Thanks!

As for spagyric extraction, it's just a matter of little experimentation. I haven't fully thought it through yet. What I've figured out so far is that it would have to be an eco-friendly extraction tek. No naphtha and no lye. Instead it would have to involve ethanol since that is the generally accepted Alkahest of the plant kingdom. The ethanol would also have to be prepared according to the art, which means low-heat distillation of unburnt wine. Also, taking the plant material (Prima Materia) straight out of nature would be a big plus.

I found a thread where a Nexus member was doing an extraction using ethanol and white vinegar. That is definitely something I could work with: Extracting DMT with ethanol, vinegar and sodium carbonate - Eco friendly extraction teks - Welcome to the DMT-Nexus

As for the actual spagyric process I'm not quite sure. I'd have to do some normal extractions to begin with to see how one would go about it from an alchemical perspective.
