I agree that when combining it is hard to say which herb is not effective. Actually, we should not look at it as separate herbs, but rather, we should look at the combination as one.

I've experimented with Fenugreek seeds, bittermelon pills, banaba leaf extract pills and one other of which the nam eludes me at the moment. I'd try the bittermelon again, but the others I'm pretty sure aren't that effective for me.

There is something about the gymnema that keeps me using it. I feel it is the safest of all herbs. I find it works well in combination with my vitamin and mineral supplements.

My FBGs' haven't been so good lately. My average BG is up a bit, but my pp meals are doing great so far.

My culprit is not adhering to my diet as well as I should. My carbs need to be cut back and I need to quit experimenting with how much I can get away with. A year ago, I would never have eaten the way I'm eating now. What changed in my head is still a mystery to me....
