Is there any
likely impurity that will be toxic at that level?
How much will you be dosing, how often and for how long?
What cumulative poisons are likely to present a problem within your planned dosing regimen?
What about everything else that you eat, drink and breathe?

“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
