Thank you for sharing your knowledge Gray Wolf.
What do you start with I was checking out your thread on the holy anointing oil it is very in depth and very informative.
How is 91% iso comparatively to bho and other choices?
I have to agree on the RSO using Naptha as the solvent to produce with. Hard for me to imagine ingesting that, but at least seems to work for some folks that have tried it with success. Rick did state that he was trying to make it easy for anyone to make.
I tend to think that the less harmful ingredients will lead to a safer product for sure!
You can do an effective extraction job with a variety of solvents.
Because of the infighting about which process is best, I split up a sample of Blue Dream and extracted discrete lots with Naphtha, Hexane, n-Butane, 95.6% EtOH, and 99% Iso.
I then ran them through our gas chromatograph and the cannabinoid profiles were all within the central scatter of one another and within the error of my GC process.
I use BHO and QWET, because butane is easiest to purge, with the least monoterpene loss, and food grade EtOH purges aren't as critical as Iso, nor does the thought alarm our patients as much.
Rick did and said a lot of things right, and some I disagree with.
He did state that he picked varnish and paint makers Naphtha and Isopropyl, because they were readily available to everyone, and his rice cooker process, cause anyone could do it, and I agree that when your back is against the wall, that you do what you must do.
When there are choices, I prefer to err on the side of caution, especially when some of the choices are not just toxic, but carcinogens.
Rick's observation that the carcinogens are mixed with a powerful anti cancer cannabis cocktail, is true, but the powerful mix without the carcinogen would ostensibly be preferable, given the choice.
His rice cooker purge also leaves residual hydrocarbons above the FDA pharma standards for even class three solvents, and his argument that the residual hydrocarbons tie up the liver processing them, so the cannabinoids are in our system longer, is no doubt also true.
We have however elected to use coconut oil for that same purpose, given the choice.
Rick brought much light on the subject and ran with the ball during tough times, so we owe him a debt of gratitude, whether we buy into all of his ideas or not.
