this is a somewhat ancient tea that must be smelled/tasted to be believed!! i was stunned by its depth and smokiness when i first had it! i have only ever had it loose leaf, maybe there are packs available, but dw! loose leaf is super easy! just put the leaves in a little mesh ball (like the pic i've attached, there are variations of this product like with clamp handles, u can find these at the dollar store) and steep it!! im not technical w it at all, i just take it out of the water after ~5mins, and it is delicious and energizing. this is a caffeinated tea
