To be honest, Deb, most of my Stevia is commercialy sold (powder, liquid & tablets). I have just one plant, but when Fall comes, I cut the stems back leaving just some 2". The dried leaves are easily made powder, that you can even use for cakes.
I really do not know if both or just one of them (stevia & ginger) work for me - I just know the pain became bearable when I started consuming these two products (almost simultaneously).
I would love to hear they work for you as well!
