ICP-MS samples were prepared by dissolving the Boericke and Tafel pills in 2% nitric acid (HNO3) and internal standard. LC-MS/MS and HPLC samples were prepared from pills in hydrochloric acid (HCl). Despite being advertised as pure, the results suggest that all the Boericke and Tafel elemental pills contained a minute amount of phosphorous and zinc, but not a statistically significant amount of arsenic. The main component of the Boericke and Tafel elemental pills was sucrose, which made up about 70 % (g/g) of each pill. There was also a detectable amount of lead contamination in all the pills analyzed.application/pdfHomeopathic Remedies, Boericke and TafelHonors Thesis2021-06-18
