A couple of pointers:
2.2 No discussion on selling, buying, sourcing, acquiring, pricing, trading, receiving, distributing, mentioning pending deliveries or smuggling of drugs2.14 Only talk about sources for live plants and seedsIt would be useful to know what extraction solvent was used for producing the material you have. Is it likely to be harmala alkaloid freebase or is it a salt form such as the hydrochloride or acetate?
Here is the
Harmalas subforum, where you can read about harmala extraction techniques.
You could try dissolving your extract in 95% ethanol first. If that doesn't work try distilled water, then try water slightly acidified with acetic acid.
If it dissolves in ethanol you can put that onto your changa herb and allow to evaporate. The trouble is, you have no idea what the extract really is nor how strong it is. For changa you could use caapi leaf instead, or use Syrian rue seed to produce your own extract. This would remove an unsettling element of uncertainty.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
