Another update:
Age of S. divinorum leaf makes little difference for the “Crude” tek. I did a run with 500mg PC and 4g powder made from ~18+ months old salvia shake (was lost in my closet), and it was shockingly close in potency. I’m now letting some fine powder rest to see if will be impacted more by oxidization than the shake was.
The “Pharma” tek is likely going to require a full spectrum extraction (50% water + 50% solvent). I did a ton of research over the past two days, and my working theory is that Salvia divinorum contains inhibitors. Other Salvia spp. have quercetin, luteolin, rosmaric acid, carnosic acid—essentially an array of CES1 inhibitors (CES1 is thought to metabolize salvinorin A -> salvinorin B) and PLA2 inhibitors (PLA2 metabolizes phosphatidylcholine and compromises micellar protection). There seems to be a really interesting entourage effect happening with the crude tek, and this might even include the bitter leaf powder triggering bile release (more micelle formation). I’m wondering if salvinorin B could even be inhibiting PLA2—there’s little known about S. divinorum / salvinorins other than salvinorin A being a potent KOR agonist.
Some polyphenols / acids are hydrophilic, meaning they wouldn’t make it into the purified salvinorin A extracts—this could be why myself and others (possibly including Daniel Siebert) have struggled with orally administered acetone extractions.
At the moment, I am going back to basics: evaporating a tray of 10g full-spectrum extract with 1g cornstarch, dividing this into titrated doses, and then taking each dose with 500mg PC until I approach threshold.
If this works, then I will evaporate directly with dissolved PC before evaporating; essentially, I plan on making an active, green, waxy product. This wax (lipid matrix? Delivery system?) will then be divided and taken in both warm water / capsules to compare effectiveness.
Aside from all this, I’m wondering if the unique smell associated with Salvia divinorum might give some clues as to what other plants contain similar compounds (flavonoids and such). Finding something that inhibits CES1 and PLA2—that can also be purified—might help with creating a purer “Pharma” capsule. Anyone ever notice a similar smell coming from other plants?
