Argyreia nervosa

Argyreia nervosa is a perennial climbing vine 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 and medicinal value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are A. n. var. nervosa described here, and A. n. var. speciosa, which are used in Ayurvedic medicine for their medicinal value.

Argyreia nervosa seeds contain various ergoline alkaloids such as ergine. A study reported stereoisomers of ergine to be found in the seeds at a concentration of 0.325% of dry weight. A more recent study reported presence of ergometrine, lysergol, lysergic acid and other alkaloids that contribute to its pharmacological effects.
