Akava - no worries. For me the "potential" cons do not outweigh the pros from a scientific basis. I have talked to some of the leading kava scientists surrounding the controversy of flavokawain b and they pointed out that even some water based extracts *given a poor starting material* had high levels of flavokawain...ie. New Caledonia studies and hepatotoxicity cases with water only. Thus, if starting material is bad (whether ethanol or water extract) you still get the flavokawain b.
I am not against CO2 extract by any means at all (as I use to use it for my boutique drink that I had in stores) but it is rather expensive and would increase the cost substantially. One potential cons is that whoever is extracting can tweek and essentially (and artificially) make a chemotype that does not exist in nature. You can take a very bad / cheap strain and make it seemingly good by extracting desired levels of lactone - do I dare say GMO to an extent? Also, IMHO there are not enough studies out there on CO2 to prove that it is in fact 100% safe. I know some people who do a tremendous job and really understand CO2 for kava but likewise, there might be the potential for people to take leaves and stems (and all the bad stuff) extract kavalactones with CO2 and inherently call it the best thing ever.
With that said, I hope to one day move to an all-natural formula with a CO2 extract; thus I can truly have the *exact same* profile from year to year and starting with the best kava root is key for a great product. After all, kava is from nature and there are different natural variances that are seasonal. Hope this makes sense
