Bill, I have been making Concentrated Cannabis Oil (RSO) since 2012 using Everclear or other 190 proof alcohol. I don't like calling it RSO due to the Naphtha he used to make his oil, he has since began recommending 190 proof alcohol.
Have a friend who in 2008 was diagnosed with bladder cancer and did Chemo and Radiation and they said he was in remission. In less than a year the cancer returned and he went through another round of Chemo and Rad. and they said he was in remission. Eight months later the cancer returned and the Dr's. gave him 6 to 8 months to live. He decided to try CCO. At that time Oregon did not require you to be a resident to get a Med Card so he took his records and went to a clinic in Portland, got his card and went to a dispensary and purchased a large quantity of CCO and got back on the plane and came back to Texas. He used the Budwic protocol,
Budwig Diet, when he completed the protocol he went back to his oncologists and had a MRI. It came back showing no cancer at all. He began doing a daily dose of 200 mg CCO a day. He was cancer free till earlier this year when the cancer returned and had spread through out his body, he passed away in early Sept. of this year @ 75, but he was cancer free for around 14 years.
He was my inspiration! In 2011 my prostate numbers went out the roof, Dr's wanted to monitor me for a year to see where it led. I ordered 125 grams from the guy who made Mikes oil in Oregon, did 110 grams in 90 days and began doing 200 mg every night before bed. I went back to my dr. after 6 months and my numbers had fallen to just below the high end number where it should be. I now make my own CCO and still take 200 mg a night. I still have BPH but my numbers are stable and my Dr. says if I believe in CCO continue taking it as he sees no ill effect. I sleep better, and it seems to help my blood pressure.
I use a distiller to make my oil and use 1/2 to one pound of buds. The return varies, on one pound i usually get 60 to 70 grams of pure CCO, my largest return was 93 grams. It normally takes 6 to8 liters of 190 proof and I mix either coconut or avocado oil at a 7/1 ratio. No longer put it in caps, just in a dropper bottle.
Will be happy to share my knowledge about making CCO if your interested.
