For sure, rue will catalyze chacruna. Rue is a potent RIMA. Rue seeds may be consumed, ground, or brewed, @3-4g works for most persons. RIMA, then ingest your chacruna tea. Chacruna leaves can be simmered in slight acidic water for @one hour. Remember, filter, THEN, reduce. Always, filter, then reduce...any alkaloid brew. With anahuasca, RIMA, then DMT carrier.
The issue with chacruna is, widely variable potency. "Good", Hawaiian leaf will render dreams with @15-20g. More available, "Peruvian" leaf may take double that weight for a single dose.
Caapi is "ayahuasca" for a reason. It brings psycoactivity to the brew. It is however not ergonomic, requiring large weight, @50-150g for adequate RIMA, unextracted. Currently, quality caapi extracts are generally easy to have. These work well, with WAY much less hassle.
Enterally ingested DMT brews can be superb. Facility and ergonomicity are, for the "average guy", important.
