Grind buds in coffee grinder or food processor to a kosher salt consistency and dump into mason jar.
Cover buds with desired amount of high proof alcohol, I like Everclear. (remember potency is variable and ratios for medicine vary by patient) Shake like mad for 3 entire minutes.
Once you're done shakin' it, your buds will have turned from bright green (like the prev pic) to a wilty color as shown on the left here.
Strain tincture through a mesh kitchen strainer. You can use a ladle to press the plant matter to ensure you've removed all your extracted alcohol. Measure your extraction and replace alcohol lost during process to return to your original amount of alcohol for easier dosing. Store in mason jar and use as desired. Enjoy :)
