Dear Fellow Investigators & Faithful Companion Igor:
While I am, as yet, unable to offer any first hand Eboka information, I just may be able to contribute something worthwhile to this particular topic.
My current research into curing my own anxiety and depression has led me to experiment with chrysin, a naturally occurring flavone closely related to quercetin. Like quercetin, chrysin is an antioxidant. Unlike quercetin, it is an aromatase inhibitor and is used by body builders to limit the conversion of testosterone to estrogens. Also unique is its ability to act as a partial agonist of the benzodiazepene receptors like valium. Unlike valium, however, it does not cause respiratory depression and drowsiness.
I have been using it as an anxiolytic with good results.
Here's the interesting part wrt entheogenics: it is also an MAOI.
Hence, it may be able to prevent the deactivation of DMT in the gut, as do the harmala alkaloids. It may also be able to prolong the effects of DMT in neural tissue, as do the harmala alkaloids.
Given chrysin's anxiolytic action, it could just be the most fantastically colorful and peaceful experience ever...

Or not.

Due to its one significant drawback, poor absorption in the gut, I plan to orally ingest 2 g of chrysin in the morning, to build up a significant serum level. Then, several hours later, I plan to ingest another 2 g of chrysin along with an extract of M. tenuiflora that contains approximately 100 mg of actives.
My lab notes will probably appear here Sunday or Monday.
Let us now hasten to the tower laboratory, mine trusty Igor! (Bwa-ha-ha!)
