Susan, I know you will be cautious when trying anything new. Like you said, in moderation.
Have you had a chem panel lately to check for kidney or liver function? That would be my main concern with this plant.

I do think it can be very dangerous to use a plant yourself, especially for internal use. I'm sorry but we are not herbalists or scientists and plants are not benign. Please be careful.
