You’d be wrong on that I’m afraid:

The Black and White Minstrel Show is a British light entertainment show on BBC prime-time television that ran from 1958 to 1978. The weekly variety show presented traditional American minstrel and country songs, as well as show tunes and music hall numbers, lavish costuming and often with cast members in blackface.

I wonder if it would be possible to find an option at an actual university that still aligns with her interests. Thinking more along witchy lines than medical lines, would something like anthropology interest her? There’s specialisms like ethnomedicine which would explore traditional/herbal medicine from a more academic perspective.
