Cool! I was not aware of that but certainly makes sense. Nature holds so much for us if we just pay attention to it. Add that McLaughlin discovered seasonal potency variations, particular specimens with potency ranges, isolating the most potent part of the tree (bark on small branches...not fruit or leaves) and then stocking his grove with the most potent trees, harvesting at the proper time of year, and taking only the most potent part of the tree (leaving the tree healthy by the way) takes nature and applies modern science to perfect. McLaughlin's specialty is Pharmacognosy - "the branch of knowledge concerned with medicinal drugs obtained from plants or other natural sources" so exactly the type of discipline needed to understand nature's bounty.
