I can tell you that it tastes NASTY and smells bad, too. I have the powder form. I just made a tea of it yesterday. I don't know if it helps or not as tea is not the best way to go for Goat's Rue. Yucky, yucky, yucky... and I am not that picky.
Dosage on the bag says something like 1/4 to 1/2 tsp in a cup of hot water 2x/day.
Best wishes!
