context_page_description: Morning glory is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:
  Argyreia
  Astripomoea
  Calystegia
  Convolvulus
  Ipomoea
  Lepistemon
  Merremia
  Operculina
  Rivea
  Stictocardia
context_section_description: Morning glory was first known in China for its medicinal uses, due to the laxative properties of its seeds.
  Ancient Mesoamerican civilizations used the morning glory species Ipomoea alba to convert the latex from the Castilla elastica tree and also the guayule plant to produce bouncing rubber balls. The sulfur in the morning glory's juice served to vulcanize the rubber, a process predating Charles Goodyear's discovery by at least 3,000 years. Aztec priests in Mexico were also known to use the plant's hallucinogenic properties (see Rivea corymbosa).
