Aboga Root /Nigeria

Hello Readers.I was watching on tv this evening a show called, "tribal", and this man was taken to a village that had headhunters and believed in Cannablism.
The tribe gave the visitor a root called Aboga Root, believed to see spirts, and also has been known to help herion addicts, depression, and other problems....... Does anyone know where i can do more study's of this root? I'm unsure of the correct spelling, but its pronounced:
Ah-boe-gah Root....... and it's known to create hallucinations, and used somewhere in Nigera?
Anymore information pertaining to this would be greatly appreciated.
Thank you.
