I have no idea who does what and which way things are manufactured unless I dowse each and every item.
I can tell you from past experience that an Allergy pill which had a fraction of its parts wrongly charged caused many Liver cancers. While the same thing produced by nature and if properly handled negative ionized would make it through the liver without any issue at all.
Everything a plant digests for us is negative ionized, every negative ion a healthy non drugged up cow digests adds negative ions to the raw milk. Nearly every process after that has the possibility to change that.
Like that Finnish Sauna article from a few years ago. We can build saunas and sauna ovens and insulate but you can NOT duplicate the negative ion charge you get in a Finnish Sauna burning wood..one experience does NOT equal the OTHER...
