This tea is good for morning, noon or night! However, the more sweet fern you put in the more it feels like a night time tea, to wind you down, and the more sumac you put in the more energized it makes you feel! For a whole pot, I grind up one small chunk of chaga about as big as your thumb nail (either witha coffee grinder, or smoosh it up with a nut cracker), two long dried sweet fern leaves, and about a tea spoon of sumac seeds. The sumac seeds are separated from the actual sumac "spice" that we use for cooking, but the seeds are great for making teas. Enjoy!
