Bill I’ve been doing ethanol extractions out of my chest freezer for about a decade. When I started I would do fico extractions but at the time I thought all of the chlorophyll and plant waxes were causing some stomach issues. I was also frequently overdosing myself. I decided to do as clean of an extraction as I could.
I use all bud in my extractions. First I let it dry completely to inhibit chlorophyll transfer. I’ll break up the buds using my snippers and put 1 oz in a mason jar, I usually do 1/4 lbs an extraction. Freeze for at least a day or few. Ethanol in freezer also.
Pour enough ethanol to cover weed and shake. Let sit 15 min. Strain out ethanol with big Bunn coffee filter inside metal mesh strainer sitting on a measuring pitcher.
Then I wash same oz again, let set 15 mins.
After 2nd wash sits I dump weed and alcohol into coffee filter and let it drain a few mins. Then I squeeze the filter into measuring pitcher.
I filter two more times thru coffee filters in cups, I also let the tincture sit out in the sun for an hour to kill what chlorophyll is left. It turns golden from green. Then I run the tincture through my AirStill.
I buy 00 veg caps that hold .95 ml.
So if I have 18 grams concentrate and want to make 5 caps per gram, that’s 90 caps.
90 x .95= 85.5. You have to subtract the amount of concentrate from that. 85.5 - 18 = 67.5. Next step is decarb concentrate, I do 80 mins at 240f. Then freeze overnight and decarb 60 more mins. After decarb add 67 ml coconut oil and a drop or two of sunflower lectin. I like to put it in squeeze bottles which makes it easy to fill caps.
I take my caps for insomnia so not sure about all the variables involved in making the meds for your friend. I have made my caps with sativas before and they kept me up all night. Good luck, I hope your friend finds relief from your efforts.
