I used to make iso hash oil, but I clean it up by winterizing it. When the iso oil is done, I melt it into ever clear 190 or Klean xtract, then freeze it for 3 days, refilter and reduce again. Some of the wax or sediment stays on the glass that was holding the oil in the freezer, and some is caught by the un bleached coffee filters, but you do really get more wax out. And the resulting oil is as clean as can be. And I think safer as well. No more stomach issues that iso causes.
For ingesting we mix high cbd oil with high thc oil. And then make canna caps. A typical dose is 2ml hash oil to 1 fluid ounce of organic coconut oil, and 1/2 tsp of powdered lecithin. Lecithin is an emulsifier and makes oil particles smaller allowing for a more efficient uptake. We mix the oils and lecithin on a coffee warmer and fill size 00 gel caps with pipettes. With the amounts listed we get approx 30-34 caps of a fairly high dosage. This is a strong dose, one ml oil to one fl oz of coconut oil is a lower dose, three of hash oil to one fl oz of coconut oil would be rough for all but canna veterans.
So far we have not tried this on active cancer patients, ( i believe it would work well, remission patients like it, for what thats worth) but it works fairly well for pain and epilepsy.
