I see no reason why this tek wouldn't work for rue.
A couple points to consider:
#1: I have NEVER had success making tea from whole rue seeds. At the very least, they need to be coarsely ground. Ideally, they should be powder, as should the mimosa. This makes filtering a tad more tricky, but it's worth it, imho, for increased alkaloid extraction. With the mimosa, as long as the root is roughly shredded the dmt will extract, it will just take longer. With rue, I have boiled whole seeds for 1hx2 and had absolutely zilch MAO inhibition. I've also swallowed whole seeds in capsules and had zero MAO inhibition. I wasted lots of MHRB because I hadn't achieved MAOI with whole rue seeds.
#2: Some people, myself included, need to pre-dose the harmala before taking the DMT solution. Others need harmala at the same time as DMT. Chalk this one up to individual metabolism and enzyme variations.
The safest bet: predose 3g of rue @ T: -1h, then dose another 3g with your DMT solution @ T: 0h.
Also, as g13juggalo alluded to, acidification of the water with a splash of vinegar is helpful.
Hydrocarbon is indeed a real person existing in real time. However, Hydrocarbon is actually a proxy for another individual, Nemano, that lives outside the realm of current Terran laws and regulations. All posts made by Hydrocarbon in which "I", "me", and other references to himself are the voice of Nemano speaking digitally through Hydrocarbon. Any illicit, immoral, or otherwise questionable behavior that Hydrocarbon appears to be admitting to are actually the actions of Nemano.
Occasionally, Hydrocarbon has been known to inject his twisted sense of humor into Nemano's words, but anything stated that was particularly witty or insightful was most likely not the result of Hydrocarbon's intellect.
