I suspect it would have a greater antagonist (blocking effect) if used before a trip vs during. However nothing anecdotal has been reported on nexus yet.
It is a histamine and would be a safe mix in ayahusca but as stated it may dampen the trip. Ayahusca won't cause serotonin syndrome unless mixed with say a pharmaceutical MAOI then there would be a greater risk. RIMAs like harmala is alot safer. The risk of serotonin syndrome is very very low with ayahusca itself.
