Researchers who promoted an alleged cult and showcased its bizarre healing claims have ensnared the University of Queensland (UQ) in a large-scale academic misconduct probe.

The University of Queensland and two international medical journals are investigating alleged ethical violations in research around Universal Medicine (UM), an organisation based in Lismore in New South Wales which touts the healing powers of various unproven treatments.

An investigation conducted by the ABC reveals that three members of UQ's faculty of medicine have publicly advocated for the controversial group.
