To the Editor:
—In The Journal, January 16, page 251, I note an inquiry about sensitization to chrysanthemums. In the answer, stress was laid on the petals as the possible cause of the dermatitis.At a meeting of the Chicago Society of Allergy, Dec. 21, 1931, I reported a case in which the petals gave negative patch tests and the leaves gave a positive reaction. The ether soluble fraction of the pulverized leaves contained the active agent.In a report in The Journal, May 16, 1931, page 1680, Goldstein reported the leaves as responsible for chrysanthemum dermatitis.I note that the inquiring physician resides in California and in this connection my patient informed me that the chrysanthemums causing his dermatitis came from that state.
