Olive oil extract update...

I wanted to edit the original post above, but it seems that that’s not possible here, so here is an update to the update.
It seems others are curios about this method, and I just realized I haven’t yet posted exactly how I did it, so here it goes:

First, I used freshly harvested MJ, straight off the tree. Reason being is that after only a week of drying over 30% of the terpenes are lost. And since with olive oil its possible to retain everything of medicinal value regardless of water content, fresh is the way to go.

The ratio I used is 400grams MJ to one liter of oil. That’s about 100grams dry going by what I dried for personal use. Any more bud than that just won’t fit. As I put the bud into the oil I used an immersion blender to grind it down and make space; this is the only way to make so much fresh bud fit into the oil.

Second, cooking! The temperature I used was 105 degrees Celsius for 2 hours. I found this study which basically confirms other findings on the net. And considering that some terpenes are volatile already at 119 degrees, 105 looked perfect.

Cooking was done via double boiler method. Water in the first pot obviously won’t get the temp up enough, so I used ordinary sunflower oil to bring up the temp. I used a cooking thermometer to check temps and mix every 5 minutes. Obviously I had temperature fluctuations but on average I was close to what I needed.
The main thing to keep in mind here is that the fresh bud has lots of water content and so it takes a while to get up to temp as the water evaporates. Main thing was to use a low flame and just wait out the evaporation. When the temp went over 100 degrees I started counting down. Here you just have to find and average for temperature and time .. you kinda get a feel for it. 105 for 2hours is the baseline though.

Third, separation. After a few methods, I found one that works best for me. The next day, once the oil is cooled, I put it into my vita-mix, oil and bud, all in. I then proceed to mix it completely, after which I pour it into a glass pitcher. Over the next few days the really finely ground bud sits on the bottom, and the oil gets poured into.. well into whatever. The bud that’s left at the bottom is then scooped up, thrown into some fabric and into a French coffee press for a final squeeze. This worked best for me.
I tried pressing the bud straight out of the pot, but this method above was simpler, and more effective. Very very little oil gets thrown out. I’m sure no more cannabinoids are lost this way than what gets thrown out with a solvent extract.

Fourth, consumption! 1.5ml of this stuff has me going all day. The first time I tried it, I took 5ml, and didn’t come down in over 2 days. Best time to use it is shortly after a meal for maximum absorption, as shown in a few studies, including one by GW Pharmaceuticals for their product Sativex. As a topical its also very effective. My mother in law was using almost 15ml per day with max tolerance.. others are using much less naturally for milder conditions. My father for example uses 4ml at night, and doesn't wake up to go pee 4-5 times as usual because of his prostate.

All in all, this is a VERY complete method of extraction and decarboxylation. I also used this method with much less heat for a THCA oil which is quite different than the THC version.. although this method required many hours for evaporation of the water.

Any questions??
