This first study is from 2012 and they explain how they made their extract from the entire plant. The second study is from 1862 where they explain how they essentially made a tea from the root of the plant. From these two studies, I believe you need to use at least the entire plant. Roots included especially because according to the older study, the Micmac Indians said the compound is found in the roots of the plant. In the 2012 study they used the entire plant.
I searched around and see tons of stuff on how to grow, but find nothing so far on how to render the plant into a form that can be taken as medicine.
Does one just eat the leaves, or boil them to make a tee, or ..................
You find anything on this?
