Muktaphala
The muktaphala or muktā-phala is a plant, also known as the cobra lily, of the genus Arisaema. It is also known as the 'liberating fruit' and the 'pearl fruit.
Somewhat similar in appearance to a husked maize ear, the berry is strongly psychoactive, and is highly favored in Nepal as a means of creating visionary trips. The rhizome of Arisaema utile is used against cancer, possessing "anti-proliferative activity ... to prevent cancer".
