The harmala should be, its Syrian Rue, which contains an MAOI and has been used in recent decades for creating ahistorical version of Ayahuasca by combining it with either a DMT containing plant or synthetic/extracted DMT. I think access to the actual plants used traditionally for Ayahuasca is more common so probably Syrian Rue has likely become less used for that now.
