2014 Reprint of 1920s Edition. Full facsimile of the original edition. Undated short pamphlet by Carey printed in the 1920s. George Washington Carey (1845-1924) was an American physician known for his 'chemistry of life' publications, a subject which he referred to as biochemistry. Carey combined a mixture of religion, astrology, physiology, anatomy, and chemistry, themed particularly with a mineral-based theory of human disease to explain his views on human chemistry. He continues to be popular within new-age and homeopathic circles. In the context of a person viewed as a "human molecule," Carey was the first to state that a person's body is a "chemical formula in operation." This very short essay is a statement of the principles of his philosophy of the cell salts.
