Quick Cold Wash Method
Place a bottle of 95% ethanol in the freezer over night. Chop the raw plant material up and place it in an empty bottle no more then 3/4 full and put that in the freezer too with the lid off. The next day pour the freezing cold ethanol into the bottle of frozen herb until covered by 1/4 to a 1/3 over the top of the herb, put the lid on tight and shake for three minutes then stop.
Remove the lid and strain. Rinse with a small amount of freezing cold ethanol to flush the last bit out. Next, pour the ethanol herbal solution through a coffee paper filter. The result is a red/yellow off clear full strength tincture of cannabis, with little to no chlorophyll’s to speak of and all three medicinal fractions fully rinsed from the herb.
Evaporate the ethanol out. Use a fan in a well ventilated area to make a cannabinolic acid extract e.g. THCa and CBDa or activated extracts THC and CBD by applying gentle heat, below 100 degrees by using a rice cooker or steamer in a well ventilated area. The dry oil is yellow-clear, and highly potent.
