, most of which state that all parts of Solanum elaeagnifolium are toxic to humans and livestock.

Ingestion can cause severe to lethal gastrointestinal and musculoskeletal problems, as well as birth defects.
