The commercial extracts used sublingually are debated. Sme claimed it worked, others not. Some claim it worked with a minimum work. exemple the Bublegum tek ( sublingual tek ), the pull with acetone, filter, evap, mix with saliva, and IR tek.
Many teks.
However what you gathered as information are exactly what is listed in sage wisdom site from Daniel Siebert.
Am I right in assuming you got all those informations on this website ( sage wisdom dot com ) ?
SLavinorin A is not soluble in water but we see we even have salvia tea tek..
what I would do is pull with acetone a part, filter and evap and mix with with some everclear or 90° min; ethanol whihc also pulle d previosuly some dried leaves.
and combine those extract to make a strong tincture but which isn't only salvinorin A.
I had great success long time ago with some tinctures. but other time not at all.
I do'nt like smoeking extract much, but smoking simple dried leaves is better already. Or vaping commercial extracts like in the GVG.
Many things to experiment there. I also saw a tek whihc call for some aspirin at some point. Maybe with glycerin. I shoudl try find it itssomewhere. Some also wer discussing using DMSO as solvent carrier.
Smell like tea n,n spirit !
Toke the toke, and walk the walk !
