NOTE: John Uri Lloyd (1849-1936) founded Lloyd Brothers Pharmacy in Cincinnati, and was responsible for the formulation of a body of plant extracts called Specific Medicines (following the recommendations of Scudder). The pharmacy closed in the early 1960Õs, but his legacy is still present as the Lloyd Library, the largest library of medical plant books in the world, his pioneering work in colloidal chemistry, and several works of fiction, including Stringtown on the Pike (A bestseller of its day) and the mystical Etidorhpa. The culmination of his work (in my opinion) was the Third Revision of King's American Dispensatory in 1898, 2200 pages of the best PLANT Pharmacy ever assembled. When he published this pamphlet the Eclectic medical movement was moribund. Its single surviving medical school would close forever 3 years after Lloyd's death and the withdrawal by his heirs of his long-time financial support for this tattered remnant of a century-year long experiment in Medical Populism. For the last 20 years of his life, he expended his near-mythic reputation in pharmacy writing curmudgeonly emeriti-type articles in Pharmaceutical journals in futile attempts (similar to this publication) to draw his fellow pharmacists away from chemical reductionism and back into viewing plants as entities, not sources of drug compounds. That these fell on increasingly deaf ears can be surmised by his gently-ironic postscript. He was perhaps the only true American alchemist.
