Argyreia cuneata is a perennial climbing shrub which is native to the Indian subcontinent and is related to Argyreia nervosa.
Common names include purple morning glory, mahalungi, and kallana gida.
Argyreia cuneata is a perennial climbing shrub growing from 150–200 cm. Its stems are covered with soft white hair. The leaves are about 6 centimeters long by 2.5 wide with wedge-shaped bases. The flowers are purple and about 5 cm long. The seeds are brown, about 1 cm long, and elliptically shaped.
Like those of Argyreia nervosa, the seeds of A. cuneata contain various ergoline alkaloids such as chanoclavines and lysergic acid amides.[1] [2]
The leaves are traditionally used for treatment of diabetes.[3]
