When doing research on interactions with harmala alkaloids DO NOT LOOK AT OLD MAOI RESEARCH, look at new RIMA research. Harmala alkaloids are RIMAs, not full blown MAOI compounds. They are much safer. This is why ayahuasca often contains things forbidden to use with MAOI compounds, because ayahuasca only contains RIMAs.
RIMAs are Reversible Inhibitors of MAO subtype A. Most other MAOI compounds are not RIMAs, they are not reversible, they permanently destroy MAO and are many times more dangerous. For example, eating aged cheese high in tyramine is relatively safe when using RIMAs, but can kill you if you’re using normal MAOI compounds.
