I think I gathered that one from "The Ibogaine Story" but I can't check because my hard copy is in general circulation with my friends and the online version seems to be missing the miscellanious tidbits it lifted from other sources. If I remember correctly it referred to both Mohammed and his daughter being instructed to consume harmel but it may have been refered to by a number of synonyms. While I was looking around I found this which might an interesting lead:
