Choose between the Green Dragon or Golden Dragon tincture methods.
For the Green Dragon method: place the decarboxylated cannabis flower at the bottom of a pint-sized mason jar.
Pour the alcohol over the cannabis. You only need to add enough alcohol to cover the plant matter completely*. Screw the cap tightly and shake gently.
Place the mason jar in a cool, dark location like a cupboard or closet and leave to sit for 24-hours or more, as desired.
After your desired soak time, strain the cannabis tincture through a coffee filter or filter into a clean mason jar, separating the plant matter from the alcohol.
Place the mason jar in the mini-crockpot. Carefully pour water into the crockpot but around the jar, creating a water bath. Turn the mini-crock pot on warm and allow the water to heat up.
Make sure you do not have the lid on the jar, as this will slow down the evaporation process. Additionally, I recommend doing this in a room with good ventilation to keep the windows open and airflow moving.
The time it takes to evaporate all of the alcohol will be dependent on the starting volume of the tincture. For example, 1 cup of tincture will take approximately 4-5 hours to evaporate down into FECO. More tincture will take longer, and less will be shorter.
The alcohol will evaporate off during the cooking process, reducing the volume and leaving behind a thick, black, sticky substance. This black oil is your medicine.
If this black oil gets too sticky or hard to work with, add a few drops of alcohol or carrier oil to the jar and mix well to create a more viscous oil.
Store your FECO in a glass syringe, capsule, or another airtight glass container. Store in a cool, dark place like a medicine cabinet.
You do not need to use the full 14 grams of cannabis called for in this recipe. You can use as much or as little cannabis as you want. Just know that your yield will be very small, as little as 1mL.
*You do not need to use the full 8 ounces of alcohol, you just need enough to cover all of the cannabis in the container you are using. Anything more is a waste.
*How long to soak? I’ve seen traditional, long-soak tinctures steep anywhere between a few hours to up to 6 months, or longer, in some cases. Soaking your plant material for longer will slightlyincrease the potency, but will also increase the amount of chlorophyll and plant matter in your final infusion.
