RT Journal A1 Barker WW T1 "Mrs. potter's pure walnut-juice hair-dye"—another case of poisoning JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1909 FD March 6 VO LII IS 10 SP 787 OP 787 DO 10.1001/jama.1909.02540360043014 UL http://dx.doi.org/10.1001/jama.1909.02540360043014 AB To the Editor:  —You may be interested to hear that "Mrs. Potter's Pure Walnut-Juice Hair-Dye" is as effective in Boston as in Omaha. About two weeks ago, by courtesy of Dr. J. T. Sherman, of Dorchester, I saw an elderly woman who presented exactly the same picture as Dr. Schalek's patient, described in The Journal, Feb. 13, 1909, page 557. She stated that this was her second attack, she having been cured of the first about four weeks before at a hospital in the neighborhood of Boston. Her hair had obviously been dyed, and, when questioned, she produced the original bottle, saying that it was to her a new preparation and had been highly recommended. Each of her attacks followed the application of the dye and each responded promptly to treatment.
