Question on Pot Brownie Directions

This info is from a recipe online:

"Your goal is to aim for less than a simmer. Finding the optimal temperature on your cook top essential. Too low a temperature will extract very little THC from the ground shake. Too high a temperature will boil and burn the oil. Since all burners are unique, start out on a medium-low temperature and use good judgment."

On the part that says "too low a temperature will extract very little THC from the ground shake," does that mean that you are wasting the weed? Or will you still consume that THC that you "did not extract" when you add the whole mix to the brownies and eat it?
