I am looking for natural MAOI's besides the beta-Carbolines from B. caapi and P. harmala. The three weak MAOI's St John's Wort, Blackcurrant and Passion Flower is already on my list. Is there any other known MAOI's (both weak and strong)?

Thank you in advance.

I see that Piperine from pepper is a weak MAO-B inhibitor. Would ingesting a MAO-B inhibitor make any difference at all when taking Tryptamines? As far as I know, Phenetylamine is broken down by MAO-B and Serotonin mainly by MAO-A. As Serotonin is a Tryptamine, I suggest that other Tryptamines is handled mainly or solely by MAO-A. In that case, a MAO-B inhibitor would have no or minimal effects. Is this correct?

And, what species of Passion Flower contains the most Harman? It exists around 500 species of Passiflora, and according to Wikipedia not everyone contains Harman.

There are a number of synthetic potent and selective MAOI compounds. I am not sure if they are still available as prescription drugs however.

reversible inhibitors that are selective to MAO-A, so DMT metabolizes from peripheral inhibition in the gut. I've read that some SSRI's have been responsible for potentiating effects, like THH but can't account for the pharmeceutical kind nor would I recommend any of them in combination with MAOIs..

P. Incarnata comes mild, believe alkaloid content is around 2%. Mostly results in slight nausea pending from person to person but I found euphoric concentration at its finest; must be the harmalol.. may also trigger reflex vasoconstriction but this was never really noticeable imo. Entirely safe.

There's plenty other easily obtainable MAOi containing plants to consider, bai ji li, yohimbe..

Yes, I am aware of that, but I would like the MAOI to be from organic sources. In addition, anti depressive drugs of the MAOI class have been replaced by the SSRI's here in my country.

Thank you coz42! P. Incarnata is added to my list. What about the potentially toxic cyanogenic glycocides, are they found in P. Incarnata?

I didn't know Yohimbe contained MAOI, and I have never heard of Bai Ji Li. Thank you again! I do however want to see if I can find MAOI either growing wild here in Norway (like Blackcurrant and St. John's Wort), or purchasable at the supermarket (as Passion Flower, Pepper).

tribulus terrestrius has been somthign that peeps have been exploring and i think its worth working with...
its a common invasive weed and theres tons of it for cheap...
