英语词汇mother-in-law plant的起源、历史背景-英语词源词典

词汇	mother-in-law plant
词源	mother-in-law plant. A common name for Dieffenbachia seguline, which itself honors 19th-century German botanist J. F. Diefenbach. Dieffenbachia is called the “mother-in-law plant” and “dumbcane” because an irritating enzyme in the leaves of this houseplant causes swelling of the tongue and temporary speechlessness should they be chewed. But no one should wish Dieffenbachia poisoning on a mother-in-law or anybody else; it is a dangerous, painful condition requiring prompt medical care.
