Argyreia nervosa is a perennial climbing vine that is native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa and the Caribbean. Though it can be invasive, it is often prized for its aesthetic value. Common names include Hawaiian Baby Woodrose, Adhoguda अधोगुडा or Vidhara विधारा, Elephant Creeper and Woolly Morning Glory. There are two botanical varieties: Argyreia nervosa var. nervosa described here, and Argyrea nervosa var. speciosa, a species used in ayurvedic medicine, but with little to no psychoactive value. A. nervosa seeds contain various ergoline alkaloids, such as ergine, which can produce psychedelic effects. Ergine is found in the seeds at a concentration of around 0.3% of dry weight.
