    Summary dose.wiki Erowid TripSit PsychonautWiki

    Ayahuasca is a brew combining DMT-containing plants with MAOI-containing plants, requiring both components to produce psychoactive effects. Traditional brews vary widely in potency depending on plant sources, preparation methods, and regional practices. The purgative effects (nausea, vomiting, diarrhea) are considered an integral part of the traditional experience and can be intense.

    Effects Erowid Bluelight

    Aggregated from 112 single-substance Erowid and 25 Bluelight experience reports; 29 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Also reported in combinations. In the 29 Ayahuasca reports where another drug was taken too, 1 (3.4%) mentions hospital, emergency services or an overdose, 0 (0.0%) a seizure and 2 (6.9%) psychosis. In the 112 single-substance reports: 4.5%, 2.7% and 3.6%. These are not in the figures above: they cannot be put down to Ayahuasca alone, and a mention is not always something that happened to the writer.

    Combinations TripSit

    Cross-Check Ayahuasca with another substance

    Ayahuasca's harmala alkaloids are MAOIs, so these are TripSit's MAOI interactions, plus TripSit's DMT entry on lithium. TripSit's ayahuasca factsheet says to avoid anything contraindicated with MAOIs, particularly SSRIs, MDxx compounds such as MDMA, and amphetamines.

    The real work was always in the integration, but I didn’t expect it to go that far neutral r/Ayahuasca ▲18 21 comments

    From the beginning, I knew that the real work with ayahuasca wasn’t the ceremony itself, but what comes after. The visions and intensity matter, of course, but they felt like openings, not conclusions. What I didn’t expect was how far that integration process would take me.
