I'm curious about the alcohol method.
I make homemade tinctures (which is taking dried or fresh herbs, plants and/or leaves and soaking them in Vodka/rum/gin) and storing in a dark cupboard for anywhere from 2-6 weeks; depending on which herb/etc you are using.

So why is it recommended to put one with cannabis in the freezer?
Do the freezing temperatures keep some kind of potency level higher than room temperature?
