Lots of controversy on the subject, but I think the answer is that several more readily available solvents will work, and you use the best safe one that you can get your hands on.
All should be taken out to below levels of concern afterwards anyway, regardless of what they are. Most not only have to be purged below levels of health concern, but below our more sensitive senses of taste and smell
We extract most of our cancer donations using butane, because it is effective and inexpensive if you recycle and we winterizing with ethanol because it is food grade and readily available here.
As I understand it, to be effective, we need to ingest enough cannabinoids over a 90 day period, to restore natural apoptosis to the tumor cells and starve them of additional blood supply for growth. How they were extracted, is of less importance than their presence.
Rick demonstrates using Naphtha and mentions using Iso in the video I watched, and his reported success speaks for itself, but I am troubled by using a solvent that only has a specified boiling point, instead of a specified content. If you start pulling up MSDS sheets for Light Naphtha, you will soon see that different manufacturers include different ingredients besides just Pentane and Hexane, some of them insalubrious.
Non polar simple alkane solvents like some of the ingredients in Light Naphtha work very well for the process, which is why we use simple alkanes n-Butane and n-Hexane for extraction and alchemy.
We use Ethanol for winterizing, for the reason mentioned above, and because it not only does a better job than Isopropyl for that purpose, but it has better patient acceptance when used or oral consumption.
If I could get nothing but Iso, I would most certainly extract with Iso before I would let a patient die, because I know that at the residual levels left in the oil, the Isopropyl isn't an issue, despite it being toxic at higher levels and causing auditory nerve damage.
I also know of patients experiencing miraculous results on Iso extracted oils by others, so that leads me to a bigger issue, and that is that the patient needs to be able to take enough oil to be effective.
A bigger issue for us, has been that if the THC is too high in relationship to the CBD and CBN, they will never be able to take enough to achieve the desired results without discobobulation.
We have made great inroads in that regard, by using high CBD strains like Cannatonic, and Hawaiian Bubble Gift. Heavy doses just puts them to sleep, instead of couch locking them with a racing mind.
