If I had to give this a number based on what it should taste like it would pretty low. Giving it a number the way I make it, well it’s not possible to give a tea a negative number. I’m taking this for insomnia because my doctor’s prescriptions don’t work anymore and I haven’t been able to convince her to prescribe something else. While I do think it’s time I found a new doctor I’m hoping this works for tonight. I brewed this with 6 tsp leaf, 4 tsp valerian root, and four eye droppers full of valerian root extract. I’m hoping it helps me sleep. It tastes positively vile even with added maple syrup and agave nectar.
