I'm very curious to try Syrian Rue. Lately I've been taking the time to connect with Nicotiana rustica (which I've bought as Mapacho in Peru and as Aztec tobacco in Mexico) - one of the seed sites describes this particular tobacco as having some MAOI content. At one point I was eating a small amount of this shredded tobacco and noticing effects much more clearly than what I get from smoking (but not inhaling) and I've had it as a tea with another plant at a Mapacho retreat. I'm looking forward to putting this MAOI claim to the test by following some of this tobacco with some mushrooms.
On the topic of using the effects of these kinds of plants to explore trauma, while I was at an Ayahuasca retreat not too long ago I read The Body Keeps the Score which helped me understand, recognise and start to deal with my own trauma - which had been coming up as a persistent but immovable ceremonial block for quite a few months.
