What Kind of Plant Is Strophanthus divaricatus? Characteristics and Value of a Toxic Medicinal Plant

Strophanthus divaricatus is an evergreen shrub or climbing vine of the genus Strophanthus in the dogbane family (Apocynaceae). It is mainly distributed in warm, humid regions such as South China and Southwest China, and is commonly found in hilly and mountainous areas, along roadsides, or at the edges of open forests. Its fruit grows in pairs, and the curved pod-like shape resembles a goat's horn, which is how the plant got its name. Each year during the flowering season it produces yellow-white funnel-shaped flowers, with the tips of the petal lobes extending into slender tails, giving it a rather distinctive appearance.

The entire Strophanthus divaricatus plant contains toxic cardiac glycosides, with the seeds and milky sap being the most toxic. Accidental ingestion may cause nausea, vomiting, arrhythmia, and other poisoning reactions, and in severe cases can even endanger life. Therefore, when encountering this plant in the wild, do not pick or taste it, and in grazing areas livestock must be prevented from eating it. After everyday contact with the branches and leaves, wash your hands promptly to avoid the sap touching your mouth, nose, or wounds.

Despite its obvious toxicity, Strophanthus divaricatus also holds a certain place in traditional medicine. Its seeds can be used to extract cardiac glycosides as raw material for pharmaceuticals, while in folk practice it is mostly used externally after being pounded into a paste to treat injuries such as bruises and swelling, as well as rheumatic bone pain. It must be emphasized that Strophanthus divaricatus is a toxic medicinal material, and oral use carries extremely high risk. Any use should be carried out under the guidance of a professional physician, and it must not be attempted on one's own.

In landscaping, Strophanthus divaricatus has distinctive flowers and lush branches and leaves, and in some areas it is cultivated as an ornamental plant, but it should be kept away from children's activity areas and warning signs should be set up. Overall, Strophanthus divaricatus is a toxic plant with pronounced toxicity and both medicinal value and risk. Only by learning to identify it correctly and handle it cautiously can accidents such as poisoning from accidental ingestion be effectively avoided.
