Is all plain Salvia Divinorum leaf created equal?

[nEone]

So - ignoring extracts for a moment - SWIM wants to know, in general - is all plain Salvia leaf created equal?

There are different strains, SWIM has seen: Blosser, Hoffman/Wasson, etc. but ultimately, is there much difference?

And, if SWIY was going to buy a bulk supply of Salvia in anticipation of future legislation - would SWIY buy plain dry leaf, or an extract?

SWIM missed the GBL boat and is seriously annoyed with himself for scoffing at gallon jars in health food stores, only to turn around one day to find the supply completely cut off. He doesn't want the same thing to happen with Salvia, so he's hoping to stock up. SWIM knows that properly dried plain leaf will last for a long time with no appreciable change in quality, if stored right. Do extracts follow the same rules, or does the process of extraction make the product less stable? SWIM doesn't do Sally all that often, he just wants to have the ABILITY to whenever he damn well pleases - be that in a month, or in two years.
