I have also read, just now, that it is best not to use the red cedar berries *unless you are going to eat within half an hour*, they lower the blood Sugar that much. For someone with hypoglycemia, this would seem relevant. Myself, I'm not altogther clear on the fine distinctions between berries: juniper and cedar: number of stones is one marker.
I like to add juniper berries to kombucha, to give it a second steeping. Quite delicious, a bit resin-y. Feels very good in the humid summer especially, when one seems to retain water.
