To my understanding, rue isn't particularly a great source of THH, but high in harmine and harmaline and 'the bark' is usually your DMT source. I'm the worst one here probably to ask about extractions as I'm fundamentally opposed to them (always willing to change my perspectives though), but the 30x extract is cappi that has been boiled down to a concentrate and would likely still have a substantial proportion of THH in there, if it's legit as THH is fairly stable. Thought about getting some of that myself at one point, curious as to it's efficacy compared to raw vine materials.
