Pontederia Cordata

In the Colombian region of the Amazon, this plant

is known as amarron borrachero ("hazelwort inebriator").

It is used as an ayahuasca additive but

may also possibly be used alone for psychoactive

purposes (Schultes 1972, 141*). The plant is used

ethnomedicinally to treat facial paralysis (Schultes

1981, 5*). There is also a North American variety:

Pontederia cordata 1. var. lancifolia.
