It is on order so I don't have the bottle in hand, but my instruction sheet written out by the kinesiologist has it listed as Rattlesnake Grass 4X. Perhaps Maya has heard of this before. As with all medications, dosage is critical. A few months ago my kinesiologist could tell that my immune system was weak through a specific muscle test and he prescribed a homeopathic. I was supposed to take one drop a day and I misread the sheet and took two. It just about killed me (not literally, but figuratively). I stopped it after developing bad side effects and went to see him. He could see through muscle testing that 1 drop healed my immune system but 2 drops tore it down. Who would think that 1 drop would make such a big difference?
